잡담 저가형 안드로이드 기기에 들어가는 CPU인 TCC89xx, RK2818, IMAPX200 비교글..
2011.05.30 11:55
KPUG에서 많은 사람들이 가지고 있는 Gpad G10의 CPU인 TCC 8902와 앞으로 리뷰할 기기에 들어가는 RK2818 그리고
전에 Zenthink ZT-180이라고 불리면서 10인치에 큰 스크린을 자랑했지만 가격이 저렴한 타블렛에 들어가는 IMAPX200에
비교 분석글입니다.
글이 짤릴지 몰라서 그냥 긁어서 올립니다.
짧게 요약하면 RK2818의 경우 720P까지 지원하지만 MKB의 재생능력이 조금 떨어집니다.
(동영상 부분은 일반적이다라고 보면 됩니다)
물론 3D 기능은 형편없구요.
단 2D쪽과 시스템의 안정성, 그리고 UI의 속도는 셋중에서 가장 뛰어납니다.
TCC89XX쪽은 1080P까지 지원하고 3D도 어느정도 지원을 하고 안정성도 나쁜편이 아니며 3D나 2D쪽도 어느정도 지원을 하며
웹 브라우징 속도도 RK2818과 어느정도 비슷합니다. (말 그대로 범용칩이죠~~)
IMAPX200의 경우 CPU속도가 압도적이며 (1GHz까지 올라가니까~~) 해상도 지원도 빵빵하게 하며 3D에 강점을 가졌지만
인터넷 브라우징의 경우 극악의 로딩속도를 자랑하며 시스템 안정성도 부족한 편이라고 합니다.
Three low-ends dull and stereotyped chip is compared with (RK2818/TCC8900/IMAPX200) horizontally
In the dull and stereotyped scheme of the mainstream at present, Cortex A8/A9 framework is undoubtedly the target who reputable player pays close attention to, but go back to look in 2010 that just passed, the stage of development that China MID market is basically at starting, the products of ARM9, ARM11 framework are lower because of the whole price, accord with the users of masses’ purchasing power level further, what a lot of consumers touched is still the ABC of model of this kind of low-end. The plateform is examined and specially directed against ARM9, ARM11 top management scheme sideways this time.
Article of this page is divided into three big parts, including: Select scheme and parameter introducing and detailed contrasts of characteristic in many aspects of corresponding to the products, selecting the model rejected sideways. The advanced person below enters the first part:
Dull and stereotyped scheme used for commenting sideways and corresponding to the products to choose – -
Though Chinese market every low-end of brand dull and stereotyped quantity numerous, count accurately, stand up ARM9 that adopt, ARM11 punish chip have several very fewer only, not coming abundantly as Cortex A8/A9 camp far, it is a difficult inverted trend to replace the old framework core gradually out of date by the chip of more advancedly instruction set, the foreign chip has been already developed to a lot of manufacturers to ARMv7 A8/A9 has been all Research and development stage,last one step. And China IC designing trader at 2011 year too gradually in A8, set out stage A9, the dull and stereotyped chip of ARM9, ARM11 framework and nothing more than representing the products a little that it can be found at present that:
The intersection of Weisheng and
WM8505/WM8505 ARM9, 300MHz/400MHz, 128MB DDR2, 16bit, there is not 3D

Lankan ePad, country is beautiful to fly and touch 2 generations
On-chip several above-mentioned style, Weisheng WM8505 is low because of primary frequency, such reasons as the memory is little, the video ability is weak, overall performance is quite bad, have basically already faded out in the major visual field at present, so no longer join the contrast, subsequent WM8650 chip does not have relevant products to go on the market temporarily, are excluded too; Samsung S3C6410 device Q series MID already stops production at present, does not include in the range no longer intelligently. RK2808 is limit to the applied SDRAM memory, and stay in the old system of Android 1.5 as first little plateform top management of auspicious core, also no longer single contrast. Examine, choose, have many RK2818, TCC8900, IMAPX200 3 sections of chips to correspond to product compare at market at present sideways this time, state briefly one by one as follows.
Talk about RK2818 first, this is a main scheme in the little market at present of auspicious core following RK2808, compared the former though primary frequency was not obviously promoted, but the memory staging makes the running speed much more smooth to 256MB DDR2, carry Android 2.1 system at the same time, improve in the compatible respect of the software too. The auspicious core is little should or invest a lot of research and development efforts on this platform, make relevant product of RK2818 operate, react in fundamental interface and the intersection of system stability and display fairly permitted. But it is the highest that its video broadcasts ability although can reach 720P, the support to MKV is not good, at the same time 3D in ability for their to ribs soft,there are problem that it condemn too on this point. Because own completeness great of RK2818 scheme that the auspicious core offers a little, has in addition, been cooperating with it all the time closely in many terminal stations manufacturers, the products of this scheme are being put out, mostly adopt resistance of 7 inches screen on the Chinese market constantly, the model that some matching electric capacity rejects appears too now, and the manufacturer turns over the memory time, make every effort to have new promotion in speed, but this obviously tackles a problem on the surface, not at the root.
And then see Telechips TCC890X chip of the lower ARM11 framework, TCC8901 of this series is applied to the whole high definition MP4 extensively as far back as 2009, and device use TCC8902 type, produce several the intersection of MID and model early too, support system including Android, Ubuntu, WinCE intelligently, but unpopular, until will it be dull and stereotyped when in great outburst 2010 the second half year, TCC8902 chip really adopted extensively. The advantage of its maximum should be to support 1080P of many forms to be smooth and hard and is decoded, but should be because of lacking trader’s sufficient support of the chip, not very very good all the time in system optimization, the whole running speed does not dare to flatter. 3D characteristic should be stronger than RK2818 in terms of the hardware, but drive and improve degree discrepancily, it is general to behave actually. In term of present market current situation, a lot of small manufacturers rather favored this chip, the relevant products are innumerable too. Note: According to materials consulted, the difference between TCC8900 and TCC8902 lies in it is different that the integrated interface enriches the intensity, the characteristic is basically concerted
The intersection of ultimate analysis and lower the intersection of IMAPX200 and the scheme, it full of square little reputations to be though big, the frequency can fry chip to move to 1GHz burning hot at one time. It can support 1080P hard to solve in video, the intersection of itself and 3D accelerator that can fairly have too. But not enough to optimization degree of the system, do not have big brand that put out the corresponding products now, the present model is basically that the not high mountain fastness of quality is produced for the factory, there is more BUG on the hardware, the whole power consumption is very great too.
In sum, compare with and assess and test and choose Owen N3, device R10 intelligently and Jone Sri Lankan ePad these three products horizontally this time, though say it may not be loud enough from name, this is exactly epitome that China leans towards the dull and stereotyped market of low-end, what there is no big international brand sets foot in, the majority is the products of the small manufacturer of native country, do not lack the white brand model of mountain fastness even more. Certainly, the brand is not the most important factor, the characteristic determines to use and experience. Even if these schemes are not given strength the exposing successively of Cortex A8 top management, but little, there should be greater change within annual back several months while packed with ARM9/11 current situation for the strength products ing on the market of low-end.
To see three product basic parameters of downing and participating in and comparing with horizontally – -

Appear a bit more ocular with chart form – -
According
to data above, the memory of three is of the same size, systems running
are all Android 2.1 editions too, but it is the highest that primary
frequency belongs to Sri Lankan of Jone, and the disposition difference
of the screen is greater.
Now enter concrete characteristic PK links – -
First, hardware characteristic are compared with and tests
The
influence in factors such as system customizing, Java Virtual
Machine,etc., compare with the test result part only for reference as
follows, do not make the basis of the true characteristic PK. Before the
hardware test, Owen N3 and device R10 intelligently are all firmware of
the first edition official side has not offered the staging temporarily
,Jone Sri Lankan ePad has been already staging to the newest firmware
of 1204 official side.
The testing tools of
seven hardwares can not all run on the products of scheme of this top
management, so the test result obtained looks a bit incomplete. Carry on
the simple explanation to each project.
1. used for testing the
top management chip for floating point arithmetic capability in
Linpack,there are to last gausses of elimination method solving N
systems of linear algebraic equations dense onces unary on test
philosophy of it, thus appraise the floating point characteristic of the
top management chip. This test result is influenced by Java Virtual
Machine efficiency, so consult only as one.
The test results of RK2818 and TCC8900 are similar, IMAPX200 is obviously more than one time higher.
2.
simple for ocular testing software,pass operation 10 algorithmic
routine it, CPU appears in test ‘ Integer , FPU floating point And the
characteristic of the memory, free of Java Virtual Machine efficiency,
so the test result presses close to and behaves the true characteristic
of the top management chip even more, there is certain reference value.
Three test results of Nbench are all and then increased progressively from RK2818 to TCC8900 gradually to IMAPX200.
3.
J Bench Mark is in having been test by top management chip for loads
direct of storage spaces built-in and read under buffering by
situationing, will be influenced by independent USB control device, so
this test result is only for reference.
The result
reflected in this test is not accurate, the actual reading speeds of
RK2818 and TCC8900 are about 10MB, the intersection of and the former of
load fewer than 4MB, the latter can reach 7MB the above-mentioned, this
is U6 test result that TCC8900 compares with coolness of serial schemes
. Jone Sri Lankan ePad full of the square little scheme has not opened
USB to read directly too, has added the built-in only 2GB storage
space, it is not too important to read and write the speed, but depend
on the speed of media reader that you adopt. By the way say the filing
system respect, three models can only support FAT or FAT32 form, though
TCC8900 and IMAPX200 possess the whole high definition film and
broadcast ability, wants to watch that it is different to realize to
exceed 4GB size video file through the products.
4. Neocore is a
figure characteristic basic reference testing software based on OpenGL
ES 1.1, can find out 2D/3D comprehensive handling capacity of the chip
from this test result, the test result is represented with a lot of
frames per second.
The products of TCC8900
do not support this testing software, it is seen but experience from
in-service use, it is low that the frame rate may not be more square
than to full of and little, how high result of natural 10.3fps is not,
3D picture looks at such a speed that there is obvious frame dropping
too. RK2818 fewer than 2 behavior of frame, shown and has not offered as
a gift the intersection of figure and soft rib of ability its.
5.
as its name suggests in GPU Bench for figure processor benchmark
test,there are for absolute value on one test results, one is relation
size, score in other words, the simple score of seeing a certain chip is
nonsensical, will not find out unless see comparing with which one is a
little stronger. This software is unable to run on the above-mentioned
three platforms.
6. Benchmark is it is synthetic one pieces
characteristic testing software,it can last figure characteristic, CPU
characteristic, memory characteristic and file system performance,etc.,
the test result is influenced by jit compiler, so can only be for
reference.
The simplicity is according to this
software, the figure ability of the three is similar, this, obviously
with the real discrepancy. CPU handling capacity, IMAPX200 mark is
obviously one or two times higher, this should benefit from its more
high master frequency. Memory characteristic and filing system, the
whole difference is not big, the TCC8900 one should be a little higher.
7.
too in Quadrant for one section all-round property testing
software,there are getting more overall very on result that be tested,
and more authoritative. It can test CPU, memory, Input/Output, 2D, 3D
and comprehensive result, and can carry on the contrast of scoring with
the platform scheme of the mainstream at present on the market.
The
products of RK2818 are all unable to operate this sincere software, so
only compare other two schemes, the result is as follows:
Score synthetically: Telechips TCC8900> is full of square little IMAPX200
CPU scores: Telechips TCC8900<is full of square little IMAPX200
The memory scores: Telechips TCC8900> is full of square little IMAPX200
Input/Output: Telechips TCC8900> is full of square little IMAPX200
2D scores: Telechips TCC8900<is full of square little IMAPX200
3D scores: Telechips TCC8900> is full of square little IMAPX200
Two chips as ARM11 framework, the whole score of TCC8900 should be a little higher, and CPU ability of IMAPX200 is even better.
In
general, the result of the chip has basically reflected the handling
capacity of various fields, but run and divide and is only for
reference. Actual motion result and software compatible ability easy to
reflect in order to operate smooth degree as the example in data, though
most test results of RK2818 do not behave so well as TCC8900, to
operate the obvious feeling is more smooth than the latter.
Second, video decoding are compared with and tests
RK2818
adopt independent the intersection of DSP and video decoding, nominal
to can support to 720P while being highest; TCC8900 hard for CPU solves
the video, can support 1080P the whole high definition to broadcast;
IMAPX200 decodes for the hardware too, the highest can reach the level
of 1080P too. By the look of parameter only, RK2818 should be obviously
in leeward. Display and to see the concrete test result actually.
In
view of TCC8900 being hard to solve ability to be high in itself in
scheme and IMAPX200, basically need to broadcast most videos through
third party’s player, so two product of scheme these test decoding
capability using player of the self-carrying directly, I have not found
one yet appropriate and softly to solve the player of the video under
RK2818 platform, RockPlayer is unable to turn on the video, VPlayer does
not support Android 2.1 system, so test using decoding that the player
of the self-carrying carry on too.
In case of that individual
feels, MID scheme of the auspicious core little series RK28 emerges from
the womb of their Er early MP4 schemes in audio-visual function, been
staying in the level of the highest 720P all the time, the incorporating
of but Android has not offered as a gift and tied down decoding
capability, first it is auspicious to regard as core high definition MP4
the H.264s of selling points little decode,it behave in planes dull and
stereotyped of RK2818 in a complete mess too, only these two forms of
AVI, RMVB are also to 720P by better support. TCC8900 has the same
origin with Telechips previous complete high definition MP4 scheme too,
but its decoding capability has not been offered as a gift and is well
extended, there is no obvious decline. The decoding capability which is
full of square little IMAPX200 is more pleasant, basically keep the same
with TCC scheme level, specific slightly a little worse. The
intersection of whole and speech, the two roughly the same, fail on
numerous top management scheme of Cotrex A8/A9 never, but RK2818 is far
got rid of behind.
Recognition and subtitle supporting respect
of many audio tracks, the self-carrying players of three products do not
support the audio track to switch over, the built-in and all kinds of
strap-on subtitle can’t be loaded either, this is a common fault some
manufacturers can be supported after optimizing on Android products at
present, such as loving visual ARCHOS 70 . Regarding these three
platforms, have not found yet the model with these functions appears at
present, there is relevant required that is can only be that the
installation third party’s player is realized, RockPlayer can be chosen
many audio tracks, and mVideoplaer can support the polytype subtitle
file.
Third, speed of turning on/off device are compared with and tests
The
mobile equipment turning on/off device which adopts the intelligence
system will not often be finished in a moment, it would obviously
influence mood very much if it is too slow. But regarding platform, the
enough average level to represent all products either of speed of
turning on/off device on a certain product only, can only consult as
one. Correspondent dull and stereotyped systems of these three chips are
all Android 2.1, the turning on/off device speed tests and carries on
in case of not installing a lot of software. Test it from pushing the
starting up key to this section of time intervals totally loading the
systematic Main Interface, shut-down tests from clicking the
communication frame that downs and confirms shut downing to the black
time interval that rejects of screen.
The products in the
little RK2818 platform of auspicious core are started fastest, the
varied products used before this are almost such a level too. Products
of TCC8900 want a lot of slowly, shut-down speed most quick, shut-down
of other two speed difference strong.
Fourth, whole scheme power consumption is compared with and tests
Respects
such as battery magnitude of different models, circuit design,etc. have
a difference, break away from the concrete products and discuss the
power consumption is obviously unrealistic. From experiencing and
feeling that says, generally it is shorter than the time that the video
broadcast to hold the continuation of the journey that WiFi surfs the
Net actually, open consumption behind the WiFi besides CPU this one, the
intersection of itself and wireless power consumption of chip, it is a
power consumptive rich and influential family to look like the Realtek
net card that Jone Sri Lankan ePad adopts even more. This power
consumption compares with and lays particular emphasis on the comparison
to the top management scheme even more, so with the flight duration of
video in order to consult. Three machines adopt the player of the
self-carrying to broadcast the same video file AVC code in a circle,
704* 432 definition ,Test, in unison for identical the intersection of
arrangement and parameter sound volume / in a poor light to adjust for
being half the, close WiFi, use the earphone to play .
The
average power consumption index is to adopt the total amount of the
battery and video flight duration to deduct the result made, the less
the figure is, the lower the power consumption of representation unit
is.
The factor influencing power consumption is numerous, three
sections of screen magnitude of testing the products are different from
definition capital, the consumption of large screen should be obviously
higher than the small dimension products, in addition if the homogeneous
scheme adopted different power management chips, should have difference
too continue a journey. Wouldn’t consider other factors, only so far as
form, the products of RK2818 undoubtedly have the relatively lowest
power consumption, the really continuing a journey incredibly long of
N3, in the varied and scheme products that I have used, calculate the
very strong one too in Owen N3′s continuation of the journey ability, so
the continuation of the journey ability of this link N3 can’t totally
represent the major level of this platform either. Jone Sri Lankan
flight duration of ePad most short, until back over its generate heat
intensity can feel it consumption large too use. Device R10 is the
continuation of the journey that can fairly gain with high-capacity
battery intelligently.
Fifth, speed of response of the menu and stability contrast
The
speed of response of the menu is involved in many kinds of factors,
besides treatment characteristic of one’s own top management, the
assembly of the touch-sensitive screen and optimization of the system of
manufacturer influence really border is operated and experienced.
Stability is influenced by improving of the system firmware more,
certainly relate with circuit design too. This has more subjectivity,
none of objective measurement standards to compare with, the following
is the correlation data a representative is relatively best obtained on
the basis that my use feel, 2 takes second place, 3 rows of end
,Subjective contrast, are only for reference.
Because
of using the products of varied RK2818, run to experience more
extensive cognition to it wholly, the plateform of TCC8900 has contacted
several too, running speed should be obviously inferior to RK2818, the
sequencing of these two does not basically need to consider too much
that can be obtained. And the model of IMAPX200 has Sri Lankan ePad this
one of Jone only at hand, running speed and stability of touching 2
generations should be a little more outstanding that it is reported to
fly, but examine sideways this time since select ePad, is based on it
first.
Three machines are Android 2.1 systems, and possess the
memory capacity of 256MB too, but because of the difference that is
taken up systematically, reality can spend the memory RK2818
respectively ‘ About 200MB >IMAPX200 about 185MB >TCC8900 about
155MB ,And the surplus memory of runtime regards RK2818 as maximum.
Though there is not direct relation in memory magnitude and running
speed, if the surplus memory will obviously influence the smoothness
operated to pass littly. As for the intersection of stability and,
though RK2818 to rank the first, can’t say it stability right away
getting OK too, crash in fact, flower reject occur repeatedly at the
intersection of N3 and the products too, just comparatively speaking.
The system halted situation of the device R10 is a bit more frequent
intelligently, but Jone Sri Lankan ePad is not complete enough because
of the system, the frequency that the procedure collapses is larger
while using.
Sixth, browse through the speed contrast of the webpage
Three
machines do not support the webpage Flash to reveal, tests the speed of
opening iMP3 homepage using browser of the self-carrying separately,
and the one that looked over and pulled is smooth.
RK2818 and two products of TCC8900 load the webpage speed similarly, it takes about 20 seconds to open the homepage, the latter is slightly a little faster. Jone Sri Lankan ePad of IMAPX200 has nearly had another time time consumingly. Pulling the smooth respect, Owen N3 supporting the multi-point to touch preferably behaves, but not smooth enough while zooming, device R10 slip, compare Carlos when being met the long page intelligently, the Carlos when Jone Sri Lankan ePad pulls often, there is feeling of a kind of frame dropping, the result is not smooth enough, are stated to fly and have many improvements to touch 2 generations separately, because has not seen the real machine, not easy to make more conclusions. Now choose two browser characteristic testing softwares to compare with the efficiency of these three products, the result is only for reference:
Acid3 mainly investigates to the canonial implementation of the webpage, especially DOM and JavaScript, it is perfect to lay particular emphasis on, the higher the preceding figure is, the better the preceding figure is, iPad result is 100/100, Owen N3′s result is 91/100, device R10 and results in Jone Sri Lankan ePad are all 93/100 intelligently.
Google V8 benchamark
suite is used for testing JavaScript characteristic of the browser,
optimizes for Chrome browser specially. Can reflect the browser
characteristic of this apparatus to a certain extent, score well the
better, iPad result is 82, Owen N3′s result is 37.8, the device R10
runtime has been blocked in 89% all the time aplanetically
intelligently, the result of Jone Sri Lankan ePad is 48.7.
Seventh, game characteristic contrast
The
game characteristic lays particular emphasis on the contrast of 3D
figure ability, can be found out from result of Neocore at the time of
the initial hardware test, RK2818 it fewer than 2 result of frames to be
obviously unable with run, divide, up to, contend by 10 IMAPX200 of
frame, and TCC8900 because unable to run software this, how much unknown
frame can be run, but according to experience definite and eager to
excel in whatever one does to produce much than that of RK2818. Consider
on the basis of the hardware respect, has not announced GPU
specification adopted in the technical parameter of RK2818, the player
claims it plays up 3D picture through ARM core, so will cause very
slowly; 3D of TCC8900 accelerates some as ARM Mali-200, one’s own
hardware is good, but seem that it is not complete enough to drive; It
is VIVANTE GC600 to be full of little 3D squarely and accelerate, and
TCC8900 support OPENGL ES2.0/1.1, OPENVG both, it compares focal points
with to be still two house PK of chip these this time.
I choose varied game go on, test to three machine these, break out loudly such as Sparta, dungeon hunter a lot now certainly Return run, has only brought a minor city raceabout 5 to see the result. Hot game under the Android at present, lay particular emphasis on, can examine the intersection of gravity and reaction, the intersection of 3D and characteristic even more certainly, the game that the picture such as chess, poker is very simple has tested that has few meanings too.
Jone
Sri Lankan ePad existing problem to have a surplus of square little
IMAPX200 chips is that the gravity reaction is invalid, not because
direction work, but itself which direction can move, in 3D
characteristic can it finds out to be fairly strong one under these
style; TCC8900 the intersection of device and R10 and behavior of it
close comparatively while being overall intelligently, turn on the
varied games and appear the phenomenon of crashing, more troubling; 3D
characteristic of the auspicious core little RK2818 is undoubtedly the
worst, this does not basically need to explain too much either.
Written at the end
When
major Android intellectual mobile phones all generally employ the
situation of Cortex A8 processor, Android plateform with large screen
has proposed more high requirement to the hardware disposition too, and
ARM9 and ARM11 have already lagged behind from the framework, while
player’s requirement is higher and higher, the nuclear products begin to
assault the market of low-end too in batch white brand A8, the low
price advantage of ARM9/11 kernel products is lost gradually too, and as
to these three products that this selected works select, Owen N3 and
the devices R10 can not be all counted as the absolute low price
intelligently, though similar many products it drops six seven to to be
hundred yuan even low already, characteristic remain very much difficult
to attract the reputable player while being low, we can say it is more
and more unstable that this kind of products are based on the foundation
the market.
RK2818, TCC8900, the intersection of IMAPX200 and
three chip these come comparative synthetically, which obviously strong
style does it have, because the three all have a prominent shortcoming.
The advantage of RK2818 lies in being relatively stable and smooth, but
3D characteristic is too bad, the video ability is more general; The
advantage of TCC8900 lies in video decoding, but 3D characteristic is
not complete enough either, speed and stability are still more not to
dare to flatter; Have IMAPX200 at present it is large adopt
brand,mountain fastness model where the manufacturers produce no matter
mould, work and stability is getting good more enough.
Certainly,
these manufacturers which research and develop ARM9/ARM11 mobile
platform have not awaited one’s doom either, can see since CES
exhibition they are growing with each passing hour constantly too. At
present, the auspicious core is little to release the nuclear RK29XX new
platform in Cortex A8, nominal primary frequency achievable 1.2GHz,
there will be very great leap by the look of hardware parameter. And
Telechips brand-new TCC8903 is based on A8 kernel, it looks that overall
performance will be promoted notably, it is believed that these
products are relatively worth expecting. However, the relevant products
are very difficult to really put out the market before annual spring, we
will continue waiting patiently.
Also need to prove about this
assessment and test, because mainly experience the respect to compare
with from employing, among them unavoidably mix subjective factor, there
is style of writing in wrong, welcome to make a comment. In addition
read application respect to the e-book that some players cared about,
this have something to do with hardware platform, but different one
reads the software and behaves not the same, it is difficult to carry on
the comparison objectively, so has not joined this partial content
while examining sideways.
