NVIDIA G210 AND GT220
We already reported that during September this year NVIDIA can release a model number of desktop graphical solutions with video chips, which support directX 10.1, released on 40 nm technology. The corresponding mobile products were presented during June.

The chip has 24 standardized stream processors and 64- bit bus, which allow to communicate with DDR-2 or DDR- 3 memory . One G210 version will work at 600/1425/800 MHz frequencies. The cost of video card on base Of G210 will lie within the limits from $30 to $35.

GT220 possesses already 48 stream processors and 128- bit bus, which can communicate with DDR-2, DDR- 3 or GDDR- 3 memory . The memory capacity can reach 1 Gb. The frequencies of GT220 are equal to 625/1375/800 MHz. With the price $55-60 video cards on base of GT220 will exceed the speed Of GeForce 9500 GT.

^^ Any news about Nvidias plan on Dx11 gpu yet ?

[comp@ddict]

They will come by Edn 2009 or Q1 2010

^^ Any news about Nvidias plan on Dx11 gpu yet ?

it should be out by q1 2010. Ati will release there dx 11 cards before nvidia.

@ comp@ddict & ssk_the_gr8 - thanks for the info

[heaths]

Today I had a little problem with component mapping and the attributes. And It has something to do with the fact that all my objects use interfaces.

^^ What kind of post is this ??????????

[constantine]

I am not a fanboy!
i am just a fan !
i woulda put up the same comment even if i had a gtx295!!
and the reason for my 8600gt is , i was short on cash and needed a gpu ! will be getting GTX 260 or 280 in november ! ( yea i know long wait but its worth it ! )


@ gautham- how can you say no competition?
you said yourself gtx260 core 216 !
thats competiton enough! and it costs 10 - 11 k!

now hd4870 - immense power ! but extreme heating issues right ?
gtx 260 - no heating issues ! and pretty much the same performance!

but ati surprised me with 4890! i havent used the card yet ! but they say heating was not an issue on it !

now if 5890 or 5870 were to give awesome power and cooler solutions !
and were to release in october - i'd say thts great and make a suggestion to a friend to get the card ! i'd bow down - seriously!

but it seriously was a bad idea for both companies to release new cards now!
i mean most cards give good framerates and more than enough performance no new and upcoming games . right ?

so its point less for 5800s and 300s to come out now . agree ?

btw - anyone know when 300s are to release ?

[desiibond]

I don't think HD4870 has extreme heating issues. The card gets hot but that never hampered any gaming experience for gamers.

yes, HD4890 is a good card but there, GTX275 is ahead in fps.

woh said that 5xxx and 3xx is coming now. ATI and Nvidia are trying to clear existing stock and this is the main reason why ATI suddenly stopped HD4770 production.

Now that 22" FullHD monitor is avialable for 10k, many are going for FullHD and ATI/Nvidia do need to provide a sub-9k GPU that can do FullHD gaming with ease. ATI 4770 can play few games but not all. HD4850/GTS250 are now available for 7k-8k and these are good for FullHD gaming.

So, the strategy for ATI/Nvidia could be to put 40nm cards having the power of HD4870/GTX260 inside 9k price range and then release 5xxx and 3xx at 15k-18k price point.

[constantine]

Agreed!

and a friend owns 4870 . and turst me it heats up a lot , but could it just be a prob with his card ? and a review also said that the core heats up to 80 and the dual slot cooler cant keep up tht much , and air output is about 60c . not sure if this waaas the x2 version .

and arent 4850 and 260 at a pretty decent price now?
as per itwares - HD4850 1gig - 12k , gtx260 -11k

and which are the 22" monitors other than benq avail for 10k?

and i think i read in this thread that 5xxx is releasing in october , not too sure.

[desiibond]

HD4850 512meg is around 7k and 1gig is around 8.5k (not 12k/11k)

for monitor, check Samsung 2233SW for 10.5k

[comp@ddict]

^^^HD4850 is around 7k yes, but 1GB is at 8-8.2k

[constantine]

WTF! i thought itwares was cheaper !
and where do you get it for 8.5 k ? and where do you get the samsung monitor too?
i think its costlier in banglore

[desiibond]

Check in SP Road. It will be lot cheaper than what you get in itwares. Also check lynx-india.com if you want accurate pricing.

[constantine]

yea the last time i checked in sp road 260 was 12 k.

AMD ATI FirePro V8750 Workstation Graphics Card released

This now is the fastest workstation graphics card (meant for 3d desgin and not meant for gaming).

Radeon HD 4860 in the Works?

AMD released the industry's first 40 nm desktop GPU. The RV740 went on to make only one SKU, the Radeon HD 4770. The company filled its Radeon HD 4700 series almost overnight two more SKUs positioned on either sides of the HD 4770, based on the 55 nm RV770/RV790 GPUs instead, due to stock shortages. These also impacted on the inventories of the HD 4770, which forced AMD to reposition the Radeon HD 4850 in the sub-$110 segment, creating a bit of a void between it and the roughly $150 HD 4870. If anyone of you is up for yet another ATI Radeon SKU, here's one coming your way: Radeon HD 4860.

The Radeon HD 4860 seems to have been already taped out, sampled, and pictured by sections of the Chinese media. At the heart of it is the RV790 GPU in a different configuration codenamed RV790GT. It has 640 stream processors instead of 800 on the HD 4850, except that it uses a 256-bit GDDR5 memory interface, and effectively higher clock speeds. The core is clocked at 700 MHz, and the memory at 750 MHz (3000 MHz effective). The PCB pictured shows the card to powered by a single 6-pin power connector. It is expected to be positioned in at the $130 price point, and in theory, competitive with NVIDIA's GeForce GTS 250.

From the specs it looks like it will beat HD4850 in performance front & HD4850 will be replaced by it

[comp@ddict]

I wish they produce an HD4790 with these specs:-

RV740
640 SPs
128-bit Memory Interface
4GHz(QDR) GDDR5
1GB Memory
950MHz Core Clock

Such a card, say for 125$ would be a clear winner!!

Do you realize that you are talking about a card which could have serious manufacturing problems and only one in five prospective card buyers would be able to pick a card up ?

Most of AMD-ATI's 40nm GPU research has gone into making better and better cards, but their process is still being refined into something which makes enough number of cards to keep the market happy.

[comp@ddict]

Well yes, i agree on that. But now TMSC production rate on 40nm is 60% not 20% anymore.

[hellknight]

what's up with the low memory interface on all of the ATI cards?? why can't they expand it like 448-bit on GTX260 and GTX 275?? Please explain..

[topgear]

As of now GDDR5 supports 256-bit memory interface ( max ). So there is no question of 448 or 512 bit

Even with 256 bit memory interface it's equivalent to 512bit GDDR3

So with just 128 bit mem interface it's same as 256bit GDDR3 ( it used on many nvidia cards )

[MetalheadGautham]

Well yes, i agree on that. But now TMSC production rate on 40nm is 60% not 20% anymore.

60% still ain't 99% as it should be...

cheaper to manufacture lower memory interface cards. the performance drops can be gained back from else where, like using GDDR5 instead of GDDR3 and making cards more VFM.

[comp@ddict]

512-bit GDDR5 is for nVidia.

AMD plays smart, goes for Dual 2 x 256-bit GDDR5 instead in the RV870 X2 or R800 chip.

[desiibond]

whatever the specs are, in the end fps is what we take as test result. Look at HD4770. it rocks even with a 128bit GDDR5

[MetalheadGautham]

Thats for end users. BUT:

1. Like the old GHz myth, that higher means better (see athlon vs pentium wars), even the bandwidth myth exists. People tend to think that 256bit GDDR3 is better than 128bit GDDR5.

2. Lower bandwidth indeed is CHEAPER to manufacture. And that is the reason why HD4870X2 came at the price during launch of a SINGLE GTX280 and pwned the world.

[comp@ddict]

Yup, GDDR5 has become cheap to manufacture thanks to AMD, and 128-bit is dead cheap for them.

I wonder if they will use 64-bit GDDR5 in the lower end HD5000 series.

ATI Stream vs. NVIDIA CUDA - GPGPU computing battle royale

Parameter 1: Evaluate CPU usage and determine how much of the computing load being handled by the CPU with ATI Stream/CUDA enabled and disabled

Winner: ATI Stream. During our evaluation, we noticed considerable differences in CPU usage between transcoding with ATI Stream and CUDA. CUDA's average CPU usage was in the 80s, while Stream was closer to the high 60s. The extra CPU usage didn't really help CUDA in producing faster transcoding times either. So, the winner would have to be ATI Stream because it used less resources and produced faster transcoding times. It also left enough resources for users to do additional tasks during transcoding.

Parameter 2: What performance differences will consumers notice between using ATI Stream or CUDA?

Winner: ATI Stream. The performance differences between these two GPGPU technologies was a bit mixed because Stream used less CPU power and had better transcoding times, but it seemed to produce lower quality videos. If we strictly viewed just the "performance" portion of our review, ATI Stream would win because of its benchmark results during performance testing. We'll give a slight edge to ATI Stream in this portion of our ranking.

Parameter 3: Subjectively evaluate the image quality of outputted video that was transcoded with ATI Stream and CUDA

Winner: NVidia CUDA. CUDA seemed to produce a higher-quality image in two out of the three video clips we captured screenshots from. ATI Stream's outputted video was a little bit softer in a few parts of the test videos and CUDA's screenshots were brighter, clearer, and showed a little more detail overall. So, we'll give CUDA the image quality crown.

Wait a second, OpenCL mar gaya kya ? I am waiting for both ATI and nVidia to embrace OpenCL and say tata to Stream and CUDA so that we can see some interoperatability here and these guys still have STREAM vs CUDA wars ???

64-bit GDDR5 sounds possible but I think there is a higher probability of them using "normal" DDR3 (not GDDR3) memory since its fast evolving, cheap to manufacture, widely available and has low power consumption.
