How much transistors will be in PS3's GPU ?

[version]

256 million for 32 MB edram and 256 million for logic

 

[GwymWeepa]

Using my powers of pure ignorance, I'll say around 500mil.

 

[jvd]

doesn't the nv40 have 333 million transitors ? I wouldn't imagine the ps 3 gpu being less even if they don't put in vertex shaders .

NV40 is 222 million transistors .. but, as you said, PS3 's GPU , being based on NVIDIA 's next generation GPU, will most certainly have more

 

[Shinjisan]

It will be built at Sony's new fab which is 65nm so 800 million transistors.

 

[jvd]

ah thank you , 333 is close to 222 haha .

But yea i see more than a 27m tranistor increase u know

if 800m then the die size is 600mm2 on 90nm, on 65nm 300mm2,
it is possible?

you bring up a good point .. NVIDIA's GPU may indeed be fabbed @ 65nm;

as I partially posted in another thread; we know Sony is getting their fabs ready for 65 nm production [( http://www.eetimes.com/semi/news/OEG20030421S0071 ) and ( http://www.eetimes.com/semi/news/showArticle.jhtml?articleId=20900206 )], and since now we know that Sony is fabbing the NVp GPU, "The custom GPU will be manufactured at Sony Group's Nagasaki Fab2 as well as OTSS (joint fabrication facility of Toshiba and Sony)." [ http://www.nvidia.com/object/IO_17342.html ], the NVp GPU definitely has a chance of being fabbed @ 65 nm ....



if so, then not only would the GPU have a process advantage over the Xbox2's GPU [it is highly unlikely that TSMC (TSMC has signed on to do fabbing for MS: http://www.gamesindustry.biz/news.php?aid=3263 ) will have their 65 nm process ready in time to make any of Xbox2's chips using a 65 nm process] which may not only allow Sony/NVIDIA to jack up the clock speeds on their GPU, but as you suggest, Sony could afford to put in a lot of on-die RAM on the chip as well..

man those sony plants are going to be making alot of crap. Lets hope there are no problems with them

 

[j^aws]

My guess is that the GPU will have roughly 3x more trannies than the CPU, like the current EE and GS...so I chose 800 million.

Damn Jvd, why are you always so negative about any Sony related things?

 

[overclocked]

I guess 400-500million transisitors in the GPU, at 90nm that would make it as big as the NV40 but a quick shrink to 65nm would make it half the size of current 130nm NV40.

 

[Megadrive1988]

NV40: 222 million transistors
R520: ~300 million transistors (?)

PS3 GPU: 400+ million to 600+ million transistors.

 

[PiNkY]

357,899,768.27 ... but don't tell anybody

 

[cthellis42]

The need the extra .27 to take them over that elusive FLOPS number, eh?

 

[London Geezer]

The need the extra .27 to take them over that elusive FLOPS number, eh?

No, that .27 fraction of a transistor is what will give the chip a 25nm reputation (90nm x .27 = 24.3nm). People will look at that single transistor and go ITS A 24nm PART!!!!

 

[Fafalada]

294.912 M transistors for logic (come ON now, you all knew that was coming ), + whatever the eDram comes down to.

 

[PC-Engine]

Whatever the transistor count turns out to be, 1 Nvidia TFLOPS GPU + 1 SONY TFLOPS BE = 10+ Nvidia/SONY TFLOPS PS3...
