Rumor: Nvidia G300 to be big, hugely powerful

[iml3g3nd]

Last we heard, both AMD and Nvidia were prepping next-gen graphics processors for the fourth quarter of this year. The guys at Hardware-Infos now say Nvidia has taped out its upcoming G300 graphics chip, and they’ve posted some specifications for the product.

If the Google translation hasn’t warped the post’s meaning beyond recognition, Hardware-Infos says the G300 will have 512 stream processors, almost 2.5 teraFLOPS of number-crunching power, 1-2GB of memory, and 281.6GB/s of bandwidth. The memory will supposedly run at 1,100MHz, so assuming GDDR5, that would mean a 512-bit interface width.

As for the gigaFLOPS figure, the site goes on to say the G300’s stream processors are no longer SIMD elements but “MIMD-like” (multiple-instruction, multiple-data) units. That could imply more complex, more flexible hardware, although the report doesn’t talk about gaming performance.

With that said, a graphics processor with that much floating-point power and memory bandwidth probably isn’t going to be small. And indeed, a previous post from the same source talks of a whopping 2.4 billion transistors—a billion more than the GT200.

So nVidia still betting on big, badass, monolithic GPU… hmmm.

But GDDR5 on 512-bit bus sounds too good to be true, correct me if I’m wrong but doesn’t bus get complex as width is increased? I think I had read so somewhere, that, that was one of the main reason why ATi stuck to 256-bit bus for GDDR5 on 4800 series cards, as it was too complex to get GDDR5 working on 512-bit bus and ATi needed to get product out fast.

Looks awesome on paper..

ati sticking to 256bit was more due to economies than complexity (and maybe pad limitation),its all about trade-offs.
If there is 2x increase in compute performance (and since nv is still looking for ultimate perf),you dont really want to be held back by slow memory.

Huh…Nvidia, just rumour. It can be Nvidia’s marketing tactics, to create speculation from now only…

[demonic]

let’s just keep our fingers crossed and hope that this rumour proves true

if rumours r to b true…dan it wl b one of d biggest beast in GPU history one hs evr seen…dnt knw hw much gaming perfomance wl improve wid all dis brute power but gpgpu programs wl definitely tk advantage of such raw power…
