[VC] NVIDIA announces Pascal architecture - Page 2

post #11 of 38
NVLink will allow NVIDIA to build double GPU cards more easily?


(I assume it is really for GPGPU.)

Odd. I thought that was a big part of Maxwell.

Yeah, Maxwell was unified memory while Volta was stacked memory. I clearly remember them talking about this.

As do I, but things change, and we just have to go with that.

I was hoping to see a sneak peak of the new 800 series, oh well.

While it is certainly aimed at GPGPU, I wouldn't say it isn't aimed at the gaming market.

Improving SLI scaling would be a very nice thing, and the memory bandwidth improvements? All good things for gaming. Maybe a gamer with two mid-range cards in SLI doesn't care as much as someone buying the $50k Iray system they showed off, but it still will make a pretty big difference for gaming.

Stacked memory is definitely something to be excited about. Difficult to contemplate the possibilities it opens having that much bandwidth.

Hm... Looks pretty bad ass.

All of the implications of this and potential is giving me a heart attack, along with the rest of this day's news and GDC's prior...

No 20nm product preview was disappointing.


Unified Virtual Memory is already present in the latest CUDA 6 RC for all supported cards, intended for CUDA purposes all along no doubt as most prior listed capabilities on the roadmap. It's not really much use to us but for speeding up developer workflow in CUDA. We're even getting it in some Kepler cards. Nothing prior listed for Maxwell has been moved onto only Pascal here. What Pascal will feature is true unified memory however, which is going to be utterly insane. A NVLink port inclusion is very interesting as the faster, preferred alternative to PCIE3 (6-10 times faster at 80GB/s) for future Pascal "modules"?

Interesting, however they should be talking about Maxwell. You know details, release time frames that kind of thing.
post #20 of 38
It's Volta renamed. NVlink is practically improved SLI.

I suspect nvlink goes first before even Volta since it can be done and it might be another bargaining chip for marketing between process shrink stalls.

Stacked VRAM will require Pascal since it is always described as something that sits on top of specialized GPU connectors, so, well, even if it comes before it, it's a shift in GPU paradigm, can't be used now, that's for sure.
