how much fps performance can i expect going from a 680 to a pascal ? QUOTE(skylinelover @ Feb 7 2016, 11:53 AM)
if not mistaken i heard the timeframe from pascal to volta may be somewhere between 1-2 years QUOTE
Meanwhile Volta has been pushed back and stripped of its marquee feature. It’s on-package DRAM has been promoted to the GPU before Volta, and while Volta still exists, publicly it is a blank slate. We do not know anything else about Volta beyond the fact that it will come after the 2016 GPU.
Which brings us to Pascal, the 2016 GPU. Pascal is NVIDIA’s latest GPU architecture and is being introduced in between Maxwell and Volta. In the process it has absorbed old Maxwell’s unified virtual memory support and old Volta’s on-package DRAM, integrating those feature additions into a single new product.

With today’s announcement comes a small degree of additional detail on NVIDIA’s on-package memory plans. The bulk of what we wrote for Volta last year remains true: NVIDIA uses on-package stacked DRAM, allowed by the use of TSVs. What’s new is that NVIDIA has confirmed they will be using JEDEC’s High Bandwidth Memory (HBM) standard, and the test vehicle Pascal card we have seen uses entirely on-package memory, so there isn’t a split memory design. Though we’d also point out that unlike the old Volta announcement, NVIDIA isn’t listing any solid bandwidth goals like the 1TB/sec number we had last time. From what NVIDIA has said, this likely comes down to a cost issue: how much memory bandwidth are customers willing to pay for, given the cutting edge nature of this technology?
QUOTE
Finally, NVIDIA has already worked out some feature goals for what they want to do with NVLink 2.0, which would come on the GPU after Pascal (which by NV’s other statements should be Volta). NVLink 2.0 would introduce cache coherency to the interface and processors on it, which would allow for further performance improvements and the ability to more readily execute programs in a heterogeneous manner, as cache coherency is a precursor to tightly shared memory.
Wrapping things up, with an attached date for Pascal and numerous features now billed for that product, NVIDIA looks to have to set the wheels in motion for developing the GPU they’d like to have in 2016. The roadmap alteration we’ve seen today is unexpected to say the least, but Pascal is on much more solid footing than old Volta was in 2013. In the meantime we’re still waiting to see what Maxwell will bring NVIDIA’s professional products, and it looks like we’ll be waiting a bit longer to get the answer to that question.
