Nope. Nvidia does not like to talk about unreleased products.
Which is why they were all over Pascal today, and Volta last year...

How would unified memory work on a discrete graphics card anyway? Wouldn't pci express be a huge bottleneck in bandwidth and latency?

That's what NVLink is meant to solve.
really cause they were talking quite a lot about Pascal, and even had a nonfunctioning replica (woodscrew 2.0) on stage too

Clearly shown by the Pascal talk. Oh, wait.
Will probably be a 20nm Maxwell flagship available by the time the winter holiday buying season rolls around. With Nvidia announcing the Titan Z I'd be shocked if it showed up any sooner than late September.
Pascal is not a concept nor an idea. He was literally (theoretically?) holding one on stage. 😉
Looks like the CPU has to support NVLink for it to share resources with the GPU. Good luck getting Intel to support this. It might be specifically for Denver.
Gloomy, lets not do this. You know what I'm talking about now can we leave it at that? Thanks.
A possible reason unified mem was scratched from Maxwell is that nVidia is relying on an industry standard to evolve rather than try and get AMD and/or Intel to cooperate with them. The options of including it on something other than X86 seems unlikely for the PC market.
NVidia? Industry standard? :awe:
What's their other option for X86?
NVIDIAs Pascal prototype is one such example of what a card would look like. We cannot see the connector itself, but the basic idea is that it will lay down on a motherboard parallel to the board (instead of perpendicular like PCIe slots), with each Pascal card connected to the board through the NVLink mezzanine connector. Besides reducing trace lengths, this has the added benefit of allowing such GPUs to be cooled with CPU-style cooling methods (were talking about servers here, not desktops) in a space efficient manner. How many NVLink mezzanine connectors available would of course depend on how many the motherboard design calls for, which in turn will depend on how much space is available.
But the rabbit hole goes deeper. To pull off the kind of transfer rates NVIDIA wants to accomplish, the traditional PCI/PCIe style edge connector is no good; if nothing else the lengths that can be supported by such a fast bus are too short. So NVLink will be ditching the slot in favor of what NVIDIA is labeling a mezzanine connector, the type of connector typically used to sandwich multiple PCBs together (think GTX 295). We havent seen the connector yet, but it goes without saying that this requires a major change in motherboard designs for the boards that will support NVLink. The upside of this however is that with this change and the use of a true point-to-point bus, what NVIDIA is proposing is for all practical purposes a socketed GPU, just with the memory and power delivery circuitry on the GPU instead of on the motherboard.
Why do you think NVidia is spending so much money developing an ARM core, and cosying up to IBM?

What does IBM have to do with anything?
NVIDIA will add NVLink technology into its Pascal GPU architecture -- expected to be introduced in 2016 -- following this year's new NVIDIA Maxwell compute architecture. The new interconnect was co-developed with IBM, which is incorporating it in future versions of its POWER CPUs.
"NVLink technology unlocks the GPU's full potential by dramatically improving data movement between the CPU and GPU, minimizing the time that the GPU has to wait for data to be processed," said Brian Kelleher, senior vice president of GPU Engineering at NVIDIA.

It's for POWER 8 only at this point in time besides Intel chips will not need this type of high speed (proprietary)interconnect anytime soon, as they're satisfied with ye olde PCIe for now 😛Looks like the CPU has to support NVLink for it to share resources with the GPU.
