Nvidia Pascal pci-e version

[Laststop311]

Since skylake-e will bring the introduction of pci-e 4.0 according to rumors is there any chance pascal will be pci-e 4.0 compatible? I know the current 16GB/sec bidirectional 16x pci-e 3.0 isn't a bottleneck now but I don't know if pascal will bring such a leap in performance that it can actually use the increased 32GB/sec bidirectional of pci-e 4.0 since they are releasing the 80GB/sec NVlink for pascal maybe it can use the bump from 16GB to 32GB/s

Q: When will PCIe 4.0 be released?
A: The final PCIe 4.0 specifications, including form factor specification updates, are expected to be available in late 2016. The timing of the specification maturity is a function of the participation and contributions of PCI-SIG members as the technical workgroups consider and debate technology choices, capabilities and analyses.

Pascal won't use PCIe 4.0 because the spec simply isn't ready and it will ship probably before the final specs are released.

Volta will use PCIe 4.0 because it will be released in 2018.

That's gonna cut it close for intel's skylake-e unless the finalization of the spec doesnt really change the controller in the cpu for it. Man I have a feeling we may not see pcie 4.0 until cannonlake or cannonlake-e even. As cannonlake will probably come out close to skylake-e and if intel cant finalize the cpu portion of pci-e 4.0 until its actually finalized we may not see it in intel until their 2017 chips cannonlake-e and whatever the 2017 10nm tock for mainstream is.

That makes me sad as I am not upgrading my next build for a minimum of 6 years but shooting for a full decade and I need pci-e 4.0 and usb 3.1 support built into chip since I am keeping this a long time and spending 4000. Man o man i may have to keep my i7-980x build another extra year till cannonlake-e. Will be almost 8 years old by the time i upgrade. At least I got my moneys worth outta it. The cpu still isn't a bottleneck for almost every task. Really I'd keep it longer but ultra m2 slots with killer nvme ssd's are really forcing the upgrade for me. Need 2x ultra m2 slots preferably or the 1TB 3d v-nand version of the nvme sm951 if I can't have 2 ultra m2 slots.

4000 what? USD? may I suggest spending 1000 every 2.5 years instead of 4000 once to last 10?

Sandy Bridge E was suppose to be PCI-e 3.0 the RIVE board wasn't and you had to enable it. They will probably state PCI-e 4.0 capable.....

always "wait n see" on a new plate form, IMHO.

Heed this man's wise words!

Although to be fair, an Intel 980X is still a very powerful CPU. With an SSD and a good video card, I doubt you'd notice any difference in most games.
