[TH] PCI Express 4.0 Brings 16 GT/s And At Least 300 Watts At The Slot - Page 15

The more I search, the more I feel as if I should hold off from spending money right now to either get an x99 mobo + cpu + new ram as well as not spend $150-300 usd on a x58 mobo again



But instead reallocate whatever resources I would have and just wait til sometime next year for skylake E or X, if at that point I'm still not satisifed at least the resale value would be greater than an x99 or x58 system I would have other wise and I could get a better return on selling it on amazon or ebay.


My only question for you guys is, even though none of us really know the absolute answer to this, would it be safe to assume we'll see mobos for a skylake E or X cpu that has a PCIE 4.0 slot sometime in 2017? If so then that will really solidify my choice to wait til then

Skylake-E is worth waiting for. PCI-E 4.0 is not worth waiting for.

definitely not, even with 3.0 x16 compared to 2.0 x16, theres hardly any different for GPUs.

however, if it was used for data, a mere 4.0 x1 will have enough bandwidth for your typical PCIe SSD.

Yeah I wasn't exclusively mentioning the use for graphic cards, but for all applications. And for a resale value, I can only imagine having a PCIE 4.0 board would sell better than a 3.0 if provided the same features

If I were to guess I would say yes, Skylake-E or Kabylake-E (if they do a Kaby enthusiast chip, didn't do a devils canyon enthusiast chip so not sure) will be the debut for PCIE 4.0 on the consumer side of things, just like DDR4 debuted on Haswell-E

There is seriously some grotesque shortsightedness in here. "Let's not even bother making a new standard until after we start hitting the wall with what we've got" is all I'm hearing. This can only be good.

rather than simply pushing for higher bandwidth with minimal benefits in mind, why not make a revision targeting payload overhead efficiency or reducing latency?
for example, things like increasing the PCIe base-clock from 100Mhz to 200Mhz would halve access latency.

as good as PCIe can be, its still inferior to DIMM slots, otherwise we'd be using PCIe RAM instead of DIMM RAM.

I'll take them staying ahead of the game over the route HDMI has gone and be about 2 generations behind all the time.

Pretty sure I read there's going to be a 4 core Kaby Lake X and 6-8-10 core Skylake X for the enthusiast platform, whether this includes PCI4.0 or not I'm not sure. I would guess 4.0 will come along with Canonlake in late 2017 early 2018.

Pretty sure they do that also, I mean why wouldn't they. They did just that with 2.0 to 3.0, if I remember right they reduced the bandwidth overhead. I think I've also read they'll be power optimizations too.

Well the spec isn't finalized yet, and let's be honest. If latency isn't the 'big feature' they want to scream to the winds they wont, even if it's something they are working on. I doubt they can raise bandwidth without running into latency issues.

I want a PC that runs for a year off a "D" size battery and gives 10 Petaflop FP64 performance 24/7 running Milkyway@Home.
