Intel and PCIe 4.0 and other thoughts and contradictions

[Turtle Rig]

So I was wondering why Intel is not going PCIe 4.0 even with the fact there are new X299 mobos for their upcoming HEDT chips.  This statement by them threw me off.  So PCIe 4.0 is pointless compared to PCIe 3.0 as they said in as nice way.  Then couple weeks later you see intel talking about PCIe 6.0 lol in 2021 specs revealed.  They also talk about PCIe 5.0.  So first 4.0 is same as 3.0 then they don't compete with AMD and their new tech PCIe 4.0 etc etc.  Intel will say and do anything to prove to the world their 1080XE is king over Ryzen 16 core coming up.  Yet AMD brings new technology Intel also brings new tech with the revised x299, just not PCIe 4.0   The x299 boards just have some advancements and tweaks and some new tech but once again no PCIe 4.0 asa according to them its not faster then PCIe 4.0. So if someone buys the Intel HEDT in a year or so when new nVidia video card comes out it will be PCIe 4.0 right ?  So if I got the x299 I would be in a deep hole.  Not to mention PCIe 5.0 will come out eventually.  Basically your staying behind with Intel and your forced to do a full upgrade to get PCIe 4.0 or PCIe 5.0 for that matter.  Unless nVidias next chip is PCIe 3.0 I think buying a x299 is a very risky as your stuck on PCIe 3.0 until another upgrade.  But you just spent 1k on a CPU and 500 on a motherboard and 400 on RAM.  All that goes to waste when nVidias new video card supporting PCIe 4.0 comes out.  Also you cant use PCIe 4.0 SSD cards.  ThreadRipper will have the new tech and bunch of PCIe lanes but the single core performance is gonna be shakey as you cant have 32 cores running at 4.4Ghz or something.  They would need to run at 3.9Ghz to 4.3Ghz.  Also the recent 1080XE benchies show them falling behind sorta.  But the douches that did the review had the Intel clock to 3Ghz stock on all cores.  Now imagine 4.6Ghz all cores the 18 core 1080XE will crush the 24 core TR let alone the 3950x or am I wrong ?

i consider pcie4 to be a negative atm as long as it requires that little fan, it was the first thing to break in my z77 board, amd definitely jumped the gun on that unless someone REALLY wants a pcie4 nvme ssd badly.if we can figure out some passive cooling solution (cost doesn't really much too much), then pcie4 would be a positive.

You're not running all cores at 4.6GHz unless you put some serious voltage through it and drawing over twice the power of the AMD chip. And it was running 3GHz because that's how Turbo Boost works, 4.6GHz on a one thread load, 4.5GHz on a two thread load and so on and so forth.

The specs for PCIe4.0 has been around since 2017. PCIe3.0 has only recently seen full bandwidth saturation with the advent of NVMe storage. PCIe5.0 was finalized earlier this year, so any chips that were either early enough in development, or starting after that spec was finalized can safely integrate it without changes rendering any previous work obsolete. PCIe6.0 is still having specs sorted, and won't be finalized until 2021 (expected, not guaranteed), so it hardware likely won't even start to implement it until 2022 at the earliest.

 

Intel won't fight AMD this round because they plain were not prepared for AMD to hit the market like they did. They will obviously spin it to make it sound like it's not worth it, or whatever, but at that point, it's just marketing to put on the best face.

I am very confused about what is being said in this bit. But more cores = less speed. There's science at fault here, no conspiracy.

Intel has problems with their factories, they can't make big processors at 10nm or lower. So they're stuck with 14nm for the moment.

It would be an expensive investment to modify current processors to support pci-e 4.0, it's not as easy as changing some software, they have to modify silicon, wait a few months for test processors to be made, validate them, do microcode, bios patches, then run mass production...

Changes are they may have to modify the pinout of the processors, which would mean another socket and people are already too confused and pissed.

Also pci-e 4.0 is more power hungry, you'll add 10-20w to the TDP... also you have problems with maximum length of pci-e 4.0 traces on existing motherboards...

 

It makes more sense to wait for pci-e 5 and DDR5 and do them both together when they have to change the socket anyway for DDR5

Well, Gigabyte has a solution, if you're ok wtih a 700$ AM4 motherboard
