While AMD just recently implemented PCIe Gen 4.0 on the latest motherboards and graphics cards, we've already seen some PCIe Gen 5 announcements. As it seems, Intel is already working on some PCIe Ge... Intel server platform going for Socket LGA4677 with PCIe 5.0 and DDR5 memory
Well having 4.0 with AMD is better than waiting a year for Intel's work in progress 5.0 AMD will have 5.0 on Ryzen 4.
Rumors have been around for a long time that PCIe 4.0 would be very short lived and Intel might even consider skipping it, or if anything not push too hard for it, but push for PCIe 5 instead. Suppose these got a bit more substance now.
Honestly... nice for professional fields. As a gamer, those technologies are more or less irrelevant at the moment. Even PCIe 4.0 is for 90% of all scenarios, imho.
Who might have thought Intel will be skiping PCIe 4.0 - they were making very vague and inconclusive statements, something about accelerating the adoption of PCIe 5.0 and 6.0, but nothing about PCIe 4.0! Now we need more jokes about needing PCIe 7.0 ludicrous speed.
Not that the average user will ever need PCIe Gen5 anytime soon (or Gen4), having faster lanes means you can have cheaper to manufacture products using less lanes. Imagine your high end GPU only using 4 PCIe Gen5 lanes, reserving the rest for other components.
Good luck.....!! HAHAHAHAHA. Nothing will even support the aforementioned PCI-e 5.0 for quite some time, so again..... Good luck there Intel. Especially with that 3 billion dollars set aside to attempt to gain your throne back.....
And yet Ice Lake SP with Socket 4189 (to be released in 2020) might get PCIe 4.0 with the Whitley platform. https://wccftech.com/intel-xeon-sapphire-rapids-granite-rapids-cpus-lga-4677-compatible-ddr5-pcie-5/
Although I don't see consumer hardware needing PCI-e 5.0 for quite some time, we're already nearing the maximum throughput for PCI-e 4.0 on the server Ethernet networking front. 400Gbps is currently in development (that's 50GBps) which utilizes most of the bandwidth available to a PCI-e 4.0 x16 slot. If data centers continue to fund switch makers as they have been for the past decade, I expect we'll see 800Gbps+ networking coming out shortly after PCI-e 5.0 hardware is released which would consume most of the available bandwidth in a PCI-e 5.0 x16 slot. That reminds me, with 200Gbps Ethernet available on the market, it's sad the average consumer is still stuck with 1Gbps Ethernet. Back on topic though, keep in mind this article is about server hardware. I wouldn't be surprised if consumers get PCI-e 5.0 after servers already have it.
Etherner over twisted pair is limited to 25G/40G. 2.5GBASE-T and 5GBASE-T Ethernet reach 100 m with Cat 5E/6 cables, 10GBASE-T requires Cat.6A to reach 100 m, and 25GBASE-T and 40GBASE-T require Cat.8 cabling and only work up to 30 m. There are recent 'gamer' X570 motherboards which use 2.5GBASE-T or 10GBASE-T Ethernet controllers from Realtek and Marvell/Aquantia; I believe Intel prepares 2.5GBASE-T products as well. But there aren't many 2.5G/5G/10GBASE-T switches/routers, not to mention internet providers that offer >1 GBit/s. Intel's adoption cadence has always been quite fast - if PCIe 5.0 comes to Server/HPC by 2021, it shall trickle down to workstation/desktop by 2022; AMD's Ryzen will probably have it too by then.
I'm fine with 2.5G Ethernet over twisted pair; unfortunately there are only a few home Wi-Fi routers capable of 2.5G, and they are crazily priced: $400 ASUS ROG Rapture GT-AX11000 and $300 TP-Link Archer AX6000A. There's a forthcoming $150 Keenetic Titan with 2.5G WAN ports, but it won't be available in Europe or America.
