Kinda like RAM - almost useless in terms of “upgrade” if one waits a few years. (Seems like DDR4 didn’t last long!)

That said my experience in this field is more with storage than GPU compute, but I have done some limited hacking about in the GPGPU space with that tech as well. Really fascinating stuff (and often hard to keep up with and making sure every part in the chain supports the features you want to leverage, not to mention going down the PCIe root topology rabbit hole and dealing with latency/trace-length/SnR issues with retimers vs muxers vs etc etc etc).

It's still a nascent field that's very expensive to play in, but I agree it's the future of at least part of the data infrastructure field.

Really looking forward to finally getting my hands on CXL3.x stuff (outside of a demo environment.)

for gen6, halve all numbers

how you use those today is twofold:

- Gen5 x32 via two x16 slots (this is how most people use them)

- use actually the CX8 as your PCIe switch directly to your GPUs: https://www.servethehome.com/this-is-the-nvidia-mgx-pcie-swi...

I believe only next Gen Intel and AMD Zen6 will get PCIe 6.0.

I am hoping Nvidia officially move into Server CPU market not only for their CPU but for wider Web Hosting as well. More competition for Server Hardware.

Faster lanes = more cost

More faster lanes = lots more cost

The chipset also strikes some of the balance for consumers though. It has a narrow high speed connection to the CPU but enables many lower speed devices to share that bandwidth. That way you can have your spare NVMe drive, SATA controller, wired and wireless NICs, sound hardware, most of your USB ports, your capture card, and some other random things connected over a single x4 to x8 sized channel. This leaves the high cost lanes for just the devices that actually use them (GPU and primary, possibly secondary, storage drive). I've got one consumer type Motherboard with 14 NVMe drives connected, for example, just not at full native speed directly to the CPU.

You're just SoL if you want to connect a bunch of really high bandwidth devices simultaneously (100 Gbps+ NICs, multiple GPUs at full connection speed, a dozen NVMe drives at native speed, or similar) because then you'll be paying for a workstation/server class platform which did make the "more faster lanes" tradeoff (plus some market segment gouging, of course).

Some games may be doing that. I expect that in others, the lower-resolution or missing textures are a result of the texture streaming system catastrophically failing to meet its deadline to load in the relevant textures and giving up. It's my understanding that "texture pop-in" is the too-late replacement of a low-resolution "placeholder" texture with a high-resolution texture. If the high-resolution texture doesn't load in time, then you're stuck with the low-res placeholder.

Commentary on textures that fail to load are in the "Monster Hunter: Wilds" section, starting at ~11:35 in [0], and the "Space Marine 2" section starting at ~00:14:40 in [1], which also mentions "Halo: Infinite" and "Forspoken" as other games that have the same sort of behavior. Missing textures are mentioned in the "Star Wars Jedi: Survivor" section starting at 21:21 at [1]. And -while not mentioned- if you look not-that-closely at the first ~5 seconds of that section, you can see the textures (most obviously the ground texture) go from "the same as the 16GB model" to "something you'd expect to see in a bad PS3 game".

Also in that first video, you can see some head-to-head demonstrations of the performance problems having a slower PCI-E link gives you when running out of VRAM starting at ~04:52 in the "The Last of Us Part II" section of [0] and also at ~17:00 in the "F1 25" section of that same video.

I expect there are a few other videos out there that do this sort of analysis, but I can't be arsed to find them.

802.3dj is maybe finishing up soon and has 200gbps lanes. Which is more or less about what pci-e 8.x is supposed to be. The table in the article sums both directions of a lane, which leads to confusion. People want faster ethernet in fewer lanes, so no doubt a 400gbps per lane standard will be starting up soon for pci-e to leverage as pci-e 9.

> not in a format I would normally call Ethernet

Why, because it doesn't use ether, or vampire taps?

Ethernet works over many media, and that's been pretty consistent throughout its life. It started from or at least was inspired by AlohaNet a wireless system, then you had thick and thin coax, then twisted pair and fiber, now twinax and board level interfaces are common, too.
