Somewhat surprised at the lack of PCIe 4.0. Is there really no demand for more PCI bandwidth on high-end desktops?

- Tenoke 6y agoPCIe 4.0 is likely to be short lived given that PCIe 5.0 seems to be around the corner. On the AMD side where they already have 4.0, few care for it (I do though - just ordered a mobo and processor that use it) - 4.0 nvmes aren't faster for common use cases, and it mostly matters when going multi-gpu which is only seen in some professional use (and even then you can use a threadripper and just have a lot of 3.0 lanes). Then next ~year ryzen 5000 which will require a new socket seems likely to already support 5.0. I'm guessing Intel will just altogether skip 4.0.
- kllrnohj 6y agoThere is, but keep in mind this is yet another refresh of Skylake, not really a "new" CPU. Supposedly the new socket is PCI-E 4.0 capable, which the next CPU "Rocket Lake" will supposedly enable. But since it's still 16 lanes from the CPU only, that means you'll only get PCI-E 4.0 to likely a single slot. And likely not any of the M.2 drives, which typically are connected to the chipset instead.
- yxhuvud 6y agoOdds are that is coupled to either CPU architecture or mobo standard, and they didnt touch either. You should go AMD if you want PCIe4 currently. Which is a bit funny as Intel sells certain peripherals that supports it.
