pcie5 PCI Express 5

[Alder Lake]

I heard that intel 12th gen is coming soon, and that with it will come DDR5 and PCIE gen 5, I've heard lots of news about 12900k, like hitting 5.2, or even 5.3GhZ on all 8 performance cores, and about DDR5 hitting insane things like 6400MT/s, while needing improvement in timings to beat DDR4, but what's happening with PCIE gen 5? I haven't really heard anything about it yet

Doubling of the speed/bandwidth, as 4 was over 3 was over 2, etc.  Nothing special.

no downsides?

As with PCIe 4.0 upon launch for AMD, I'm sure the 1st gen PCIe 5.0 chipset for Intel will also require active cooling; if at all. Or, it could remain at PCIe 4.0 as well.

Basically, PCIe 5.0 would be for the GPU and probably the first M.2 slot. Being that there's not much of a difference between PCIe 3.0 and 4.0 for GPUs, that leaves NVMe storage (Direct Storage) as the only practical use-case for desktop use; at least for now.

I mean I don't consider that a problem? That's just first iteration of a technology and refinements will make it more efficient down the line.

It is and isn't related at the same time, but doubling the performance of PCIe without doubling the efficiency of the chipset will require active cooling.

 

After building my last AMD X570 platform, I vow to never *ever* build a rig where the chipset requires active cooling. The fans have a short life and, well, good luck trying to source a replacement for something proprietary (ASRock, I'm looking at you!)

PCIe 5.0 is actually about I/O more than anything. Higher bandwidth ports and more of them. PCIe 4.0 is mostly useless for GPUs and storage is already faster than the majority of applications can make use of. The biggest benefit for GPUs/storage is simply going to be the ability to bifurcate the lanes, so you can install more GPUs/M.2 drives and still get PCIe 4.0 bandwidth with half the lanes.

as they said, seems to be ~2x faster, and unlike RAM, has pretty much no downsides
