[SOLVED] Why 10th Gen Intel mobile CPUs still have PCIe 3.0?

[rvidd]

AMD already started making PCIe 4.0 CPUs and motherboards. But the very new Intel 10th Gen mobile CPUs still have PCIe 3.0 lanes. Is there any reason why Intel is not making PCIe 4.0 CPUs?

Does Intel plan to skip PCIe 4.0 since PCIe 5.0 release is close?

Laptops, in general are thermally limited. PCIe 4.0 would not provide any significant benefit. PCIe 4.0 probably won't provide significant real-world benefits for desktops today. Sure, there will be NVMe SSDs that benchmark with huge numbers. But there will be little improvements in day-to-day usage for people that buy them.

Laptops don't have enough expandability to make use of PCIe4.0. I'd be curious to know how few laptops even expose any PCIe3.0 lanes to anything (including dGPU)

since PCIe 5.0 release is close

I expect 18 months for desktop, 2 years on laptop for PCIe 5.0.
2021 at the earliest.
