ICELAKE SP ENGINEERING SAMPLE CPU-Z VS Core i9 7980XE Skylake X
1. Maybe we've got some surprise by Intel HEDT team soon. I can't share anything much more.
However it will be products that longer LGA 2066 products too. After Gen 11 Core mainstream release. (Computex 2021 time)
2. You're right due PCIe 4.0 gen provide by CPU itself, Intel will double DMI 3.0 lane on it next gen HEDT CPU same as Rocket Lake CPU. It will working with exist PCIe 3.0 PCH like Intel 300/400 and also X299 which sharing same system PCH micro achitect.
3. Yes AVX512 clock speed from Cypress and Icelake SP had been tuning better than Skylake X/SP.
Not far from now, You'll impressive on your X299 mobo again. Happy New Year 2021 everyone. 😮
