IFA 2018 | Intel launches Whiskey Lake-U and Amber Lake-Y CPUs with focus on enhanced mobile connectivity
https://www.notebookcheck.net/Intel-launches-Whiskey-Lake-U-and-Amber-Lake-Y-CPUs-with-focus-on-enhanced-mobile-connectivity.325710.0.html
Update 8/29 - We reached out to Intel to understand whether Spectre/Meltdown mitigation has been incorporated at the hardware level in the new CPUs and this is what they had to say -

Laptops powered by the new performance mobile 8th Gen Intel Core processors announced today are expected to ship from OEM and system manufacturers
with protections for the security vulnerabilities commonly referred to as "Spectre", "Meltdown” and “L1TF”.
These protections include a combination of the HW design changes we announced earlier this year as well as software and microcode updates.

やはりシリコンレベルで対策済みであり、ハードウェアでの緩和策は有効である
ちなみにSpectre Variant2のみマイクロコード+OSで引き続き対応だが、V1/V3/L1TFはシリコンで対応済みっぽい

ここの人達はwhiskeyとamberに関心はないと思われるが、これらのCPUに緩和策が施されるという事は、coffee refreshにも緩和策が期待できると言うことでもある

So I just got word from Intel. SOME of the Smeltdown mitigations in hardware are in WHL/AML,
though I'm waiting to hear which ones and on which parts. I've also seen unconfirmed that WHL and AML are on different 14 sub-nodes. Stay tuned.

Clarification from @intel on Whiskey Lake mitigations: Meltdown mitigations in hardware, L1TF in hardware.
V2 is still software/microcode. Cascade Lake will have V2 protection in hardware.

Intelが大げさにアピールしないから特に何もしなかったと思ってたけどそんなことなかった
特にやばくて直しやすいやつだけ修正した感じか
デスクトップの9000番台も同じっぽいな
