Compensation for Spectra and Meltdown issue in i7 CPUs

[IRoth]

Hello!

How is INTEL planning to compensate customers for the expected performance degradation caused by CPU microcode patches to fix the security issues Spectre and Meltdown ?

PS C:\WINDOWS\system32> Get-SpeculationControlSettings

Speculation control settings for CVE-2017-5715 [branch target injection]

Hardware support for branch target injection mitigation is present: False

Windows OS support for branch target injection mitigation is present: True

Windows OS support for branch target injection mitigation is enabled: False

Windows OS support for branch target injection mitigation is disabled by system policy: False

Windows OS support for branch target injection mitigation is disabled by absence of hardware support: True

Speculation control settings for CVE-2017-5754 [rogue data cache load]

Hardware requires kernel VA shadowing: True

Windows OS support for kernel VA shadow is present: True

Windows OS support for kernel VA shadow is enabled: True
