    What I would fine most useful once the embargo is up, would be to compare the performance impact of the various Spectre and Meltdown mitigations in hardware versus software on CL-Refresh versus Coffee Lake. The software and firmware mitigations can all be disabled to do this.

    The performance impact is what I really care about. The impact of everything together mitigated in software/firmware is ~15-20%. If Intel strategically targeted the most impactful ones and dropped the perf impact to (say) 8%, that would be a really different conclusion than what I came up with looking at that list and guessing.

    I would also like to see this.

    I'm really interested in this as well.

    Also want to see this.

    Mee tooo(TM). I would also like to see the HW, vs. SW/FW, vs. unfixed, Spectre/Meltdown performance impact comparisons.

    What I would like to see a switch to enable / disable the updates if and only if it slows performance down. I have yet seem a real case that Spectre/ Meltdown stuff lead to any real security holes. And does it actually effect clients or is it only servers. When I mean enable/disable I mean a switch in bios and actually prefer it control by the OS. In normal applications it may be possible not necessary - possible in drivers.

    What is a i9-9500K, did you mean i5-9600K and if not, does that have the hardware fix for meltdown variant 3. Additionally what does CFL-R mean? Coffee Lake Refresh? if so what is the F for? same question about SKX-R.
  • Ryan Smith - Tuesday, October 9, 2018 - link

    Yes on the i5-9600K.

    Yes on CFL-R being Coffee Lake Refresh.

    SKX-R: Skylake-X Refresh

    I'm not sure where you're seeing an F though?

    He means CFL-R should really be CL-R; ditto SKX-R -> SLX-R. That is, if one follows the more standard/typical rules for acronym formation...

    Yes but with CL you are going to run into conflict with the upcoming Cannon Lake CPU’s and their eventual refreshes. Though some refer to Cannon Lake as CNL already. It’s getting weird for sure.

    I'm still sitting on the fence as long as possible before upgrading my computers until the fixes are validated and the new hardware and firmware combinations have been benchmarked sufficiently to know the impact and benefits.
