    Metldown and Spectre

    Surprised nobody's talking about this...

    Or am I just being blind and there's already 5 pages on it (search turned up nothing)?

    so after being know about for nearly a year, and being public knowledge for 2(?) months intel have a fix for one cpu family ready....

    i was hearing rumours that these are the oldest cpu likely to get the fix and that intel will rely on mobo makers to sort out the 90 series boards and older

    To make matters worse, it seems intel borked the microcode update...

    seems to particularly affect Haswell, Broadwell, Skylake and Kabylake...

    patches have been playing hell with my system since fall creators. Things are mostly fine for me, and the latest AGESA update for the BIOS has made things fly. Loving Ryzen <3

    Might not be it, but... Check your audio devices... After the update windows had somehow duplicated some of mine, and the enhancements were going screwy. Had to uninstall the originals and the duplicates, then reinstall the originals. Didn't have to mess with the devices that didn't duplicate...

    I don't think i'll see any real world difference in my 6600k after the fix, would like a new GFX card at some point though.

    Haha same. I'm looking for an excuse to retire my 3930K system and build a shiny new rig.

    Okay guys to be fully 100% protected, bios needs a microcode update as well to prevent spectre as well as windows update to protect against meltdown. With both bios an windows update, their's significant hit to ssd performance, even on newer 8700k chips too.

    Moving on we find some even more extreme results when testing with CrystalDiskMark. The sequential read and write performance all looks okay. Then we get to the 512K write test and whatís gone wrong here, a 41% reduction in performance can be see and this wasnít a once off deal. I ran this test dozens of times after multiple resets to try and work out if it was just some kind of glitch. Unfortunately this is the figure I kept receiving. Interestingly the 512K read performance itís nearly as heavily impacted, just an 8% reduction, though thatís still certainly very noteworthy reduction.

    Appears be about 2-3% on newer cpu's, assuming older ones be closer to the 30% mark quoted by Intel.

    In short there's not a lot we can do other than keep stuff up to date... and in doing so we may lose some performance.

    Slightly concerned about my Ivy Bridge build as "older" cpus are said to suffer most from performance loss.

    i think that explains it as clear as anything i have seen.

    it is going to hurt intel perf most....
