  1. I really don't like the idea of 1 CPU being elligible for 2 different sets of globals. So the 12900K should only be in 1 category.

    Ranking CPUs by thread count would be extremely disruptive to the current ranking system however I don't feel like it's fundamentally unfair. Especially since the whole point of hyperthreading is to make a single CPU core perform more like 2. The idea behind mixed core CPUs is the same.

    I feel like the distiction between ranking by threads vs cores is basically:

    Best performace in X thread benchmark VS Best performing X core CPU

    A 7700K is one of the fastest quad core CPUs, however it isn't the fastest at 8 thread benchmarks.

     

    The current system on HWbot screws over CPUs like the 7600K, 8350K, 9600K, 9700K because they aren't "proper" 4/6/8 core CPUs. The 12900K has 16 cores so for the same reason that a 9700K is grouped with the 9900K the 12900K should be grouped with the 5950X and other 16 cores. Also if we get an 8C/16T+20C CPU in the future that's not really an issue as it would be in the 28C rankings. If it's slower than say 28C/56T or 16C/32T+12C CPUs in things like cinebench it's back to the same situation as the 9700K vs 9900K and I fail to see the problem.

    Awesome find @buildzoid  . What voltage for v.mem ?  My memory scores best ~ 2110Mhz - 2120Mhz anything more and i loose points , it seems mine does not like to go that high.

     I'm not ready to do those mods you did yet ? , but look promising , thanks for sharing.

    Stock (1.35V) Vmem. The stock cap configuration is kinda shit. Just compare the back of a 2080 Super to a 6900XT

  3. So far my exp with the 6900XT Red Devil Ultimate(XTXH core) on air is:

    Raising min clock too much tanks both FPS and stability.

    Mem clock significantly above 2150 causes performance loss. Major artifacting and black screens at 2250. (I'd guess this can clear up with more Vmem, VDDCI or VSOC depending on where in the chain the errors are coming from)

    Even with the 1.2V limit you'll want at least a 410W power limit for FSE.

    So far I've just been using a power play table with a 511W power limit based on the 6900XT OCF BIOS.
