    Anandtech have just posted up an update with a new microcode revision, small improvements overall (1-3%), latencies improve but AVX512 performance drops (along with peak power) due to a new 200MHz AVX offset. 5800X still leads in the majority of tests, but certainly less instances of regression from the 10700K.

    Their original review has also been updated.

    Toms Hardware has a delidded 11700K to estimate the die size. Estimated to be ~290mm2, so very large for a consumer (not prosumer) part. 5000 series Ryzen is 83mm2 (1 CCX) plus a ~125mm2 12nm IO controller

    Comparing to 8th/9th and 10th gen die size (from der8auer) with the 11700K scaled by an amateur (me) using MS paint:

    CPUs-5-1024x576.jpg

    Very slightly longer, much wider. Looking further back in time, 7700K was a tiny 122mm2 also on 14nm. Crazy to think they sold those for ~$AU350-370, whereas that is now 10600K money (which used a 206mm2 die also on 14nm). Profit margin on KabyLake must have been insane.

    The new microcode introduces a 200MHz clock-offset, so power consumption has dropped, but so has performance for AVX-512 loads. Still can't understand why Intel included AVX-512 when Alderlake will not support it, how is that going to encourage AVX-512 adoption amongst developers?

    Like mining with a bunch of gpu or playing game with an 11gen, it would a similar power draw.

    CPU Preorders at PLE and MWAVE so far, maybe others.
    Just woke up and saw a tweet from PLE

    You right, I was hoping the price would be more reasonable but kind of expected prices to be high.

    Looks like PCCG has pre orders live now so I assume most retailers will have them up today.

    I am kind of surprised they are even taking pre orders at all

    You can pre-order 11th Gen from Scorptec and other retailers right now if you want to book one for yourself.

    https://www.mwave.com.au/cpu-processors/intel-desktop-cpu?display=list&filteroptions=53271%3D11th-gen&filter=53271%3Dgeneration

    https://www.scorptec.com.au/product/cpu/intel-1200-11th-gen

    https://www.ple.com.au/Products/645381/Intel-Core-i9-11900K-35GHz-Rocket-Lake-8-Core-16-Thread-LGA1200---No-HSF-Retail-Box

    They have the 11400 all the way to 11900K to pre-order.

    11400 – $289
    11400f – $249
    11600 – $359
    11600kf – $379
    11700 – $529
    11700K – $649
    11900 – $709
    11900K – $889

    11900K already sold out on PCCG, after my 3080 SNAFU I think I'll just wait for umart to get stock and save myself the heartache.

    PS got a new PC case sitting in the living room with everything installed already except the CPU. Ready to go lol

    ^ Runout deals on the 10xxx processors have started it seems. The 10600kf is now $269 @msy link (listed as in stock at the time of the post).

    Is there any reason to get a 11900K over a 11700K? as it doesn't seem to be that much faster at about 5%. I will be cooling it with a Corsair A500 tower cooler but I get the impression that if the 11900K turbo-boosts and overclocks on all cores even that won't be able to keep it cool and the only thing that will do it is water so if it's going to thermally throttle then that won't be of much advantage.

    There's also the possibility to consider that if say all the cores on both CPU's are doing 3 Ghz then the 11900K is binned better and will be using less power than the 11700K doing the same amount of work but how much less is anyone's guess. I'll probably also get the "KF" variant as well.
