    Better served getting a 10-series chip whilst you can.

    That power draw as well lol.

    for all intents it seems to be the same card minus some gays name on it and a shielded cover ? with OEM added to it - GoNz0.

    Wasn't expecting a general regression in performance (Am i read it right?).

    TBH,I would probably give some time for BIOS and Windows updates. It was the same with Ryzen at the start,and this is after all a new core,with some big changes.

    Looks like a rushed backport to have something to counter Zen 3. Firmware/software voodoo might help, but ultimately it needs a revision or two (that won't happen because they'll just shift attention to Alder Lake).

    Not disaggreing but I would imagine that rushed in this case means they started 12 or 18 months ago. Leading edge designs (or in case of Intel currently, almost leading edge) just take ages from start to finish.

    AMD and Intel kinda believe each other's performance targets, e.g. Zen 2 was designed to compete with 10nm Ice Lake IIRC, because AMD assumed it would be ready by the time of Zen 2 launch.

    Still on 14nm. Power consumption a joke. Calling the i9-11900K an actual 'i9' when it's just a speed bump.

    Some of the benchmarks look off,ie,the new generation loosing to the previous ones,so something does look a bit wonky. One thing that has changed though is the cache hierachy:

    The L1D regresses from 4 cycles to 5 cycles with its 50% capacity increase to 48KB, the L2 regresses 1 cycle from 12 to 13 cycles as it doubles in capacity, while the L3 surprisingly enough sees a larger estimated 7.5 cycle regression.

    The L3 regression is a bit puzzling, as it does differ from the measurements and disclosures Intel had with Sunny Cove in Ice Lake, and more closely matches the latency regressions we saw with the Willow Cove core in Tiger Lake. However as far as we can tell, the set-associativity is still 16-way here, and obviously enough the cache size also remained the same at 16MB. I’m not seeing any bandwidth changes in the new design either. Maybe Intel will comment in the full review about what’s happening here.

    This reminds me of AMD's Brisbane Athlon X2 (the 65nm die shrink) that had slower caches: AMD simply bumped clocks by 100-200MHz on some models to solve the problem. They never disclosed what happened and I doubt Intel will.

    EDIT: it turns out they did. It's been a while.

    I'm feeling a distinct lack of buyers remorse on the Comet lake i5 10400f and other bits I've ordered last week.

    Hardwareluxx published a review with an updated BIOS: https://www.hardwareluxx.de/index.ph...orab-test.html

    CB20 regressed, Y-Cruncher improved by 36% (it's an AVX-512 workload, so maybe the mobo was holding it back), gaming improvements are negligible. Even if further BIOS updates bring 5% more performance that won't be enough to save it, and it will obviously not be consistent across all workloads.

    If I were Intel I'd anticipate the launch and sell those quickly before Ryzen gets back in stock everywhere.

    I'd like to see them overclock the uncore frequency to ~5ghz on both the 10700K and 11700K, to see how they compare. According to an article on the chipsandcheese website, the current microcode might be causing the uncore frequency to dip too low. This can affect both the L3 cache and RAM latency.

    Does anyone know what the load temps are like on the 11700k? Have Intel beefed up the stock cooler on the 11700 /11700F?
