    "The i7-11700K holds 8-cores/16-threads seem to be being behind the AMD Ryzen 7 5800X" If Intel keeps current prices then I would compare it with a R5 5600X since its more expensive than i7 10700K at the moment at least where I live 346 EUR for the i7 vs 372 EUR for the R5 at the same store.

    More power and less heat? - interesting...
    If they can produce enough of these since AMD has problems with stocks - especially high end - right now it could be a winner...

    The problem is that it doesn’t seem to be much better than the 10700F (except in DoW3 a Handbrake, but who knows how representative those scores are). It feels like Rocket Lake was a massive waste of engineering resources. I bet Intel gained very little from backporting Ice Lake that they can use in the future. They could have cut the price of Comet Lake (and maybe add PCIE4 support) and call it a day.

    i suppose those power/temp difference can be attributed to 14nm vs 7nm.

    The fact that it uses more power than 5800X yes but the fact that ran 18 degrees cooler it is strange...- it is way too much of a difference...maybe an temp measurement error?

    No. That is impossible. Power is proportional with heat.

    Don't confuse heat with temperature.
    Temperature is a measure for hot/cold. It's an intensive property, meaning its independent of the system size.
    Heat is type of energy. Extensive property.

    It means that intel's system is able to dissipate heat faster than AMD. And not just faster, but more faster than it's power is bigger.
    14nm = bigger die area = better heat dissipation

    Think of it like Intel having lower heat per area than AMD

    Lookin good. If the price is right then it's a insta buy, otherwise I'll wait a bit, atm this i5 10500 still is plenty.

    idk if an error in measurement but where, i think amd's sensors are the hottest spot and intel's is on the edge.

    i really would like to see speed/voltages under load and ofc more data points - it is early.

    Exacly , Rocket will have big cores , so temperature wise it can be quite good , so everyone will have 5.2-5.3 Ghz out of box. Expect 0 OC potential as silicon will be maxed in normal operating temps.

    Other than intel having a bigger area do not forget last gen they lapped their cpus practically, so that might be helping too. Now if that cones out close to 5600x price say 350 it will become the value king except if amd respond with a 5700 and drop 50usd on the 5600x price ..... But first they will have to get better stock.

    Nice, in some games it's fastest than what AMD have to offers :)
    With high frequency RAM it will beat AMD easily, at least in games.

    Possibly the heat spreader has tighter tolerances than will be seen on the production unit

    Not too unusual if Intel is lapping their dies again. They've done this before with surprisingly good results on thermals.

    Performance in games is very zen3 like with disappointing multicore performance. Meh.

    5800X is the absolute gaming CPU for 2020-2022.

    Shame its so overpriced. 100$ less and it would be cpu to get. Maybe intel can force prices down little bit. ;)

    I rather go with 5600X and get better GPU ( if you can get one ) :)
