    Some people are skeptical because Intel have been promising these kinds of moderate gains with every iteration the last couple of years and missing the mark. The lack of gaming benchmark leaks doesn't help either.

    While these numbers are impressive when compared to Rocket Lake, they are nowhere near what Conroe brought to the table. This improvement is believable. With Conroe, the jump was unprecedented at the time. People could be excused for being in denial and in a state of disbelief back then. I don't think anyone is in that frame of mind now. There's really nothing to be in denial about. This isn't a knockout blow to anyone. If accurate however, this may be a much welcome sign of Intel finally getting back on track.

    Actually intel's engineering people have been working the whole time, but the delays of 10nm + poor management desicions have lead to the lack of actual products, Reminder that icelake was intended to launch in 2016, the design had been complete , but 10 nm was so bad, that we didn't see it in any products until 2019 h2.

    sapphire rapids is the first product that intel will have launched in quite some time(>6 years?) that hasn't been horrifically delayed or cobbled together last minute.

    Delay was due to lack of competition nothing else. Better and easier to cream money with current tech , why overinvest when you are only player on the market.

    More like Intel competed with Intel internally as their CEOs tried to grab power and getting fired one after the next. Rocket Lake was the worst execution of a product launch I had ever seen LMAO.

    the delay of 10nm has nothing to do with competition in this case , It has been the cause of potentially billion dollar losses , whether amd was there or not. nothing will recover the R&D costs of canonlake and the late entry of icelake means that intel will likely not fully recover those costs either, even if there was no market pressure at the time they were supposed to launch (2012-2016), intel had already invested in those before bulldozer launched, thats how far in advance these things are planned. it takes >5 years to design a new process node and build or upgrade a fab to manufacture chips in volume on that new node.

    What I see isn't much crazier than Zen3 + duct tape cache on, so it's a great step from Intel, but I think them being behind on process still hurts them.

    I actually like the idea of the efficiency cores on the geek level, but on the other hand they're just an admission of an inflexible or restricted design.

    Once DDR5 is at least at a mainstream 6400 without crazy high latencies, I think it would be the best time to review CPUs from Intel or AMD again.

    i don't think it fair to call it duct tape cache, the architecture designed with the capability but left unused.

    True but at the same time look what happend after ryzen ... how much pressure there is on Intel . After few boring generations i think now we will see nice jump im performance / $ department :) - which all can enjoy. I'm prettty sure ryzen pricess will fall from the moon ( on which they station now ).

    I just love how they don't start the scale at 0, but close to the top range, to make it significant.

    What game? Ah, nevermind, Ashes of the Singularity. Well, if you dig through the benchmarks, there are far better 5950X scores with these settings. This one seems unusually low. Still, certainly impressive.

    Edit: Christ, I can't seem to read benchmark data today. I looked at a 3090 result rather than a 3080 for the 5950X. In that context this is even more impressive. I might actually upgrade in Q4 2022 after all.

    Well this really looks like another Conroe for Intel. But let's not jump to conclusions just yet. AMD is not the same company it was 15 years ago. They might actually have an answer to it this time around. Or at least I hope they have...

    btw. That would be an interesting upgrade going from the legendary 2700K to 12700K :)

    Conroe was literally double performance at half the price. This is ~40% at the same price. Not quite there yet I'm afraid, but come late next year, we'll have both an indirect and a direct AMD response and an Intel refresh. I'm salivating at the thought.

    So that's intel's "Zen" moment...

    Looks really impressive but unlike 2006 i think AMD will be prepared this time as they might have other tricks before Zen 4.

    i did try to point this out in the icelake thread,

    the 11000 series was just a stepping stone to get intels new cache and pipeline out into the wild.

    the increments of skylake to comit lake have been tiny, underreaching changes that meant little without the major changes (now in alders lake) because without 10nm going all in was not going to happen,

    Rocket had one of the biggest of those tiny changes diverging from icelake with its l1 cache down to 3 cycles from 5 but being on 14nm restrained its full design intended implementation.

    You lost some cores true, but these 10 cores were not design optimal for intel ringbus.

    Word is that Alderlake is 7nm btw, not 10nm as previously thought.

    I'm probably gonna stick with my 5800X until the next console generation (probably 2025 or 2026 I guess) so whatever Intel or AMD have out by then should be a real monster. Maybe at least 3-4x the single thread performance I get now.

    If all this ends up to be real, then the bigger pity is that the CPU is not made with a proper process and it needs the "low power" cores to basically hide the power design deficits. This thing should have been a real 16-core.

    I was thinking 12 P-cores + 4 E-cores would be a better combo, 4Ecores/4threads is plenty for office workload and 12 Pcores/24threads would make it better gaming CPU than 10900K

    seems like 330eur will be the standard launch retail price for the midrangers since 5600X.
    5600X was very highly demanded despite launching the price of prev gen Ryzen 7
    4 extra small cores are of very little consolation to me,though I am a huge fan of energy efficient designs for desktop work.
    if this beats 5800X in gaming just like 5600X beat 9700K people will line up,despite the fact it's a six core

    [​IMG]

    anyone with an octa-core from r7 3000/intel i7 running at least 3600MHz ram series should not care about upgrading until late ddr5,or at least not bother with it because of lackluster performance.
    people who stayed on ryzen 1st/2nd gen or an older gen six core like 8700K w.3000mhz ram will need to upgrade in early ddr5 days,which will mean lower performance at inflated costs of memory and boards.

    They seem to have a huge power deficit vs AMD, which I would say leaves AMD a lot of playroom.
