Leaked Intel i9-12900K Benchmark Shows Gains Over the Ryzen 5950X (digitaltrends.com) 90

Posted by BeauHD from the what-to-expect dept.
UnknowingFool writes: An engineering sample of Intel's next flagship processor, the i9-12900K, was shown to beat AMD's current flagship 5950X in Cinebench R20 by 18% in multi-core and 28% in single-core tests. The next generation of Intel processors is believed to use a hybrid big.LITTLE design where 8 of its 16 cores are for low power usage and 8 are for full power. The low power cores only run in single thread where the high power cores can run 2 threads. No official word on pricing or release date from Intel though but engineering samples and B600 motherboards are being sold in China for $1,250 and $1,150, respectively. According to leaker OneRaichu, the results for the 12900K were gathered using water-cooling and without overclocking, so it's possible the final score could be even higher. The rumors suggest the processor will come with 16 cores and 24 threads with a boost clock speed of up to 5.3GHz.

      Really depends on the system it's in. These days CPUs throttle when they get too hot, and a lot of systems do throttle. Laptops are particularly bad (the Intel Macbooks were notorious for it) but even desktops from big names like Alienware often throttle because of really bad cooling setups.

      GPUs are the same, there is a theoretical maximum performance and then there is what any given system is capable of due to thermal constraints.

        And they also mention it is not overclocked and that power requirements are about the same, or a little bit less, then the current i9.

Even though most new games take advantage of multiple cores, they can still end up CPU bound on single core performance if they are single threading specific functions or are only using a handful of threads for everything so they are not using all of the available cores. I have a 18c/36t CPU and it gets CPU bound on some games compared to my older 4790K system. You can see them maxing out a few of the cores while the rest are all sitting near idle.

              Indeed. For years, the venerable 4790K was the single-threaded top dog. I don't think Intel came out with anything faster per core until either the 7700K or 8700K, and even then it was a tiny marginal improvement -- certainly not 20%. That was a disappointing stretch in terms of CPU innovation -- we are fortunate that AMD is finally making Intel get off their ass and do something!

    This is manufactured on Intel's 10 nm process, with a density of 100.8 million transistors per mm^2. That's competitive with TSMC's 7FF process that AMD is currently using (96.5 MT/mm^2). So this is a pretty apples-to-apples comparison of Alder Lake vs Zen 3. And falls in line with my theory that there's really not much speed/power difference between the different companies' architectures, and most of the performance differences we're seeing are due to manufacturing process size. Intel's 14nm process was 37.5 MT/mm^2, which was a massive disadvantage.

    AMD opted not to pay for TSMC's 5nm process (173 MT/mm^2) for Zen 3, which is what Apple's processors are being manufactured on. That's a big enough gap with Intel's 10nm that AMD probably could've left Intel in the dust had they chosen to pay TSMC more (Apple is only expected to take half of TSMC's 5nm capacity this year). Likewise, Intel could leapfrog AMD and possibly even Apple by paying TSMC to use their 5nm process. (And if you want more fun things to think about, TSMC's 3nm process is supposed to be about 250 MT/mm^2, Intel's 7nm process is estimated to come in between 200-250 MT/mm^2.)

    If you go back the last 30 years, you see that Intel always had an advantage in manufacturing process density. It wasn't that their processors were better. They simply could build them smaller (and thus faster and using less power). Up until a few years ago when they stumbled and ran into problems rolling out their 10nm process.

The Ryzen 6000 series using Zen 4 will be fabricated on TSMC 5nm and likely regain the top position for that reason alone, but there will certainly be some architectural improvements as well if that weren’t enough for whatever reason.

It also doesn’t have a company (Apple) that probably makes more revenue in certain weeks than AMD does all year bidding against them for those limited wafers either.
