Processors that support 64-bit computing on Intel® architecture require an Intel 64 architecture-enabled BIOS. This means under heavy load they'll sit at TJMax which is about 95 degrees Celsius for the Ryzen 7000 series, and this will be particularly true for the 12 and 16-core models. This article compares Intel's Core i9-12900K and Core i9-12900KF desktop CPUs. We evaluated Intel's Core i9-12900K and Core i9-12900KF desktop CPUs to determine which would be better for various use cases. We shaped our testing methodology to focus on each CPU's attributes rather than relying solely on benchmarks. Intel said it was yet to remedy an issue with Denuvo on Alder Lake for 32 games, which was causing issues playing these games on the platform, but the remainder of the library was good to go.

If you're only planning to stream shows, use office apps, or browse the internet, you won't need a top-end CPU to get good performance. The most important CPU capability for general app usage is the single-core max turbo boost frequency. At some point we thought a similar thing with Horizon Zero Dawn, perhaps the 3090 Ti just wasn't capable of pushing past 200 fps, but Zen 4 proved that theory wrong reaching just over 210 fps. The 7900X matched other Zen 4 CPUs, so while impressive it was no faster than the 6-core model. We've experienced that single-core performance is essential for some games, as many don't take full advantage of multiple cores. Based on our evaluation of using Intel's Core i9-12900K CPU for professional tools, you can expect excellent tool performance with a high-performance CPU cooler.

Each P-Core has access to 1.25MB of L2 cache. From there, they're hooked up to 30MB of Intel Smart Cache, which is also shared between E-Cores and onboard integrated graphics (disabled in KF-series chips). Therein lies some of Alder Lake's magic, but there's more to getting all of these architectures working together than simply placing them all on one chip. A large part of Intel's Alder Lake performance comes from utilising these two different cores in an effective manner, and to do that it uses something called the Thread Director. Office and web applications are typically single-threaded, so running a single application won't take advantage of a many-core CPU. That's eight Efficient Cores clustered into two groups of four, each group with access to 2MB of L2 cache. These then share access to that same 30MB of Intel Smart Cache that the P-Cores are also privy to. So let's dig into it, starting with the process that defines the entire chip: Intel 7. Alder Lake is Intel's first desktop processor to use the Intel 7 process node, which was previously referred to as Intel 10nm SuperFin, and also the first in a very long time to not use the 14nm process node.

We've seen that in terms of power consumption Zen 4 isn't too impressive, typically worse off than Zen 3 when it comes to performance per watt, at least based on our recorded Blender data. The 7900X pushed total system usage to the same level as the 10900K and slightly higher than the 12700K. The most notable change of the lot for Intel Alder Lake, though, is the hybrid Core architecture. What this means is that Intel is stuffing all of the K-series 12th Gen chips, those which are arriving at launch, with two types of cores: Performance Cores (P-Cores) and Efficient Cores (E-Cores). As both a proposition to gamers today and a glimpse of what's to come from Intel, the Core i9 12900K is an incredibly exciting chip and one we've been waiting to get our hands on for a long time. It's an exciting platform, too. Often playing catch-up to AMD this past half-decade, Intel is delivering the latest technologies, such as DDR5 and PCIe 5.0, ahead of AMD this time.As was the case with the 7950X, the 7900X is a bit broken in The Riftbreaker. Realistically it would be able to match at least the 7600X, if not the 7700X, but as we saw with the 7950X this game has an issue with the dual CCD design of the 12 and 16-core models, and this is something AMD is in talks with the developer to try and solve.

As we found with the 7950X, the single thread performance of the 7900X is very strong, producing a score of 2034 pts. That's not a big improvement over the 12900K, a mere 3% difference, but it does mean the 7900X is often going to have the upper hand for productivity workloads given it's faster in Cinebench R23 for both multi and single core performance. The 7900X looks a bit more competitive from a value perspective in Premiere Pro, costing just 9% more than the 7700X when looking at price to performance. It's also much better value than the competing Intel parts. That said, if performance is the ultimate goal then paying the premium for the 7950X will be worth it. What We Learned The Core i9 12900K represents the very best in Intel's desktop 12th Generation processors, and what that means is it houses the Alder Lake architecture in its most performant form. At its simplest, that equates to more cores, more speed, and more bandwidth than ever before, but if you dig beneath the surface you'll find a chip architecture that is wildly different to what came before. CONCLUSION : Intel have adequate number of cores most program (including serious games) can use at max but AMD has so many cores that a program rarely or doesn't use all of the cores ( unless you are doing 3D rendering and blending stuff which would benefit from more cores ) and we know that Intel has far better cores than AMD , so for me the Winner is Intel . FINALLY IF YOU'RE READY TO SPEND SOME MONEY ON A GREAT COOLING SYSTEM FOR YOUR PC THEN THIS CPU IS A BIG YES FOR ME ! Let's not forget what the Core i9 12900K is up against. That's the Ryzen 9 5950X, potentially the best processor AMD has ever put together and the most well-suited desktop CPU for just about anything you throw at it. Not to put down the Ryzen 9 5950X in any way, but the Core i9 12900K is simply the far better gaming chip.When compared to the 5900X, the 7900X was 24% faster in this test but also pushed system consumption 47% higher, meaning it's much worse when it comes to performance per watt. That said, it was faster than both the 12700K and 12900K, quite a bit faster, and used a bit less power than the 12900K, so at least relative to Intel it's a win for AMD. Cooling Performance

Trust me your are never gonna lose if you're choosing AMD or Intel , but to choose one , here is some tip :- The 7900X is able to outperform the 12900K by a 12% margin and put away the old 5900X by a convincing 25% margin. Based on our evaluation of using Intel's Core i9-12900KF CPU for gaming, you can expect excellent game performance with a high-performance CPU cooler. With the right motherboard and the correct memory modules, it can now support faster memory speeds of up to DDR5-8266 MHz.And you're probably already thinking that's a lot of architectural codenames, and you'd be right. Alder Lake is like a Russian nesting doll of architectures. It doesn't get any easier, either, but it is quite a bit more exciting for it. We found that, in general, more cores do provide better performance in professional tools and when running multiple applications simultaneously.
