Intel Core i9-12900K processor leak suggests it could be a Ryzen 5950X killer

Intels Core i9-12900K has been spotted in yet more Alder Lake leaks, with another benchmark flipped suggesting that well get some promising performance from the 12th gen flagship.

This comes from the Twitter-based hardware leaker HXL (again) which reported a few purported benchmarks on Bilibili, showing the 12900K put to the test on Cinebench R20 and CPU-Z.

As observed, testing was performed on Windows 11 with DDR4 system RAM, using a QS or qualifying sample (meaning this is the final pre-release release and should be running low). nearly identical to the commercial chip).

In Cinebench R20, the single-threaded performance of the Core i9-12900K was found to be almost 20% faster than the 11900K, and the same story was true in CPU-Z (in fact, the 12900K here was 21% faster).

When multithreaded with Cinebench, the 12900K was 65% faster than the 11900K, and just slightly faster than the AMD Ryzen 9 5950X. With CPU-Z, Alder Lake’s flagship was 75% better than the 11900K, and very close to the 5950X (the AMD chip was 3% faster here, so only had the marginal advantage).


Analysis: once again revealing performances

We must, of course, apply the usual caveats and caution about leaked benchmarks, but this is another promising set of leaked results for Alder Lake. This single-core performance beating the current-gen Rocket Lake by 20% on two benchmarks is quite revealing, and the multi-core speeds roughly equivalent to the Ryzen 9 5950X are also very impressive (single-thread performance is much better than the Ryzen chip. , also 27% and 18% faster in CPU-Z and Cinebench respectively).

Another point to keep in mind here is that the 5950X is a 32-thread spiky 16-core processor, compared to the alleged 12900Ks 24-thread configuration (it will run with 8 full-power performance cores and 8 of efficiency, with the latter not having hyper-threading). So the Ryzen chip has an 8 thread advantage here, and remember the final retail 12900K chip could do even better, especially if paired with DDR5 RAM (DDR4 is used in this series of tests, as indicated).

If there is any area of ​​concern at first glance, it’s power consumption reaching 257W in the stress test here, and temperatures reaching 108C – but that’s to do with the seemingly rigged cooling solution ( it was not correctly fitted), the leak had to use here. In other words, take this with a lot of condiments, and the thermal performance of the actual finished product will be much better (probably in the same range as the 11900K).

All in all, this is a very promising leak for Intel, and yet another that seems to suggest that Alder Lake could be a real headache for AMD and its Ryzen dominance on desktops.
