The latest alleged benchmarks of the flagship Intel Core i9-12900K Alder Lake have been leaked and they show that they once again beat the AMD Ryzen 9 5950X in single-threaded tests.
Intel Core i9-12900K Alder Lake crushes AMD Ryzen 9 5950X Zen 3 processor in single-thread benchmark with 27% lead
The Intel Core i9-12900K will be the flagship chip in the 12th generation Alder Lake family. The processor will feature a total of 16 cores and 24 threads with clock speeds of up to 5.30 GHz (TVB) and 30 MB of L3 cache. The chip will feature a TDP of 125W (PL1) and 228W (PL2). We have already gotten several benchmarks of the chip in various other tests that show it to run faster than Ryzen Threadripper and Ryzen 5000 processors, but the last benchmark entry is in CPU-z.

The benchmarks leaked by Bilibili allegedly feature the Intel Core i9-12900K and while we don’t have details on the test setup, we can see the processor scores 825 points in the single-core test. Compared to the existing flagship, the Core i9-11900K, this is a 21% single-core performance increase, and compared to AMD’s Ryzen 9 5950X, this is a single-core performance increase. by 27%.
Intel Alder Lake processors aim to deliver a 19% improvement in CPI, so a 21% improvement over Rocket Lake chips is roughly in line, given that there are other architectural improvements as well. We can’t say how valid these tests are, but in everything we’ve seen so far, the i9-12900K literally outperforms every chip with a 20-30% lead in single-core tests.
Intel Core i9-12900K also tested in SiSoftware Sandra Benchmark Suite
SiSoftware benchmark suite developer Sandra has also released the very first benchmarks for the Intel Core i9-12900K. Note that these figures are not from a processor tested by the developer, but rather from benchmarks submitted by third parties in the database on SiSoftware. We’ve seen SiSoftware’s benchmark results for the Core i9-12900K before.
In testing, the Intel Core i9-12900K chip was seen to be seriously lacking compared to its predecessor, but also showed a huge increase in AVX2 performance despite the fact that it does not support AVX-512 like the Intel range. RKL (Rocket Lake). The SiSoftware benchmarks are inconclusive, which is why we just wanted to make a small mention of it in this article. Also, since the link on the above post is down, credits are given to Videocardz for sharing the benchmark results.

The leaker didn’t show the multi-core performance benchmark, but hinted that it was also very strong compared to the AMD Ryzen 9 5950X. With this performance, the Intel Core i9-12900K could certainly take on Intel’s high-end AM4 chips and might just have enough juice to compete favorably with the Ryzen 3D chips which are expected to bring another 5-hour performance boost. at 10%. It looks like the CPU segment is back in action with the two x86 rivals pitted against each other in a long overdue and much needed battle. If Alder Lake turns out to be the success Intel has long been waiting for, then their next goal should definitely be to return to the HEDT market.
