Intel Core i9-12900KS 5.5GHz Alder Lake Totally Smokes Ryzen 9 5950X In Benchmark Leak
Well, thanks to its extra gear in clock rate, the Core i9-12900KS widens the gap even further. We haven't gotten our hands on one to test yet, but Reddit user /u/Seby9123 apparently did somehow, and put it through its paces in CPU-Z and in Cinebench R23.
The results are exactly what you expect: it's a little bit faster than a 12900K. In Cinebench R23, the Core i9-12900KS scores 2162 points on a single thread and 29164 points across all threads. In the CPU-Z benchmark (version 17.01.64), it scores 883.4 on a single thread and 12232 across all threads. Both benchmarks were done at stock, with DDR5 memory running at 6200 MT/s.
Seby9123 confirmed that, as Intel claimed, the CPU does in fact hit 5.2 GHz on all P-cores while doing 5.5 GHz on two. Surprisingly, the Core i9-12900KS runs the same uncore or "ring" frequency as the Core i9-12900K, 3.6 GHz. Overclockers have found that raising this frequency, which is normally linked to the E-core clock, can give big performance gains.
Cinebench is a single benchmark, and while not completely synthetic—it tests performance for Maxon's Cinema4D renderer—it nevertheless is not particularly representative of performance in other mainstream tasks and even other content creation workloads. With that said, considering this high score is coming from a CPU with ludicrous single-threaded performance, we would expect Seby9123's Core i9 12900KS to pretty much flatten all comers in gaming benchmarks as well.
We'll have to see how this thing ticks when it hits the market April 20th.
