The Intel Core i9-12900KS Review: The Best of Intel's Alder Lake, and the Hottest

CPU Benchmark Performance: Legacy and Web

In order to gather data to compare with older benchmarks, we are still keeping a number of tests under our ‘legacy’ section. This includes all the former major versions of CineBench (R15, R11.5, R10) as well as x264 HD 3.0 and the first very naïve version of 3DPM v2.1. We won’t be transferring the data over from the old testing into Bench, otherwise, it would be populated with 200 CPUs with only one data point, so it will fill up as we test more CPUs like the others.

The other section here is our web tests.

We are using DDR5 memory at the following settings:

• DDR5-4800(B) CL40

Legacy

Focusing on our older Legacy benchmarks, the Core i9-12900KS is consistently the best performer of all of the processors on test. The additional frequency bumps to both the Performance (P) and Efficiency (E) cores make it slightly better than the Core i9-12900K.

Web

Looking at the performance in our web-based tests, the Core i9-12900KS again beats the competition pretty comprehensively, including the Core i9-12900K, the AMD Ryzen 9 5950X, and the Ryzen 7 5800X3D.
