Intel Core i9-12900KS Benchmarks:

Note: an AIO is recommended at minimum for the i9-12900KS - these tests were performed with a custom loop, and we highly recommend one if you intend to overclock this processor.


Cinebench tests processors for responsiveness and power in both intensive tasks (multi-core) and general daily usage tasks (single-core). And these are some absolutely mind-blowing numbers, blowing away every non-workstation processor currently available.


AIDA64 similarly tracks the raw power of CPUs in a variety of real-world sims, offering a deeper understanding of what the processor is capable of. We ran it through several tests, including AES, PhotoWorxx, Queen, SHA3, and ZLib, as well as several FPU tests (a far more intensive test, such as Julia, Mandel, and SinJulia). Every single one of them demonstrated the absolute raw power the i9-12900KS has to offer and it is a lot. Check out our results below:
