Expert reviews


The Intel Core i9-12900KS is the best a 12th Gen Intel CPU could be, but with the caveats that you're paying more in purchase costs, running costs and cooling costs when compared to the regular 12900K, and for some extra performance but not loads. Whether those are compromises and costs you're willing to make is up to you.


It comes at a price, but the Intel Core i9-12900KS "Alder Lake" processor is the best CPU currently available on Intel's 600 series platform.


Core i9-12900KS has blazing performance but mainly demonstrates how Intel desperately needs to improve power draw and efficiency.
