According to the latest PassMark benchmarks, the Intel Core Ultra 9 285K is the highest-performing single-thread CPU. The benchmark king title comes as PassMark's official account on X shared single-threaded performance number, with the upcoming Arrow Lake-S flagship SKU, Intel Core Ultra 9 285K, scoring 5,268 points in single-core results. This is fantastic news for gamers, as games mostly care about single-core performance. This CPU, having 8 P-cores and 16 E-cores, boasts 5.7 GHz P-core boost and 4.6 GHz E-core boost frequencies. The single-core tests put the new SKU at 11% lead compared to the previous-generation Intel Core i9-14900K processor.
However, the multithreaded cases are running more slowly. The PassMark multithreaded results put Intel Core Ultra 9 285K at 46,872 points, which is about 22% slower than the last-generation top SKU. While this may be a disappointment for some, it is partially expected, given that Arrow Lake stops the multithreaded designs in Intel CPU families. From now on, every CPU will be a combination of P and E-Cores, tuned for efficiency or performance depending on the use case. It is also possible that the CPU used inn PassMark's testing was an engineering sample, so until official launch, we have no concrete information about its definitive performance comparison.
