The Core Ultra 9 285K, a new flagship desktop CPU from Intel that is said to feature the same 24-core (8P+16E) configuration as the current flagship but with a notably slower Thermal Velocity Boost Frequency of 5.7 GHz, is now number one on PassMark’s list of CPU Mark rankings for single-threaded performance. The “Arrow Lake-S” CPU, which is reportedly being announced next week, achieved a score of 5,268, putting it in the top spot ahead of the Core i9-14900KS, which now sits in second place with 4,868 points. A ranking of the top-10 CPUs with the best single-thread performance based on CPU Mark can be found below.
This chart comparing the single thread performance of CPUs is based on the average PerformanceTest benchmark results from millions of machines and is updated daily. It focuses exclusively on single-threaded performance, meaning each CPU is assessed based on its ability to perform a single task at a time. The results are categorized according to the typical use of the CPUs, such as Laptop, Server, etc.
