Recent benchmarks of the Intel Core Ultra 9 285K "Arrow Lake" have surfaced on Geekbench 6, revealing that it outperforms the Intel Core i9-14900KS and AMD Ryzen 9 9950X in both single-core and multi-core performance. The tests were conducted on an ASUS ROG STRIX Z890-A Gaming WIFI motherboard, a model that supports the new LGA 1851 socket, which will accompany the launch of Intel's Core Ultra 200 series CPUs. The system was equipped with 64GB of DDR5-6400 memory, a typical configuration for this platform. Given that these boards can handle memory speeds exceeding 8000 MT/s, even higher performance can be expected with faster memory configurations.

The Intel Core Ultra 9 285K, based on the Arrow Lake-S architecture, features a total of 24 cores, configured with 8 performance cores (P cores) and 16 efficiency cores (E cores). The processor operates at a base frequency of 3.7 GHz and can boost up to 5.7 GHz. It includes 36 MB of L3 cache and has a TDP of 125 W (PL1). For sustained performance, the P cores can reach up to 5.4 GHz, while the E cores can achieve up to 4.6 GHz.

In the benchmarks, the Intel Core Ultra 9 285K achieved a single-core score of 3449 points and a multi-core score of 23024 points. These results place the processor ahead of the Core i9-14900KS by ~8% in single-core performance and ~5% in multi-core performance. Compared to the Ryzen 9 9950X, the Core Ultra 9 285K offers a 4% advantage in single-core tests and a 14% advantage in multi-core tests. 

A Core i9-14900KS operates at a higher clock speed of 6.2 GHz, surpassing the Core Ultra 9 285K by 500 MHz, the latter benefits from improved IPC, leading to its performance edge. The Core Ultra 9 285K also demonstrates better power efficiency, with an estimated power draw approximately 100 W lower than that of the Core i9-14900KS, which can exceed 300 W.

The Intel Core Ultra 9 285K surpasses the Core i9-14900K by a good 11% in single-core performance and 10% in multi-core tests.
