Intel Core Ultra 9 285K Performs Better on Linux Than Windows
The Intel Core Ultra 9 285K shows improved performance on Linux compared to Windows, with gains in various workloads.
Intel's new Core Ultra 9 285K has shown surprising performance results, running significantly faster on Linux than on Windows. While the chip received a lukewarm reception initially due to its middling performance, it seems switching to Linux could unlock its full potential. Linux Outperforms Windows the Core Ultra 9 285K ran an average of 5% faster on Ubuntu 24.10 compared to Windows 11 (24H2). Furthermore, upgrading the Linux kernel to 6.13 resulted in an 7% performance increase over Windows. This suggests that the chip's performance is being held back in the Windows environment. Performance Analysis In specific workloads, the 285K showed significant performance differences between the two operating systems: Windows Struggles: Rendering, ray tracing, compression/decompression, encoding, Java, and some chess simulators performed poorly on Windows. Linux Gains: In one SVT-AV1 encoding test, the 285K was nearly twice as fast on Ubuntu as on Windows. Many other tests showed double-…
