The Ubuntu Kernel Team issued a statement this morning to proactively warn Ubuntu Linux users on Ubuntu 26.04 and Ubuntu 24.04 LTS HWE users that the next kernel point release will contain a performance regression for AMD GPUs in compute-heavy workloads with up to a 42x performance hit. The positive news is that due to this being an upstream regression in a Linux 7.0 point release, upstream stakeholders and other Linux distributions that more quickly shipped the problematic code already have a fix coming down the pipe...

Earlier this month on Phoronix I reviewed the Razer Blade 18 RZ09-0582 as the first laptop Razer is certifying for Linux use via Canonical's hardware certification program for Linux. It offered very nice performance with the Intel Core Ultra 9 290HX Plus and NVIDIA GeForce RTX 5090 graphics albeit costly with a configured price of $5399 USD. That review featured benchmarks on Ubuntu 26.04 LTS but for those wondering about the performance of Ubuntu against Windows 11 on this gaming/AI developer laptop, here are comparison benchmarks plus also tossing in the rolling-release CachyOS distribution.
