KDE Plasma 6.6 Showing Frequent Performance Advantage Over GNOME 50 With NVIDIA R595 Driver

Earlier this week I provided benchmarks looking at KDE Plasma 6.6's performance advantage over GNOME 50 for Linux gaming with AMD Radeon graphics. That raised the question if the same was true when using NVIDIA graphics with their official Linux graphics driver stack. Here are such benchmarks looking at the KDE Plasma 6.6 and GNOME 50 performance on Ubuntu 26.04 beta while using the new NVIDIA 595.58.03 Linux driver.

Intel Xe Driver Improves Memory Pressure / Out-Of-Memory Behavior For vRAM With Linux 7.1

Following the Intel Xe kernel graphics driver pull request landing transparent hugepages for device pages as an SVM win, another round of Intel Xe driver updates were sent out this week ahead of next month's Linux 7.1 merge window. This latest pull request lands a new user-space API for helping the Intel Xe driver better cope with situations of video memory pressure / out-of-memory behavior for vRAM...

Linux Patches Posted To Fix ~2x Performance Drop For CPU Workloads On NVIDIA Vera Rubin

An important set of Linux scheduler patches were posted for review on Thursday for improving the SMT-aware asymmetric CPU capacity handling. These patches to improve the Linux kernel scheduler around CPU Simultaneous Multi-Threading (SMT) is needed after NVIDIA engineers discovered up to a ~2x performance drop for CPU-intensive workloads on their upcoming Vera Rubin platform...

Open-Source Nouveau Performance With Linux 7.0 + NVK Mesa 26.1-dev vs. NVIDIA Linux Driver

As a few months have passed since our prior round of testing the fully open-source NVIDIA Linux driver stack with the Nouveau kernel driver and Mesa NVK Vulkan driver plus Zink, here is a fresh round of benchmarks using Linux 7.0 and Mesa 26.1-dev compared to the open-source stack shipped by Ubuntu 25.10 (Linux 6.17 + Mesa 25.2) for showing how far the open-source NVIDIA driver has progressed the past few months. Plus testing against the NVIDIA official Linux graphics driver for putting that Nouveau/NVK performance into perspective.

Intel Xe Driver In Linux 7.1 Enabling THP For Device Pages As A Big SVM Win

Sent out today was a new batch of "drm-xe-next" material of Intel Xe kernel graphics driver improvements ready for the upcoming Linux 7.1 kernel cycle. Standing out in this pull is enabling Transparent Hugepages (THP) support for drm_pagemap as a big win for those making use of Shared Virtual Memory (SVM) for GPU compute and the like...
