After recently noticing the [1]Intel Arc B580 performing better on Linux 7.1 for that kernel version soon to be released as stable, I was curious if there were performance gains also to be found with the new flagship Arc Pro B70 BMG-G31 workstation graphics card. Here are some benchmarks of the Intel Arc Pro B70 in relevant workloads between Linux 7.0 and the near-final [2]Linux 7.1 kernel.

With the consumer Intel Arc B580 graphics card showing some decent graphics performance improvements on the new Linux 7.1 kernel, I was curious how widespread these Xe2 Battlemage improvements were and so my next focus was on evaluating the Arc Pro B70 with that new kernel and workloads relevant to that workstation part with 32GB of RAM.

Ubuntu 26.04 LTS was running on the system and Linux 7.0 and Linux 7.1 Git were compared using a similar Kconfig between kernels for checking out the kernel performance impact. Mesa 26.1.2 was in use while testing both kernels as was the latest Intel Compute Runtime and SYCL support.

Let's see what Linux 7.1 is doing to the Intel Arc Pro B70.
