Intel engineers today released Compute Runtime 25.09.32961.5 as their newest update to this open-source compute stack for Windows and Linux systems providing OpenCL and oneAPI Level Zero GPU compute support. Most notable in this release is rolling out initial “pre-release” support for next-gen Core Ultra “Panther Lake” SoCs with integrated Xe3 graphics.
Going along with the ongoing work to the Intel Xe Linux kernel driver and the Mesa Iris/ANV graphics drivers, the Intel Compute Runtime bring-up has begun for Xe3 / Panther Lake. With the Compute Runtime 25.09.32961.5 release there is “pre-release” level support for Panther Lake with OpenCL 3.0 and oneAPI Level Zero 1.6.
The Compute Runtime has begun enabling various features like direct submission, among others, for Panther Lake “PTL”. Beyond the “pre-release” state the overall state of Panther Lake GPU compute support isn’t clear in the public channels but surely over upcoming Compute Runtime updates you can expect more optimizations and feature work ahead of the Core Ultra Series 3 launching later in 2025.
This Compute Runtime update also continues bringing more improvements for the new Battlemage “Xe2” discrete GPUs with enabling WMTP and other improvements.
There is also other feature work with today’s Compute Runtime update like many commits mentioning a new “ULLS Light” mode being enable for ULLS without VM_BIND usage. ULLS in this context is for Ultra Low Latency Submission. ULLS Light is enabled for now with Arrow Lake and Meteor Lake.
There are also some other performance optimizations like reusing allocations with similar requested sizes and other tuning.
The updated Compute Runtime in source code form as well as pre-built Ubuntu Linux binaries can be found via GitHub.
