Following this week’s updated Intel Graphics Compiler release, a new version of the Intel Compute Runtime was also published in providing OpenCL and oneAPI Level Zero GPU compute support on Windows and Linux systems.
The new Intel Compute Runtime 25.13.33276.16 release brings various bug fixes, continued preparations for next-generation Xe3 graphics initially debuting in integrated form with Panther Lake SoCs, and various performance tuning/tweaks. The Xe3 work continues steadily across the open-source Linux graphics driver stack ahead of Core Ultra Series 3 “Panther Lake” SoCs debuting later in 2025.
On the performance side with this new Compute Runtime release is improving ULLS light residency management, caching timestamps now on the CPU, introducing staging reads for cl_buffer, configuring Xe2 compression, power efficient waits with ULLS light mode, setting a 1ms timeout for the ULLS controller on Lunar Lake and Panther Lake hardware, and other changes. The Intel Compute Runtime also now supports setting the low-latency hint for the i915 kernel graphics driver to help with performance for light OpenCL/LevelZero workloads. This low latency workload can help such light workloads “a lot” according to the commit.
The new Compute Runtime release also now enables defer backing by default when using the Xe kernel driver and various other changes.
