👁 LocalScore benchmark with settings of Model: Qwen2.5-14B-Instruct-Q4_K_M.gguf, Acceleration: CPU. Linux 6.15 was the fastest.

👁 LocalScore benchmark with settings of Model: Qwen3-32B-Q4_K_M.gguf, Acceleration: CPU. Linux 6.15 was the fastest.

With the LocalScore AI benchmark built off Llamafile/Llama.cpp as a Mozilla Builder's project, there were some minor improvements to find out of upgrading to Linux 6.15.

👁 PyTorch benchmark with settings of Device: CPU, Batch Size: 1, Model: ResNet-50. Linux 6.15 was the fastest.

👁 PyTorch benchmark with settings of Device: CPU, Batch Size: 16, Model: ResNet-50. Linux 6.15 was the fastest.

👁 PyTorch benchmark with settings of Device: CPU, Batch Size: 64, Model: ResNet-50. Linux 6.15 was the fastest.

Similarly, in PyTorch there were some small but consistent improvements to find when running PyTorch off the Linux 6.15 kernel on this dual AMD EPYC 9755 server.

👁 OpenVINO benchmark with settings of Model: Face Detection FP16, Device: CPU. Linux 6.14 was the fastest.

👁 OpenVINO benchmark with settings of Model: Person Detection FP16, Device: CPU. Linux 6.14 was the fastest.

👁 OpenVINO GenAI benchmark with settings of Model: TinyLlama-1.1B-Chat-v1.0, Device: CPU. Linux 6.15 was the fastest.

Not all of the workloads though exhibited better performance with this single kernel version upgrade and in some cases very tiny uplift.

👁 Xcompact3d Incompact3d benchmark with settings of Input: X3D-benchmarking input.i3d. Linux 6.15 was the fastest.

👁 OpenRadioss benchmark with settings of Model: Bumper Beam. Linux 6.15 was the fastest.

It tended to be in the heaviest AI and HPC benchmarks where Linux 6.15 was yielding improvements over Linux 6.14 on this high-end 5th Gen AMD EPYC server.
