Summary

User reports 50.070235 t/s generation and 442.1505415 t/s prompt processing.

Hardware GMKtec EVO-X3, Radeon 8060S gfx1151, 128GB unified memory (Strix Halo). CPU SKU and core counts not established by this article alone. Selected model Qwen3-Coder-30B-A3B-Q4_K_M, GGUF, llama.cpp Vulkan v0.6.4 build 10565 commit baf6360be (author short commit; full revision unknown). Selected measured context depth 32768 tokens already present before the operation; this is occupied depth, not allocated capacity. Microbatch 2048, batch2048, all available layers offloaded, Flash Attention enabled, Q8_0 K and V cache, one server slot, no-host loading. Native generation tg128 at that measured depth: 50.070235 tokens per second. Native prompt processing pp512 at the same depth and microbatch: 442.1505415 tokens per second. These are separate operation cells of the same matched synthetic configuration, not a single combined request or end-to-end rate. The author reports median of launch means. This 32K comparison used two launches per backend in ABBA order. Mesa26.3.0-devel RADV, libdrm2.4.134, shaderc2026.3-dev. IOMMU stayed enabled; no thermal, firmware or power-policy changes. Server slot count does not prove request concurrency; no concurrent request rate is inferred. Exact tested quant conversion repository, filename, checksum and revision are not published. Resident weight allocation and RAM consumption are unspecified. Original article https://www.soothill.io/blog/2026/08/19/vulkan-064-rocm-714-strix-halo/ .

Verified publisher model link https://huggingface.co/Qwen/Qwen3-Coder-30B-A3B-Instruct is a base-model reference, not the tested Q4_K_M artifact. Other backends, shallow cells, microbatches and served MTP requests are separate tests and must not be combined with the selected 32K synthetic cells.
