User reports Qwen3.5-9B at 49 t/s generation and 48 t/s prompt processing on an Intel Arc A770 16GB. Setup is llama.cpp b9521 (Vulkan) with Q6_K weights, q4_1 KV cache, 256K context, flash attention, vision mmproj and MTP speculative decoding on a single slot. The same model under WSL2 with Q8_0 KV cache and 128K context reached about 40 t/s without vision. Qwopus3.5-4B-Coder hit 64 t/s generation and 100 t/s prompt at 96K context, and Gemma 4 12B reached 22 t/s generation and 74 t/s prompt at 128K context.

User reports Qwen3.6-27B-A3B-Coder at 14.4 t/s decode on an Intel Arc A770 16GB, scoring 10/10 on a Lua CSV parser acceptance task. Setup is llama.cpp with the SYCL backend and GGUF Q4_K_M weights, a comparison point against arcint's own AWQ IR serving on the same card. The figure is described as a rough bound rather than a directly comparable measurement, since the quantisation and engine differ from arcint's production configuration.

User benchmarks Qwen3-1.7B at 33.2 tok/s on an Intel Arc A770 16GB using llama.cpp with the SYCL backend. Setup is llama.cpp SYCL with Q8_0 quantisation, single-stream (n_parallel=1). OpenVINO via OVMS reached 65.4 tok/s on the same model. Ten models were tested in total, with OpenVINO faster than SYCL on every model.

User reports Qwen3.8 27B at 12 t/s on an Intel Arc A770 using pure K-quants. Setup uses the SYCL backend, where I-quant mixes like Unsloth's UD-Q3_K_XL run at 7 t/s while pure K-quants like Bartowski's Q3_K_S run at 12 t/s. The user notes SYCL is bottlenecked by inefficient I-quant handling. The user is looking for the smallest K-quant-only Qwen3.8 27B at q3, with Bartowski's Q3_K_S at 12.7 GB as the current top contender.
