I spent a while profiling why my A770 16GB was "bad" at MoE models, and the answer turned out to be worth sharing. Stack Format Decode llama.cpp SYCL, all layers on GPU Q4_K_M (~4.85 bpw) 14.4 tok/s llama.cpp, CPU only (8 cores) same GGUF 15.5 tok/s OpenVINO GenAI, same card int4 g64 (~4.3 bpw) ~43…
