โก Architecture & Throughput Transparency: Single-user decode speed (~52 tok/s) is memory-bandwidth bound at batch size = 1 on Apple Mac Studio M5 Ultra (256GB Unified Memory) (890 GB/s). Prompt prefill / TTFT (~754 tok/s) is compute-bound and utilizes GPU Tensor cores. Actual latency varies with FlashAttention-2 and runtime engine (Ollama/vLLM/llama.cpp).
