CPU for complex control flow, GPU for large-scale parallel computation, TPU for matrix operations pushed to the extreme. For most engineers, the real decision is cloud inference on GPU vs CPU, and when a TPU rental is worth it.
NVIDIA's latest inference optimizations — FP8/INT4 quantization, 2:4 structured sparsity, and TensorRT-LLM system improvements — dramatically increase throughput and cut deployment cost with negligible accuracy loss.
Deploy Ollama on a GPU machine via Docker, then use netsh portproxy on Windows to forward localhost:11434 to the GPU box, so Codex on Windows transparently uses the remote GPU.
