The Accelerator Landscape
Once you accept that some of your work belongs on a throughput engine, you have to pick one, and the market offers far more options than "NVIDIA or not". There are discrete GPUs on a PCIe slot, GPUs integrated into the same die as the CPU, phone-class GPUs paired with NPUs, datacenter training and inference ASICs reachable only through a compiler, and FPGAs where you describe the datapath yourself. They differ enormously in peak throughput — and that difference is almost never what decides the outcome.
