TPUs, Trainium and Custom Accelerators: Where Non-GPU Silicon Wins
A GPU is a general parallel computer that happens to be excellent at matrix multiplication. A purpose-built accelerator is a matrix multiplier that happens to be programmable. Everything that follows — the efficiency, the compiler, the sharp edges — comes out of that one difference. Why non-GPU silicon exists at all Generality costs area and power. A GPU carries instruction fetch and decode for…
