CPU vs GPU vs TPU vs NPU vs LPU, explained visually:5 hardware architectures power AI today.Each one makes a fundamentally different tradeoff between flexibility, parallelism, and memory access.> CPUIt is built for general-purpose computing. A few powerful cores handle complex logic, branching, and system-level tasks.It has deep cache hierarchies and off-chip main memory (DRAM). It's great for operating systems, databases, and decision-heavy code, but not that great for repetitive math like matr
