Why GPUs go Vroom:
- Thousands of simple cores (Streaming Multiprocessors/Compute Units) designed for parallel tasks.
- SIMT Architecture (Single Instruction, Multiple Threads): Warps/Wavefronts execute the same math on different data simultaneously.
- High Bandwidth Memory (HBM): Stacked directly on the chip for massive data throughput.
- Tensor Cores: Specialized hardware units hardwired to perform 4x4 matrix multiply-accumulate (MMA) operations in a single clock cycle.
- Latency Hiding: Fast context-switching between thousands of threads keeps the math cores busy while waiting for memory fetches.
