AI Hardware Basics
- AI algorithms run on chips, often AI accelerators similar to graphics chips.
- These chips excel at processing vast numbers of math operations quickly, enabling AI's boom.
GPUs vs. CPUs
- GPUs and CPUs perform parallel processing, but GPUs handle far more.
- GPUs use tensor cores for matrix multiplication, giving them the speed for large AI models.
GPUs and AI
- GPUs weren't initially designed for AI but their parallel processing power is surprisingly useful.
- They efficiently perform the same operation on many parallel inputs, ideal for AI workloads.
