The Big Picture

AI does the same math on millions of numbers. A GPU shines here because it runs huge numbers of those operations side by side.

CPU vs GPU Mindset

A CPU has a few fast cores for varied tasks. A GPU trades that for thousands of simpler cores built for raw parallelism.

What Tensor Math Looks Like

Training and inference are mostly matrix multiplies and element-wise ops. These are exactly the regular patterns a GPU loves.

Many Tiny Jobs at Once

Adding two large vectors is millions of independent additions. Each one can run on its own GPU thread with no waiting.

out[i] = a[i] + b[i]

Throughput Over Latency

A GPU may start each task a touch slower, but it finishes a mountain of them together. You win on total throughput.

Memory Bandwidth Matters

GPUs feed those cores with very wide, fast memory. High bandwidth keeps thousands of threads supplied with data.

When a GPU Pays Off

The win is biggest when work is large and uniform. Tiny or branch-heavy jobs may run better on the CPU.

Why Mojo Cares

Mojo aims to write CPU and GPU code in one language. You express the parallel idea once and target the device that fits.

From Python to the GPU

Python usually offloads to GPU libraries it cannot see inside. Mojo lets you write the fast kernel yourself, in readable code.

A Mental Model

Picture one instruction handed to thousands of workers, each on its own slice of data. That is the GPU's core strength.

Not a Magic Button

A GPU helps only if you keep it busy and fed. Poor data movement can erase the gain, so the workload shape matters.

Quick Check

You must decide which workloads truly benefit from a GPU.

Recap

GPUs trade few fast cores for thousands of simple ones, so large uniform tensor math runs in parallel for huge throughput. 🚀
