What is GPU Compute?
Using graphics processing units for parallel mathematical operations that power AI training and inference.
Definition
GPU compute refers to the use of Graphics Processing Units for the massively parallel mathematical operations required by AI workloads. GPUs contain thousands of cores optimized for matrix multiplication — the fundamental operation in neural networks. NVIDIA dominates the AI GPU market with its CUDA ecosystem, H100, and B200 chips. GPU compute is measured in FLOPS (floating-point operations per second) and is the primary bottleneck and cost driver for AI development. A single GPT-4-scale training run requires thousands of GPUs running for months, costing tens of millions of dollars.
Examples
Why It Matters
GPU compute scarcity and cost directly determine AI model pricing, availability, and capabilities. Understanding compute economics explains why AI subscriptions cost what they do and why some models are faster than others.
Related Terms
TPU (Tensor Processing Unit)
Google's custom AI accelerator chip designed specifically for tensor operations in machine learning workloads.
AI Inference Optimization
Techniques that make AI models generate responses faster and cheaper without reducing output quality.
Mixed Precision Training
Training neural networks using a mix of 16-bit and 32-bit floating-point numbers to save memory and increase speed.
Data Parallelism
Distributing training data across multiple GPUs that each hold a copy of the model, then synchronizing gradients.
