Parallel by design
GPUs gain throughput by running very large groups of similar operations. Branching and irregular work can reduce that efficiency.
PROCESSING ATLAS
Graphics Processing Unit
A graphics card combines a highly parallel processor, dedicated memory, power delivery, and cooling on a PCIe expansion board.
Representative form: dual-fan desktop PCIe graphics card. Board layout and cooling vary by product.
Memory bandwidth matters
Rendering and compute often move large data sets, so memory bus width, speed, cache, and data reuse work together.
The card is a system
A discrete GPU product is more than the processor: PCB, firmware, memory, power conversion, cooling, and host software all shape results.
