FP32

precision
Also known as: single precision

Definition

Single-precision 32-bit floating point, the long-standing default for general-purpose computing and the baseline most GPU specifications quote. Largely superseded by lower precisions for AI, where FP32 throughput is now a small fraction of a chip's tensor performance.
