PTXBench measures performance of AI-generated GPU kernels
Published on September 29, 2026, PTXBench evaluates matrix multiplication and attention kernels in architecture-specific PTX on H100 and B200 GPUs, measuring correctness, speed, and whether requested instructions are actually executed.

What happened and what to do
The PTXBench evaluation, published on September 29, 2026, tests models that generate matrix multiplication and attention kernels in architecture-specific PTX for H100 and B200 GPUs. It measures correctness, speed, and whether requested instructions are actually executed, providing a way to identify limitations compared with specialized libraries.
A company that generates or maintains GPU kernels could implement an internal benchmark suite to run representative cases, verify results, and record latency, throughput, and the instructions actually used. A pipeline can repeat tests after model, code, or hardware changes, while a dashboard compares versions and flags regressions. The goal is to validate performance and behavior, not to assume generated code is faster than a specialized library.
How the consultancy can help
Wendelmaques can diagnose how your team evaluates GPU kernels, define relevant test cases and metrics, and deliver a test harness, execution pipeline, and comparison dashboard. The scope can include operating and maintaining the evaluation on the company’s infrastructure.
