Processor Benchmarks

Benchmarks are a useful tool in judging a processor’s performance. The pages and links here present a sampling of benchmark data from TI’s optimized libraries, as well as independent benchmarking results.

We have divided TI benchmarks into two major categories:

  • Core benchmarks – focused solely on the performance of a single core type.
  • Device benchmarks – benchmarks at the device level. These may include multiple cores, memory, data movement, and cache effects in the measurement.
