 General Purpose graphics processing unit (GPU, GPGPU) processing is one area in which Perl can be compared with compiled languages in performance.Based on their own benchmarks, Perl OpenGL developers claim that there are no significant performance differences between C and Perl (via POGL), when rendering a realtime 3D animated object with dynamically generated texturemaps.They analyze their results by remarking that GPGPU vertex shaders can execute complex C-like code on large arrays of data, rarely touching the CPU.
