LLVM Clang 21 Compiler Helping Squeeze More Performance On 5th Gen AMD EPYC "Turin"
2 septembre 2025 à 16:42
With LLVM 21.1 having been released last week as the newest half-year feature update to this open-source compiler stack, I have begun benchmarking Clang 21 on a variety of systems for getting a feel for the performance over Clang 20. Eventually it will be extended as well to looking at the Clang 21 performance against GCC and vendor compilers. For some initial Clang 21 benchmarking, here is a look at how the Clang 21 C/C++ compiler is performing on 5th Gen AMD EPYC "Turin" Zen 5 processors compared to the prior release.
