Clang's Competition For GCC On Intel Haswell

Written by Michael Larabel in Software on 6 February 2014 at 04:00 AM EST. Page 4 of 4. 29 Comments.

LLVM Clang 3.4 stable came out ahead of the latest GCC stable and unstable series with the Himeno Poisson Pressure Solver.

LLVM Clang 3.4 had a slight advantage with the 7-Zip compression benchmark.

LLVM Clang still easily surpasses GCC in speedy compile times.

LLVM Clang still has some optimization work to do to better enhance the C-Ray multi-threaded ray-tracer -- its performance was tuned by GCC developers over the last few compiler versions.

LLVM Clang also lags behind GCC with HINT.

Overall, these results are fairly competitive between the latest LLVM Clang and GCC -- more so than in the past or even a few months ago with recent versions of these two open-source compilers.

Have a particular compiler benchmark test request? Let us know or better yet feel free to submit your own OpenBenchmarking.org test profile so we can easily automate it and test it with our open-source Phoronix Test Suite software that's quite popular with compiler developers and hardware companies for automated testing/benchmarking. LLVM Clang daily benchmarks are also forthcoming via the new Phoronix test farm.
