AMD Ryzen 9 5950X + GCC 11 Compiler Benchmarks At Varying Optimization Levels
For workloads relying on a lot of hand-tuned code, there doesn't tend to be much of a difference.
Link-time optimizations pay off for run time but still carry significant build time implications, though some LTO options can help reduce that build time impact.
Those wanting to see more of these early GCC 11 tuning benchmarks on various workloads can continue checking them out via this OpenBenchmarking.org result file. GCC 11.1 as the first stable GCC 11 compiler release should be out in March~April so you can expect to see more compiler benchmarks on Phoronix leading up to that annual release.
