You can try the binary on your CPU.
This particular workload does not make much difference between modern CPUs. I just tried the Sunspider benchmark on my skylake and it has similar outcomes as reported, but there is more noise since it is notebook
What I got is:
GCC 8 build: 333 +- 3.3%
Tumbleweed distro firefox: 352 +- 3.4%
Firefox 63 (GCC) official binary: 346 +- 5.6%
Firefox 64 (llvm) official binary: 342 +- 5.1%
but I do not completely trust the numbers as re-running the benchmark leads to different outcome each time
