There's a single benchmark for measuring how long it takes to compile Chrome. That doesn't tell, say, the average IDE user how well it'll handle their interactive experience – it's reasonable to expect that to multithread well – or what the workload the original poster specifically mentioned will be like. Many web developers have e.g databases, redis, CSS/JS compilers, etc. running (directly, in Docker, etc.) in addition to the app, and many of those bottleneck on single-threaded performance, and so it's quite reasonable to ask whether that kind of workload benefits from the extra parallelism which is the main selling point for this processor design.
It seems to average 10-20 compiles a day... And it's Chromium compilation. That probably averages 1-2.5 hours per compilation. Compiler as a benchmark depends a lot on moving data and jumps from all the parsing, codegen, dataflow analysis, etc.. It's definitely not a floating point heavy benchmark.
