You must be unfamiliar with VBA macros, as they also are all unoptimized. This benchmark is perfect as it represents exactly what is mostly ran on excel(Which is code made to just work, only sometimes optimized for speed). Someone who spends most their time working with these custom excel subroutines/functions appreciates how accurately this test reflects their true workload and is then able to avoid processors whose performance is sometimes 4 times slower than a comparable chip. I am really excited to see how Ryzen has stepped up its IPC and made AMD competitive, have yet to see how it performs on this benchmark.
Show me a better Excel benchmark that reflects true macro performance? Until then, this is my go to for comparisons to show coworkers and clients on what is slowing down there work.
