Ok, I trust you on this one :)
Maybe Sandra didn't cover a large enough area, and a significant portion of their accesses are hitting L3.

My opinion is requiring a license reduces its value as a benchmark. It means you won't have a lot of runs from the general public and less data to compare against.

They don't try porting across operating systems and architectures because most of them don't care and don't have an audience that cares. It's also why you don't see a lot of Mac OS benchmarks floating around - Apple market share is small.

And yeah looking at new architectures is interesting. To me, SPEC is in the position of 'better than nothing at all'.

If you want an example of a site that cares about cross-platform, Phoronix got their hands on a Mac Mini and have run a lot of tests including Rosetta ones. I like how they include Darktable - RAW conversion perf is interesting to me personally. It's just inconvenient to look up test scores for other non-mac configs on openbenchmarking.org.

The Phoronix test suite still has a lot of weird 'who uses this' tests, but it also has some relevant stuff and is starting to look like SPEC done right.
