Can CPUMark values be compared across different platforms? Ie. does a value of say, 1000 CPU Mark on Windows, Android, and iOS mean that the three cpus are has about the same performance?
Our original plan was to have the CPUMark directly comparable across multiple platforms.
But it is harder than it sounds.
There are differences in programming languages, compilers, how much RAM is available, how multi-threading is done, what functions are available in each different operating system and what 3rd party libraries are available. For example we saw huge differences in encryption performance depending on if hardware accelerated AES was available and exposed via the O/S API.
In additional we are about to release PerformanceTest V8 on Windows. And some the CPU tests have changed in PT8.
So as a result we aren't really recommending direct comparison of the CPUMark value between Windows and mobile platforms.
