Is geekbench accurate at comparing across different architectures?
- wizee 6y agoGenerally, yes. The benchmarks are calculating/computing the same things on both architectures, and the various sub-benchmarks are based on real-world non-trivial computational problems rather than microbenchmarks that are easily manipulated by instruction set differences.
- userbinator 6y agoUnless they are written in optimised Asm I would not compare across architectures, because there is considerable leeway in compilers and my experience has shown that a good human can often beat a compiler solidly --- at least on x86. https://www.realworldtech.com/forum/?threadid=185109&curpostid=185132 https://www.realworldtech.com/forum/?threadid=185109&curpost...
- saagarjha 6y agoHow often is software written by a good human?
- ytch 6y agoGeekbench tests daily tasks like AES, PDF, HTML5. If the score is higher, then daily tasks are faster too. IMHO it is reliable across different Arch/CPU/OS.
- YetAnotherNick 6y agoIf anything, I feel like many tests are based on x86 special instructions like AES, which does not directly translate to other tasks. But for most of the tasks I think it wouldn't be possible that the processor are only better at those and performance of most program should correlate with geekbench score.
