There was a version of Geekbench a while ago for which you could make a good argument for that but Geekbench 5 seems to tell the same story that Spec, web tests, etc all tell. Apple's cores really do seem to be that good though they benefit from running at the clock speed they were designed for, unlike an Intel U-series which has more pipeline stages than it needs to hit its clock.
And Apple also benefits from being able to set their own page size and probably from getting to have caches that are virtually indexed and physically tagged rather then physically indexed and physically tagged. Doing address translation in parallel with way lookup is a nice little performance boost. There are rumors of other cleverness in the cache heirarchy from control of the OS but I don't know the details.
- fulafel 7y agoWhere can I see these SPEC results for Apple CPUs?
- opencl 7y agoAnandtech frequently includes SPEC results in their reviews. https://www.anandtech.com/show/14892/the-apple-iphone-11-pro-and-max-review/4 https://www.anandtech.com/show/14892/the-apple-iphone-11-pro...
- fulafel 7y agoThanks! These are SPEC2006 which is already retired, but those numbers for the A13 do indeed come in the same ballpark as the last official SPEC2006 results that were published for Xeons in 2017 before retirement.
- altmind 7y agospecint2006 shows that A13 outperforms desktop ryzen 3900x. 5W vs 105W. 6 cores vs 12 cores. something is wrong with numbers here.
