>>> They already have a mobile chip that is as fast as an active-thermally cooled notebook chip.
>> "As fast" on specific curated use cases. Show me an Apple chip that beats any laptop on 7zip.
> Is this a joke, what kind of usage benchmark is 7zipping large numbers of files?
A benchmark that Apple is unlikely to have implemented specific optimizations for, which therefore is a better test of the general purpose performance of the chip.
The situation being claimed here is sort of like if someone cited a DES benchmark to claim that Deep Crack's DES cracking chips (https://en.wikipedia.org/wiki/EFF_DES_cracker https://en.wikipedia.org/wiki/EFF_DES_cracker) were faster than a contemporary 1998 Pentium II.

- ardy42 6y ago> A benchmark that probably relies as much on disk access speeds as CPU? If true, that's just a nitpick that doesn't affect the overall point of the GGGP, though.
- user5994461 6y agoNope, 7zip is using LZMA algorithm for compression, which is around a few MB/s on the fastest CPU. It's heavily CPU bound. edit: Just tried compressing a large file, ultra setting on my desktop i5 CPU, it's running at 3 MB/s on 1 core.
- stjohnswarts 6y agoNot true. the bottleneck is going to be compression not disk access.
