CPUBenchmark.net says M3 is faster than all M4s on single thread performance
21–24 of 24 posts
Re: CPUBenchmark.net says M3 is faster than all M4s on single thread performance
#22According to CPUBenchmark.net the M3 Max 16 Core is the fastest single thread cpu with a score of 4,785, followed by the M3 Max 14 Core with a score of 4,771. Although the numbers above are close, it does not make much sense to me that a chip with more CPUs will be faster on single thread performance than the same chip with less CPUs. But I can be wrong. Also, according to their list, even the M3 8 Core beats the M4…
That's far from the only number that looks weird. If this site is legit - a point I'm not conceding - it could be that these numbers are the average of some large number of systems, and the tests are not properly controlled for any of the other factors that might affect performance. Amount of memory, memory speed, single vs dual channel, overclocking, CPU cooler, even ambient temperature could all be having an impact…
Do you know a trustworthy source where I can compare single thread performance of M3s and M4s?

I see. Sorry about that. Won't be putting any more comments in the title. Thanks for your guidance. I HAVE NOW CHANGED THE TITLE => Thanks again!
That's still cherrypicking what you think is important and putting it in the title. Lists of benchmark results (with or without made-up titles) in general don't make good HN posts. You can use the search feature to find lots of M-related threads that can probably answer your specific question, though
If you don't mind suggesting a better title I'll be happy to change it

4785 versus 4771 feels like it's within the bounds of run to run variance
Agree! But how about the M3 8 Core (4754) beating the M4 Max 14 Core (4614)? I thought the M4s were faster than the M3s (single core / single thread), but it looks like they will only be faster on multi core / multi thread benchmarks. I would think that the sheer speed of a CPU is the single core / single thread performance number.
The number of cores is irrelevant to the measure of single core performance. It is entirely possible that single core performance is less for many reasons up to and including silicon lottery.
Raw performance is also not the only relevant metric. Given that these results are within run to run variance there are other factors to consider such as power consumption.
So yes, this is not at all a shocking revelation to me.
