Anandtech shows[0] that M3 is massively ahead in integer performance, but slightly behind in float performance on Spec 2017.

Integer workloads are by far the most common, but they tend to not scale to multiple cores very well. Most workloads that scale well across cores also benefit from big FP/SIMD units too.

Put another way, the real issue with R24 is that it makes HX370 look better than it would look in more normal consumer workloads.

> that M3 is massively ahead in integer performance

The M3 is certainly an impressive chip, but note that it's only massively ahead in some of the int tests. It's not a consistent gap.

The HX370 does better than the Me in specint MT though.

But regardless the anandtech results paint a much closer picture than the single R24 results that GP used as the basis of the efficiency thesis.


The HX370 should win in SPECINT MT. It has 12 cores to the M3's 8 cores and it runs at significantly higher power.

Compare HX370 SPECINT MT To an M3 Pro and let's see the results.


> [HX370] runs at significantly higher power.

It used 33w. Meanwhile the M3 result came from a 2023 MacBook Pro 14-Inch, which certainly has the potential for a TDP of around that. If you can find SPECINT MT numbers w/ power data for an M3 Pro lets see it. Or even just power data for an M3 non-pro in the 14" MBP. A quick search isn't turning up any.


M3's CPU uses around ~10w while running ST tasks.

The ~30w TDP of an M3 Pro is if it's running CPU and GPU tasks at max load.
