The main focus of my reviews has always been about CPU performance
in real world engineering benchmarks, and this is where things
take a dramatic turn with the Mac Studio. To really convey my
experience, I want to set the stage with previous results from the
computational fluid dynamics (CFD) benchmark I’ve been running for
the last 10 years. These results cover four generations of pro
desktop Mac systems running Intel CPUs. [...]
As shown above, we see a pretty typical trend where machines get
less and less efficient as more and more cores join the
computation. This happens because the computational work begins to
saturate communications on the system as data and MPI instructions
pass between the cores and memory, creating overhead. It’s what
makes parallel CFD computations such a great real world benchmark.
Unlike simpler benchmarks that tend to make CPUs look good, the
CFD benchmark stresses the entire system and shows us how things
hold up as conditions become more and more challenging.
Now let’s take a look at what happened when I repeated this test
for the Mac Studio and plotted results on the same chart.
Off the chart, literally.
