With the release of the new M3 Ultra Apple Silicon chip there is a new proverbial “king” of Mac performance/specs, as this chip is aimed at the professional market and features the highest specs in the Mac lineup in Early 2025. While new product performance is often touted and contrasted against old products during launch at Apple, we often don’t get to see raw CPU and GPU benchmarks until we get one in our hands or see a review online.

CPU Benchmarks
To start things off if we compare the absolute highest end Intel Mac – a 2019 Mac Pro with a 28-core Intel Xeon W-3275M versus a 32-core M3 Ultra Mac Studio, the difference is astonishing. The Mac Pro can only muster roughly 42-44% of the new 32-core Mac Studio’s Multicore or Single core CPU performance, with the 28-core M3 Ultra not far behind at all. I decided to compare this versus the most powerful Intel Mac as it made the most sense. You may also go on the Geekbench website and compare the new Mac Studio to other various Macs including the ones you benched in your own collection.

We can conclude the new M3 Ultra chip is an absolute monster in terms of raw CPU performance, and thrashes the performance offered by any Mac at all in the Intel lineup. This Mac Studio is yet another nail in the coffin in the value of a 2019 Mac Pro further contributing toward it’s devaluation and becoming more affordable as a secondhand Mac.
Comparing against a maxed-out 2018 Mac mini i7
There is absolutely no competition no matter how fast and competent this Space Gray i7 2018 Mac mini feels. The M3 Ultra chip absolutely destroys an i7-8700B!
Metal GPU Comparison vs M2 Ultra Studio
Obviously, the M3 Ultra pulls ahead but how far ahead? A maxed M2 Ultra appears to be only 85% of the performance of a nearly maxed M3 ultra. See results here.
Metal Score vs a Mac Pro 2019 + 6900XT
It looks as though the M3 Ultra is more powerful than an AMD Radeon 6900XT, according to Geekbench.
M3 Ultra OpenCL
OpenCL performance looks superb on here.

Bonus: 32-core M3 Ultra versus Dual-Core T9500 Core 2 Duo 2007 iMac
We all know a 2007 iMac isn’t that fast, but how fast is it really compared to the new top-of-the-line Mac? We are now comparing a Mac which shipped with Mac OS X Tiger to one that isn’t even available to consumers until the week after this article is published. Prepare yourselves.
