Well, we all know what happened: Apple humiliated Mac Pro 7.1.
Wrong adjective. More like committed fratricide on the Mac Pro 2019 (7,1). A substantive chunk of legacy Mac Pro buyers will be pulled out from the " Mac Pro 2019" potential market. ( cannibalization of that sub-market. ) However, the Mac Pro 7,1 also left a huge chunk of legacy Mac Pro buyer on the curb ( or under the bus if really needed to upgrade) by increasing the entry MP price by 100%. The Mac Pro did nothing for those folks in the 2.5-4K price zone. The Studio at least does something for them.
This isn't really new. The MBP 16" has enough horsepower for many folks who would have been in the "Mac Pro computational requirements" space in 2006-2012 era.
Apple did carefully tap dance around any claims that the Ultra 'crushes" a duo W6800X or quad W6800X performance. Apple said in the keynote that the 16 core and W5700 were the most popular CPU and GPU for the Mac Pro 7,1. So there is very high overlap in target market coverage for those who just have CPU and/or GPU computational primary issues.
There is a narrower subsegment they have left "on the floor" for an upgraded Mac Pro to cover. That is mostly not in CPU/GPU benchmark scores.
The MacBook Air, MacBook Pro 13" two port , Mini , iMac 24" all overlap in M1 usage.
The MBP 14 and 16 and Studio Max overlap in M1 Max usage.
The Studio and upgraded Mac Pro will very likely overlap in "Ultra" class. What probably will see in a next gen Ultra that enables some PCI-e slots provisioning but next to zero CPU/GPU performance gap from the Studio. The Mac Pro and Studio will share that.
The stratification between Mac products isn't going to be as high as it was under Intel CPU either. Intel had an order of magnitude more CPUs to pick from than anything Apple is going to create.
Finally it is a 2018-19 era system foundation. Kicking sand in the face of an 3 year tech really isn't much of humiliation. More avoiding real competitive contemporaries. Pulled in some cherry picked 3090 benchmark that had to be a cross platform comparison since doesn't support Nvidia drivers anymore. They didn't go out and get a BoXX W-3300 workstation and a dual 3090 can compare notes on top end render times.
The baseline of all of Apple comparisons made were against the top end BTO configuration of the iMac (and again multiple years ago since update) , not the Mac Pro.
A "cheap" Mac Studio is more powerful than the ultra expensive Mac Pro 7.1. And this is happening only two years after the release of Mac Pro 7.1.
19 + 2 = 21 . It is 22. And the 2019 was not full of bleeding edge tech when launched. ( W-3300 was super late. The base graphics was a 580X, relatively old PCI-e v3 , etc. )
