I don't know why people even consider buying Macs for desktop use, especially when studios require GPU intensive work. The performance of the Titan V, a card released in 2017 (almost 6 years ago), is 14.14% higher than that of the M2 Ultra according to Geekbench's OpenCL compute benchmarks. That's right, a 6 year old card trashes the M2 Ultra by about 15%. Just to be clear, some people use multiple 4090s for their work scores 2.97 times the M2 ultra on the benchmark (3 times the compute power), so that shows how bad the M2 Ultra is. The benefit of Apple Silicon is its ridiculous efficiency, which is why I have an M2 Macbook. The battery life is better than any Windows laptop.
But, I would never every buy a Mac desktop. Desktops are about power and the Mac doesn't cut it. Unless you use desperately need Final Cut Pro and Logic Pro, there's no reason to use it. Pros generally use Premiere Pro, After Effects, Pro Tools, Ableton, etc. The two softwares (with many Windows alternatives) themselves can't justify the weak hardware especially if you're big studio that requires a lot of compute. Then there's the reverse of the previous scenario, which is that a lot of pro software isn't available for Mac, which adds to the problem. Apple Silicon Macs can't Bootcamp Windows either since they aren't x86. Nvidia Cuda cores also have a lot of software designed specifically for it too, which can't be emulated on the Mac.
Apple's CPU is ridiculously fast and Geekbench results show that the single core scores of the M2 Ultra are equal to the 13900K and multi-core scores are equal to the more powerful flagship 13900KS (coincidence or by design, who knows). For studio purposes, the multi-core score is more important since tasks are more parallelisable than say, gaming. The M2 Ultra is basically a 13900KS and a GPU in between the 4060 Ti and 4060 combined into one. Such a bad combo. But let me show you how efficient it is. The M2 Ultra has a TDP of 60 watts. The 13900KS has a TDP of 150 Watts. The 4060Ti is 160 Watts and the 4060 is 115 watts. Say a weighted average of about 150 watts for the GPU. The combined TDP is 300 watts. The M2 Ultra doesn't just include the CPU and GPU, but a bunch of other stuff including the RAM, controllers, etc. We'll say a combined total of 30 watts for those extra components for a normal Windows desktop. The M2 Ultra's TDP is 90 watts for the higher 76 core GPU variant since nobody is getting the default one.
That means that Apple is achieving the same compute as its Intel + Nvidia equivalent using 27% of the power, which is insane and matches Apple's own claims of 1/4th the power for the same compute. Insane is an understatement, frankly. But despite how ludicrous this is, nobody cares because desktops are about pure power, whereas phones and laptops are not.
