MPG tested the 2020 iMac 5K 3.6 GHz Intel Core i9 10-core / 128GB / 2TB / Radeon 5700. Smart move: buy with 8GB memory, then add 64GB or 128GB OWC memory to save a ton on memory cost (same memory as 2019 iMac 5K).
Adobe Camera Raw Enhance Details is a GPU-intensive task that uses 4-5 CPU cores as well. But the GPU utilization varies oddly across machines, as the screen shots show further below.
With the huge cost (over $2000) of the Vega II video card in the 2019 Mac Pro, the 28-core 2019 Mac Pro with Vega II video card gives a pathetic result in terms of cost/value.
But see the GPU utilization screen shots below...
GPU and CPU utilization
It goes to show that a “faster” GPU is only as fast as the application and operating system allow it to be utilized.
