Typical video editing is a combination of cpu, gpu and video encode hardware. Depends on the project. If the project applies a lot of affects it will tap the gpu more. If it is just a straight encode job then gpu won’t be as important and cpu and video encode units are more important. Overall for these tasks the ultra is faster.That graph feeds the myth that Apple is better at marketing than hardware manufacturing.
Has Apple published the software they used for that benchmark? Has anyone else been able to reproduce the benchmark on that graph?
Do those tasks use the GPU or another part of the SoC?
Photo editing is gpu and cpu heavy ( depends of the application.. affinity photo use a lot of gpu while photoshop only some functions are gpu enabled) and the ultra overall is faster at that than a high end cpu with rtx3090.
