M2 Ultra is on the desktop charts.

At that level its competing on efficiency and capped by power consumption. It can't reach 5 GHz with only 80 watts for all cores. Running at 3.5 GHz. The Intel and AMD CPUs need hundreds of watts and reach 5 GHz+. It's a tradeoff for efficiency. Different design decisions. Different tradeoffs. Not exactly competing in the same market segments.

Mac Pro is often used for video editing. The M2 Ultra has hardware acceleration for video encoding/decoding that would need a separate accelerator card on Intel or AMD to match: "M2 Ultra can support up to 22 streams of 8K ProRes 422 video playback"
