Unfortunately the GB10 is incredibly bandwith starved. You get 128gb ram, but only 270GB/s bandwidth. The M3 Ultra mac studio gets you 820GB/s. (The M4 max is at 410GB/s. I'm not aware of any workload that gets the GB10 to it's theoretical peakflops.

You can't get a 128GB M3 Ultra, it's also more expensive. For some workloads the Studio is better, for others the GB10.
