The Apple M1 Ultra has been absolutely flattened by the Nvidia GeForce RTX 3090 in a synthetic benchmark and gaming comparison. This particular M1 Ultra, in a brand-new Apple Mac Studio, was the 20-core CPU/64-core GPU model, which is as high-end as it gets. But the RTX 3090 was able to score over +158% higher than the Apple silicon in one synthetic benchmark.
