Just recently, Apple somewhat stunned the industry with the introduction of its refreshed Mac Studio with the M4 Max and M3 Ultra SoCs. For whatever reason, the Cupertino giant decided to spec its most expensive Mac desktop with an Ultra SoC that is based on an older generation, M3, instead of the newer M4 family. However, the M3 Max, which the M3 Ultra is based on, was no slouch, indicating that the M3 Ultra will likely boast impressive performance. However, if a collection of recent benchmark runs are anything to go by, it appears that the M3 Ultra is a tad too closely matched with the M4 Max in CPU performance, which makes the $2000 premium between the two SoCs rather difficult to digest. Needless to say, a single benchmark is hardly representative of real-world performance, so accept this information with a grain of salt.

According to the recently spotted Geekbench result, the M3 Ultra managed a single-core score of 3,221, which is roughly 18% slower than the M4 Max. In multicore performance, one might expect the 32-core M3 Ultra to sweep the floor with the 16-core M4 Max, but that is not quite the case. With a score of 27,749, the M3 Ultra leads the M4 Max by an abysmal 8%. Of course, these are early runs, which may suggest that future scores will likely be higher. However, it is clear as day that the M3 Ultra and the M4 Max, at least in terms of CPU performance, will be close together in multithreaded performance, with the M4 Max continuing to be substantially faster than the far more expensive M3 Ultra variant in single-threaded performance. It does appear that the primary selling point for the M3 Ultra-equipped Mac Studio will be the massive 80-core GPU and up to 512 GB of unified memory shared by the CPU and the GPU, which should come in handy for running massive LLMs locally and other niche workloads.
