"While the M3 Pro's performance was disappointing overall compared to the M2 Pro and even the M1 Pro, the same can't be said of the M3 Max. Using Geekbench, the M3 Max is about as fast as the M2 Ultra, earning a single-core score of 3217 and a multi-core score of 21597. The M2 Max has a single-core score of 2737 and a multi-core score of 14503, and the difference is even more pronounced compared to the 2021 M1 Max, the first 16-inch MacBook Pro to get an Apple silicon chip. The M1 Max has a single-core score of 2379 and a multi-core score of 12206."
