Apple’s latest M3 Pro chip in the new 14-inch and 16-inch MacBook Pro has 25% less memory bandwidth than the M1 Pro and M2 Pro chips used in equivalent models from the two previous generations. From a report: Based on the latest 3-nanometer technology and featuring all-new GPU architecture, the M3 series of chips is said to represent the fastest and most power-efficient evolution of Apple silicon thus far. For example, the 14-inch and 16-inch MacBook Pro with M3 Pro chip is up to 40% faster than the 16-inch model with M1 Pro, according to Apple. <\/p>\n
However, looking at Apple’s own hardware specifications, the M3 Pro system on a chip (SoC) features 150GB\/s memory bandwidth, compared to 200GB\/s on the earlier M1 Pro and M2 Pro. As for the M3 Max, Apple says it is capable of “up to 400GB\/s.” This wording is because the less pricey scaled-down M3 Max with 14-core CPU and 30-core GPU has only 300GB\/s of memory bandwidth, whereas the equivalent scaled-down M2 Max with 12-core CPU and 30-core GPU featured 400GB\/s bandwidth, just like its more powerful 12-core CPU, 38-core GPU version. <\/p>\n
Notably, Apple has also changed the core ratios of the higher-tier M3 Pro chip compared to its direct predecessor. The M3 Pro with 12-core CPU has 6 performance cores (versus 8 performance cores on the 12-core M2 Pro) and 6 efficiency cores (versus 4 efficiency cores on the 12-core M2 Pro), while the GPU has 18 cores (versus 19 on the equivalent M2 Pro chip).<\/p>\n
