Apple unveiled its new range of chips during its Scary Fast event which, as expected, consists of the base M3, the M3 Pro and the M3 Max. We already know some of the figures associated with the 3nm chips thanks to Mark Gurman of Bloomberg, but the real meat and potatoes look to lie in the GPU of these chips.
The iPhone maker claims that these provide the “largest leap forward in graphics architecture ever in Apple Silicon”. A lot of this has to do with the tech that the company calls Dynamic Caching. What this does is letting hardware allocate the amount of graphics memory in real time for upcoming tasks. This is opposed to just reserving the same amount of memory based on the most demanding task which leaves a lot of available performance unused. The company also claims that this is an industry-first.
Beyond Dynamic Caching, the M3 family of chips also get features like hardware-accelerated mesh shading and ray tracing. Not too surprising, considering the graphics trend in the past few years. All this does mean that new Macs and MacBooks with the new chips will be getting a massive jump in graphical performance. This theoretically includes gaming, though the platform needs access to more games first. Other advancements outside of GPU include an improved Neural Engine, as well as the inclusion of an AV1 decoder.
On the number of cores, Apple has announced that the base model M3 comes with four performance and four efficiency CPU cores, as well as 10 GPU cores, confirming Gurman’s recent claim. Ditto the M3 Pro, we’re looking at six of both performance and efficiency CPU cores and 18 GPU cores, but no mention of a higher spec version during the event. Likewise with the M3 Max, the company showcased a version with 12 performance cores and four efficiency cores for the CPU, and 40 for the GPU, with no mention of the 32-core version.
As for which devices are getting these new M3 chips, Apple says that the 24-inch iMac will be getting the base model chip as part of its refresh. The 14- and 16-inch MacBook Pro models will also be getting refreshed models sporting the M3 and M3 Pro, with M3 Max models coming later.
