NEW YORK—Not one of the new Macs that Apple is saying at its “Scary Quick” product occasion immediately look very completely different from those they’re changing on the surface, however the inside is one other story. That is the primary batch of Macs to incorporate Apple’s next-generation M3-series chips, and in contrast to previous years, Apple is introducing a number of M3 efficiency tiers all on the identical time.
The M3, M3 Professional, and M3 Max all share the identical underlying CPU and GPU architectures, the identical ones used within the iPhone 15 Professional’s A17 Professional chip. Additionally just like the A17 Professional, all M3 chips are manufactured utilizing a brand new 3 nm course of from Taiwan Semiconductor (TSMC). Let’s dive into the whole lot we all know in regards to the M3 household’s capabilities, plus the variations between every efficiency tier.
Meet the Apple M3 household
-
Apple prioritized comparisons to the M1 technology, which is extra more likely to be related for upgraders. However in context with the M2 numbers, M3 seems like a typical year-over-year improve.
Apple -
The effectivity cores enhance quite a bit over M1—however M2 did, too.
Apple -
Everybody’s favourite type of chart! Apple says an M3 can match an M1’s efficiency at simply half the ability, although peak efficiency will seemingly be extra related for most individuals.
Apple -
The size is analogous for the GPU, although efficiency improves a bit extra.
Apple -
Apple relishes the comparisons with its ex-partner Intel, whose i7-1360P doesn’t come off effectively right here. Intel’s next-gen Meteor Lake chips are proper across the nook, however it is a large gap to dig out of.
Apple -
Intel’s built-in GPU efficiency leaves quite a bit to be desired.
Apple -
The Neural Engine will present even sooner acceleration for supported AI and ML workloads, although enhancements over the M2 are comparatively modest.

Apple says that the efficiency cores in any given M3 processor can run as much as 30 % sooner than the M1’s efficiency cores, and that the effectivity cores are as much as 50 % sooner. Most of Apple’s direct efficiency comparisons had been to the M1 technology, which is beneficial insofar as M2 Mac homeowners aren’t more likely to need to spring for M3, however it has the added advertising and marketing profit of constructing the efficiency will increase sound bigger than they’re.
To place these numbers in context, the M2’s P-cores had been already between 10 and 20 % sooner than the M1’s, relying on the chip. Isolating the E-cores in benchmarks is a little more troublesome, however Apple says that the M3 is as much as 35 % sooner than the M1 at peak energy. Apple stated the M2 was about 18 % sooner than M1.
| CPU P/E-cores (max) | GPU cores (max) | Most RAM | |
|---|---|---|---|
| M1 | 4P/4E | 8 | 16GB |
| M2 | 4P/4E | 10 | 24GB |
| M3 | 4P/4E | 10 | 24GB |
| M1 Professional | 8P/2E | 8P/8E | 32GB |
| M2 Professional | 8P/4E | 19 | 32GB |
| M3 Professional | 6P/6E | 18 | 36GB |
| M1 Max | 8P/2E | 32 | 64GB |
| M2 Max | 8P/4E | 38 | 96GB |
| M3 Max | 12P/4E | 40 | 128GB |
The M3’s GPU can also be based mostly on the identical structure because the A17 Professional, which implies that all M3 Macs are choosing up hardware-accelerated ray-tracing help like what you discover in newer Nvidia GeForce and AMD Radeon GPUs. As in desktop PCs, enabling ray tracing in most video games and apps goes to return with a efficiency penalty, which can make it extra usable on the M3 Professional and Max than it’s within the primary M3, however each GPU within the household a minimum of helps the potential.
Different {hardware} options added to the M3 GPU embrace “Dynamic Caching,” which claims to allocate “solely the precise quantity of reminiscence wanted… for a given process,” permitting extra duties to make the most of the GPU at a given time. Like DirectX 12 Final GPUs, the M3 GPU additionally helps hardware-accelerated mesh shading, helpful for rendering scenes that use a complete lot of small objects.
Except for new {hardware} options, Apple says that peak GPU efficiency for the M3 collection is as much as 65 % sooner than M1’s, although as with the CPU efficiency it will seemingly range based mostly on which chips you are evaluating. In our checks, the varied M2-series GPUs are usually between 25 and 30 % sooner than their M1 equivalents, so the year-over-year efficiency will increase from M1 to M2 to M3 are pretty even. Apple says that the M3’s rendering efficiency is as much as 2.5 instances sooner than the M1 for workloads that reap the benefits of the brand new {hardware} acceleration options.
Lastly, the media engine within the M3 collection helps hardware-accelerated decoding for AV1 video streams. Newer PC GPUs additionally help hardware-accelerated encoding, however it’s nonetheless a reasonably area of interest function with comparatively restricted usefulness for residence customers past high-resolution video broadcasting. Nonetheless, it is one thing that almost all trendy built-in PC GPUs help (or will help very quickly), so it is too dangerous to not see it right here.
