As anticipated, final night time’s Scary quick occasion ended up being all concerning the Mac, with the corporate unveiling the precise array of latest M3-powered Macs that latest rumors predicted.
In step with the late hour and the Halloween theme, the primary a part of Scary quick opened with an ominous nighttime sweep into Apple Park and a black-clad Tim Cook dinner rising from the misty shadows. The rest of the occasion maintained this motif, so clearly somebody at Apple determined to have some extra enjoyable with this one.
In contrast to previous unveilings of Apple silicon, the place the corporate launched its entry-level chips — the M1 and M2 — upfront of their extra highly effective pro-grade variations, this 12 months, Apple is debuting the whole M3 silicon household in a single fell swoop — with the doable exception of an M3 Extremely, which can nonetheless come down the street when Apple refreshes its Mac Studio and Mac Professional.
Nevertheless, the mainstream M-series chips had been all in attendance, with Apple introducing the baseline M3 accompanied by the M3 Professional and M3 Max.
The New M3 Chip Household
As Tim Cook dinner handed the occasion over to Johny Srouji, the digital camera swept right into a deep and darkish underground facility the place Apple’s chief chip designer and Senior VP of {Hardware} Applied sciences got here out of the shadows right into a a lot crypt-like tech lab, opening with an previous B-movie model “Welcome to my lab” tagline.
Srouji highlighted the same old advantages of Apple silicon, together with the “industry-leading energy effectivity” and “state-of-the-art designs,” earlier than specializing in what the brand new M3 era brings to the desk.
Tonight we’re doing one thing we haven’t finished earlier than, as we convey our newest applied sciences to a broader set of customers extra quickly than ever. We’re launching the subsequent era of Apple silicon for the Mac by debuting three breakthrough chips on the similar time.

Srouji additionally touched on the unprecedented simultaneous launch of all three courses of M3 chips to cowl the whole vary of its prospects’ wants.
Just like the A17 Professional, all the M3 chips have been fabricated utilizing a brand new 3 nanometer (3nm) course of, making them the primary chips to be constructed for a private pc utilizing this expertise, which permits for transistors so tiny you may match two million of them within the cross-section of a human hair.
The result’s that Apple’s strongest M3 Max chip now contains a staggering 96 billion transistors.
Contemplating the GPU-focused enhancements on the iPhone 15 Professional’s A17 Professional chip, it’s not a giant shock that Apple is doing the identical with its new M3 sequence, the place Srouji notes the “largest advance is within the GPU,” which takes “the biggest leap ahead in graphics structure ever for Apple silicon.”
This consists of comparable hardware-accelerated ray tracing options to these discovered on the A17 Professional, which fashions the bodily properties of sunshine because it interacts with a scene so video games can render extra correct shadow and reflection to create extra sensible environments. That is joined by hardware-accelerated mesh shading and a brand new graphics structure that delivers rendering efficiency that’s 2.5 instances quicker than the M1 household of chips or 1.8 instances quicker than the M2.
Extra important for builders is that Apple is debuting an industry-first Dynamic Caching function within the GPU that gives significantly better reminiscence allocation. As Srouji explains, different GPUs require software program builders to find out the quantity of GPU reminiscence that their apps will want at compile-time; this makes every app require a hard and fast quantity of graphics reminiscence primarily based on the necessities of the app’s most demanding activity, leaving that reminiscence allotted even when it’s not getting used.
With Dynamic Caching, graphics reminiscence will likely be allotted by the M3 silicon in real-time, which suggests solely the precise quantity of reminiscence wanted is used for every activity at any given time. Based on Srouji, this may dramatically enhance the common utilization of the GPU, considerably enhancing efficiency for essentially the most demanding apps and video games.
The M3 chips are additionally including a brand new AV1 decode engine to allow extra power-efficient playback from YouTube, Netflix, and different streaming providers.
As with its earlier advances in Apple silicon, Apple has additionally managed to make these efficiency boosts with none compromises on energy effectivity, with the M3 CPU delivering the identical efficiency because the main 12-core PC laptop computer chip at solely one-quarter of the facility — a feat which additionally permits Apple silicon to carry out simply as nicely on battery because it does when plugged in.
All of Apple’s M3 chips, from the bottom M3 to the M3 Max, achieve the identical CPU and GPU enhancements. It’s the variety of cores in every and the unified reminiscence that symbolize essentially the most elementary variations between them.
With our scalable structure, we tailor every M-Sequence chip for various consumer must ship best-in-class options to each consumer.

The usual M3 continues to supply the identical 8-core CPU and 10-core GPU as its M2 predecessor, with 4 efficiency and 4 effectivity cores. Nevertheless, the efficiency of every core has naturally been improved, significantly on the GPU facet, leading to efficiency as much as 65% quicker than the M1 chip. It continues to assist as much as 24GB of unified reminiscence, so it’s the GPU enhancements which might be the true game-changers right here.
The M3 Professional equally options the identical 12-core CPU architectures because the M2 Professional — six efficiency and 6 effectivity cores — however the GPU drops to an 18-core configuration, whereas the unified reminiscence can now go as much as 36GB. Once more, the CPU cores are undoubtedly quicker than these within the M2, and the GPU structure has improved to the purpose the place it nonetheless beats out the M2 Professional regardless of having one much less core. Nonetheless, it’s telling that Apple solely lists it as 10 % quicker in GPU efficiency and 20 % quicker in CPU efficiency.
It’s in the end the M3 Max that will get essentially the most important enhance right here, with a 16-core CPU (up from 12 cores), which is tuned extra closely towards the efficiency facet — 12 efficiency cores and solely 4 effectivity cores. That places the CPU facet at 80% quicker than the M1 Max and 50% quicker than the M2 Max. The GPU additionally will increase to a 40-core configuration that’s 20% quicker than the M2 Max, and the chip now helps as much as 128GB of unified reminiscence — a degree that was beforehand the unique area of the M2 Extremely. This additionally ends in 92 billion transistors — a 50% enhance within the transistor depend over the M2 Max.
