While the CPU and GPU are easy to quantify, they’re not the only important parts of Apple’s system-on-chips.
Other considerations: Neural Engine, video encoder, memory Apple is already years behind the competition there, and it’s not likely going to improve this year. While I think support for such a feature will have to happen sooner or later, it’s probably not going to arrive in the M2 line.

More importantly, serious high-end GPUs from AMD and Nvidia (and the coming Arc series from Intel) feature hardware accelerated ray tracing, which is absent from Apple’s GPUs so far. While such an increase in performance would bring the M2 Max in line with a fairly high-end mobile discrete GPU, it’s still not even half the performance of a top of the line desktop GPU. It is reasonable to expect that the figures provided here are probably a few percent lower than what Apple might squeeze out of the N4P process, and just as we saw greatly improved battery life in the A15-powered iPhone 13 phones, Apple may prioritize longevity in the MacBooks that use these chips. It all depends on Apple’s particular configuration, and battery life in particular is subject to a wide number of variables (like how power-efficient the display is, for example).įor our performance predictions here, we are not factoring in additional performance from manufacturing process improvements, as there is no way to realistically quantify what they might be. It’s not really known if this will translate into higher clock speeds, better battery life, or a little bit of both. TSMC claims that it can run up to 11 percent faster at the same power, or use 22 percent less power at the same performance. Improved manufacturing processīefore we get to the numbers, we should mention that it is expected for the M2 to be manufactured on TSMC’s N4P process, which is an enhanced form of the 5nm process on which the A14 and M1 were manufactured. The CPU cores will be swapped out for a 2-efficiency, 8-performance setup, and GPU cores will be quadrupled from the base M1 chip (for a total of 40). We’ll generate performance expectations with a doubling of that to 10 cores, which jibes with rumors about the M2’s configuration.įor the M2 Max, we assume the same scaling-up as from the M1 to M1 Max.

Note that the A15 actually has five GPU cores, with the fifth one enabled only in the iPhone 13 Pro models. In trying to predict the M2’s features and performance, we will operate on the assumption that it will follow a similar pattern, only this time with the A15: the same architecture with twice the high-performance cores and GPU cores.
