iPad Pro The M2 chip has 50% higher unified memory bandwidth compared to M1

[Retskrad]

The unified memory bandwidth of all the M-series chips:

- M1: 66.67GB/s
- M2: 100GB/s
- M1 Pro: 200GB/s
- M1 Max: 400GB/s
- M1 Ultra: 800GB/s

The 2023 MacBook Pros are also rumored to have even faster memory bandwidth compared to 2021 MacBooks Pro’s.

The question is, which app or task on the M2 iPad Pro can take advantage of higher unified memory bandwidth?

I just spotted the cleverly hidden agenda behind this question

The question is, which app or task on the M2 iPad Pro can take advantage of higher unified memory bandwidth?

For instance, when you do a long screen recording (1h+), on previous iPad pros the pros it took more than double the time to process the recording and saving it to Photos. On the M1 the time was similar to the 2018, tested by myself. On the new M2 iPad Pro, a screen recording that usually took almost two minutes to be processed (1m44s) on older devices, now it just takes 40 seconds. Amazing.

My guess is, that screen recordings are being stored on RAM, and when the recording is finished, it gets processed and transferred to the storage. And there you’re seeing the benefits of the faster bandwidth.

I hope more and more developers update their apps to take advantage of the higher memory bandwidth.
