Apple has finally unveiled its new family of Apple Silicon chipsets at the 'Let Loose' event. The Apple M4 has been introduced with the new OLED iPad Pro. The iPad Pro range has jumped straight from the Apple M2 to the Apple M4. So in this article we compare Apple M4 and M2 to evaluate their performance difference in CPU, GPU and Neural Engine. We've also discussed memory bandwidth and other AI-related improvements on the M4. With that said, let's begin.

We have updated the frequency specification of Apple M4 based on the recently revealed Geekbench listing. Additionally, we have added the Geekbench score of the Apple M4 chipset to our analysis.

Here is the specification comparison between Apple M4 and M2. Take a look to understand the difference between the two control circuits.

Starting with the CPU first, the Apple M4 is developed on TSMC's 2nd generation 3nm process node which is said to be more efficient. It holds a whopping 28 billion transistors. The Apple M4 CPU for iPad Pro comes in two configurations: 9 CPU cores and 10 CPU cores.
