Like the M3 chip found in Apple's MacBook range, the M4 is based on 3-nanometer architecture and uses four performance cores, six efficiency cores and a 10-core GPU. While this might not be a revolution in performance over M3-based devices, Apple is making some big performance claims over older iPad models.

The company reckons the new chip will provide 1.5x better performance over the M2 chip, with 4x better GPU performance in certain tasks. Got a first-gen M1 iPad Pro? You can expect up to 10x faster performance in the new model. 

It's not just about straight-line speed, with Apple claiming significant boosts in power efficiency for better battery life. The chip also helps drive the new Tandem OLED technology that makes up both iPads' new Ultra Retina XDR displays.

No tech launch in 2024 would be complete without a mention of AI, and indeed the M4 chip promises better machine learning performance for AI-based tasks, although we expect to hear more about Apple's use of AI across all its platforms at WWDC in June. 

The M4 chip will come as standard in both sizes of the new iPad Pro, while the new iPad Air will come equipped with the older M2 processor.
