Apple says the CPU is up to 50 percent faster than the M2 found in the previous iPad Pro, which means it’s somewhere around 20-25 percent faster than the CPU in the M3. The GPU is said to be up to four times faster than that in the M2, though that might be a “best case” scenario that uses lots of ray tracing. The Neural Engine is the fastest in any Apple product, but just barely—the A17 Pro in the iPhone 15 Pro can do 35 trillion operations per second, according to Apple.

Apple says the M4 has a memory bandwidth of 120GB/sec, up from 100GB/sec in both the M2 and M3. There’s also a new display engine to handle the “Tandem OLED” display and updated video processing with support for H.264, HEVC, ProRes, and AV1.

When it comes to power efficiency, Apple says M4 uses no more power than the M2 and can deliver the same performance using only half the power, and the same performance as a thin and light PC with one-fourth the power (Apple used an ASUS Zenbook 14 OLED with Core Ultra 7 155H for that comparison).

In iPad Pro models with 256GB or 512GB of storage, the M4 will have 8GB of RAM. In those with 1TB or 2TB of storage, it will have 16GB. So that remains unchanged from the M2.

It’s not clear when the M4 will make its way to the Mac, but with the M3 MacBook Air only arriving in March and the Pro models making their debut in November, it’s likely the first laptops won’t roll out until later this year. However, it’s possible that the Mac mini, Studio, and Pro, which are still using M2 chips, get an M4 refresh sooner than that.
