On raw performance might, the M4 really does live up to Apple’s promises, should deliver. Single core is up about 20% compared to all M3 chips and more than 40% compared to M2. The generational computational leap from the previous M2 iPad Pro is at least a 42% jump on single-core and multi-core.
In Geekbench, yes. From other reporting I’ve seen the major improvements here are from Scalable Matrix Extensions being on the M4, which Geekbench supports. Real world performance of which would be limited to certain scenarios and require application support for SME.
