Does m1 chip really made iPad fast

Yes, but the I feel like the iPad is already fast enough that the M1 chip speed is barely noticeable. We need to give the developers time to create and update their apps to fully utilize the chip's power.

I don't have mine yet, but press reports indicate the M1 iPad Pro is significantly faster at some processor- or graphics-intensive tasks than earlier iPads. Some functions were already so fast that it would be hard to notice the improvement on the M1.

The new 2021 iPad Pros get even more internal processing RAM. At least 8 GBs now.

That is double of what it is in my current, much older iPad Pro, which is only 4 GBs of RAM.

My new 2021 iPad Pro is also STILL on back order and I have not received any more delivery updates from Apple, yet.

My delivery date is still sometime mid-July.
