Geekbench for the 3 is 326 single-core/559 multi-core vs the 4’s 803 single/1250 multi.
The 4 had a 1.4 GHz A6X vs the 3’s 1 GHx A5X. The 4 was the first big iPad with the Lightning connector.
My iPad 3 was always a slow pig of a thing.

I bought a basic 16 GB iPad Mini (512 MB RAM) a few months after buying a 32 GB iPad 3 - aka “The New iPad” - which had 1 GB of RAM.

All that extra RAM was used up by the 3’s retina display. Both had 1 GHz processors, an A5 in the Mini & an A5X in the 3.

Booting into Linux is impossible on Apple hardware that uses the T2 chip.

You’ve got your wires crossed there. ’twas the iPad 2 and original iPad Minis that had 512 MB of RAM.

Alledgedly they go bonkers over KFC at Christmas.

Inflatable cheese?

Turns out the new Retina MacBook Air isn’t such a low performer as its low-power processor would suggest. Beats the 12-in base model MacBook & previous Air by a nice margain and isn’t much behind the 2017 13-in TouchBar-free MacBook Pro.

10 km down the road is where 90% of Australia’s asparagus is grown. The very best cuts are exported to Japan, arriving in little wooden boxes less than 24 hours after picking.
