> For example the Nintendo Switch had very mediocre system performance

Nintendo Switch had the most powerful GPU of any mobile device released at its time. Furthermore it has 4 GB of RAM. Just the Cortex A-57 CPU wasn’t bleeding edge any more, having been replaced by the Cortex A-72 by the time of the Switch with a higher IPC of 16%. It was a well balanced system.

You might be mistaken because mobile CPU performance grew in an unparalleled explosive fashion, and the Cortex A-72 was already replaced by the A-73, A-74, A-75, A-76, A-77, A-78, and A-710 by now. But this is unfair to a system where its design was frozen already 6 years ago.

It just means that, if a successor Switch is built the same way, and a Cortex A-78 is used, its CPU would have ca 2.6x IPC. If it ran at twice the clock speed, its CPU performance would be 5.2x.

You’re being unfair because CPUs grew so much.
