Using the same input as stated on This Video, it took around 9 seconds do give the answer (that´s including a '~1sec delay' between pressing the IRR button and the screen switch to 'Running').
That´s between a 25th anniversary (~10 sec) and the Prestige (~8 sec) editions.

At work I had been thinking about doing a speed test - good job!

My only worry about calculating the IRR is that it could be at least partly firmware-dependent.

So calling on a 2017 thread:

Test: 1 ENTER ENTER ENTER R/S run for 1 minute R/S

1+1+1+ .. .......... +1 for 1 minute

Approximate Result

12C+ 79029 -------> 1317 per second
12C App 12491137 ---> 208186 per second

1985 12C: 499
1992 12C: 518
2003 12C (1x2032): 511
Early (silver, no undo) 12CP: 3150
Later (silver, w/ undo) 12CP: 1424
25th Ann 12CP: 1446
30th Ann 12C: 72,684
HP-25C: 535

Nothing surprising, though the slowdown in the 2nd-gen 12CP is interesting.

And my results:

HP-12c Platinum with undo: 1432
HP-12c Rogue: 44'786.

This is interesting - the 12c+ and more recent 12c using the two ARM processors seem to be doing at least 60% faster than the Rogue 12c. And those are running a NUT emulator, which makes me think the rogue 12c isn't running either of those ARM processors.
