https://www.hpmuseum.org/cgi-sys/cgiwrap/hpmuseum/articles.cgi?read=899
On 1980's Era models, it runs in about 90 minutes.
On a 2018 unit, it runs in less than a minute.
My 12CP finished the test (12c code) in 45 minutes, there only is 0.00 as result on the screen.
So it must be one of the "slow" 12CP?
The calculator has been made by Kinpo factory in the Philippines in (I believe) 2021.

There is a note in the 12CP program area about how to see the results of the 12CP version.
If you were using the 12C code, you have to RCL the memory registers.
RCL 0 through RCL 9, and RCL .0
or something similar.

OK thanks, I will try the RCL function.

Indeed, after the test finished all the 20 registers R0-R9 and R.0-R.9 are filled with numbers, not sure what they mean though.
RE: HP 12C Speed Test - ctrclckws - 12-30-2022 12:52 PM
Register 0 should have 3
Register 1 should have 1415926
Register 2 should have 5358979
And so on.
These are the digits of pi, in order.

The CPU speed is a lot difference between these two and let see how much difference.
01 ENTER
02 ENTER
03 +
04 GTO 03
1 ENTER 1 ENTER R/S for 1 minute R/S
Add two numbers 1+1 for 1 minute and compare the grand total result.
12C on Android 15796078 per 1 second = 263268
12C+ 75637 per 1 second = 1261
Gamo
HP-12C Platinum (4mhz cpu) : 2449 per second.

I tried the speed test described in this page :
https://www.hpmuseum.org/speed.htm
My result is 118, so 118 / 679 x 100 = 17.38% the HP 9100 speed.
