So it must be one of the "slow" 12CP? The calculator has been made by Kinpo factory in the Philippines in (I believe) 2021. HP-12C Gold / HP-12C Platinum |

RE: HP 12C Speed Test
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. |

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
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. |

RE: HP 12C Speed Test
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. HP-12C Gold / HP-12C Platinum |

RE: HP 12C Speed Test
Considering that ‘2-liner’ loop:
1; Enter; Enter; Enter; 01 + 02. GoTo.01 and some results by: (08-23-2017 08:18 PM)rprosperi Wrote: Here are some results, using the same 2-liner, from past testing: I tested some of my HP 12C calculators: HP 12C (sn 3534S03xxx Singapore, 3x LR44 CPU HP 1RR2-0001) = 507/min HP 12C (1x CR2032 - CPU Agilent 2AF1-0002) = 534/min HP 12C Prestige (sn CNA 6430xxx Brazil =CP; 1x CR2023 - CPU epoxi_on_pcb “BF123-11-3”) = 1458/min HP 12C + (sn CNA 1410Pxx; 2x CR2032 - didn’t need to open; CPU not checked) = 80260/min And for other HP machines or RPN based, using << LBL 0; +; GoTo 0 >> HP 15C (sn 2826B31xxx Brazil, 3x LR44, CPU & IC: 1LH1-0302 & 1LQ9-0325) = 303/min HP 42S (sn 3022B77xxx) = 2196/min HP 35s (sn CNA 9320xxxx;) = 2801/min WP 34S (from HP 20b sn CNG82801xxx) = 134702/min (2245/sec) DM 42S (sn 8680; default mode) = 374799/min (6247/sec) Finally, using the Hardware-based SUM function (inf: 1; sup: Y ; func: 1) on some popular Scientific calculators, just to provide a loose comparative figure: Sharp EL-W516X (Y = 5000) @ 38sec = 7890/min Casio FX-115ES (Y = 5000) @ 42sec = 7140/min Casio FX-991LAX (Y = 30000) @ 52sec = 34600/min Casio FX-991ES+ 2nd.Ed. (Y = 10000) @ 28sec = 21400/min Untested (yet): I have a HP 20b unmodified and a HP 17bii+, which I didn’t think how to compare with this simple loop, in a fair way. Suggestions are appreciated. I have an HP 41CV, but without batteries to test. I and one HP48G+ and two HP 50G, but didn’t test them as they are much more powerful and RPL, (another class of HW) and looping could be implemented on different ways; however, if you suggest some reference program/function to check, I would supplement the testing info. In overall, it was fun to test. Greetings from Rio de Janeiro! Euthymios “E.J.E.” |
