Does anyone know if the i41CX on max speed is faster than the 41CL on Turbo50? And how does the V41 emulator compare?

Thank you for any info!

I was curious and did a little test, and let this counter run for about 10 seconds:

LBL 01
1
+
GTO 01

a few results:

DM41X slow: ca. 90
DM41X fast: ca. 1100
i41cx on iPad Mini 2: ca. 140
v41 max. Turbo on my PC: ca. 50000

go41cx (Pixel 2XL) x1: ca. 90
go41cx: x8 ca. 1000
go41cx: x32 ca. 6000
go41cx: max ca. 50000

This is a bit of an apple (hardware) to orange (software) comparison. FWIW

41CL, Turbo 50: 1,158. Timing subject to finger lag...

Thank you for the feedback, seems the 41CL is actually about 10x faster than i41CX (who’s speed iirc is not hardware dependent actually, ie it runs the same on all iPad / iPhone versions, but I might be wrong there). That is indeed interesting.

Wish I had a PC as it seems the V41 is yet again at least an order of magnitude faster.

Thank you for these numbers!

it appears to be so, i41cx on an original iPad also counts to about 140 in 10 sec.

2 more values:

py41 (Prime G2) slow: approx. 60
py41 (Prime G2) fast: approx. 300

Here are some numbers using ...

First, the usual speed test :-) is LBL 01 + GTO 01 with the stack containing ones and a zero in X.

Second, here are my results:

i41CX+ in fast mode (iPhone 11) : 3705 counts in a minute.

DM-41X in fast mode (on battery): 12,895 counts in one minute. <-----------

DM-41X in fast mode (on USB): 40,301 counts in one minute. <-------------

Standard HP-41C (from PPC Journal issue where HP-41C was introduced), same program: 1041 counts in a minute.
