I keep reading the old forums and found some additional interesting reports.

In this post (Msg#18), Gene Wright suggests a small looping program to measure how fast the processor is.

Enter this looping program. Press:
shift P/R
shift CLPRGM
+
shift GTO 001
shift P/R
1 ENTER ENTER ENTER ENTER CLX
shift GTO 000
R/S and let it run for 60 seconds. The number in the display is the important one.


My calculator gives me a total count of about 1400.

IIRC, the latest 12C (non-platinum) scores about 70,000 on that test, so it seems these results could imply the current 12CP is running older code in an emulator, while the 12C is running code ported to the new processor.

Another interesting data point would be what a 15CLE does for the same benchmark. The 15's better program environment means slight changes to the simple test code, so results will be a bit off, but the gap between 1400 and 70000 is pretty large and it should be obvious which way that went (emulated or ported). Given the amazing speed claims I've read for the 15CLE, I would guess the latter, which also could explain the bugs related to Pausing.

Anyone got a 15CLE that's not still sealed, and willing to run this test?
