As you all know, as technology gets updates with more features, that device typically starts slowing down. I was wondering, is TI doing this to our calculator's too? That's why I set up a series of tests and ran them from OS 5.0.0 to 5.4.0. Each one tests a specific function of the calculator. You can see a description of each test and the full code for each one down below.
Anyways, enjoy the chart:
green is the best time
and red is the worst time
!
Each test was performed from the RAM, on the same calculator (revision pre-A), in the same order, and after a full mem clear. The calculator was plugged in and fully charged the entire time. Each test, with the exception of prgmRAYTRSPR was completed 5 times then the times were averaged into the table above. I only ran prgmRAYTRSPR once because it takes over 30 minutes per run and ain't nobody got time to do that 5 times over! I have yet to retest OSes under 5.3.0 for new prgmRAYTRSPR times.
Overall it seems if you want the best BASIC performance, then OS 5.0.0 or OS 5.3.1 is the way to go. However, if you just care about the speed of specific functions, then you can't go wrong with OS 5.1.x or 5.2.1.
I'd like to dig into the numbers a bit more though.
- OS 5.0.0 is the champ for random numbers, graphing horizontal and vertical lines, and overall BASIC performance. Then OS 5.3.0 (relatively) crushed the times for the summation and list tests but fell behind a bit in BASIC performance.
As you can see by the graph, the only reason the newer OSes had good total scores was because the raytracing program was such a huge factor in this test. However, if you look at each function separately, it's clear they are generally getting slower on newer OSes.
TI changed something for the better between OS 5.0.0 and OS 5.1.0 that made list sorting almost 9x faster on newer OSes! Even for numbers that weren't 0s.
TI also changed something for the worse between OS 5.2.1 and OS 5.3.0 because every OS newer than 5.2.1 is typically 3 seconds slower.
Here are the tests I performed, you can get prgmTIMER here.

So there you go, personally I think OS 5.3.0 has the best performance to match its features (Asm84CEprgm token, yay!). Let me know if you have any questions or concerns!
