![]() 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. However, if you look at each function separately, it's clear they are generally getting slower on newer OSes. Then OS 5.3.0 (relatively) crushed the times for the summation and list tests but fell behind a bit in BASIC performance.Īs 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. OS 5.0.0 is the champ for random numbers, graphing horizontal and vertical lines, and overall BASIC performance. I'd like to dig into the numbers a bit more though. 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. 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. 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. ![]() Each test, with the exception of prgmRAYTRSPR was completed 5 times then the times were averaged into the table above. ![]() The calculator was plugged in and fully charged the entire 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.
