Benchmarking every TI-84 Plus CE OS! [5.0.0-5.4.0]

Hey, this is cross post from Cemetech, I thought you guys might find it interesting though!

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.

Here are the tests I performed, you can get prgmTIMER here.
ABENCH (runs every benchmark and stores the results into a list)

Code: Select all: SetUpEditor L₆ 9→dim(L₆ prgmT01RAND Ans→L₆(1 prgmT02GRAPH Ans→L₆(2 prgmT03GRAPH Ans→L₆(3 prgmT04SUM Ans→L₆(4 prgmT05LIST Ans→L₆(5 prgmT06LIST Ans→L₆(6 prgmT07LIST Ans→L₆(7 L₆

T01RAND (random integer test)

Code: Select all: 0→B For(A,1,5 Asm(prgmTIMER rand(100 Asm(prgmTIMER Ans+B→B End B/5

T02GRAPH (Horizontal line test)

Code: Select all: 0→W For(A,1,5 Asm(prgmTIMER ClrDraw For(B,Ymax,Ymin,Y Horizontal B End Asm(prgmTIMER Ans+W→W End W/5

T03GRAPH (vertical line test)

Code: Select all: 0→W For(A,1,5 Asm(prgmTIMER ClrDraw For(B,Xmax,Xmin,X Vertical B End Asm(prgmTIMER Ans+W→W End W/5

T04SUM (summation test)

Code: Select all: 0→W For(A,1,5 Asm(prgmTIMER Σ(X²,X,0,1000 Asm(prgmTIMER Ans+W→W End W/5

T05LIST (creating list test)

Code: Select all: 0→W For(A,1,5 DelVar L₁ Asm(prgmTIMER 999→dim(L₁ Asm(prgmTIMER Ans+W→W End W/5

T06LIST (sorting list of only 0s)

Code: Select all: 0→W For(A,1,5 DelVar L₁ 100→dim(L₁ Asm(prgmTIMER SortA(L₁ Asm(prgmTIMER Ans+W→W End W/5

T07LIST (sorting list of only 7s)

Code: Select all: 0→W For(A,1,5 DelVar L₁ 100→dim(L₁ Fill(7,L₁ Asm(prgmTIMER SortA(L₁ Asm(prgmTIMER Ans+W→W End W/5

RAYTRSPR ( this is a 3D modeling test using raycasting)

(I didn't make this program, this was made by TheScienceElf, you can view his video here.)

Code: Select all: Asm(prgmTIMER ClrDraw:1→G {12,24,23,22,21,20}→L₁ For(Y,0,162,2G) (81-Y)/164→B For(X,0,262,2G) (X-131)/164→A A²+B²+1→E:2B-12→F 34.75→H:F²-4EH→D 1/B→T AT→U:T→V remainder(abs(int(U)+int(V)),2)→C 12→L:12→M 12-(T>0)(C+1)→C If D≥0:Then (F-√(D))/(2E)→T AT→I:BT-1→J:6-T→K J/1.5→M If M>0:Then int(10M)→M L₁(1+int(M/2))→L L₁(1+int(M/2+.5))→M Else:12→M End {I,J,K}/1.5→L₃ {A,B,1}→L₂ 2sum(L₃L₂)→S SL₃-L₂→L₄ L₄(1)→P:L₄(2)→Q:L₄(3)→R (J+2)/Q→T If T>0:Then PT+I→U:RT+6-K→V 11-remainder(abs(int(U)+int(V)),2)→C Else:12→C:End Else:If T>0:Then 1→E:4→F U²+V²-12V+37.75→H F²-4EH→D 12(D≥0)+C(D<0)→L L→M End:End Pxl-On(Y,X,C) Pxl-On(Y+1,X,L) Pxl-On(Y,X+1,M) Pxl-On(Y+1,X+1,C) End:End Asm(prgmTIMER Ans

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!
