Texas Instruments TI-84 Evo vs Casio fx-9750GIII Graphing Calculator

Buy the TI-84 Evo if you want a color screen, a rechargeable battery and the calculator most US math teachers and standardized-test guides assume you have. Buy the Casio fx-9750GIII if you want a cheaper-feeling, lighter tool with MicroPython programming and long AAA battery life. The TI has the sturdier ecosystem and higher owner ratings; the Casio has more RAM and a programming language students actually use.

  • Choose the TI-84 Evo if you are taking the SAT, ACT or AP exams and want the model your teacher and test-prep books are written around.
  • Choose the Casio fx-9750GIII if you want MicroPython, a monochrome screen that sips battery, and a slide case that protects the keys.

What reviewers say

Texas Instruments TI-84 Evo

  • 4.5 / 541 ratings

Owners rate it well overall, with 4.5 out of 5 from 41 ratings. They like the color screen, the rechargeable battery and the familiar TI-84 layout. The main complaints are the small RAM and flash memory and the missing charging cable.

What people mention
  • Color screenPraisedOwners say the color display makes several graphed functions easier to tell apart.
  • BatteryPraisedThe included rechargeable battery is liked because it avoids buying AAAs.
  • KeypadPraisedUsers find the TI-84 layout and menus familiar and quick to learn.
  • MemoryCriticisedReviewers say 21KB of RAM and 3.5MB of flash fill up quickly with large programs and apps.

Casio fx-9750GIII Graphing Calculator

  • 4.2 / 540 ratings

Owners rate it well as a capable, affordable graphing calculator that handles coursework and exams. Reviewers like the Python support and the clear menu system, while some find the monochrome screen and key feel dated next to color models.

What people mention
  • DisplayMixedOwners say the monochrome screen is clear for graphs but lacks the color and sharpness of rival models.
  • PythonPraisedReviewers like having MicroPython on a calculator at this level for learning to code.
  • BatteryMixedUsers note it runs on four AAA batteries rather than a rechargeable pack, so they keep spares on hand.
  • Exam usePraised

Questions and answers

Which is better for the SAT and ACT?
Both are permitted on the SAT, ACT and AP exams. The TI-84 Evo is the safer pick because most US test-prep material and classroom instruction assume TI keystrokes. The Casio works fine if you already know its menu system.
Which has the better screen?
The TI-84 Evo. Its color screen shows up to 15 graph colors, so overlapping functions and inequalities are easy to tell apart. The Casio is monochrome and shows 21x8 characters.
Which lasts longer on a charge?
The Casio. Four AAA batteries run a monochrome screen for a long time, and you can carry spares. The TI uses an included rechargeable pack that you top up over USB.
Is the Casio worth stepping up to over the TI?
Only if you want MicroPython or more RAM. The Casio has 62KB RAM against the TI's 21KB and adds Python programming. The TI wins on screen, graphing color and classroom familiarity.
Which is better for programming?
The Casio. It runs MicroPython, a real language students can carry to a computer. The TI-84 Evo is limited to TI-BASIC, which is simpler but slower and less transferable.
Which is better for statistics and matrices?
The TI-84 Evo. It stores up to 10 matrices of 20x20 and lists of 999 elements. The Casio caps matrices at 6x6, which is tight for larger linear algebra work.
