5 Texas Instrument Graphing Calculator – A Comparative Review

Antonio Evans February 11, 2019

5 Texas Instrument Graphing CalculatorParents often ask: “How do I help my child improve in math and science?”

Traditionally, the parents send their children to tutors to aid the learning process. Even after intense sessions, the child still may not comprehend that tough concept.

But, there is another way to help the child. You (the parents) had this tool at your finger-tip but never realized it.

A great tool to help your child better understand math and science is a graphing calculator. You say “Wait, I buy my child a calculator. In fact, I do this every year.”

But, do you also provide training on how to use it? Texas Instrument has a full line-up of graphing calculators and is willing to show you how to get the most out of them.

The calculator, if used properly, can help your child grasp difficult mathematical formulas and theories. This guide will explore five graphing calculators from Texas Instruments.

Then, it will compare these tools against each other and provide you with information on which tool best fits your child’s needs.

Product Comparison

This comparison will examine these five (5) graphing calculators from Texas Instrument (TI): TI-83 Plus, TI-84 Plus, TI-84 Plus CE, TI-89 Titanium and TI-Nspire CX CAS.

5 Top STEM Graphing CalculatorsThe criteria used in this examination are memory available for use by product operator, design, functionality, pre-installed applications and if device can be used on standardized test.

At the end of each criterion, I will select a winner. This evaluation is based purely on what each device has to offer. When selecting a calculator for yourself or your child, you must consider where you and they are at in the learning process.

Design

TI-83 Plus versus TI-84 Plus

Physically, the TI-83 Plus and the TI-84 Plus are similar. In fact, the only difference is that the TI-84 has a mini-USB port while the TI-83 does not. Both calculators use the same type of central processing unit (CPU) (Zilog Z80), and the displays are the same (96 x 64 pixels).

TI-83 Plus versus TI-84 PlusThe processor on the TI-84 has a faster clock (operates at 15 MHz instead of 6 MHz (TI-83 Plus)), therefore it should process requests a little faster. The devices also are powered by four (4) AAA batteries. Both calculators have an I/O port but the TI-84 Plus also includes a mini-USB port.

TI-83 Plus versus TI-84 Plus CE

The TI-84 Plus CE has slimmer body than the TI-83 Plus. The TI-84 uses a rechargeable battery (designed to last around two weeks on single charge) instead of AAA batteries. Its CPU is three times faster than the TI-83 Plus CPU.

TI-83 Plus versus TI-84 Plus CEThe color display on this TI-84 is much bigger (320 x 240 pixels). This feature allows the user to see a graphing request in better detail. The TI-84 Plus CE only has a mini-USB port (in contrast, the TI-83 only has an I/O port).

TI-83 Plus versus TI-89 Titanium

The TI-89 is major upgrade over the TI-83 Plus. Its CPU processes much more data at a faster speed. The display (160 x 100 pixels) is bigger and allows the user to see the plots much better. Both calculators need four (4) AAA batteries for power.

TI-83 Plus versus TI-89 TitaniumThe TI-89 has two to access it: (1) I/O port and (2) mini-USB port.

TI-83 Plus versus TI-Nspire CX CAS

The TI-Nspire CX CAS is the luxury item in the Texas Instrument graphing calculator line-up. It has a high-powered CPU for crunching the most complex task. Its display (320 x 240 pixels) gives the user the visual quality of 1st generation smartphones.

TI-83 Plus versus TI-Nspire CX CASThe calculator is powered by a rechargeable Lithium-ion battery that should last two weeks on a single charge. The TI-Nspire CX CAS only has a mini-USB port that allows the user to interface with a computer.

TI-84 Plus versus TI-84 Plus CE

The TI-84 Plus CE uses a rechargeable battery (designed to last around two weeks on single charge) instead of AAA batteries (as used by the TI-84 Plus). Its CPU is three times faster, thus a quicker processing time.

The color display on this TI-84 Plus CE is much bigger (320 x 240 pixels). The TI-84 Plus CE only has a mini-USB port (in contrast, the TI-84 Plus also has an I/O port).

TI-84 Plus versus TI-84 Plus CEOddly, the TI-84 Plus (released in 2004) is not the predecessor of the TI-84 Plus CE (2015). The non-color version of the TI-Nspire holds that distinction.

TI-84 Plus versus TI-89 Titanium

The TI-89 is major upgrade over the TI-84 Plus. Its CPU processes much more data at a faster speed. The display (160 x 100 pixels) is bigger and allows the user to see the plots much better.

Both calculators need four (4) AAA batteries for power, and both devices can be accessed via an I/O port and a mini-USB port.

TI-84 Plus versus TI-Nspire CX CAS

The TI-Nspire CX CAS has the same advantages over the TI-84 Plus as it had over the TI-83 Plus. Its CPU is much faster and processes data quicker.

TI-84 Plus versus TI-Nspire CX CASThe Nspire’s display is also superior to that of the TI-84 Plus. The TI-Nsprie only has one access port on it (a mini-USB port). Both devices use the TI.

TI-84 Plus CE versus TI-89 Titanium

The TI-89 Titanium has a faster CPU and provides more access to it (I/O and mini-USB ports) than the TI-84 Plus CE. This allows the user to process mathematical problems efficiently.

TI-84 Plus CE versus TI-89 TitaniumThe TI-89 screen (160 x 100 pixels) is smaller and black/white.

TI-84 Plus CE versus TI-Nspire CX CAS

The TI-Nspire has the same advantages over the TI-84 Plus CE as those versus the TI-84 Plus. The Nspire brings the user’s experience into the 21st Century.

TI-84 Plus CE versus TI-Nspire CX CASTI-89 Titanium versus TI-Nspire CX CAS

The TI-Nspire CX CAS supercharges the TI-89 Titanium and brings the user into the age of the smartphone. It reduces the user learning time of how to implement the device effectively.

Conclusion: The TI-Nspire CX CAS is the clear cut winner for this criteria. The calculator gives the user the feel of a 1st generation smartphone.

TI-89 Titanium versus TI-Nspire CX CASSince most students are familiar with how a smartphone and computer work, they reduce the learning curve of deploying this device.

The Computer Algebra System (CAS) is the reason the ACT will not allow the TI-89 Titanium and TI-Nsprire CX CAS into their testing facility.

The Right TI Calculator for the ExamQuestions and Answers

Can the operating systems on the evaluated calculators be updated?

Answer: Not all of the evaluated calculators can be updated. The TI-83 Plus’s operating system cannot be updated. You can update the other four devices by downloading the necessary software from the TI website via computer and transferring the software to the calculator.

Explain why the TI-Nspire CX CAS is not allowed for the ACT

Answer: The TI-Nspire and the TI-89 are not allowed on the ACT because they have a computer algebraic system. Texas Instruments makes a TI-Nspire without the CAS functionality that is allowed on the test.

Summary

Before selecting a TI graphing calculator, you need to determine which math and/or science courses you plan to take.

For middle school through most of high school applications, the TI-84 Plus family (includes the TI-83 Plus, the TI-84 Plus and the TI-84 Plus CE) should provide everything you need.

For college, you should go with either the TI-89 Titanium or the TI-Nspire CX CAS.
