TI-84 Plus CE vs TI-83 Plus: Honest Comparison

Shopping for a school graphing calculator? This TI-84 vs TI-83 comparison settles the debate honestly: screen, battery, MathPrint entry, memory, and price, compared side by side — so you can pick the right model with confidence.

Quick answer: The TI-84 Plus CE wins for most students: color backlit screen, rechargeable battery, MathPrint textbook-style entry, and more memory — it costs more new. The TI-83 Plus is the older monochrome workhorse, cheaper used, and still does the same math. Both are allowed on the SAT, ACT, and AP exams. Buy the CE unless you already own an 83 Plus.

The short verdict

If you are buying today, get the TI-84 Plus CE. It is the current model, it is what your classmates and teacher most likely use (so keystrokes match), and its color screen plus MathPrint make everything easier to read. The TI-83 Plus only makes sense if you already own one or find one very cheap. In short, the TI-84 vs TI-83 debate has a clear winner for new buyers.

Head-to-head comparison

• Screen: TI-84 Plus CE — 320×240 color, backlit display. TI-83 Plus — 96×64 monochrome, no backlight. This is the single biggest day-to-day difference.
• Battery: TI-84 Plus CE — built-in rechargeable battery, charges over USB. TI-83 Plus — 4× AAA batteries you replace.
• Entry style: TI-84 Plus CE — MathPrint shows fractions and roots the way textbooks print them. TI-83 Plus — classic single-line entry.
• Memory: TI-84 Plus CE — 3 MB Flash ROM. TI-83 Plus — 512 KB Flash ROM. Both run the same core math.
• Speed: The CE’s newer processor evaluates graphs and programs noticeably faster.

What about the math — is one more powerful?

For school math, no. Both run the same operating-system family: graphing, STAT lists and regressions, MATRIX operations, DISTR distributions, and TI-BASIC programming all work on both. Neither has a CAS, which is exactly why both stay exam-legal. The TI-84 Plus series is a direct descendant of the TI-83 line — you can read its full history on Wikipedia.

Exam acceptance: SAT, ACT, and AP

Both calculators sit on the College Board’s approved list and are permitted on the SAT, ACT, AP Calculus, and AP Statistics exams. Bring whichever you practiced on; familiarity beats hardware on test day. (Note: an online calculator is not accepted in testing centers — only the physical device.)

Price and value

The TI-84 Plus CE costs noticeably more new — it is the current flagship. The TI-83 Plus is older, so new units are scarce, but used ones sell cheap.

• Buy the TI-84 Plus CE new if this is your main calculator for the next few years of school.
• Keep the TI-83 Plus if you already own one — it handles every class the CE does.
• Buy a used TI-83 Plus only as a budget backup, and test every key before paying.

TI-84 vs TI-83: which one should you buy?

Students starting fresh → TI-84 Plus CE. The color screen and MathPrint genuinely reduce mistakes, and every tutorial (including ours) matches its menus.

Already own a TI-83 Plus → keep it. Spend the money on practice, not plastic — the math is identical.

Teachers buying class sets → TI-84 Plus CE. Uniform hardware means one set of instructions works for everyone.

Frequently asked questions

Can the TI-83 Plus do everything the TI-84 Plus CE does?
Mathematically, essentially yes — same functions, same statistics, same programming. The TI-84 vs TI-83 difference comes down to hardware and convenience.

Is the TI-84 Plus CE allowed on the SAT?
Yes — like the TI-83 Plus, it is a non-CAS graphing calculator on the approved list. Bring the physical device; online emulators are practice-only.

Should I upgrade from a TI-83 Plus to a TI-84 Plus CE?
Only if the monochrome screen or AAA batteries genuinely bother you. For grades alone, the upgrade buys convenience, not capability.

Do both calculators run the same apps and programs?
Largely yes — TI-BASIC programs written for one usually run on the other. The CE simply has more Flash memory, so it holds more programs.
