TI-73 and TI-84 are perhaps among the most wallet-friendly, yet reliable graphing calculators currently present in the market. A decent graphing calculator is completely vital if you are studying more advanced math subjects like Algebra, Statistics, and Physical Science. Well, even though it is said that these two models are among the most wallet-friendly products, you can get TI-73 under a hundred bucks, while TI-84 is priced higher. Which one should you choose? Take a look : TI-73 Vs TI-83.

TI 73 Vs 84

TI-73 Pros
TI-73 is, of course, cheaper than TI-84. The several dozens gap can be very significant if you are running on a tight budget. Somewhat interestingly, TI-73 also has a bigger available RAM than TI-84. TI-73 has 32 KB of RAM with 25 KB accessible to the user. On the other hand, TI-84 has 48 KB of RAM with 24 KB accessible for the user. The bigger accessible RAM allows longer inputs to be taken.

TI-84 Pros
First, TI-84 is faster than TI-73 because its processor has a higher clock speed (15 MHz vs. 6 MHz). Calculating complex and super long equations is more time-efficient with TI-84. The total RAM in TI-84 is also larger, making it smoother and more reliable for running various programs. Second, the total storage in TI-84 is also larger (1 MB of Flash ROM vs. 512 KB of Flash ROM). Thus, you can save more programs in TI-84. You also need to know that TI-84 already comes with 12 built-in programs for your convenience. Third, though the functionalities are identical between these two models, TI-84 can handle much bigger things. For example, while TI-73 can only graph four functions simultaneously, TI-84 can graph up to ten graphs at the same time. TI-73 only has thirteen zooming options, but TI-84 has fourteen zooming options.
