Newer calculators have a RAM chip that has only 48 kB. The chip has 128 kB, but Texas Instruments has not made an OS that uses all of it.

Like the TI-83 Plus Silver Edition, it features a 15 MHz Zilog Z80 processor and 24 kB of user-available RAM. The TI-84 Plus Silver Edition was released in 2004 as an upgrade to the TI-83 Plus.

The USB port on the TI-84 Plus series is USB On-The-Go compliant, similar to the next generation TI-Nspire calculator, which supports connecting to USB based data collection devices and probes, and supports device to device transfers over USB rather than over the serial link port. A USB port and built-in clock functionality were also added. The archive ( ROM) is about 3 times as large, and the CPU is about 2.5 times as fast (over the TI-83 and TI-83 Plus). The key-by-key correspondence is relatively the same, but the TI-84 features improved hardware. The TI-84 Plus is an enhanced version of the TI-83 Plus. There is no original TI-84, only the TI-84 Plus, the TI-84 Plus Silver Edition models, and the TI-84 Plus CE. The TI-84 Plus is a graphing calculator made by Texas Instruments which was released in early 2004.
