The TI-84 Plus is a descendent of the TI-83 Plus and the TI-83 Plus Silver Edition; it was released in 2004. Like the TI-83 Plus Silver Edition, it has a 15Mhz processor. It has more Flash memory (480KB) than the TI-83 Plus, though less than either the TI-83 Plus Silver Edition or the TI-84 Plus Silver Edition. It has 24KB of RAM, like all calculators since the TI-83. The biggest differences obvious to casual users are the USB-on-the-Go port at the top of the calculator and the curvier, redesigned case.
