Both calculators allows you to view 3D graphs, as well as perform 2D/3D plotting. Both calculators are equipped with the Computer Algebra System (CAS), which allows you to perform calculus and arithmetic functions easily by offering multi-faceted symbolic and numeric solving (there are also built-in applications specifically for tougher equations). Both calculators have a PC connectivity kit included, as well as a USB cable. The HP 50g is a step up from the lower cost 48gII, in that it has a 2MB ROM memory (the 48gII has no ROM memory), 512KB RAM memory (the 48gII's RAM is only 128KB), 75MHz ARM9 processor (the 48gII's ARM9 is only 48MHz), 9 line display (the 48gII's is only 7 lines), and SD card slot. The HP 50g comes with a one year warranty.
