My HP 10bII+ is much faster than HP 12c!

Yeah, that is pretty much normal. There are only 2 or 3 calculations that can possibly show the "running" message if I remember correctly due to the speed. (inverse T, cflow, interest calc - if memory serves right)


As others have pointed out, provided you can live with the non-RPN, the non-programability, and the "not quite as good hardware" - it actually is a more capable unit. The 12cp will be much slower then either a new 12c or the 10bII+ (which both use a modern, ARM processor while the 12cp uses a very slow, older design). When comparing the original 12C compared with the newer 12cp, you'd generally see anywhere from a 4x-8x speed increase over the original 12C. The newer 12C is about 120x-140x the speed of the original. The 10bII+ will be in the same speed range.

There are some exams that only allow either the 12C/12CP from the HP side of things (CFA/CFP???). So that might be important to check for you depending on future plans.

There is a rather authoritative 10bII+ review found in a newsletter here if you are interested. http://h20331.www2.hp.com/hpsub/download...011_v2.pdf

Quote:I believe it also uses higher precision math (Tim?) internally, plus provides extended math functions not available on the 12C/12CP.

Yes, the 12/15 digit napier library is in use on the 10bII+.
