HP-Prime performance test - color graphic programs
Several websites have begun comparing the TI-Nspire CX, Casio Classpad II fx-400CP and HP-Prime performances by using the softwares now available online.It is a mistake because beyond the performance of the host computer, those software are often not emulators but simulators. They're running a system which has been rebuilt for the computer.
The calculation performances are often in direct link with the processor speed, and therefore we can expect the HP-Prime calculating faster than all its competitors.
Where we sometimes do have some surprises, is with programs dealing with lots of outputs/displays, mostly games. In fact, there is no dedicated graphic processor on our calculators. Thus output instructions "plunders" processor time, which consequently has less time to process calculations of the program itself. The more pixels and colors the screen can display, the more calculations required are required and it is a problem particularly for the TI-84 Plus C Silver Edition.
Therefore lets's check this evening if the HP-Prime's processor has the same problem. We will use our HP-Prime DVT prototype, and the new color tunnel game made by DJ_O for the HP-Prime software:

Now lets get a look of the game directly on the calculator itself:

It rocks... it's so fast that it becomes unplayable! {:thumbsup:}
On the HP-Prime we don't have access to assembly programs, and we wouldn't dare imagining what it would have done... The power of assembly is usually used by other calculator models for games. It seems it might be possible on the HP-Prime to develop huge games without a single line of assembly! You might even need to slow down your games with some loops! :P
But of course, the speed is not the only advantage of the assembly language, it also allows you to perform many usually achievable things... ;)
