Lego Mindstorms EV3....how fast is it?

Hello fellow mindstorm-ians, :lol:

As many of you know, the new EV3 comes with an ARM9 300Mhz processor, comparing to the NXT, which has an ARM7 48Mhz processor...
Now, the question is...
How much faster is it? Let's say we have a physics engine for the NXT, and with 10 objects on screen, it runs at around 8 frames per second. With the new EV3 processor, how many frames do you think it will get?
Also, are the math calculations on the EV3 any faster(any guesses on how much?)?

Well, that's all folks,

I don't have details specs and numbers, so this is only an informed guess.
I'd presume that the ARM9 in the EV3 comes with the hardware FPU/Vector unit which is standard for the ARMv5TE architecture (not all ARM9s are based on ARM5TE). The hardware FPU would probably be the biggest contributor to any performance gains in the EV3. Given that physics simulations are mostly floating point, I think you won't be disappointed :0)

Of course, this also presumes that whatever code that is written will take advantage of the FPU.

O_o
According to Wikipedia, the Nintendo DSi uses a 133 Mhz ARM9 processor....and the EV3's processor is clocked at 300 Mhz...
Does that mean the EV3 is faster than the DSi? :o

We can only hope! :mrgreen:

Take that, Nintendo!! In Your Face!! :P

speed is not only an issue of the processor clock but mostly of the code and the operating system.
with genuine ARM code and pointers the NXT already might probably be 100x faster than currently with the Lego firmware or other bytecode interpreters instead Iguess (of course depending on the source code).

2-3x as fast as before you probably won't even realize during runtime.
