How fast is the HP Prime?

The only way to truly understand the cost of emulation in the 50g is to fab a 75 MHz Saturn processor and run them side by side. Otherwise, you're comparing a 400 MHz ARM device running native code against who knows what. Did you not expect it would be faster even against a 75 MHz device running native code?

Did I miss something here?

You are missing that jebem is testing how the device is "presented" to the user, not how it can be 'hacked' to run faster.

In the other hand, I think integration is the poorest thing implemented on the 50g, I always had troubles with EXP(X... integrations. It seems that the method used by casio and TI implements some pre-catched results (because I often noticed that the results were a bit approximated in the other devices, I am not sure if this is the case exposed in the video). In my opinion, an implementation of an algorithm like Riemann sum in the devices would represent a more truly comparison, but we will see that soon in the next video with n-queens.
