How fast is the HP Prime?

I didn't bother looking at the video but from your description this is not an apples-and-apples comparison. There is nothing to conclude from it except relative device speeds, all things being unequal.

The 50g is Saturn emulated on 75 MHz ARM. 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?
