Not as fast as your PC, though. Just think how much it has to do to make the graphics for a modern game look good.

Actually, I always wonder how it's possible that they work so slowly; sometimes, especially at work, I have to wait *minutes* before trying to open a folder or a program, waiting for it *to do its things*. But what on the hell do they have to do? Why we can't have any control on this?

How many calculations does it have to do.

My reply in this other thread[/url=]

Quote
The average desktop PC can perform about 100 million instructions per second. That may sound impressive but the IBM BlueGene/L can perform 360 trillion operations per second. That is officially the world's fastest computer. I think it would be pretty obvious which of those would be classed as a mainframe.

Incidentally, there is a computer, the RIKEN MDGrape-3, that is almost 3 times as fast as the BlueGene/L at 1 quadrillion operations per second. However, that computer cannot run the officical software that is used to rate speed so that is why the BlueGene/L is officially the fastest (I wonder who wrote that test software - IBM. maybe?)

But neither of those can match the human brain. That has been estimated to perform 10 quadrillion instructions per second.

They don't have to do a great deal of work to do by computer standards, I suspect they use logarithm's as if I ask mine to give me the cube root of -1 it go's 'bleep bleep' not possible whereas good software like Matmathica has no problem

My calculator still works if I do cube root of -1. Your's must be broken.

I have tried this on many calculators and many software calculators but very few give the correct answer.

Calculators only give you one value for roots! That's a serious problem if you are a School pupil and believe everything a calculator tells you. Mathematica gives you a proper answer to questions like that.

No it wasn't. That was an oblique reference to real & imaginary numbers. Very relevant to what had been posted previously about square roots.
