when do you think a cpu will no longer be able to increase speed

super_xero · 10-21-2005, 11:39 AM

hey i was wondering since cpu are getting faster faster wouldnt there be a time where you couldnt go faster it wouldnt be possible ect games will become as relestic as they can be cpu could become eventually extreamly fast u click on something it come up you rip a movie it does it in one sec you rip music again one sec when do you think this will happen

If we look at the past, we've always thouht that "this is very fast", but then new ones come out and make that one look obsolete. Now in terms of video encoding or w/e, if we put something like a Pentium 6 6.4Ghz with 6MB cache, sure it will encode it extremely fast, but as newer cpu's come out, so do more demanding app's and games. In the near future, we will have Blu-Ray and HD-DVD's, anc they will take a much longer time to encode (and probably more cpu intensive then now).

But i do think that we cant just keep going up and up in clock speed, so i bet that they will move more towards building 2-core, 4-core, and 6-core! cpu's. Thats my opinion.

Yep, I would agree with geoff5093!

I wonder if the technology Sony used for the Cell processor will be available for PCs in the future or a CPU similar to it. It looks like a really nice peice of hardware and it is extremely small.
I think that CPUs will be able to increase in speed for a long time but not in the same way. We will eventually reach the limits of what a peice of silicon will do and we will ahve to find a new material to make it out of that will withstand more heat and provide a better base for CPUs. Think about it, CPUs have always been made out of silicon, we will eventually have to "evolve" CPUs to a new and better material.

We have already reached the max speed a CPU can browse through your computer, you can't get any faster than instantly after you click, the window comes up. The only heavy tests for CPUs will be when encoding and video games. But even now video games are starting to be less and less CPU intensive and more and more GPU intensive.

I dont remember the specifics of what im about to say but I had a class in college in which the professor was mentioning something about like a .01 micron barrier or something like that. Basically, if i remember correctly, it was something to do with not being able to squeeze light or something past that barrier, thus, limiting the amount of transistors.

yeah, but who says we need to use, it harldy the smallest thing in the universe.

First lets make a distinction between speed and performance. Which has been covered many time before

As for physical size limits, they only exist in current materials used. There are methods of transporting data at infinate speed with zero mass (think lepton spin). Make cpus in using that technology if you must

speed of light will eventurally become a limiting factor for the internal design of chips (unless Einstein wrong

)

There is a size barrier for transistors but I don't think it has to do with light. As you probably know a transitor needs 3 peices (PNP, NPN) so in theory the smallest it could be is 3 atoms. A further limitation is how many you need to create the basic gates used. Sooner or later you will hit a size limitation (assuming transistors remain the basis of ICs).

we all ready know that light is not the fastest thing, gravity (and there theorised gravitons) for example is infinate times faster than light,

true,

but who says you have to stop at an atom. Since we are donning our hypothetical hats, you could use any subatomic particle.

how so?

speed of light:299 792 458 m / s
gravity: 3.8 meters/ sec squared approx.

unless your are talking about something differnt fill me in
