I really googled this for a while. I couldn't find it out.<br>
I think its okay to ask this here.<br><br>
>Why does it make sense to make CPUs smaller and smaller.<<br>
Seems like the big problem with building these things is that they get to warm.<br>
So why would CPUs not just be as big as a motherboard?

smaller nanometer technology, needs less space<br>
production is more efficient

Use less power, less heat, more transitors in the same space, more efficient, the list goes on.

the nm measurement is the gates and whatnot...<br><br>
That just means that you can use less power to send the signal through. And, since the process if smaller you can' fit everything closer together....so it's slightly faster (not noticeable)...and also you can fit more on a single wafer at the manufacturing plant.

and the smaller they get the less heat there starting to produce, cheaper to make (because there using less material), better overclockers... I don't really see why not.. Why go bigger when you could go smaller? do you really want to revert to room sized computers?

For some reason I hear that a smaller nm usually runs cooler, such is seen with the xbox360 they know they have a cooling problem so starting sometime next year the cpus will be a smaller nm (I belive 65..68..or so)

VERY off-topic. Why do you have Dolph in your avatar? It's a Danish "comedian" and a blue hippo <img alt="" class="inlineimg" src="/images/smilies/tongue.gif" style="border:0px solid;" title="Stick Out Tongue">

Smaller architecture means you can fit more on a single chip. For example, Intel's upcoming 45nm chips will have 6MB L2 Cache instead of the 4mb we see on 65nm Conroes today <img alt="" class="inlineimg" src="/images/smilies/wink.gif" style="border:0px solid;" title="Wink">

I have Dolph because I think he's funny. Avartars are for fun after all.<br>
I hoped some day somebody would notice him and ask.

lol that's not why.<br><br>
To put an extra 2mb they actually have to add to the chip

That's correct^^<br>
You can get more chips per wafer with a smaller architecture which means more money!!<br>
it's increases the Internal Rate of Return, to a greater value allowing their MARR (minimum acceptable rate of return) to increase without ppl throwing a conipschit.<br>
Anyways that's beside the point.<br>
Point is it means <b>more money and higher quality at lower power consumption.</b><br>
Cheers!

Actually sideburns he's right with a smaller process you can squeeze more L2 on the chip... For example lookit the northwoods and prescotts; sure the northwoods ran cooler, but that was because the prescotts crammed on twice the cache, but with only ~30% more space to work with.

That doesn't mean they're not adding to the chip though like he said... cuz they are.
