i just wanna know the difference between .13 and normal AMD CPUs... wats does .13 mean ?

.13 is a measurement of size. Right now its in units of microns. The smaller the size the more circuitry can fit into an area.

And the higher the speed can go with out cooking the chip.

And the lower the yield and higher the cost to manufacture. But thats not relevant to the end user.

.13 is the mesure of the die cut of the cpu witch is in fact 0.13 micron: 1000 time smaller than a millimeter. The smaller it is, the more circuits you can put in the same amout of space so it gives the ability to add more cache and new instructions. The yield is the % of CPU that can be selled off the waffer which is like a big circle with many core (chips) on it. So if you have a yield of 15%, you will have to make your chips expensive will if you have a yield of 90%, you can make them cheap.

Woot !! well put Pun.
plus smaller die requires lesser voltage & generates lesser heat, thus pertain to higher speed like Larac said......but you will still fry the damn chip, just a matter of time.

A picture of a silicon wafer on the 0.13 micron fabrication process (the GeForce FX wafer is shown).


Same wafer, just zoomed in.

Intel use bigger waffer size... I don't rember

Bigger waffer means you can use more of the edges as there will be a shallower curve. more chips, less wastage = lower price. or higher profit.

hahhaha... thx guys... many economics there...
so that means i should get a CPU that is .13 if im getting a new one right ?

btw.. which of the new thoroughbreds are best at overclocking... and what stepping ?

thanks

the best is 1800+ but some are still palomino (.18) and 2400+ . Check www.amdforums.com  for stepping help.
