[itocp] Benchmark for i7 2600 @ stock vs i7 875K @ 3.4GHz - Page 8

post #71 of 72
I believe we will see some Ivy Bridge CPUs on LGA 1155.

Even if LGA 1155 never sees more than a 4 core CPU, they will remain top performers for a long time.

I actually am not sure if it can get that low. At some point, you actually cannot make a transistor any smaller since the atoms of the silicon and metal gate become the limiting factor. For example, if you always have to build something in a 5 to 1 ratio, you can never go any lower than 1 atom and 5 atoms. This would limit the total size to the size of those 6 atoms.

A quick google brings up the size of the silicon atom as about (if it was a square) .271nm. I don't know the 3 dimension size of the transistor, but if it takes any decent amount of atoms, the limit will probably be something like 6nm.

Then they need to figure out how to make a transistor out of something much smaller.

EDIT: Wow I guess my 6nm guess was pretty good. While I writing this, someone else posted the name number. Either we both made it up and got lucky or we both remember it.
