32nm is better than 22nm?

post #1 of 7
Thread Starter 
I was just wondering how small and cool was intel's 22 nanometres. So I read the fact sheet about it. Then I compared it to 32 nanometres' fact sheet and found out the difference.

A 22nm transistor can switch on and off well over 100 billion times in one second.

Does that mean that 22nm transistors are inferior to the 32nm transistors? Does that mean 22nm processors will clock poorly than 32nm ones?

Define "inferior".

They might have lower switching rates but are smaller and use less power.

There's many more factors to consider, Power consumption being one of them. New architecture = more performance and 9/10 a better overclocker.

If this wasn't the case then intel's architecture would be going up in size rather than smaller

By inferior I mean weaker. smile.gif
So isn't transistor switching rates linked to entire processor's clock speed?

The clock speed is determined by an oscillating crystal, in this case it's a silicon crystal.

Weaker is not a concise definition of inferior in terms of transistors. There are dozens of multi-dimensional characteristics of transistors. Switching rate is just one.


The theortical limit of a processor clock rate has the transistor switching rate as a variable. However, there are many many many things that come before this being the limitation (i.e. skew, electromigration, synchronization)

Yes, but bear in mind 22nm is a 3d structure vs the standard planar structure of a 32nm. The number quoted is usually the so called "ft", the speed at which a transistor hits unity gain (did intel measure it identically in both cases?). It can be used as a rough indicator of a processes potential. However In cmos, the gain has to be higher than 1, so what really matters is the gain vs frequency. The gain is one of the reasons why the processors aren't faster. 300 billion times a second would imply 150GHz speeds, however we barely hit 5GHz reliably at 32nm, therefore there are other things limiting the speed to 5GHz which may be overcome by the move to 22nm. Of course 22nm (because of the change from planar to 3d) might not be refined enough to give a raw performance increase, however the limiting factor for Intel is often power and because of the smaller size (switching power depends heavily on capacitance) the power usage for the same cpu will be much lower in 22nm enabling more cores or higher clocks or both.
