What are the key differentiating factors of 32 nm technology against 45 nm architecture. Apart from the fact the dielectric oxide thickness been reduced to 0.9 nm and gate length minimized to 30nm, which results in highest current drive, optimized power leakage by 5times and better performance/power?

its smaller... pretty key factor.

Its smaller is the major factor. Because it is smaller you have less resistance, heat and the yield (number of processing cores) is higher for us. So production costs drop and amount of processors produced is increase all the while increasing the performance of the processors manufactured.

you can also get more per interation of the production process, i.e. per wafer, and therefore the ability to create more product per wafer.

often the benefits of a dyeshrink are mixed. when amd did it to there athlons they actually lost performance by about 2% per standard clock. but it did mean that the smaller cpu's could give better overclocks often as much as 15 percent as opposed to the original chips 5 percent.
with todays cpus there is a mixed bag of results. intel are likely to get a good 20-40% improvement from there dyeshink on the sandy parts because they will also introduce 3d transistors with lower resistance HI- K materials. amd on the other hand will again loose a few percent because of the bigger overall design which means the HI-K materials have to be slightly thicker meaning more resistance and more heat. end result is a 5-10% increase in overall performance.

so as the cpus get smaller the performance gap is increasing between the 2 manufacturers.

This sounds like a homewrok question.....

I really need to understand what is the performance aftermath on a reduced, here on a 32nm silicon die?
