Default new machine : CPU : 22 nm vs 32 nm

I've listed what's available at the local store,
which I trust to stock reliable items, tho' I wouldn't ask their advice.

All the AMD's are 32 nm , while the Intel recommended by one commenter
-- Core i5-3570 4-Core Socket LGA1155, 3.4 Ghz, 6MB L3 Cache, 22 nm --
is 22 nm : it costs CAD 230 & they have 3 in stock,
which suggests demand, but not the most popular ( 9 in stock).

Isn't 22 nm going to be faster than 32 nm ?

In the same price range, AMD offers Bulldozer X8 FX-8150 (125W)
8-Core Socket AM3+, 3.6 GHz, 8Mb Cache, 32 nm ( CAD 220 , 2 in stock).

How do you compare cores vs nm ?
How far is cache size important ( 6 vs 8 MB )?

When I built my current machine 2007, the CPU cost CAD 213 ,
so both look as if they're in the right ballpark.

who cares?

depends on the architecture.

In the absence of further explication, I'm likely to go with 22 nm .

These answers are not very helpful : does anyone have anything more so ?

It occurs to me that a larger cache goes with more cores,
so the last question is not so important.
