Intel's 32nm is as good as AMD's 40nm

The following table from http://techreport.com/articles.x/21099 tells an interesting story:

Code name	Key products	Cores	Threads	Last-level cache size	Process node (Nanometers)	Estimated transistors (Millions)	Die area (mm²)
Penryn	Core 2 Duo	2	2	6 MB	45	410	107
Bloomfield	Core i7	4	8	8 MB	45	731	263

Llano	A4	2	2	1MB x 2	32	758	-

Intel's quad core SB i7 CPU is built on a 32nm process with 995 million transistors on 216 mm^2 die area, or 4.6 million/mm^2. In comparison, AMD's Llano APU has 1450 million transistors on 228 mm^2 die, or 6.36 million/mm^2.

In other words, AMD's 32nm is 38% denser than Intel's.
