For comparison’s sake, on Intel’s 45 nm process, a single Atom
core with L2 cache is 14.1 mm squared. AMD is using TSMC’s 40 nm
process, which is a half node away from Atom’s process. There would
be roughly a 15% decrease in die size due to the shrink, so we would
still be talking around 12 mm squared for the Intel Atom on 40 nm. If
these performance figures are correct, then AMD has done an absolutely
amazing job with the Bobcat CPU in terms of processing density in a
low power configuration."
