In the low power netbook and small notebook processor areas, the Intel’s Atom N550 and the AMD’s C-60 are are very close in performance.
While AMD’s C-60 is clocked lower at 1.0 GHz, it supports turbo boost, which more than makes up for its slower clock speed. The N550 is clocked at 1.50 GHz. Both processors are dual core.

Some more details of Atom N550
The Atom N550 significantly improves upon the N450 and N455 by integrating two cores in the processor ( The N450 and N455 have only 1 cores). The Cache also gets doubled to 1 MB. The Atom N550 should enhance the utility of the net books by providing a little more processing power juice.
Some more details of AMD C-60
The C-60′s main improvement over the C-50 is the introduction of the Turbo Boost feature. As you can see in the bench marks it improves the performance of the AMD C-50 processor significantly without increasing the TDP rating.
In the next post we will compare the benchmark results of these two processors.
