Intel ...easily. Use any hardware comparison charts. Intel has been spanking AMD since the inception of the Core 2 Duo architecture.
Price difference for your selected CPU's:
AMD - $184
Intel - $269
I personally suggest the Intel Q6600 for $189. Still beats the AMD CPU, costs about the same and can be overclocked on the stock CPU fan really well.
