AMD's Brisbane Core - the Transition to 65 nm And the cache latency
(Author: MS, January 5, 2007)

F.E.A.R.

F.E.A.R. is one of the most computationally intensive games out there. We were using the built-in benchmark running everything at medium quality with volumetric lights sturned On and set to medium as well at 640 x 480 pixels resolution.

Frames per second, higher is better!

There is a 2% delta between the 90 nm and the 65 nm parts with the older, 90 nm Windsor core being faster. Interestingly, the "underclocked" 4600* is faster than the 4800*, which reflects primarily the difference in the memory bandwidth between the two settings.

Frames per second, higher is better!

Again, we see the 4600+ Windsor CPU taking the lead over the 4600* (underclocked) followed by the 4800*. Memory bandwidth completely makes up for the 100 MHz deficiency of the underclocked Brisbane core.
