Overclocking
When we first took a look at the 0.15-micron R300 core, we were able to overclock
it from its stock 325MHz core clock to close to 400MHz in a lot of cases. With
the R350, although we're still dealing with the same 0.15-micron process, it
is over 6 months more mature and thus we can expect even higher clock speeds.
We were quite pleased to be able to overclock the Radeon 9800 Pro from its
stock 380/340MHz clocks to 420MHz core and 380MHz memory, without any visual
artifacts (at 430MHz core we started to develop artifacts, the same applies
to higher memory clocks as well). Note that this is an increase of 10% to the
core and 11% to the memory clocks of the Radeon 9800 Pro, not too shabby at
all considering we're still dealing with a 0.15-micron core without any excessive
cooling.

The overclock yielded a 10 - 12% increase in performance with 4X AA and Performance
