The
Switch
To
try and rationalise these results it seemed like a
good idea to run the tests on a KT333 motherboard,
in this case the Albatron KX400 Pro. This will serve
to force both the Ti4200 and the Ti4680 to operate
on AGP4x which should in theory result in similar
scores. To demonstrate the effect of Fast Writes on
performance each test will aslo be run with them enabled.

From
these results a few things become evident. The first
is that both cards perform better on the KT333 chipset
than they do on the KT400 when running at identical
settings. Next, the performance of both cards is significantly
closer on the KT333 than it is on the KT400, in fact
for the first time during testing the Ti4680 took
a miniscule lead when running with an AGP aperture
of 256MB, not enough to fall outside the margins for
error but a win's a win and the Ti4680 is due one
so let's let it have its moment of glory shall we.
Finally, we can conclude the Fast Writes is a real
performance killer. On both motherboards enabling
Fast Writes caused a worrying drop in performance.
If you're running with Fast Writes enabled I suggest
you at least do a little benchmarking to see what
effect it's having on your overall performance.
Just
to rule out the incredibly slim possibility that the
whole fast writes deal is a perculiarity of 3DMark
here's UT2003 run in the same way.
