To test the Tyan KT400 in its 3D
gaming performance, we used the latest versions of Comanche
and Quake 3 Arena. Quake 3 may be a little outdated,
but still gives a good idea of memory bandwidth performance
in a system. All tests were run at default and
3 and Comanche 4
OpenGL and Direct 3D
Here we can see
how important memory bandwidth is. The nForce2 boards
have managed to pull ahead by about 15% once again.
The KT400 simply cannot keep up with the dualDDR performance
of the nForce2 chipset. The frame rates we are seeing
from the KT400, however, are still very respectable and
would offer a very satisfactory gaming experience.
Comanche 4 is
not as dependent on memory bandwidth like Quake 3, and is
more dependent on CPU cycles. We can see this by the
fact that the nForce2 boards did not keep the same lead in
this benchmark, as we saw in previous tests. Here the
nForce2 boards only managed a 9% performance gain.
Obviously the increased memory bandwidth explains the
advantage, but in this benchmark, does not provide as much
as an upper hand. The KT400 chipset's performance is
still admirable and more than sufficient for today's
