Benchmarking
Setup
All
test were doing using Nvidia's Detonator v. 21.85.
The benchmarks were run on WinXP and overclocking
of the cards were done using the coolbits registry
hack. All other grahic settings were left to default.
The
system that tests were run on feature a AMD Duron
700 clocked at 6.5x146 ( 950 Mhz ) sitting on an IWill
KK266 motherboard. With 1 256MB PC133 and 1 128MB
PC133 ram, running on conservative memory settings.
When testing for overclocking, both cards were pushed
to the maximum until they either showed artifacts
( corrupted image quality ) or literally stopped working.
The system was reset and then the cards were tested
on both higher and lower settings till they
worked flawlessly. The cards overclocked a bit higher
than those settings used but for safety and stability
issues they were, "throttled down" a bit.
Quake
3 Benchmarks
We
start off by running Quake 3 at its "high quality"
setting with the resolution brought down to 640x480
from its default 800x600. Here both the Geforce2 Ti
and the Geforce2 MX400 aren't loaded enough to really
tax there fillrates ( and memory bandwidth ). Even
when overclocked, the MX and the Ti really gain no
tangible performance increases. At a resolution this
low, performance is limited by the platform ( CPU
+ Memory ) the game is running on.
Still at a color depth of 32bit, we begin to see how
the Geforce2 Ti begins to pull way from the MX400.
The Geforce Ti is a 50% faster at this resolution
when compared to the MX400. Even when overclocked
the Geforce Ti still has a 30% lead over the MX400,
which is already beginning to show its bandwidth limitations
at this resoluton.
Overclocking the MX400 increases its performance by
15% percent. Which closely matches its 16% increase
in memory bandwidth. ( default memory clock 184Mhz,
increased to 215Mhz ).
The
Geforce2 Ti however, is unaffected by overclocking.
Only showing that 6.4GB/s of bandwidth provided by
its 200Mhz DDR SDRAM ( 400Mhz effective ) is more
than enough to run this game at this resolution (
1024x769 ) and color depth ( 32bit ).
The Geforce2 Ti is 88% faster than the MX400 at this
resolution! And is 61% faster than the overclocked
MX400. We see that the MX400 begins to be hampered
by its limited bandwidth at resolutions above 1024x768
in quake 3.
Overclocking the MX400 at this resolution ( 1280x1024
) gives it approximately 17% more "power".
Which really helps! The Geforce2 Ti also gains a decent
10% from overclocking.
