As we noted
earlier, we had the SY-6VBA-133 fired up in no time so we proceeded
to crank up the benchamarks!

again, the SY-6VBA-133 handled an overclock of our P3-533B to a top
end of 620MHz. (155X4). This was the top end bus speed for the
board. If we had a few more notches higher with the FSB, something
tells me we could have done even more. The system was totally stable
throughout. Just for good measure and reality sake, we did our tests
at 533MHz.(133MHz. x 4) and 600MHz. (150MHz. X 4). Your processor
may get different results but the SY-6VBA-133 is a good base to
SY-6VBA-133 - 600MHz.

comparison, we threw in a Sandra benchmark of the latest
Soyo BX board
with the exact same set up. As you can see, the VIA chipset lags
slightly in overall compute performance (MIPS). The FPU numbers are
very close. Regardless, this type of difference in either spec is
probably imperceptible to a user in "real world"
Here are the
default speed Sandra numbers at 133MHz. FSB.
Sandra 99 - Soyo SY-6VBA-133 - 533MHz.
We set up the Soyo
again for comparison. Again, as far as the CPU numbers go, things
are pretty much neck and neck. Where the VIA Apollo PRO133 chipset
lags a little, is disk performance. We think this may be due to the
fact that the VIA EIDE Bus Master Drivers are still a little young.
Perhaps the gap will close a little as time moves on and VIA
releases new revisions.
OK then, we know what you folks are thinking. That was good coverage
on the CPU and Disk Performance side of things but what about AGP
4X?! Recently we learned from one of our astute readers that the VIA
Apollo PRO133 chipset does not in fact support AGP4X. Only the
Apollo Pro133A rev. of the chipset supports this. It looks as if the
SY-6VBA-133 that we tested was designed with the first rev of the
chip not the "A" rev.
As a result, the board we tested supposedly is not capable of AGP4X.
We'll confirm this with Soyo and post another update.
There IS a
setting in the BIOS that says "2X AGP Enable". You can
enable or disable it. However, the manual doesn't tell you anything
about this BIOS option. We asked Soyo for a response to our question
on this as well. We hope to hear back from them shortly. We will
also post an update on this as soon as we get further information.
Our assumption is that this switch enables AGP 2X or disables it
down to 1X mode. What we have for you now is a Quake3 Arena Demo
benchmark with the "2X AGP" settings disabled and enabled.
results are for one resolution, 1024X768 at 32bit color and
textures. We also set the texture size bar to the default high
quality setting and then to the max setting. We used Quake3 version
1.08 for our tests.
to check our system specs
just to refresh yourself on the other components
ourselves if Soyo tells us that the 2X AGP setting is something
different. :-) However, as you can see, the 2X AGP setting does seem
to give a slight boost in performance. That boost is lessened at the
higher resolution texture setting. What can we conclude with respect
to AGP 4X in this case? As we noted before, unfortunately not much.
We'll just have to wait and see if the VIA PRO133A gives a
"real-world" boost with its AGP4X.
is indicative of standard Soyo product. It is a quality piece of
workmanship with excellent stability and a good well rounded set of
features. The VIA chipset it is based on is a competitive system
solution that does have room for improvement with its maturity.
Additionally, the "SDRAM Plus or Minus PCI Clock" setting
in the BIOS should give added flexibility for those looking to run
133MHz. FSB CPUs with PC100 memory. Thus, consumers will not be
forced to shell out the extra money on new PC133 memory if they are
looking to save a few dollars. We would have liked more detailed
documentation with this board. However, all told, this is solid new
technology from Soyo which should serve you well for aggressive
overclocking and the like. For many folks, the AGP and Memory bus
manipulation features of this board may be the only way to achieve
certain higher end fringes of overclocking.
