Soyo's SY-7VMA - PM133 Socket 370 Motherboard
The i815 should be nervous...

Our test system specs should be noted for a proper backdrop on which you can compare performance numbers.

Pentium III  933MHz.,  Soyo SY-7VMA Motherboard, 128MB of PC133 True CAS2 SDRAM from Mushkin, IBM 30Gig 7200 RPM ATA100 Hard Drives, nVidia GeForce 2 GTS  64MB  AGP Graphics Card , Plextor UltraPlex 40X CDROM, WinME, DirectX 8, nVidia Detonator 3 Drivers version 6.31, VIA 4-in-1 4.25a

Benchmarks With The 7VMA
The PM133 with a Dash of BX Lovin'...

The first benchmark out of the gate is SiSoft's Sandra.  Sandra is a synthetic benchmark that allows us to test specific sub-systems.  We've had a Soyo SY-6BA+100 here in the labs for a while and decided to see how it stacks up against the SY-7VMA.  The SY-6BA+100 is based on the Intel 440BX chipset and incorporates a HighPoint UDMA/100 hard drive controller.

As you can see, performance is on par with the BX chipset in every test.  Even though it does a great job and performs very well at a 133MHz. FSB, the BX was never meant to run that high.  The BX board's AGP and PCI buses are heavily overclocked at this FSB which can cause instability when certain cards are installed in a system.  For stability's sake, the PM133 is a much better choice when using a CPU with a 133MHz. FSB.

Also notice the aggressive timings with both boards.  At what should be a default speed of 933MHz., the SY-7VMA is reporting a speed of 945MHz.  Even the SY-6BA+100 reports a speed 5MHz. higher than it should.

We also ran a couple of Sandra's tests while our CPU was overclocked.  Let's see what kind of effect an 11MHz. jump in FSB speed has on the tests...

CPU @ 1008MHz.                                  MEM @ 1008MHz.
             

The memory performance was excellent at 144MHz.  The Pentium 4 using MUCH more expensive PC800 RDRAM destroys all of the competition, but the SY-7VMA ranks right up there with the rest of the competition.
