Systems' setup and notes

Here's a quick rundown of the test system should you wish to compare benchmark results with your own.
  • Intel Pentium 4 3.2GHz 800FSB HT CPU (ES)
  • AMD Barton XP3200+ S462 CPU (2200MHz / 200FSB)
  • VIA PT800 reference board. 68F44T6 BIOS
  • DFI LANParty 875PRo Canterwood
  • EPoX 4PDA2+ i865PE Springdale (05/08/03 BIOS)
  • EPoX 8RDA3+ nForce2 Ultra 400

Other components

  • ATi Radeon 9800 Pro (380/340)
  • 2 x 256MB Corsair XMS3500C2, run at 2-6-2-2 @ DDR-400 for all motherboards
  • Liteon 16x DVD
  • Samcheer 420w PSU
  • Samsung 181T TFT monitor
  • Akasa Silver Mountain cooler
  • Intel reference cooler

Software

  • Windows XP Professional Build 2600.xpclient.010817-1148
  • DirectX9
  • Hyperion 4.48 VIA service pack
  • NVIDIA nForce 2.03 drivers
  • Intel 5.00.1012 chipset drivers
  • ATI CATALYST 3.2 drivers and control panel (6307s)
  • Pifast v41 to 10m places
  • Lame v3.92 MP3 encoding with Razor-Lame 1.15 front-end using U2's Pop album
  • SiSoft SANDRA 2003 (MAX3 release)
  • Hexus SETI benchmark
  • 3DMark 2001SE
  • UT2003 Demo (Build 2206)
  • Comanche 4 benchmark
  • Serious Sam 2 Demo
  • Quake 3 v1.30 HQ

VIA recommended using a single 512MB DIMM for testing. It's in-house testing highlighted the fact that the reference board may not be fully stable with 2 DIMMS at DDR400 speeds. However, testing showed that our sample was perfectly stable with 2 x 256MB Corsair XMS3500 sticks at DDR400 speeds with 2-6-2-2 timings. We must note that the Corsair DIMMs were single-sided in nature and not what VIA ideally recommends for pure performance. We'll be looking at the effects of different memory sizes and types when we conduct a multi-board PT800 roundup in the near future; stay tuned. We experienced no untoward performance issues when running at stock speeds. 15 complete runs of 3DMark 2001SE v330 indicated that basic stability wasn't a problem.

Another aspect to note before we benchmark is that the EPoX Springdale board features a new BIOS with a far more aggressive memory implementation, giving Canterwood-beating performance. For the record, we'll state the running speeds of each board.

3222.6MHz - EPoX 4PDA2+ i865PE

3216.6MHz - VIA PT800 reference board

3207.5MHz - DFI LANParty 875Pro Canterwood

2205.3MHZ - EPoX 8RDA3+ nForce2 Ultra 400 (AMD)

So it's a refined single-channel chipset against two dual-channel Intel heavyweights and the cream of the crop as far as AMD is concerned, all battling it out at 200FSB.
