Overclockers New Zealand has posted a review on the VIA P4XB-S DDR Motherboard

The P4 1600 system just couldn't keep up with AMD XP1600 system in every benchmark except Quake 3 Arena. Please take note that the motherboard is made by VIA, the chipset maker itself. There is a high possibility that this motherboard hasn't been optimized for maximum performance. We have Abit KR7 in our AMD system and this motherboard is known as a tweaker's board and Abit's motherboards are particular strong in memory performances. However, this still can not fully justify the poor benchmark scores from P4 compared to an AMD XP1600 system. The performance gaps are farther than I expected as an overclocked P4 to 1840 Mhz is still behind an XP1600 at default speed
