System Performance

One of the key questions is how the increased memory bandwidth translates into system performance. Of course, this depends on the application but, in general, the applications that show most benefit are gaming applications like Quake3 Arena and Expendable to name only 2 examples. There is no real point of showing CPU benchmarks, neither is there a point in showing any high resolution gaming benches that merely reflect the limitations of the graphics adapter. The same goes for I/O limited benchmarks like ContentCreation Winstone that only shows how fast your HDD is, so I'll keep it short and sweet.

Quake3 Arena

Quake3 Arena average frame rates at the Fastest, Fast, Normal and High Quality settings. On average, the KT266A chipset achieves in a 10-11% higher system performance over the KT266.

Expendable

Expendable Timedemo shows the same results as Quake3 Arena with an 11% higher system performance. for comparison, the SIS chipset (ECS K7S5A) is shown.

Ulead MediaStudio Pro

Aside from gaming applications, content creation programs such as Ulead MediaStudio Pro 6.0 are the prime candidates for performance increase with higher memory bandwidth

Ulead MediStudio Pro runtime in seconds for creating an MPG file (40 MB) from a 50 MB AVI file. The KT266A chipset takes a clear lead over both the SIS735 and the KT266 chipset
