SiS6326 Performance

The SiS6326 reference card I tested came with 8MB of Siemens -10ns 100MHz SDRAM onboard and had a small heatsink covering the graphics controller itself.  The card passed muster on each of the five super7 mainboards (Iwill xa100 Plus, FIC VA-503+, EFA Viking 3, SOYO SY-5EMA+, AOpen AX59Pro) that I ran it on, showing virtually no incompatibilities whatsoever.  For the 3D Winbench 99  and 3DMark 99 Pro tests shown below the test system was as follows:

Mainboard Iwill XA100 Plus
L2 Cache 512K
Processor(s) AMD K6-2 350MHz
Cyrix MII 333
Intel P233MMX
Memory 64MB PC100 (Generic)
Hard  Drive Western Digital AC 36400 UDMA
Operating System Windows 98

You'll notice that the test were run at a screen resolution of 640x480 and a color depth of 16bpp.  Scores reflect an average of three runs of the benchmark for each processor.

Futuremark's 3DMark™ 99 Pro is a good measure of 3D performance.  Over and above the 3DMarks scores, the fill rate and texture rendering speeds are very telling as to the cards 3D performance.

Although the SiS6326 has an integrated triangle setup engine, it is still somewhat CPU reliant for optimal performance as the scores above detail. 

You may be wondering why, with all of the new high performance graphics controllers currently available, we decided to review the SiS6326 graphics chip. 

approved.gif (5878 bytes) To put it simply, the chip has found its way into thousands of sub-$1000 home PCs.  With names like Matsonic, PC Chips, Eurone, Amptron and even Diamond Multimedia incorporating the chip into controller cards and mainboards, we thought it a wise idea to test its performance and compatibility.  The SiS6326, while not a monster gamers chip is nonetheless a stable workhorse in the super7 arena providing excellent 2D and video performance, and at an unbelieveably low price.  Current market reports show cards based on the chip available from $28.00 and up.
