SIS735 Chipset
The SIS735 is the first DDR-compatible Athlon chipset from Silicon Integrated Systems. As with the previously reviewed SIS730 chipset, the 735 is a single-chip solution aimed at lowering manufacturing costs as compared to standard two-chip solutions, such as VIA's KT266. The integrated design also offers another significant advantage, as both the northbridge and southbridge controllers can utilize a high-speed, low-latency interconnect bus since both are housed within the same die. The internal multi-threaded bus operates at full chipset speed, thus the I/O transfer rate can reach nearly 1.2 GB per second. This is an impressive rating, as even VIA's latest V-Link bus can only offer a peak 266 MB per second interconnect rate. The SIS735 also offers simultaneous concurrent transactions, while V-Link operates in a singular access manner. The performance advantage is tremendous, as the SIS735 drives the entire PCI bus to its maximum operational limits.
