==Mainboard chipsets==
{{split|List of SiS chipsets|date=December 2020}}
One of the most famous chipsets produced by SiS was the late 486-age chipset 496/497 which supported [[Peripheral Component Interconnect|PCI]] bus among older [[Industry Standard Architecture|ISA]]- and [[VESA Local Bus|VLB]]-buses. Mainboards using this chipset and equipped with CPUs such as the [[Intel 80486DX4]], [[AMD 5x86]] or [[Cyrix Cx5x86]] processors had performance and compatibility comparable with early Intel [[Intel P5|Pentium]] systems in addition to a lower price.
[[File:ROCKY-518HV - SiS5598-2376.jpg|thumb|SiS 5598]]
After this late success, SiS continued positioning itself as a budget chipset producer. The company emphasized high integration to minimize the cost to implement their solutions. As such, SiS one-chip mainboard chipsets that included integrated video, such as the [[Socket 7]]-based SiS 5596, SiS 5598, and SiS 530 along with the [[Slot 1]]-based SiS 620. These were some of the first PC chipsets with such high integration. They allowed entire system solutions to be built with just a mainboard, system RAM, and a CPU.

The '''SiS 530''' (Sindbad) with SiS 5595 southbridge supported [[Socket 7]], [[SDRAM]] 1.5&nbsp;GB max., a bus frequency from 66&nbsp;MHz to 124&nbsp;MHz, and can have from 2 to 8 [[mebibyte|MiB]] shared memory for an integrated [[Accelerated Graphics Port|AGP]] SiS 6306 2D/3D graphics controller. Includes integrated [[AT Attachment|UDMA66]] IDE controller. mainboards using the SiS 530 were positioned as cheap office platforms and paired often with low-cost chips from [[Intel Corporation|Intel]] competitors, such as the [[AMD K6]] series or [[Cyrix 6x86]]. The graphics controller had [[Direct3D]] 6.0 and [[OpenGL]] support, although it was a very low-performance product for 3D acceleration.<ref>Masrani, P.

SiS and [[Acer Laboratories Incorporated|ALi]] were the only two companies initially awarded licenses to produce third party chipsets for the [[Pentium 4]]. SiS developed the 648 chipset with this license (SiS 648 B Stepping supports Intel Hyper-Threading CPU on some motherboards like MSI 648 Max).<ref>Lal Shimpi, Anand.
