Socket 7
licensed the VIA Apollo VP2/97 core logic architecture as its AMD 640 chipset.[Socket 8], [Slot 1] and [Socket 370]
- ProSavage PM133 - Graphics core from S3, derived from a combination of the 3D component of Savage4 and 2D from Savage 2000.
- PLE133 and PLE133T - Graphics core from Trident, derived from Blade3D.
- CLE266 - Graphics core from S3, derived from S3 Savage series under the brand name UniChrome.
- Asus advertised some boards as Apollo Pro 133Z. 133Z appears to be a late revision of or step up from 133A, but it is not listed on the VIA site.
Slot A and Socket A
- KT266 contains a hardware bug which causes system instability when using the AGP slot at the specified max capacity of 4×.
- ProSavage KM133, KM133A, KM266, KM400, KM400A - Similar to the above, but with integrated graphics. After KM133, DDR is supported. The KM133 uses an IGP consisting of the S3 Savage4 3D core and Savage 2000 2D functionality. KM266's ProSavage8 IGP is similar but has an additional 3D pipeline. The KM400 chipset and its "A" variant use the VIA UniChrome IGP. KM400A supports FSB 400 unlike the KT400A
- Later revisions of the KT333 are rebadged KT400 chips with AGP 8x disabled. On motherboards with this chipset AGP 2x cards which require 3.3V are not supported.
- KT133E appears on Gigabyte 7IXEH but is not listed on the VIA site. Based on the specifications of that motherboard, KT133E appears to be equivalent to KT133, supporting 133 MHz for memory but only 100 MHz for the CPU.
- Some revisions of KT333 support 166 MHz FSB.
Socket 423, 478 and LGA 775
- Being a reduced version of PM880, PM800 is not as closely related to PT800 as P4M890 to PT890. Because of its high cost, It is soon obsoleted in favor of P4M800 and then P4M800 Pro, both of which have a lower rated V-Link and feature no special memory technology such as FastStream64 or StepUp that is common in the other listed 8xx chipsets.
- VIA PT890, P4M890, PT900, P4M900 – VIA's PCIe-only chipsets. The P4M chipsets have onboard graphics VIA UniChrome Pro.

Athlon 64
- VIA K8 series – Athlon 64 chipsets. Established an early market lead, with richer features, and a full speed HyperTransport implementation
- VIA K8M890, K8T890, K8T900 – VIA's PCIe-only chipsets. The K8M chipsets have onboard graphics VIA UniChrome Pro.
- The Athlon 64 chipsets do not have memory controllers, because memory controller is integrated into the CPU. Supported memory types depend on the CPU and socket used.

- 8233: manual does not mention 3com 10/100 at all and there is not connector - I believe the citation above to be possibly made by someone who does not have 8233
