威盛的官網說8237支援1066GB/s

The unique VIA Modular Architecture Platform (V-MAP) ensures that the VIA VT8237 is pin-compatible with the previous generation of South Bridges, considerably reducing design times and thus speeding products to market. The VT8237 also features the new Ultra V-Link chipset interconnect bus that delivers high data throughput of up to 1066GB/s with low latency from the South Bridge to a wide array of VIA North Bridges, including the very latest platforms. The VIA Hyperion unified driver base is another major feature of V-MAP, that allows end users to benefit from seamless hardware and software compatibility and optimize system performance.
