unknown Chinese motherboard manufacturer that goes under the name of Topstar has sampled a board to Chinese language website Yesky.com.
This isn't a final revision, but it features the upcoming MCP73S if the specs are anything to go by, as the board is lacking HDMI.
The MCP73 for Intel or the GeForce 7050 and the GeForce 7025 should be available some time in September if everything goes according to plan, that's less than two months away.
The board itself doesn't look that remarkable, although it has one interesting feature, a Post 80 debug LED just above the D-sub connector on the rear I/O, something we've not seen on a mATX board before.
The MCP73 is a single chipset solution, so the south bridge is built into the same package as the north bridge. It's worth noting that all three models of the MCP73 will only support single channel memory, so don't expect the performance to be spectacular.
There will be three different version in the end, with the top of the range MCP73PV, which will be known as the GeForce 7050 being the only one supporting DDR2 800 memory along with HDMI. All three models should have the GPU clocked at 333MHz.
