Expreview published some information about the upcoming NVIDIA MCP7A-U chipset.
But instead of canceling, 730i will keep exist and have new chipset, the MCP7A-S. In other words, MCP7A-S will have two names, one is GeForce 9xxx (still can not conform its name) and the other is 730i. The GeForce 9xxx is a uATX form factor mobo, with less PCI, PCIe and other expansion slots. 730i is a ATX mobo and has more expansion slots.
MCP7A-U is the top class chipset in the MCP7A family. Though it could be named as GeForce 9XXX, it will be come the first mainstream uATX mobo with DDR3-1333 support. Sources inform us the MCP7A-U will be the “fastest mGPU”, but who knows.
Motherboards with this chipset are expected in July.
