Although we did show you a fair few pictures of MCP7A derived, or Geforce 9300 and 9400 motherboards during Computex, what should be the final clock speeds for the IGP on these chipsets have turned up over at HKEPC alongside with some additional details of the chipsets.

The two models are codenamed MCP7A-S (the Geforce 9300) and MCP7A-U (Geforce 9400) and the standard features are quite similar between the two. Both support 1,333MHz bus speed, dual-channel DDR2-800 or DDR3-1,333 memory, we're not sure if we'll see combo boards based on either chipsets, or if it's even possible, one x16 PCIe slot, up to four x1 PCIe slots/devices and up to six PCI slots.

There's also support for up to six SATA ports with RAID 0,1, 0+1 and 5, Gigabit Ethernet and up to 12 USB 2.0 ports. Display connectivity comes via either D-sub, DVI, HDMI or DisplayPort, in other words, just about every standard interface is supported.

So what about those clock speeds? Well, the Geforce 9300 will have its GPU clocked at 450MHz with the shaders at 1.2GHz, while the Geforce 9400 will be clocked at 580MHz with the shaders at 1.5GHz. We'd presume the difference between the two is purely a speed binning and that the Geforce 9400 will feature a bigger cooler, or it might even need active cooling, but time will tell if this is the case.

Both chipsets does of course support Hybrid SLI, PureVideo HD and Cuda. I looks like Nvidia will finally have a competitive Intel chipset, although the question is if it's not too little too late, although we'd expect both to beat Intel's G45 chipset in 3D benchmarks.
