[Softpedia] Nvidia's MCP77 Chipset: 15 USB ports and 22 PCI-Express Lanes

post #1 of 10
Thread Starter 
Nvidia has never excelled in elaborating on its chipset roadmap, and sometimes, it seems that the confusion is deliberately inflicted. Rumor has it that Nvidia's response to the AMD RS780M chipset, the MCP77 mobile chipset, will come factory-default with 22xPCIe lanes and 15xUSB ports. Top all of that, the chipset will arrive earlier than expected: in March.

The rumors that have emerged until now claimed that the MCP78
would only have 19 PCI Express lanes, of which only 18 would be available in SLI chipsets (because of the four links). Some other tech websites claimed that MCP79, also known as MCP7A (the Intel-ready chipset), would sport 20 PCI Express lanes. Both chipsets were reported to come with 12 USB ports only.

If the rumors prove to be true, it means that the MCP77M chipset will have two stock keeping units (SKU): the first one will provide support for 15 USB ports and 22 PCI-Express lanes, while the second will only support 10 USB ports and 20 PCI-Express lanes. The first SKU will come with support for Hybrid SLI and PureVideo HD, while the latter will not. In order to furthermore confuse the user, the last year reports claimed that MCP67 and MCP68 were in fact two names for a single chip with identical features.

Other websites point that Nvidia is cooking a MCP7C chipset for Intel platforms that is scheduled for release at some point in August. The alleged chipset is "known" to have a 64-bit memory bus, yet there is no further documentation regarding its specifications, and it might not even exist. And, if we are about to find out the mystery behind the MCP78/MCP77 chipsets in a short while, the MCP7C will stay in its lair for quite some time.

am i reading that right? 16 SLI pci-e ??? @_@ 16 x $200 (8800gt) = $3200 or.. 16 x 500 (8800gtx) = $8000... anyone wanna try and benchmark? hahahah

Nope I believe that you aren't reading that right. 22 PCIe lanes, remember that a normal PCIe slot for graphics cards are PCIe 16x, using 16 lanes. Then there's those smaller PCIe ones, 1x and 4x. So maybe 1 16x, 1 4x and 2 1x? Dunno.

And this is also a mobile chipset, so this isn't a desktop thing. And they haven't invented the type of SLI to work with 16 GPU's yet. Unfortunately SCA-SLI hasn't been released yet. (That's super-crazy-awesome SLI if you were wondering.)

Tell me how that even would be possible..unless you have a motherboard the size of a full tower case LOL

This has already been posted but...
1) why would any system need 15 USB ports?
2) Each PCIe lane creates heat even when not in use. Why so many lanes?
Once again...

lots of 1TB ext harddrives XD = small form mobo = small case = oOo haha

probably would rather about heat from cpu/nb/sb/gfx more than heat from pci-e
