What's the difference between the AMD 780 and 790 chipsets?

[SunnyD]

I remember seeing a comparison of the 790 chipset a month or so back, but I can't find it anymore. Does anyone have a link to a comparison between the 780 and 790 chipsets from AMD and what the main differences are?

obvious difference is that 780G/780V have IGP & 790X & 790FX don't.

Is the unobvious things I'm looking for... so far (unless simply undocumented in the 780G):

Auto Xpress* The technology for qualified performance boosts that automatically activates with AMD/ATI components to deliver better CPU, GPU, and system performance

* Boosts graphics bandwidth when using AMD processors with HT1
* Reads special Enthusiast DIMM settings for higher memory performance
* Enhanced DDR2 tuning to deliver better system performance. Maximizes performance from new AMD Phenom CPUs

Kindof like NVIDIA's PEG-Link it looks like.

GPU-Plex Technology Scalable twin-engine technology, all on a single chip, enables flexible configurations for multiple graphics cards on a single x16 link.

Not sure what that means...

Quad PCIE Blocks* Native PCI-E cores on one chip means fast GPU to GPU communications by eliminating the latency and possible bandwidth issues of multiple PCIE chip designs. Double pumped with Xpress Route for fast Core to Core transfers.

More PCIe lanes?

So is the 780G and the 790 essentially the same chipset with the exception of the GPU or a different beast all together... hmm.
