We've gotten our hands on some leaked documents detailing a few new additions to Gigabyte's X79, more specifically the documents are pointing to the fact that Gigabyte has moved to new digital PWM controllers. At the same time, Gigabyte has posted the first official pictures of its X79 motherboards on its Facebook page, which gives us some further details as to what to expect from its upcoming X79 boards.

Let's start with the new digital PWM controllers. What we're looking at is one controller, or "digital engine" as Gigabyte seems to want to call it, for the CPU and two for the memory, i.e. one for each pair or quad of DIMM's depending on the motherboard layout. The controllers are made by International Rectifier, which recently acquired CHiL which is a well-known brand of a wide range of power related ICs. Because of the split memory banks, adding a separate power regulation circuitry to each side of the motherboard allows for an overall simpler board design in terms of power delivery. All of Gigabyte's X79 boards are also compatible with both the Intel VR12 and VR12.5 specs which suggest that we might be seeing support for Ivy Bridge-E on the X79 platform.

As for the motherboards themselves, well, we've already seen several previews of them, least not the G1 Assassin 2 which you can now ogle in its full glory below. It's pretty clear that Gigabyte designed this board with four additional SATA ports in mind, but thanks to Intel, there's now a blank space on the board where the ports should've been. There's really very little else to add about this board that we haven't already covered.

Moving on, we have the GA-X79-UD7 which sports the X58-OC colours and a small Gigabyte OC logo. Although the board carries a lot of pedigree from the X58-OC board, we're not looking at a feature stripped board this time around; instead this is a fully loaded model. Not too much appears to have changed since IDF, although once again, there are four missing SATA ports. The chokes appear to have changed as well from some rather industrial looking grey ones to some shiny black ones, but this also means that the total count has gone down from 22 to 18, suggesting fewer power phases. That said, we doubt it'll make much difference to anyone except potentially the most extreme overclockers.

Next up we have the GA-X79-UD5, the only board in Gigabyte's X79 range to feature eight DIMMs. Again only minor changes, such as the missing SATA ports, but otherwise nothing significant that we can notice. Once again, we think this will be the most popular X79 model from Gigabyte.

Finally we have the GA-X79-UD3 and as with the other three boards, we see the same blank space where the additional Intel SATA ports should've been. It'll be interesting to see if Intel decides to do a new revision of the X79 chipset in the future that adds these missing ports or not. This board was not posted on Gigabyte's Facebook page and as such we sadly only have a smaller picture from Gigabyte's unofficial/official blog.

Update: We've added a couple of better shots of the X79-UD3 which got posted separately on Gigabyte's Facebook page.
