P67X UD3R B3 Gigabyte quietly launches the P67X series of motherboards

Although Gigabyte showed off one of its P67X motherboards at CeBIT in the beginning of March, that board has as yet to turn up, but the company has quietly added a couple of other boards from its P67X series to its website. The two models are the P67X-UD3 and P76X-UD3R, both of course using the B3 stepping chipset.

Although Gigabyte showed off one of its P67X motherboards at CeBIT in the beginning of March, that board has as yet to turn up, but the company has quietly added a couple of other boards from its P67X series to its website. The two models are the P67X-UD3 and P76X-UD3R, both of course using the B3 stepping chipset.

So what makes these boards different from the P67A series? Well, from what we can tell there are some small but important changes as well as one rather odd one. Comparing the P67X-UD3 to the P67A-UD3 the most visual change is a much larger heatsink on the chipset and also a relocation of the chipset position on the motherboard away from the PCI Express x16 slots. This has also lead to the SATA ports being moved to the front of the PCB and they're now angled at 90 degrees.

In addition to those changes, Gigabyte has also added a Marvell 88SE9172 SATA 6Gbps RAID controller which we're not familiar with and that doesn't appear on Marvell's website. On top of that we gave a pair of Etron EJ168 USB 3.0 host controllers which means you get two rear ports as well as two front ports via an internal USB 3.0 header. Finally a VIA FireWire controller has been added, a feature missing on the P67A-UD3

The PWM heatsink appears to have shrunk a little bit though and gone is the blue streak of colour found on the P67A-UD3. Finally the colour of most of the rear ports has changed from black to red for some reason and we can't really figure out why. Still, it might make them easier to see under a dark desk, but it's the only thing we can think of that would make any sense.

As for the P67X-UD3R we're looking at Gigabyte's new black PCB and all of the changes done to the P67X-UD3 are carried over here too. In fact, the only difference we can see between the two boards is a different PWM design for the P67X-UD3R going up from six to 10 phases and it's apparently using Driver MOSFETs, something the P67-UD3 appears to be lacking. Again we're missing the blue colour highlights on the heatsinks of the P67A-UD3R and it also appears like Gigabyte went with a pair of smaller PWM heatsinks on the P67X-UD3R.

We can't really see anyone not picking a P67X over a P67A board; unless the P67X are a lot more expensive, but we have a feeling it won't be the case despite the extra features. What we don't understand is why Gigabyte is offering two very similar SKUs that will compete directly with each other. We're still waiting for the P67X-UD4 which showed up at CeBIT, but we're sure it'll arrive soon enough and it might even get accompanied by more X series boards from Gigabyte.
