Spending time the San Francisco bay area usually results in some interesting finds. The first one I can talk about? An upcoming launch of refreshed Z68 motherboards from ASUS that include support for PCI Express 3.0 technology coming next year.
At first glance the board doesn't appear to be anything really different - it looks much like the Z68 boards currently on the market and the P67 boards before that. The heatsink and blue/black color scheme and the Deluxe moniker has been in use by ASUS since the initial Sandy Bridge processor releases. There are still 4 DIMM slots, 8 SATA ports, USB 3.0, Bluetooth, dual Gigabit Ethernet and more sitting right there, easy for us to see.
But unlike previous boards from ASUS, this one is the first we have seen to offer and validate support for the upcoming PCI Express 3.0 standard rated at 32GB/s rather than 16GB/s. ASUS is actually the last to market with the so-called "PCIe 3.0 ready boards" as we have seen boards from MSI, Gigabyte, ASRock and others on PC Perspective previously. In fact, we just published a review of the MSI Z68A-GD80 (G3) board yesterday that offers the same feature.
Still, ASUS isn't one to sit by and let the competition pass so they built their own Z68 board that is now 100% ready for PCIe 3.0 devices and the pending Ivy Bridge processor from Intel. The board will support full speed PCIe 3.0 speeds in both single GPU and SLI/CrossFire configurations. In fact, ASUS says that both the BIOS and PCIe switches are ready, out of the box, with this new P8Z68 Deluxe GEN3 model, something that some other vendors' boards may not actually be. That would mean the necessity to have a Sandy Bridge processor on-hand to flash the BIOS before an Ivy Bridge CPU would POST. Just something to keep in mind.
ASUS is hesitant to call the PCIe 3.0 support anything but future-proofing for consumers worried about the next-generation of graphics solutions from NVIDIA and AMD, though I would point out to our readers that any cards that come out in 2012 that do run PCIe 3.0 will still work just fine on PCIe 2.0 boards.
That being said, an ASUS rep did mention in passing that they MIGHT have found another benefit to PCIe 3.0 on current systems and graphics cards: a reduction in microstuttering in PC gaming. Now, I have yet to see this benefit in person and my initial thought was that this was simply a placebo effect, but I am eager to try it out when I get this board at the labs.
