Gigabyte had several motherboards on display at CES including an AMD AM4 motherboard with an unreleased AMD 400-series Promontory chipset! The stealthily displayed AORUS branded motherboard was spotted by Steven Burke over at Gamer’s Nexus who then jumped at the opportunity and started taking it apart! The AORUS X470 Gaming 7 WiFi appears to check all the boxes for a high-end gaming focused motherboard and should allow enthusiasts eyeing a Ryzen or Zen+ (Ryzen 2000 series) processor to push it as far as possible.
We went hands-on with the AORUS X470 Gaming 7 WiFi
The X470-based motherboard features a six layer PCB and improved CPU power delivery in the form of a 10+2 power phase (doubled 5-phase for CPU plus 2 phases for memory) with VRMs that are cooled by a hefty copper heat-pipe and aluminum fin stack. Gamer’s Nexus reports that Gigabyte is using hardware from International Rectifier in the form of IR 3599 drivers, IR 3553 MOSFETs, and a IR 35201 PWM controller. For those interested in how motherboard VRMs and power phases works, Buildzoid has several great introductory videos on Youtube that are worth watching.
Other overclocking friendly features include an external clock generator, diagnostic LED readout, power and clear CMOS buttons on the rear IO panel, dual BIOSes, and various hybrid fan headers for air and water cooling. Gigabyte reportedly rates the motherboard at 4,000+ MHz memory overclocking which is good news for Ryzen and Ryzen 2 users since memory speeds have a big impact on performance.
The AORUS X470 Gaming 7 WiFi feeds the AM4 socket with both an 8-pin and 4-pin ATX power connectors. To the right of the processor socket sits four DDR4 DIMM slots and the accent LED along the right edge. Expansion is handled by three PCI-E x16 slots (two are wired to the CPU for graphics), two PCI-E x1 slots, and two M.2 slots that sit under black head spreaders. There are six SATA ports in the right corner. While the heatsink is covering the audio chipset, whichever solution they are using (likely Realtek as it does not appear this is a Killer-equipped board) has high end WIMA and Nichicon caps and also supports USB DAC-UP technology.
Rear I/O includes two antenna connectors for the built in Wi-Fi chipset, power and clear CMOS buttons, four USB 3.0 ports plus two more USB 3.0 ports that support USB DAC-UP, two USB 3.1 ports (one Type-C and one Type-A), a RJ45 connector (likely Gigabit Ethernet), and six audio outputs (one S/PDIF and five 3.5mm analog outputs).
It is interesting to finally see a 400-series motherboard and for Gigabyte to give AMD its Gaming 7 treatment. Also comforting is that while the new 400-series boards will offer slight connectivity benefits, users that bought into Summit Ridge and X370/B350/A320 boards aren’t missing out on too much and may actually get multiple CPUs out of one motherboard for a change. The 400-series chipsets allegedly enable a bit more bandwidth for devices hanging off of the chipset thanks to the upgrade from PCI-E 2.0 (5GT/s) to PCI-E 3.0. With this upgrade, a M.2 drive connected through the chipset would be able to hit its full speeds. While the chipset’s eight PCI-E 3.0 lanes could in theory support two nearly full speed M.2 NVMe drives, the PCI-E 3.0 x4 link between the chipset and processor would ultimately bottleneck things. At least a single drive can hit its full speeds though and bring Ryzen systems up to three total PCI-E M.2 drives running at full speed.
Oh, and did I mention there is RGB? Yep, Gigabyte has hooked the X470 Gaming 7 WIFI up with RGB LEDs around the PCI-E x16 slots, DIMM slots, over the chipset, and under the accent overlay in the top right corner. All things considered, the RGB is pretty tame in this model, which isn’t a bad thing in my opinion.
What are your thoughts on Gigabyte’s upcoming motherboard and on the 400-series motherboards in general? Are you ready for Pinnacle Ridge?
