GIGABYTE X470 Aorus Gaming 7 WIFI Motherboard Review (Page 4)

X470 Aorus Gaming 7 WIFI Circuit Analysis Continued


GIGABYTE made sure to use Realtek's ALC1220-VB chip, which seems to have better microphone input SNR compared to the normal ALC1220. They then used Nichicon electrolytic capacitors and WIMA film capacitors to improve audio quality. We also find a nice ESS SABRE ESS9018Q2C DAC with quite nice ratings, and on the back of the motherboard we find a Texas Instruments L49720 operational amplifier, but for some reason, it's not mentioned in the marketing.


We find the old faithful Intel i211AT Gbit NIC on the motherboard. One thing GIGABYTE also really didn't market to the extreme is that they are using Intel's brand new 1.733Gb/s Wireless-AC controller that supports current bands but also the new 160MHz band that delivers the Gbit WIFI speeds. The Wireless AC 9260NGW was used as a standalone WIFI controller.


An ASMedia ASM1143 USB 3.1 controller we only find on AMD boards for the most part (it probably takes in two PCI-E 2.0 ports) is located on the motherboard along with a Texas Instruments HD3220 type-C switch chip. USB 3.0 DAC-UP 2 is possible because of a Richtek RT8288A chip.


There are eight fan headers on the motherboard and two external temperature input headers as well as multiple other temperature sensors built into the motherboard, and two embedded controllers are used. One is visible; it's the IT8792E, the other is hidden under the bottommost x16 slot that operates at x4 speeds. The ITE IT8295FN provides the digital RGB LED capability on the motherboard.


The main SuperIO is the IT8686E, and it handles system management and some fan control. An ICS 9FGL1214AKLF is the clock generator we find on the motherboard. The motherboard also offers two 128Mbit (16MB) BIOS ROMs.


We find multiple ASMedia ASM1480 PCI-E quick switches that move around PCI-E bandwidth. We see the Texas Instruments L49720 operational amplifier on the back of the PCB that helps out the audio section.
