1. Preface
For ordinary users, flagship motherboards are a bit overwhelming because they cannot use many interfaces and functions at all, and there are many design details that are redundant for them. They will basically not use them once during the entire life cycle.
Therefore, for ordinary users, mid-to-high-end entry-level motherboards may be the best choice. It has excellent performance in basic materials and expansion capabilities; it is also very careful in appearance and details, which is completely different from those mid- and low-end boards that are mainly suitable for use; it is also convenient enough in terms of functional performance. It is no exaggeration to say that it has about 80% of the flagship motherboard, but the price is indeed less than half of it.
In addition, the X670 series motherboard of AMD is still very powerful. Whether it is the X670 motherboard or the X670E motherboard, the functions are very powerful. It is equipped with two Nanqiao chips , which is a bit outrageous! Today I will talk about the X670 Elite AX motherboard of Gigabyte and see how the materials are designed for this board. GO ELITE, great enough!

▼There are still various dense components on the back of the motherboard.
▼ The memory slot part supports DDR5, so the contacts of the memory socket cannot be seen on the back of the motherboard.
▼The main PCIe slot supports PCIe4.0 maximum, so metal contacts can be seen on the back of the motherboard. There is also a physical partition design in the audio part in the lower right corner to ensure the signal-to-noise ratio of the audio.
▼AMD's 7000 series processor uses a brand new metal back panel, black, with a very complex design, with two fixing screws at the four corners.
4. Gigabyte X670 AORUS ELITE AX Xiaoyu Motherboard Disassemble
▼ The motherboard must be disassembled and see how the materials are used.
▼First remove the M2 metal heat sink at the bottom of the motherboard to expose the four M2 slots below. The uppermost M2 slot supports PCIe5.0, with a maximum support of 25110 specifications, and the remaining three support maximum support of 22110 solid state.
▼Only after removing all the metal covers on the motherboard, you can see the true face of the motherboard.
▼The metal heat dissipation parts are very large in size and have complex shapes. There are various heat dissipation fins on the surface, which can increase the contact area with the air and improve the heat dissipation efficiency. In addition, there is a heat-hospital heat pipe between the two heat sinks in the power supply part of the motherboard to improve the heat dissipation efficiency.
▼After removing the metal heat sink on the front of the motherboard, you can see the densely packed components on the front of the motherboard.
▼The power supply module of the motherboard looks very luxurious. There are 11 inductors on the left and 9 inductors on the upper side. The specifications are very powerful.
▼The input part of the CPU power supply module is a dual 8Pin auxiliary power supply, with voltage-regulating filtered inductors and capacitors on both sides.
▼Under the auxiliary power supply socket of dual 8Pin is the PWM main control chip of the power supply circuit, silk-printed XDPE192C3B. This is the latest PWM main control chip of in . There is no relevant information on the Internet. Mushroom speculates that it supports the maximum output of 12-phase dual-channel PWM control line number.
▼ DrMos silkscreen 21472 powered on the left is also DrMos produced by Infineon, with a maximum stable output current of about 70A.
▼There are two DrMos at the bottom, silk screen ISL99390, and the maximum stable output current of a single one is around 90A, which is very exaggerated.
▼There is an PWM controller , silk screen RAA229621, which is used to control these two DrMos and is responsible for powering the processor's SOC.
▼There are 9 DrMos on the upper side, and 7 DrMos on the left side are silkscreened 21472, with a maximum stable output current of 70A.
▼The two DrMos silkscreen ncp303160 on the left side, with a maximum stable output current of 60A. These two DrMos are responsible for powering the processor's core display, which is completely enough.
▼The 4Pin fan power sockets in the upper left corner of the motherboard have independent driver ICs.
▼There is a memory power supply circuit next to the memory slot, which can be clearly seen as simple as this. Because the latest DDR5 memory places part of the DC-DC circuit on the memory PCB, the motherboard only needs to provide 5V power supply, and the memory power supply circuit design can be much simplified compared to DDR4.
▼There are two chips at the rear of the front Type-C socket on the motherboard, a signal bridge conversion chip on the right, and the left is the ITE8851FN and USB PD3.0 controller, which provides support for this Type-C socket.
▼The two south bridge chips are very conspicuous, and they look very powerful.
▼The power supply of the south bridge is on the left, and there is a single-phase PWM controller and a driver IC at the rear, which drives the several upper and lower bridges next to it to work, providing power to the south bridge chip. There are four SATA3.0 interfaces on the right side of the Nanqiao chip. You can see that there is no master control chip, which means that these four SATA3.0 interfaces are native SATA3.0 interfaces, hehe.
▼There are many chips behind the IO interface at the back of the motherboard. HDMI video interface has a PS8209A behind it. This new product provides support for the HDMI2.0 interface. There is also a GL850G below, which is a USB 2.0 HUB chip that provides support for the four USB 2.0 interfaces behind the motherboard.
▼ The WIFI 6E wireless network card standard for motherboard is MediaTek MT7922A22M. This wireless network card supports the latest WIFI 6E, supports 2 x 2 Mu-MIMO, and supports 160MHz.
▼There are multiple bridges and conversion chips below to provide support for the USB3.2 interface behind the motherboard.
▼ There is also an ITX8851FN, USB PD3.0 controller here, which provides support for the Type-C interface at the back of the motherboard.
▼ Below is the main control chip of the wired Lan port, RTL8125B, which can provide 2.5G wired Lan.
▼The lower left corner of the motherboard, with a larger area on the upper surface, is the motherboard monitoring chip, used to detect various parameters of the motherboard. The chip below is a smaller area, the silk-print ALC897, which is a sound card chip, and the golden side is Nigikon's audio capacitor.
▼ Next to the M2 interface at the bottom of the motherboard, there is a motherboard BIOS memory chip with a capacity of about 32MB.
▼ There is also an IT5701E directly below the bottom M2 slot of the motherboard, which is probably also used to monitor the various parameters of the motherboard.
▼There are only some small components on the back of the motherboard, mainly patch capacitor and the like.
▼The lower right corner of the motherboard can be clearly seen that this board uses 8-layer board materials, which is still very good.
. Summary
Gigabyte's X670 AORUS ELITE AC motherboard is still very good overall. The appearance is quite beautiful. The front of the motherboard is covered with large areas of metal heat dissipation parts, and the shape and painting are very beautiful.The metal heat sink can also assist in heat dissipation. The power supply circuit part of the motherboard, the M2 slot part, and the south bridge part are all covered to ensure the stable operation of these places. In terms of materials used in
, Gigabyte's motherboard uses 16+2+2 phase power supply, among which the 16-phase 70A DrMos mainly supplies power to Vcore, the 2-phase 60A DrMos is responsible for powering Vgt, and the 2-phase 90A DrMos powers the SOC to ensure the stable operation of the processor. The materials used in this power supply circuit are very good, and it can easily cope with the stable operation of the flagship AMD 7000 series processors. In addition, the power supply circuit is covered with a huge metal heat sink, and there is a heat pipe between the two metal heat sinks, ensuring the temperature of the power supply circuit. In terms of
expansion, this motherboard is equipped with four M2 interfaces, one of which supports PCIe5.0 x 4, and supports a maximum of 25110 specifications. There are two front USB3.2 sockets in the chassis and one front Type-C socket in the chassis, which is not bad. The only thing that is not very satisfied with is that the sound card chip is only ALC897, and there are only three rear audio interfaces on the motherboard.
Thank you everyone!
