https://www.fjoddes.net/index.php/gigabyte-gives-amd-x570-the-full-aorus-treatment-itx-to-xtreme/ Motherboard vendors are betting big on the success of AMD's "Valhalla" desktop platform that combines a Ryzen 3000-series Zen 2 processor with an AMD X570 chipset motherboard, and have responded with some mighty premium board designs. GIGABYTE deployed its full spectrum of Aorus branding, including Ultra, Elite, ITX Pro, Master, and Xtreme. The X570 I Aorus Pro WiFi mini-ITX motherboard is an impressive feat of engineering despite its designers having to wrestle with the feisty new PCIe gen 4 chipset. It draws power from a combination of 24-pin and 8-pin connectors, and conditions power for the SoC with an impressive 8-phase VRM that uses high-grade PowIRstage components. A rather tall fan-heatsink cools the X570 chipset, with a 30 mm fan.
Connectivity options on the X570 I Aorus Pro WiFi are surprisingly aplenty. The sole expansion slot is a PCI-Express 4.0 x16, but the storage connectivity includes not one, but two M.2-2280 slots (reverse side of the PCB), each with PCI-Express 4.0 x4 and SATA 6 Gbps wiring. Four SATA 6 Gbps ports make for the rest of the storage connectivity. Networking options include 2.4 Gbps 802.11ax WLAN, Bluetooth 5.0 (Intel , and 1 GbE, all pulled by Intel-made controllers.
The X570 Aorus Elite is the most affordable X570 ATX board on display. It draws power from a combination of 24-pin and a single 8-pin EPS power connectors, conditioning it for the CPU with a 14-phase VRM. You still get some decent features such as two M.2 slots, both with PCI-Express 4.0 x4 wiring, one PCI-Express 4.0 x16 slot (the second one is gen 4.0 x4 and wired to the chipset), a rather premium onboard audio solution with ALC1220VB-Enhance CODEC; and 1 GbE driven by an Intel i211-AT controller.
The X570 Aorus Ultra belongs to that class of $200-ish motherboards such as the MSI Gaming Pro Carbon, which appeals to gamers who just want a high-end turnkey solution without having to drop in too much manual overclocking. It's based on the same exact PCB as the X570 Aorus Pro, including the same CPU VRM solution, but with a few premium bits that include 802.11ax WLAN + BT 5.0, a fin-stack heatsink over even the vSOC portion of the CPU VRM.
The X570 Aorus Master is where things get pretty serious. The CPU VRM is still 14-phase, but pulls power from two 8-pin EPS connectors, uses a super-expensive VRM controller supplied by Infineon marshaling PowIRstages, and fin-stack heatinks all around. Among the long slots are three PCI-Express 4.0 x16 (x16/NC/x4 or x8/x8/x4), with the third slot being wired to the X570 chipset. You get three M.2 slots with PCIe gen 4.0 x4 wiring.
The lineup doesn't end with the Aorus Master. That honor goes to the X570 Aorus Xtreme. This board is an absolute unit, featuring a 16-phase VRM that uses an expensive Infineon VRM controller, PowIRstages, and extremely high current chokes, while pulling power from two 8-pin EPS connectors. A metal shroud covers most parts of the board. The X570 chipset is passively cooled with a massive heatsink that sheds some of its heat onto the VRM heatsinks, the three M.2 SSD heatsinks, and a rear metal plate. Networking includes 802.11ax + BT5.0, one 10 GbE interface pulled by an Aquantia-made controller, and a second 1 GbE backed by an Intel i211-AT. The onboard audio solution is a tiny bit more premium than the Aorus Master, with a 130 dBA SNR variant of the ESS Sabre DAC.
Now these are some impressive motherboards ready for PCIe gen 4
