Well ASUS was the first to show off a motherboard designed for AMD’s upcoming ThreadRipper high-end desktop (HEDT) processors, but at AMD’s event there were a few more on hand. These are AMD socket SP3r2 (LGA 4094) motherboards. All of these boards feature eight DDR4 memory slots, up to three PCI-Express 3.0 x16 slots with x16 wiring, taking advantage of the 64-lane PCIe root complex, and a forth slot splitting away x8 lanes from the third slot.
The first board we see is the ASRock X399 Fatal1ty Gaming 9. This board has the full four x16 slots, all of which are wired to the CPU, eight DDR4 DIMM slots, 32 GB/s U.2 and M.2 connectivity, and eight SATA 6GB/s ports.
Next up is the ASRock X399 Taichi, which looks to be based off the same PCB as the Fatal1ty Gaming 9, but with different heatsink designs and a black / white color scheme. Both of these boards feature 802.11ac WiFi plus Bluetooth 4.1. There are also three wired network interfaces, one of which is 10 Gigabit.
The last board we see is the Gigabyte X399 Aorus Gaming 7. Here you have a total of five PCI-Express slots, at least three M.2 slots, one of which is covered by a cool heatsink, and eight SATA 6GB/s ports. It looks like you’ll also get RGBs on the memory slots, which are metal reinforced as well. The board will come with Gigabyte’s highest on-board audio solution that features ESS Sabre DAC, and the highest grade audio capacitors.
One interesting thing is that all three of these boards only use a single 8-pin EPS connector for power to the CPU. Could this mean that AMD would beat Intel with HEDT efficiency? Only time will tell!
