The X570 Aorus Xtreme shows us the goods with the heat sinks removed!

The VRM is in a 14+2 phase configuration, and it's a true 14 phase that doesn't utilize doublers, the new Infineon digital PWM controller (XDPE132G5C) supports up to 16 true phases (14+2). GIGABYTE states they gain 4% efficiency using this method. While that might not sound impressive, it's the same difference between 80 Plus Silver and 80 Plus Platinum power supplies, so it's a bigger deal than you might think.

Both the CPU VCC and SoC VRMs use Infineon's TDA21472, which is a 70A integrated power stage, and uses Infineon's latest technologies. The VRM in front of us here today might be one of the best we have ever seen, and with the heat sink and improvements in PCB copper, GIGABYTE really hit it out of the park.

The memory VRM is a single-phase controlled by an RT8120D PWM controller and PowerPAK MOSFETs in a two low-side one high-side MOSFET.
