Circuit Board (PCB) Analysis
The GPU VRM is a two-phase design powered by an NCP81022 controller.
For the GPU voltage, a classic dual MOSFET configuration is used, provided by the Nikosem PK698SA and PK9168A, which are rated for 40 A.
The memory VRM is two-phase, too, and powered by a second NCP81022 controller.
For memory, a pair of Alpha & Omega AONR36366/AONR36368 is used for each phase, rated for 35 A.
The GDDR6 memory chips are made by Micron and carry the model number D9ZPP, which decodes to MT61K512M32KPA-16. They are specified to run at 2000 MHz (16 Gbps GDDR6 effective).
AMD's Navi 24 graphics processor is the company's smallest RDNA 2 chip. It is fabricated using a 6 nanometer production process at TSMC Taiwan, its transistor count is 5.4 billion, and the die size is 107 mm².
