Circuit Board (PCB) Analysis

The GPU VRM is a 4+1-phase-design controlled by an OnSemi NCP81022 controller.


Vishay SiC632A DrMOS chips are used for GPU voltage.


The memory VRM is 2-phase and managed by a second OnSemi NCP81022 controller.


For memory, Vishay SiC632A DrMOS chips are used, too.


The GDDR6 memory chips are made by Samsung and carry the model number K4ZAF325BM-HC18. They are specified to run at 2250 MHz (18 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.
