Circuit Board (PCB) Analysis
GPU voltage is handled by a 4-phase VRM driven by a Richtek RT8845A controller
Sinopower 4507NH and 4503NH discrete MOSFETs are used for the GPU phases, these are rated for 60 A.
Memory voltage is a single-phase design, and handled by a buck controller.
For memory, the Sinopower 4507NH and 4503NH discrete MOSFET combo make a comeback, rated for 60 A.
The GDDR6 memory chips are made by Hynix and carry the model number H56G42AS6DX-014. They are specified to run at 2250 MHz (18 Gbps effective).
NVIDIA's AD107 graphics processor is the company's smallest Ada Lovelace GPU. It is built using a 5 nanometer process at TSMC Taiwan, with a transistor count of 18.9 billion and a die size of 156 mm².
