Circuit Board (PCB) Analysis

GPU voltage is an 8-phase design, managed by a IRF 35217 controller.


GPU voltage on AMD is two separate rails. On one, OnSemi NCP302155 DrMOS chips with a 55 A rating are used, the other rail uses OnSemi NCP302045 chips with a 45 A rating.


Memory voltage uses a two-phase design and is generated by an NCP81022N controller.


For memory, 45 A OnSemi NCP302045 DrMOS chips are used.


The GDDR6 memory chips are made by Hynix and carry the model number H56G42AS8DX-014. They are specified to run at 2500 MHz (20 Gbps effective).


AMD's new Navi 33 graphics processor is a monolithic design, unlike Navi 31, which powers the RX 7900 Series. It is fabricated on a 6 nm process at TSMC Taiwan with a die size of 204 mm² and 13.3 billion transistors.
