Circuit Board (PCB) Analysis

GPU voltage uses eight phases and is powered by an International Rectifier IR35217.


OnSemi NCP302155 DrMOS chips are used for GPU voltage; they are rated for 55 A.


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 chips are made by Samsung, carry the model number "K4ZAF325BM-HC16," and are rated to run at 16 Gbps.


Built on the same TSMC N7 (7 nm) node as Navi 10, the Navi 23 silicon is spread across a 237 mm² die area and packs 11.6 billion transistors. The pinkish-red tinge we saw on Navi 10 is gone.
