Circuit Board (PCB) Analysis

The GPU VRM is 8-phase, controlled by an International Rectifier IR35217 controller, which is among the best controllers available on the market.


International Rectifier TDA21472 DrMOS chips are used for GPU voltage.


Memory voltage uses a two-phase design and is generated by an NCP81022 controller.


For memory, DrMOS components from Alpha & Omega Semiconductor 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 21 silicon is spread across a 519.8 mm² die area and packs 26.8 billion transistors. The pinkish-red tinge we saw on Navi 10 is gone.
