Circuit Board (PCB) Analysis
GPU voltage is powered by an expensive Infineon XDPE132G5D running with 13 power phases.
International Rectifier TDA21472 DrMOS chips are used throughout the card.
Memory voltage uses a 3-phase design controlled by an OnSemi NCP81022N 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.
