Circuit Board (PCB) Analysis
For the GPU, PowerColor is using a mammoth 16-phase VRM controlled by an expensive Infineon XDPE132G5D controller.
International Rectifier TDA21472 DrMOS components are used throughout the VRM.
Memory voltage uses a 3-phase design controlled by an International Rectifier IR35217.
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 the "Navi 10" is gone.
