Circuit Board (PCB) Analysis

AMD is using a 12-phase GPU VRM design, which is powered by an expensive Infineon XDPE132G5D 16-phase VRM controller. For GPU voltage, a 12-phase VRM configuration is installed.


AMD is using International Rectifier TDA21472 DrMOS components on the Radeon RX 6800 XT, whereas on the RX 6800, they use chips from Alpha & Omega Semiconductor.


Memory voltage uses a 3-phase design controlled by an International Rectifier IR35217 controller.


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.
