Circuit Board (PCB) Analysis

GPU voltage is powered by the expensive Infineon XDPE132G5D running 14 power phases.


International Rectifier TDA21472 DrMOS chips are used for GPU voltage.


Memory voltage uses a three-phase design and is generated by an IRF35217 controller.


For memory, TDA21472 DrMOS chips are used, too.


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.
