Circuit Board (PCB) Analysis
GPU voltage is powered by the expensive Infineon XDPE132G5D running 17 power phases.
International Rectifier TDA21490 DrMOS chips are used for GPU voltage. Note that these are rated for 90 A, whereas the chips on other RX 6900 XT cards are rated for 72 A only.
Memory voltage uses a four-phase design and is generated by an IRF35217 controller.
For memory, TDA21472 DrMOS chips are used.
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.
