Circuit Board (PCB) Analysis

GPU voltage is powered by an expensive Infineon XDPE132G5D running with 16 power phases.


The International Rectifier TDA21472 DrMOS chips for the GPU.


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


For memory, IRF TDA21472 chips are used, too.


AMD "Navi 21" relies on an external USB 3.2 controller for the USB-C port, supplied by Cypress Semiconductor and labeled "CYPD5137-40LQXI." This controller puts out 10 Gbps USB 3.2 Gen 2, DisplayPort passthrough, and 27 W power delivery.


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.
