Circuit Board (PCB) Analysis

GPU Chip Voltage Controller
GPU Voltage, VRM Configuration

The GPU VRM is 6-phase, controlled by an International Rectifier IR35217 controller, which is among the best controllers available on the market.

Memory Chip Voltage Controller

A second IRF IR35217 is used to manage memory voltage. Here, a two-phase design that's spread out a bit over the PCB is used.

Graphics Card Memory Chips

The GDDR6 memory chips are made by Micron and carry the model number D9WCW, which decodes to MT61K256M32JE-14:A. They are specified to run at 1750 MHz (14 Gbps GDDR6 effective).

Graphics Chip GPU

AMD's new Navi 10 graphics processor is their first chip to use the new RDNA architecture. It is produced on a 7 nanometer process at TSMC, Taiwan and has a transistor count of 10.3 billion with a die size of 251 mm². Do note the color of the GPU silicon in the second picture—it really is that color. It only looks black in the first photo because the camera lens is sitting right above it, resulting in a black reflection.
