Circuit Board (PCB) Analysis

GPU Voltage, VRM Configuration

GPU voltage is a massive 24-phase design managed by a Monolithic Power Systems MP2891 controller, which also handles memory voltage.


For the GPU voltage, Monolithic Power Systems MP86957 DrMOS chips are used; they are rated for up to 70 A output current each.

Memory Voltage, VRM Configuration

Memory voltage is a four-phase design, managed by the same MP2891 that's used for GPU voltage.


For memory, Monolithic Power Systems MP86957 DrMOS chips are used, again rated at 70 A.

Graphics Card Memory Chips

The GDDR6X memory chips are made by Micron and carry the model number D8BZC, which decodes to MT61K512M32KPA-21:U. They are specified to run at 1313 MHz (21 Gbps effective).

Graphics Chip GPU

NVIDIA's AD102 graphics processor is the company's flagship Ada Lovelace GPU. It's the world's first 5 nanometer GPU, built at TSMC Taiwan with a transistor count of 76.3 billion and a die size of 608 mm².
