Circuit Board (PCB) Analysis

GPU Voltage, VRM Configuration
GPU Chip Voltage Controller

A 10+3 phase VRM powers the GPU. It is managed by a Monolithic Power Systems MP2868A controller.


All GPU power phases use Monolithic MPS MP87993 DrMOS. These are new, we don't know their current rating. The "9" could suggest 90 A.

Memory Voltage, VRM Configuration
Memory Chip Voltage Controller

Powering the GDDR6 memory chips is a 3+1 phase VRM driven by a second Monolithic Power Systems MP2868A controller.


Just like GPU, the memory is handled by Monolithic MP87993 DrMOS chips.

Graphics Card Memory Chips

The GDDR6 memory chips are made by Hynix, and bear the model number H56G42AS8DX-014, they are rated for 20 Gbps.

Graphics Chip GPU

The AMD Navi 48 GPU at the heart of the Radeon RX 9070 XT is a monolithic die. It is fabricated using a 4 nanometer N4P process at TSMC Taiwan. The die measures 357 mm², and comes with a transistor count of 53.9 billion.
