Circuit Board (PCB) Analysis

A massive 23-phase VRM powers the GPU, highlighted in the red rectangles above. These are controlled by a Monolithic Power Systems MP29816 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.


Powering the 16 GDDR7 memory chips is a 6-phase VRM driven by the same Monolithic MP87993 controller that controls GPU voltage.


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


The GDDR7 memory chips are made by Samsung, and bear the model number K4VAF325ZC-SC28, they are rated for 28 Gbps.


The NVIDIA GB202 GPU at the heart of the GeForce RTX 5090 is massive. It is fabricated using a 5 nanometer "NVIDIA 4N" process at TSMC Taiwan (same process as Ada). The die measures 750 mm², and comes with a transistor count of 92.2 billion.
