Circuit Board (PCB) Analysis

An 11-phase VRM powers the GPU, highlighted in the red rectangles above. These are controlled by a uPI uP9512R voltage controller.


All GPU power phases use Monolithic MPS MP87993 DrMOS with a rating of 50 A.


Powering the six GDDR7 memory chips is a 3-phase VRM driven by a uPI uP9529Q voltage controller.


Just like GPU, the memory is handled by Monolithic MPS MP87993 DrMOS with a rating of 50 A.


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


The NVIDIA GB205 GPU at the heart of the GeForce RTX 5070 is much smaller than the chip used on the RTX 5080 and RTX 5090. It is fabricated using a 5 nanometer "NVIDIA 4N" process at TSMC Taiwan (same process as Ada). The die measures 263 mm², and comes with a transistor count of 31.1 billion.
