NVIDIA RTX 4090 public version PCB announced

NVIDIA has now announced the PCB design of the RTX 4090 public version. Overall, the PCB of the RTX 4090 public version adopts a similar design to the previous generation, with a V-shaped notch. There are also some minor changes, such as relocated capacitors on the RTX 40 models, and cutting out NVLink, but the layout of GDDR6X memory and VRM has not changed.

According to reports, the RTX 4090 has a 20+3 phase power supply (GPU/memory) with better transient voltage management, which should limit power excursions. The PCB uses the latest 12VHPWR power connector, with a theoretical power supply of 600W, but currently, NVIDIA partners have announced a default TDP of 450W, but some people suggest that the TDP of the dual BIOS setting is higher.

The NVIDIA RTX 4090 will be available on October 12, and the RTX 4080 will be available in November.
