NVIDIA shows the PCB design of the RTX 4090 Founders Edition
NVIDIA released a new generation of GeForce RTX 4090 / RTX 4080 series graphics cards, using GPUs based on the Ada Lovelace architecture and TSMC’s custom 4nm process, coupled with new technologies such as the third-generation RTX light tracking architecture and DLSS 3, the performance has been greatly improved.
As in the past, Nvidia also unveiled new Founders Edition graphics cards, while Nvidia also showed off the PCB design of the GeForce RTX 4090 Founders Edition, made a brief introduction, and disclosed some features of the new product.
The GeForce RTX 4090 Founders Edition features the same compact design on the PCB as the previous generation RTX 3090 Ti Founders Edition and a very similar layout. It is equipped with a 23-phase power supply, of which 20 phases are used for GPU chip power supply, and the remaining 3 phases are responsible for video memory power supply. Nvidia says the new graphics cards have better power transient management. The power supply will be more stable, and a single 12+4Pin 12VHPWR interface can get a maximum power supply of 600W, but the default is 450W at this stage, and the existing power supply can work normally through the adapted cable (8Pin x3/4 transfer). ATX 3.0 power supply is definitely required.
GeForce RTX 4090 Founders Edition uses a new version of the cooling fan. Nvidia says it tested 50 new fan designs before choosing this cooling fan, which provided 20 percent more airflow than the one equipped with the RTX 3090 Ti Founders Edition. In addition, Nvidia has redesigned the vapor chamber around the GPU and memory chips, and the bottom plate in the VRM component area has also been revised. While the GeForce RTX 4080 16GB Founders Edition is positioned lower, it shares the same cooler design.
