RTX 4090 PCB design leaks: NVLink and 16-pin power connectors
When NVIDIA launched the RTX 3090 Ti, it was revealed that the PCB was preloaded for the RTX 40 series high-end cards, so the new PCIe Gen5 16pin connector was used, and the PCB could be directly connected to the RTX 4090 or RTX 4080.
Recently Igor’sLAB released a PCB design that is said to be the next generation of NVIDIA. This one is used for the AD102 core. This PCB shows that there are four outputs, 3 DP and 1 HDMI, but it is impossible to judge whether there is DP2.0. In addition, you can also see the NVLink, which may be used by the RTX 4090, after all, NVIDIA is only open to high-end cards with this support.
The power supply part is a single 16-pin power connector, but it is too early to speculate on the power consumption of the RTX 4090, but the highest-end RTX 4090 Ti or a new TITAN may be at 600W. There are two types of RTX 40 high-end PCB numbers currently exposed, PG139 and PG136. The PG139 adopts a V-shaped design, which is the same as the RTX 30 Founders Edition models, while the PG136 is a normal rectangular design, which is used in most special and overclocking versions.
