NVIDIA's GeForce RTX 4090 graphics card's reference PCB has allegedly been leaked and detailed by Igor's Lab once again.

Back in March, Igor Wallosek of Igor's Lab posted what was then assumed to be a block diagram of the NVIDIA GeForce RTX 4090's PCB. It was stated that the GeForce RTX 3090 Ti had been a crucial learning curve for NVIDIA and its AIB partners to ready themselves for the next-gen Ada Lovelace GPU lineup featured on the GeForce RTX 40 series.
