Geez. The chip itself is nearly as big as an entire MXM card. Temp differentials across the chip and plate will be interesting to see.Rtx5090 PCB, this is not reference model, it's for an AIB
512bit bus confirmed and 1x power connector
As you can see the chip is MASSIVE, along with 16 x 2GB memory and 40 phase VRM and the PCIE pin layout shows its PCIE 5
