NVIDIA might be having some trouble filing the trademark for its next-gen Hopper GPUs but that doesn't hinder its development of the flagship GH100 die as the latest rumor from Kopite7kimi claims that the chip would measure around 1000mm2.

Currently, the biggest GPU under production is the NVIDIA Ampere GA100 which measures 826 mm2. If the rumor is correct, then NVIDIA's Hopper GH100 will go on to become the largest GPU design ever conceived, measuring around 1000mm2, easily topping the current monster GPUs by at least 100mm2. But that's not all, the die size in question is for a singular GH100 GPU die and we know that Hopper will be NVIDIA's first MCM chip design so considering that we get at least two Hopper GH100 GPUs on the same interposer, the dies alone would measure 2000mm2. All of this means that the interposer would be vastly bigger than what we have seen yet, considering it will pack several HBM2e stacks and other connectivity on board.
