Someone has leaked a bare board for the Ampere GA102-based GeForce RTX 3090 graphics card, the upcoming flagship model featuring 5248 CUDA cores and 24GB of GDDR6X memory.
This board features both the irregular shape (reserved only to NVIDIA’s Founders Edition) and a new NVLink SLI finger that we discussed earlier. The board clearly shows 12 memory modules on each side, including the one placed right above the PCIe 4.0 slot. A dual-sided memory will allow this board to feature up to 24GB of memory. The RTX 3080, also based on GA102 GPU, should only need 10 single-sided modules and 20 dual-sided modules for the rumored 20GB variant later.
NVIDIA will launch its GeForce RTX 3090, RTX 3080, and RTX 3070 graphics cards this month. The announcement is taking place in less than 12 hours from now.
