Our take on the NVIDIA RTX 4090 48GB GDDR6X Graphics Card

A modified RTX 4090 with 48GB of GDDR6X memory, aimed at AI researchers and professionals who need large VRAM for training and inference. It offers double the memory of a standard RTX 4090 but uses a blower-style cooler and may have limited official support. Compared to datacenter GPUs like the A6000, it provides similar memory capacity at a lower cost but with fewer guarantees.
