NVIDIA is planning to introduce a revolutionary new idea involving a traversal coprocessor and a dual-sided PCB with its RTX 3090 GPU (and family) according to a video by Coreteks. What this essentially means (if it turns out to be true) is that the upcoming graphics cards like the RTX 3080 and RTX 3090 will feature a dual-sided PCB with the GPU core on one side and a second co-processor on the other side. I do want to make it clear that I have no idea if this is true or not and it is only being posted because it has technical merit and Coreteks has proven to be reliable in the past. All that said, this post is still very much a rumor and copious amounts of salt, while not good for your health, are highly recommended.
