Multiple sources around the world, as well as our own, are saying that NVIDIA will unveil their next-gen video cards in the coming weeks. With Computex right around the corner, this makes perfect sense.
We've already seen the company unveil its new Tesla P100 video card, powered by the new Pascal architecture, rocking HBM2 and the spiffy new 16nm FinFET process. The P100 features 15 billion transistors on the GPU itself, with another 135 billion transistors for the rest of the card - thanks to the incredible HBM2.
Most sites are still reporting that NVIDIA will call the new cards the GeForce GTX 1080 and GTX 1070, but I don't think we'll see this happen. I think we'll see NVIDIA move towards something like GeForce 10K, which sounds much better.
