NVIDIA Reveals Next-Generation Volta GPUCategory: Video Cards

NVIDIA's annual GPU Technology Conference kicked off earlier today in San Jose, California, and CEO Jen-Hsun Huang has revealed the company's latest roadmap. Maxwell, which features unifed virtual memory and is the followup to Kepler, is still on the way, but now we know that Volta is due to arrive after Maxwell. Volta is designed to be even more energy efficient than previous chips and it uses something called stacked DRAM. Basically, it'll have DRAM on top of the GPU with silica sub-strate between the two, allowing for "a whole bunch of DRAMs stacked atop each other." There will be a hole through the silicon to connect each layer, with one terabyte per second of bandwidth. Jen-Hsun says it's the equivalent of moving all the data off a Blu-ray disc in 1/50th of a second and through the Volta chip.
Now, there's no telling when Volta is due to arrive and NVIDIA didn't include any ballpark dates besides 2014 for Maxwell. So whenever Volta does arrive it should knock the socks off of anything around it, but until then we just have to dream about that 1TB/s bandwidth.
