NVIDIA Volta GPU to feature on-chip DRAM

Over at the NVIDIA GPU Technology Conference, NVIDIA CEO Jen-Hsun Huang shared details about the company's next-generation graphics chips. Early next year we can expect Maxwell, the successor to Kepler. This chip will introduce unified virtual memory, which means the GPU will be able to see the contents of the system memory, and vice versa. One of the benefits of this is that it will make programming the GPU easier, which should come in handy for GPGPU applications.

Maxwell's successor will be Volta, NVIDIA didn't share details about a possible launch date but 2016 is likely a good guess. NVIDIA touts stacked DRAM as the main innovation of Volta. Instead of relying solely on off-chip memory, the Volta GPU will include vertically stacked on-chip DRAM to enable much higher bandwidth. Huang claims the integrated memory achieves 1TB/s of bandwidth, over three times as much as the memory bandwidth of the GeForce GTX Titan!
