... It was way back in 2011 that NVIDIA first talked about Maxwell, the next-gen CPU architecture coming after the current-gen Kepler. To reiterate, Maxwell, which is slated for a 2014 release, will offer significantly higher performance per watt than Kepler (roughly double) in addition to Unified Virtual Memory support. Today, however, Jen-Hsun revealed some details of the Volta architecture, coming after Maxwell. In addition to the new technologies offered in Maxwell, Volta will again approximately double performance per watt and feature Stacked DRAM. Anytime you have to take a signal off-chip and traverse a PCB and external memory bus before accessing DRAM, the signal degrades and must be slowed down. By using stacked DRAM, that signal can be kept much closer to the chip; in fact it will reside on the same package as the GPU. According to Jen-Hsun, Volta will offer 1TB/s of memory bandwidth to the stacked DRAM over its interface, which is more than 3X the bandwidth of NVIDIA’s current flagship GeForce GTX Titan. Jen-Hsun also revealed that the image of the stacked DRAM and Volta GPU die were ‘to scale’, for whatever that’s worth. No exact release date was discussed for Volta, but the roadmap slide suggests a 2016 timeframe. ... _______________________________________________ Beowulf mailing list, [email protected] sponsored by Penguin Computing To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
