NVIDIA Corp. has officially unveiled a new radically-changed GPU architecture known as Volta due sometime in 2016-2017.
Volta will take over the still upcoming Maxwell architecture – itself a successor to the current Kepler generation. The new GPU architecture will try to solve one of the biggest GPU bottlenecks – the always insufficient memory bandwidth.
NVIDIA plans to achieve this by installing high-speed stacked memory chips right onto the same substrate the graphics processor is made from. The memory chips will be directly connected to the GPU and will offer extremely fast memory access as well as tremendous bandwidth compared to today’s solutions. As an example the fastest current single-chip graphics card – the GeForce GTX Titan – offers memory bandwidth of 288 GB/sec while Volta will offer memory bandwidth of 1 TB/sec and up.
NVIDIA however failed to offer more details on Volta but given its timeframe of 2016-2017 more details will become known along the way.
