Nvidia recently has updated their GPU chipset roadmap during GPU Technology Conference 2013.
The company’s CEO first highlighted “Maxwell” which will make its debut during 2014. Maxwell is intended to double the performance and have better performance-per-watt. Maxwell will feature unified virtual memory which will allow the CPU to use the GPU’s memory module as the system’s memory.
“Volta” doesn’t come with a tentative launch date, but the architecture will be using stacked DRAM technology which will allow upto 1 TB/s GPU memory bandwidth, nearly 700 GB/s more than what Titan is capable of.
