Nvidia Pascal GTX 1080 Features 8GB GDDR5X With 320GB/s Of Bandwidth, New Report Claims
At GTC 2016, Nvidia unveiled the Tesla P100, which is powered by their fastest GPU yet, the Pascal GP100. While the company didn’t talk about the consumer side of things during the event, we’ve been hearing rumors for a while now that Nvidia could launch its consumer grade GeForce graphics cards at this year’s Computex in June.
Also, a couple of days ago, we reported that Nvidia’s next gen Pascal GP104 GPU could feature 20nm GDDR5 memory from Samsung. The GP104 GPU is expected to power a range of graphics cards, including the GeForce GTX 1070 and GTX 1080.
According to a new report however, it seems like the chip maker could opt for the faster GDDR5X memory on some of its upcoming graphics chips, as well – which offers twice the bandwidth and capacity over the last gen GDDR5.
The report claims that the GP104-based GTX 1080 would feature 8GB of GDDR5X on a 384-bit memory bus for a total of 320GB/s of bandwidth. The GTX 1070 will however drop down to GDDR5 on a 256-bit memory bus with 256GB/s bandwidth.
For reference, the current gen GTX 980 Ti features 6GB of GDDR5 on a 384-bit memory bus with 334GB/s bandwidth, which means the upcoming GTX 1080 would have a similar memory bandwidth, but with the new Pascal architecture.
The next gen Nvidia Pascal architecture is built on 16nm FinFET process technology and is expected to enable a much reduced power consumption, as well as 2x performance per watt improvement over Maxwell.
The upcoming Pascal cards are rumored to cost between $600 to $1,100, and as mentioned in the start, could launch at Computex 2016 which runs from May 31 to June 4 in Taipei, Taiwan.
