The GeForce GTX 970 and GTX 980 both standard versions equipped with 4 GB of video memory, but soon awaits us influx upstream versions at double dose of memory. Is it a response to competitive Radeon R9 290X 8GB version?
GTX 970 and GTX 980 getting their 8GB memory variants
For now, both are available in 4Gb memory chips (32x 128Mb) GDDR5 32-bit interface, which together just 4 GB of GDDR5 memory and 256-bit bus. The specification provides support for the bone produced by the company Elpida, Hynix and Samsung, but the vast majority of the models are based on Samsung candies.
It is also worth noting that models of the GeForce GTX 900 series are using an optimized memory architecture that does not require so high bandwidth between the core and video memory – compared to the previous generation Kepler could thus be reduced by as much as 17 – 29%. After all, games are becoming more and more demanding and the players decide to use monitors with increasing resolution. As a result, manufacturers are considering to offer models with double the dose memory.
The Maxwell GM204 graphics processor has available 256-bit GDDR5 memory controller, thus doubling the video memory will be a little more complicated than in the case of a competitive Radeon R9 290X with 512-bit bus. Most manufacturers will most likely opt for the use of a memory chip with twice the capacity (8 GB instead of 4 GB) – these modules no longer available by Hynix, but from this quarter Samsung will begin to produce them.
GeForce GTX 970 and GTX 980 version with 8 GB of GDDR5 memory with 256-bit should appear at the end of the first or in the second quarter of this year. These models are noticeably more expensive than the standard version, but we do not know the specific prices.
