In a rather surprising report, Nvidia is apparently preparing an 8GB version of its flagship Geforce GTX 980 graphics card which should be landing on retail/e-tail shelves in November.
The report
comes from Hermitage Akihabara and has been picked up
by Wccftech.com, and suggest that while most single GPU configurations with 4GB of RAM might be enough for most games, recent push into 4K territory might need a lot more memory.
While AMD Radeon R9 290X can achieve much greater memory bandwidth due to its 512-bit wide memory interface, Nvidia's flagship is sort of limited by 256-bit memory wide interface but rather uses sotftware and color compression techniques in order to overcome that limitation.
Currently, there is no single GPU graphics card that can run any modern game at 4K resolution and high settings, mostly due to their 4GB memory limitations. Currently, 4K gaming is reserved only for multi-GPU configurations but if these early reports are true, both AMD and now Nvidia might have a single-GPU graphics card which will be able to cope with high resolution gaming.
