The obtained results showed that it is not yet the time for graphics accelerators equipped with 2GB of local video memory and it is unclear if this moment comes any time soon. It is obvious that 1GB of video memory is currently the de-facto standard for pretty high-performance gaming solutions, because in most cases they outperform the same solutions equipped with only 512MB of memory quite significantly. 2GB of memory may only be beneficial in extreme resolutions like 2560x1600 or higher, for which the graphics cards of the same class as GeForce GTS 250 do not have sufficient GPU performance or memory subsystem bandwidth.
Just look at the summary charts below and you will be able to draw a sad conclusion that 2GB of video memory onboard the Gainward graphics accelerator we talked about today is just another marketing trick that doesn’t have any real practical value for the gamers.
The biggest advantage it ever gets over GeForce GTS 250 1GB makes only 6% in Сrysis Warhead and Enemy Territory: Quake Wars in 1920x1200 resolution. The average performance gain is less than 1% in up to 1680x1050 resolutions inclusive and is barely past this mark in 1920x1200, so it can actually be neglected. Especially, since it doesn’t provide a sufficient advantage in any of the games, so that the user could feel it without having resorted to testing tools like Fraps.
