On GTX 980, Shadows of Mordor drops about 24% on GTX 980 and 25% on GTX 970, a 1% difference. Then turn up the settings so the game needs more than 3.5GB and compare 980 and 970 performance again. Compare a GTX 980 to a 970 on a game that uses less than 3.5GB. The best way to test that is to look at game performance. We understand there have been some questions about how the GTX 970 will perform when it accesses the 0.5GB memory segment. When a game requires more than 3.5GB of memory then we use both segments. When a game needs less than 3.5GB of video memory per draw command then it will only access the first partition, and 3 rdparty applications that measure memory usage will report 3.5GB of memory in use on GTX 970, but may report more for GTX 980 if there is more memory used by other commands. The GPU has higher priority access to the 3.5GB section. To optimally manage memory traffic in this configuration, we segment graphics memory into a 3.5GB section and a 0.5GB section. However the 970 has a different configuration of SMs than the 980, and fewer crossbar resources to the memory system. The GeForce GTX 970 is equipped with 4GB of dedicated graphics memory. It would not take long before Nvidia now responded in public: But once the train gets rolling, it’s hard to stop right ? They cherry picked three US sites to explain the problem, we however have been bypassed from the issue ever since the very beginning.

From there on things escalated rapidly, the Nvidia forums got under attack from their customer base and Nvidia went into full damage control. But regardless of what anybody thinks of it, it did place the finger precisely at a sore spot. There has been discussion about the validity of that application. The problem persisted to display itself in our forums from end-users though, and just before the weekend a small CUDA application was released that showed weird behavior in the graphics subsystem. Three weeks ago even yours truly dismissed the issue, as once I loaded op the latest COD I could see 4 GB graphics memory being used, without any performance issues. The initial problem was hard to detect, and really. Three weeks ago here on users in our forums started to report oddities with their GeForce GTX 970 graphics card, the card ran out of memory at 3.5 GB, not utilizing anything higher or reports of stutters in high graphics memory usage.
It has been an interesting week with all the hype on the GeForce GTX 970 with what now is know as a crippled memory sub-system.
