We would like to begin by thanking you for your patience while we investigated your inquiry regarding your NVIDIA product concerns. It is likely your product is under a replacement only return policy making the product ineligible for a refund return. Because of this, we want you to know that we have spent significant time speaking with NVIDIA to better understand the confusion regarding the specs associated with the video card. NVIDIA has worked with the manufacturers and recommended that you contact the manufacturer directly to discuss this further. The manufacturers are aware of this recommendation and willing to take your call to discuss your concerns. Please see the manufacturer phone numbers below.
Additionally, we are including some information provided to us by NVIDIA that might be helpful. We are also including a couple of links to technical publications that you may trust that further discuss this topic.
Information Provided by NVIDIA
The GeForce GTX 970 is equipped with 4GB of dedicated graphics memory. However the 970 has a different configuration of SMs than the 980, and fewer crossbar resources to the memory system. To optimally manage memory traffic in this configuration, we segment graphics memory into a 3.5GB section and a 0.5GB section. The GPU has higher priority access to the 3.5GB section. When a game needs less than 3.5GB of video memory per draw command then it will only access the first partition, and 3rd party 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. When a game requires more than 3.5GB of memory then we use both segments.
We understand there have been some questions about how the GTX 970 will perform when it accesses the 0.5GB memory segment. The best way to test that is to look at game performance. Compare a GTX 980 to a 970 on a game that uses less than 3.5GB. Then turn up the settings so the game needs more than 3.5GB and compare 980 and 970 performance again.
===============CHARTS=======================
On GTX 980, Shadows of Mordor drops about 24% on GTX 980 and 25% on GTX 970, a 1% difference. On Battlefield 4, the drop is 47% on GTX 980 and 50% on GTX 970, a 3% difference. On CoD: AW, the drop is 41% on GTX 980 and 44% on GTX 970, a 3% difference. As you can see, there is very little change in the performance of the GTX 970 relative to GTX 980 on these games when it is using the 0.5GB segment.
