NVIDIA finally responds to the GTX 970 memory issue after the recent 
problems using more than 3.5GB of Video RAM (VRAM). Currently the NVIDIA graphics card community claims that by disabling three SMMs on the GM204 -200 GPU which are on the GeForce GTX 970, memory becomes severely effected with poor performance in only using the last 0.5GB of VRAM. It has been reported that this issue was brought up in during the design and configured that the memory would be divided into 3.5GB and 0.5GB segments. 


NVIDIA releases their statement below:
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.
 
Here’s an example of some performance data:
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.

In front of calendar age adolescent has fresh information, in energetic age that child has strong information and in position that child has most grounded information about things. Our researchers have grown-up creating capacities.
