“We invented a new memory architecture in Maxwell. This new capability was created so that reduced-configurations of Maxwell can have a larger framebuffer – i.e., so that GTX 970 is not limited to 3GB, and can have an additional 1GB. GTX 970 is a 4GB card. However, the upper 512MB of the additional 1GB is segmented and has reduced bandwidth. This is a good design because we were able to add an additional 1GB for GTX 970 and our software engineers can keep less frequently used data in the 512MB segment.
Unfortunately, we failed to communicate this internally to our marketing team, and externally to reviewers at launch.”
So they tried to push the boundaries with as little as possible, resulting in a very fast and usable 3.5GB VRAM, but failed to tell anyone outside of the company of this groundbreaking memory architecture; something that could have played so well to their advantage has seemed to have backfired.
“The 4GB of memory on GTX 970 is used and useful to achieve the performance you are enjoying. And as ever, our engineers will continue to enhance game performance that you can regularly download using GeForce Experience. This new feature of Maxwell should have been clearly detailed from the beginning. We won’t let this happen again. We’ll do a better job next time.”
Good guys NVIDIA for admitting defeat, let’s hope future driver updates will increase the speed of the last 512mb.
Have you returned or received any form of refund for your GTX 970? Are you content with the performance and think this has been blown massively out of proportion by a small population? Let us know on Facebook and our Forums.
Thanks to NVIDIA for sharing this with us.
