*Note: Correct ROP count is 56 for the GTX 970* Yes, that last 0.5GB of memory on your GeForce GTX 970 does run slower than the first 3.5GB. More interesting than that fact is the reason why it does, and why the result is better than you might have otherwise expected. Last night we got a chance to talk with NVIDIA’s Senior VP of GPU Engineering, Jonah Alben on this specific concern and got a detailed explanation to why gamers are seeing what they are seeing along with new disclosures on the architecture of the GM204 version of Maxwell.
For those looking for a little background, you should read over my story from this weekend that looks at NVIDIA's first response to the claims that the GeForce GTX 970 cards currently selling were only properly utilizing 3.5GB of the 4GB frame buffer. While it definitely helped answer some questions it raised plenty more which is whey we requested a talk with Alben, even on a Sunday.
