Jen-Hsun Huang Apologizes for GTX 970 Fiasco

Quote:Hey everyone,

Some of you are disappointed that we didn’t clearly describe the segmented memory of GeForce GTX 970 when we launched it. I can see why, so let me address it.

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.

Since then, Jonah Alben, our senior vice president of hardware engineering, provided a technical description of the design, which was captured well by several editors. Here’s one example from The Tech Report.

Instead of being excited that we invented a way to increase memory of the GTX 970 from 3GB to 4GB, some were disappointed that we didn’t better describe the segmented nature of the architecture for that last 1GB of memory.

This is understandable. But, let me be clear: Our only intention was to create the best GPU for you. We wanted GTX 970 to have 4GB of memory, as games are using more memory than ever.

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.

How sincere was he? Nvidia still lists the 970 as a 4 GB card with no caveat: http://www.geforce.com/hardware/desktop-...ifications

There is 4gb on the card and all 4gb is usable.

They would have to put a crossbar or ringbus on the L2 caches to do any better and that would cost more silicon than they had to play with at 28nm as well as be a lot more complex.

I certainly cannot complain about the way my 970's perform and I have them in SLI which makes the problem even worse if you believe the bleatings of the FanATics and AMD PR.

If I were you I would be looking to buy a 4k TV with your hardware. Are you biding your time until they have HDMI 2.0?

I will wait until they have HDMI 2.0 (properly working HDMI 2.0, not just checkmark HDMI 2.0), 60 hz and the price drops to the same level as my Hisense cost me.

Really I'd probably want DP or DVI on the TV as well, since I'm not confident HDMI of any flavor can produce the best quality computer image on a TV, having tried both HDMI and VGA on my Hisense (VGA wins hands down).

I'm perfectly content with 1080p plus SG:SSAA for now.

Yes, the TVs we have are really ideal in terms of price, specs, and size. Eventually I would like something bigger, maybe a 70" with 4k. You have too much GPU power though. You would really benefit from 4k.

No such thing as too much GPU power even at 1080p what with newer games demanding more performance, SG:SSAA etc and me liking a decent frame rate maintained.

I don't understand why you like so much AA. I can barely notice a difference beyond 2xAA. Beyond 4xAA I see no difference at all and I'm perfectly happy with SMAA.

You are doing it wrong then. SG:SSAA done properly combined with a negative LOD makes games look exquisite.

I'm sure it looks nicer but to me it's not worth the extra $400 worth of GPU power that you need in order to do it.

To me it is.  Everyone is different.  I'd rather be overpowered than underpowered.  and it's not like I'm running Titan Blacks or anything stupid, just cost effective 970's.
