"It Won't Happen Again:" NVIDIA CEO Breaks Silence on GTX 970 Controversy

In the wake of bad PR, and a potentially expensive class-action lawsuit over the GeForce GTX 970 memory controversy, NVIDIA CEO Jen-Hsun Huang wrote a candid letter addressed to everyone concerned, explaining in the simplest possible language what went wrong with designing and marketing the chip, how it doesn't affect the design-goals of the product, its quality or stability, and how it could be misconstrued in a whole different ways.

Huang's explanation of the issue isn't much different from the one we already have, but bears the final stamp of authority from the company, especially with the spate of discrepancies between what NVIDIA representatives post on GeForce forums, and what ends up being the company's position on certain things. Huang's letter signs off with "we won't let this happen again. We'll do a better job next time."

The transcript of Huang's letter follows.

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.

Jen-Hsun

Dear Jen-Hsun,
You can say sorry all you want but it does knot change the fact that you false advertised and the value of my 970 has fallen and it stutters like hell at 1440p. 25%+ partial refund or full refund for this bulls***. I don't believe you guys mess up those crucial specs and hope you guys pay for it. Its not ok to do what you did.

Cordially,
Juan

RealNeilI'm not sure that huge amounts of memory will help unless GPU's memory ~bandwidth~ gets a wider highway for data throughput.
Double the memory of existing cards doesn't generally fully utilize the resource. It is more advertising and marketing opportunity. Double the memory but adding no increase in back end raster ops just moves the bottleneck from the framebuffer to the render. The only real advantage is that large textures can be held, which is often less an advantage for the 6GB/8GB card than it is a hobbling of the 3GB/4GB card...i.e., you're making the larger framebuffer card look better by choking the standard card.
RealNeil8GB NVIDIA based GPUs are not even listed for sale at Newegg.com right now, but I know they exist. (Probably expensive as hell)
You probably won't see them until Nvidia needs a marketing push ( that is to say AMD releases a comparable competitor and Nvidia needs to reply). Chances are the 8GB versions will sport 8Gbps IC's, which with colour compression factored in should equate to a nominal 50% improvement in bandwidth

heydan83Yes, and if that continues the same, we will need at least 6GB more quickly than anyone though...
I don't think so. The Ultra-HD textures don't make a big difference during actual gameplay, in fact the difference isn't even noticeable when you're actually playing.

The areas where you need more than even 3GB right now is stupid situations that won't affect 99.99% of people.

Bugsy004Has anyone returned their GTX970?
At least 10 000 people are against nvidia in the class law suit. :)

And that's very nice.

You mean this one? If that's the case then it's just people signing up. It means neither that 10K people have done so, nor that those people necessarily owned a GTX 970.
The fact that the petition has had some people sign 100+ times (and publicize that they did), and requires no proof of card ownership just proves that while some people undoubtedly are affected, Change.org petitions tends to attract a lot of trolls, marketeers, armchair activists, and sceptics all eager to wage some PR war outside the confines of tech blog sites.

HumanSmokeAnd yet, AMD's next flagship, the 390X is set to arrive with a 4GB framebuffer. So is the prediction of 4GB+ wrong, or are AMD shooting themselves in the foot, or are they making some serious compromises with color compression and hoping that non-Gaming Evolved partners scale back on use of uncompressible data (like that is going to happen on TWIMTBP titles if GM 200 arrives with 6GB of GDDR5)?
First Im not an amd fanboy Im not defending them, so if you think I will argue your comment you´re wrong, maybe your´re right will see what happen... I don´t know why fan boys keep bringing amd to the conversation, we´re talking about nvidia selling with lies...

This has nothing to do with fanboyism. It has to do with one of the two primary graphics cards makers deciding that 4GB is sufficient for next generation gaming. If they believe this to be so, doesn't that imply that this is indeed the case? or do you know something that the world's second largest producer of discrete graphics doesn't? After all, you're the one making pronouncements. I'm just trying to understand how you came by this belief
heydan83Yes, and if that continues the same, we will need at least 6GB more quickly than anyone though...
Awesome debating technique you have though....call people fanboys rather than explain how the you arrived at a conclusion. Way to get out of having to explain. :shadedshu:

newtekie1Not likely. It handled the top AAA titles today on the highest possible settings with 4k. If I have to turn off AA when running 4k I won't be too upset.

Also, the 1.5GB on the GTX580 was enough, in fact I had SLI 470s with 1.25GB. They worked perfectly fine, the memory amount wasn't an issue during their lifespan.
Fanboy alert. I actually run 4k games maxed out setting with no AA and 970Sli failed where 295X performed well. 970 is limited to 1080p only anything higher and folks have a high chance of going over 3.5GB, stuttering and lagging all over. Even techspot recognized the issue and are calling the 970 3584+512MB. 512 being the fake illusionary memory part.

All the way up until the 295x2 overheats, throttles, and framerates go to absolute shit, right?

You make statements like that and you're calling other people fanboys?!?

Here is the thing you may have missed... it doesn't ALWAYS happen over 3.5GB It would only happen if whatever minimally used data that is stored in that 512MB portion gets accessed a lot.

I had one, reviewed it, played games (BF4, Grid Autosport, Return to Castle Wolfenstein) at 2560x1440p with no visible issues.

I think the truth lay somewhere in between your apocolyptic account and the its all rosey crowd.

Surely you meant Wolfenstein: The New Order. You could run Return to Castle Wolfenstein on a potato today and iirc 800X600 was the max resolution (Circa 2001). Great game though with some cool mods. I had a lot of fun with it. Dammit, now I want to download it and play it again. I will never get to my new games this way. :(

Ha-Ha!
There are plenty of cool older games that still call out to me. Return to Castle Wolfenstein is one of them.

ROFLMAO... surely I did.. Was thinking back to my original Xbox days apparently... LOL!
