GeForce GTX 970 Design Flaw Caps Video Memory Usage to 3.3 GB: Report

I read this on OCN right when it was posted... I thought, I am sure glad I went with the GTX980 :P
 
there has been shit loads of complaints on the nvidia forums since the 970 was launched. the issue has either been publicly found out or it is multiple issues.
the thought that a team of engineers are scratching heads over a gpu is laughable. not a robot or a space shuttle. at this point they are getting pressure to do anything they can to stop a recall but if they cant nvidia will just do what they have to and apologize.

Beat you to it :p If what they say as true, and you have to assume it is, it does make sense and doesn't sound like too much of a big deal to me frankly.
 
thats where QC matters, company like NVIDIA if can't pay for QC, then its shamef ul i guess. they already charging premium prices for there cards, from years now, especially kepler series. the 770/780/780Ti all were the most sell product past 1, 2 years.
 
o jeeze.. i can see where this is going :laugh: i was right they put pressure down the lines at least :laugh:
 
there's another problem with nvidia architecture since fermi that no one seems to talk about. It's about the number of ROPS these gpus can acces. I've only seen the kind of tests that reveal this on sites like harware.fr.
For example a gtx 970 only uses ~40/64 rops, a gtx 580 only 32/48, gtx 780 32/48, etc.

Perhaps they should rewrite the driver so that the desktop, secondary monitor and other lower priority tasks use that memory space, while the main portion is used for gaming and high performance tasks. Who needs 150GBps of memory bandwidth for their desktop?

Like I said, it hasn't affected me at all since I've owned the card so yeah it is kinda hard to be that upset about it.
 
haha my bad... it was tiny but still a little strange.

what will be really bad is if the 960 does the same thing.. check out what happens to the 960 in sleeping dogs.. http://www.pcworld.com/article/2872...view-maxwell-meets-pc-gamings-sweet-spot.html seems that the shit hits the fan and the 270x pulls nearly twice the frames when you tax the vram to its limits :eek:

What u smokin' ?

shhh it was tiny haha i guess if it would suggest anything at all is that the 960 has better memory management than the 760.
 
Here's the way I'd look at it. The architecture is designed to operate as the full chips, when you start cutting bits off the balance between the processors/schedulers/registers/controllers/etc. changes and as NV says, it does the same with the interconnects. The way the architecture is designed, assigns certain areas into blocks, each with their own components, buses, etc. and cutting one of the blocks away, or part of it, gimps the performance of that block. Now, the crossbars partially solve this, by allowing some intercommunication between the different parts of the chip, however, there is a tradeoff to be made, because more crossbars means more cost, and they are not utilized as much in a full chip configuration. A way to potentially alleviate this issue, is similar to what intel does with their extremely large server chips, using a ring bus configuration, however this has (AFAIK) not been implemented to a chip that has neither the size (talking GM200/GK110/GF110 here) or bandwidth requirements, so could result in being even worse than the current configuration due to extra die area necessitated for such a system. And I don't think the performance benefit will justify a ring bus architecture on the smaller chips.

What it comes down to is optimizations on the architecture level and tradeoffs they will most certainly have taken into account when designing the full and cut chips. They have spent way more R&D time on it than we have, and I'm sure they have a lot more resources to use too, so I don't feel we are in a position to question HOW they lay out their architecture. I am also quite sure that these kinds of issues exist with almost any architecture, especially with cut dies, both CPU and GPU (or any other processor for that matter).

BUT, and here is a big but (and it's underlined too, guess that makes it an important but...) I have to question NVidia's way of marketing this. OK, sure, there are 4GB of accessible to, and the memory bus operates at the stated speed, but I feel there should at least be a side note that not all of the memory is addressed at the stated speed. Then again, this complicates things for the less tech savvy, and results in more confusing numbers.

Welcome to the wonderful world of marketing!
I think you'd run out of superscript/asterisk notations if you fully tried to explain* the finer points of IC architectures. Both vendors tout DX12 support - Nvidia is careful to append their support with "API", while AMD's fine print reads (paraphrased) "at this time- based on known specifications". AMD were very quick off the mark in publicizing the FX series as the world's first desktop 8-core CPU, but declined to mention the shared resources and compromises involved that separate it from truly being 8 independent cores.
What it comes down to in most instances is how much the user is affected within the space between truth and claims.

* I've always found it astounding the vast number of buyers that don't even read the spec sheet, let alone the fine print and reasons behind it. The number of people who buy based on a few marketing bullet points seems to far outweigh those who research their prospective purchases. Maybe it's the nature of an industry manipulated by built-in obsolescence (or its illusion).

Sleeping Dogs is an AMD Gaming Evolved title tailored to GCN and heavily coded for post-process compute - something Kepler wasn't particularly well suited for

Ah, fellow ninja master of the control V technique :respect: I yet have to learn to use it alone and by itself only :p

I think it's the best they could do with this kind of asymmetric memory configuration, they get to use the greatest part of vram with full bandwidth most of the time ... when it needs full 4 GB they get that with 1-3% overall performance penalty.

a recall or a simple update might fix the issue. A recall perhaps...with a nice free upgrade to GTX 980 :)

A recall? LOL. Do you realize how expensive that would be? The profit margin on the card is less than the amount it would cost to pay for the shipping back to the manufacturer and send out a replacement. Then there's the cost to nVidia of replacing all those chips with new ones. If this issue can't be resolved with a software patch/driver update, nVidia is going to be spending hundreds of millions of dollars to fix this.
 
Nvidia why you do dis :cry:

But seriously I hope Nvidia look into this ASAP. :pimp:
 
Damn, I brought a Gigabyte GTX 970 4GB G1 Gaming Graphics Card as a part of a PC I will ship to my sister as a present. This is some what awkward...
