[Twitter] Jen-Hsun introduces the new NVIDIA TITAN X - Page 175  

post #1741 of 3587

While looking at this youtube vid on the Pascal Titan X the author makes a point that the new Titan XP in his Logarithmetic projections would do approx 24059 in Firestrike.

[Youtube] Titan X Preview source

 

 

I took this one step further using nearly the same methods and asked what if we got the Full chip of 3840 cuda cores. And this is where I need your help as the figure seems low initially but i'm not sure. You guys are better at log math than i am, even with google search on excel functions :o

 

My graph looked like this: Titan X Black 3840 Cuda Cores using "only a Trendline in Excel".  Help 

 

 

I ask does this make any sense at all for a guess of a guess lol? Also if the full unblemished chip would only provide a marginal increase would it even be worth it to provide the full 3840 cores, for gamers...

Either not featuring the full number of cores is so they can hold something in their back pocket to release at a later date as a more powerful product.

... or ...

Their yields of GP102 are such that they cannot generate sufficient quantities with all 3840 cores operational to make supply of such a product viable. So they chose to reduce the requirement slightly so that the number of chips they yield with 3584 working Cuda cores give sufficient supply for the number products they expect to sell.

There is no where to put any more cores, past 3840, on the GP102 die. It's FP64 capabilities are already nearly completely stripped, along with virtually all of GP100's professional/HPC features.

The only thing a GP100 GeForce would offer over a GP102 is better FP64 and HBM2. It would probably cost a lot more, and not offer much in the way of improved gaming performance. A GeForce card for just FP64 would be an extremely niche product, far more so than past Titans.

It'd be the same thing as buying a Quadro for gaming, sure it's technically more powerful but it's going to suck if gaming drivers suck.

Architecture is the same, all they'd need to do is stick the GP100 hardware IDs in the GeForce drivers. Zero reason why the current core GTX 1080 drivers couldn't be used with any hypothetical Pascal part.

I doubt it. It's possible if it's only a Tesla compute part, but there will almost certainly be GP100 Quadros at some point.

You can't repurpose a part that lacks ROPs as a gaming part without a significant redesign. They aren't going to make yet another Pascal design for the 0.001% of the market that wants a 2500 dollar GeForce.

Either GP100 has all it needs to be an actual GPU and not just a compute accelerator, or GP102 is the biggest Pascal part that will ever be put on something with display outputs.

That would be another major redesign and isn't going to happen to Pascal.

I doubt they even left HBM support (PHYs/controllers) in GP102.

It's for sure this.

I just don't feel right paying a premium for a cut chip any more. Basically it's not the best Nvidia could offer on that die and not worthy of the Titan name regardless of the performance. With Die Shrink, new Architecture, and GDDR5X memory it's supposed to surpass the last generation so this is no surprise.


This right here. This is why people should be upset. I mean $1200 is worth being upset over, but the fact that this is nothing but a 1080Ti(basically) being a called a Titan should piss everyone off.

They're simply maximizing profits given the current market conditions (lack of competition). Use the Quadro rejects for this card. These are practically "free" GPUs; they would be written off otherwise.

I think we will see a big Pascal Titan (full GP102) and I also think we'll see a 1080 Ti. Give it some time. thumb.gif One caveat though; if AMD steps up this may change. If that happens it's possible we'll see a full GP102 1080 Ti just like the quick 780 Ti intro when AMD stepped up last time.

Your math is fine. Another issue comes with power consumption, which I think something we also forget - with HBM2, you can push the envelope of the thermal budget. A good reason this Titan XP is cut down is because of margin removed without the efficiency of HBM2. You can't maintain 3840 core part, with FP64, on such a strict budget with a stock cooler. This thing will run warm, like the Maxwell Titan X even with a cut down core because of the margin removed without HBM2.

I don't think we'll see a full GP102 - I mean, would an extra 256 Cuda cores really make that big a difference?. It's only an extra 7% A 1080 Ti is more of a possibility, because they'll go for the consumer double dip. If AMD steps up, that might change a little. Nvidia's possible ace-in-the-hole which I think they'll only produce if AMD put up a big enough challenge is GP100, but I recognise this might be a stretch. Otherwise, I think they'll be content to concentrate on Volta on 16nm for mid 2017.
