NVIDIA Sells Two SKUs of each Turing GPU (a normal and OC model)
So a colleague website just posted this, and since the cat is out of the bag we might as well post it also. A while ago we noticed separated (two) GPU hardware IDs for the same Turning GPU. Let's call it an A and B model for each GPU. The one is a standard SKU, the other an OC version. And here is how that works.
So let's take the GeForce RTX 2080 Ti as an example, the GPU in there is a TU102. So basically NVIDIA offers two chips based on TU102, one is the TU102-300 and the other TU102-300-A. That A model is short for an OC SKU. So when a board partner is using the TU102-300 (and not TU102-300-A), then they are not allowed to factory tweak it. Thus such a product would end up at reference clock frequencies and would end up in the cheaper blower cooler style products right? Likely the better yielded GPUs end up as an A model.
Now here's why I wanted to write a news item on this: people can still manually tweak that non-A model. So you as a person could grab Afterburner or any tool of your preference to overclock yourself. Chances, however, are higher than the overclock might be less than the A model.
I hope that clarifies a thing or two. BTW TPU who reported this is spot on, we've verified this weeks ago already with many AIBs. And from what we learned, all of them are simply opting the A (OC) series GPUs.

The electric bill is not the major issue. The issue is how to keep it cool yet still quiet. 100W can be the difference between barely audible fan and jet taking off. A better and more expensive power supply is needed as well.

True but that also depends on the cooling solution

Hilbert, thank you for posting this article. It sounds to me as if Nvidia is being cautious with this GPU.

This was already happening for years, but now, instead of being AIBs making the selection of the best chips for certain versions, it's Nvidia itself. In the end, nothing changes for the consumer!
No chip will be blocked for OC, but cards with better cooling and better power design, will receive the more binned chips to overclock even better. Which make perfect sense, since the buyer of an Zotac AMP! Extreme for example, pay more for that than who buys a basic Zotac card.

To me, all this does is add a layer of binning from Nvidia. All of the AIB partners bin their best stuff and charge a premium for it. Could be that Nvidia is trying to prevent all those factory overclocked cards from AIBs that aren't actually stable. I had a 970 like that.
I only ever run mild overclocks on anything anymore so perhaps it's less an issue to me than some. If I even bother. My 4790K and 1070 have been stock for well over a year.
