Could Nvidia have a faster/cheaper RTX 3090-like product in the works?Micron has already confirmed that they have 21 Gbps GDDR6X chips and that the company has 2GB/16Gb GDDR6X memory in the works. This fact alone has gotten us to consider the future of Nvidia's Ampere architecture. 

What if Nvidia decided to create an RTX 3090 Ti or RTX 3090 Super graphics card? What would Nvidia need to do to increase the performance of its upcoming RTX 30 series flagship? To us, the answer seems simple, change the RTX 3090's memory configuration. 

Our hypothesis is that Nvidia will want to move to Micron's 2Gb memory modules whenever they become available in large quantities. This will allow Nvidia to create a 24GB RTX 3090 class product with half as many memory chips. This change should enable Nvidia to maintain the high capacities any future RTX 3090 class offering while powering fewer memory modules, which will allow more power to be pushed to other areas of the graphics card. 

If Nvidia moved to 2GB/16Gb GDDR6X memory with 21Gbps speeds, the company would be able to offer over 1TB/s of memory bandwidth across 12 GDDR6X memory chips. If this also allows Nvidia to shift more power to their Ampere  GA-102 core, this should also allow Nvidia to boost the clock speeds of newer Ampere offerings. 

A side benefit of 2GB GDDR6X memory chips is that they will reduce the manufacturing complexity of future RTX 3090-class products, as fewer memory chips will need to be precision mounted during the manufacturing process. This alteration will slightly minimise manufacturing time and lowers the number of steps that are required to produce these graphics cards. These changes will reduce production costs and potentially lower product defect rates. 

With an RTX 3090 Ti/Super, it is always possible that Nvidia will be able to enable more SMs to increase the CUDA core counts of refined GA-102 variants. Add that to Nvidia's potential use of faster GDDR6X memory and the prospect of lower VRAM power consumption, and Nvidia has the potential to release a much more powerful configuration of their RTX 3090.
With 2Gb GDDR6X memory chips being unavailable, Nvidia was forced to utilise twenty-four 1GB GDDR6X memory chips to create the RTX 3090's huge frame buffer. The addition of 2GB GDDR6X chips to the market could also allow manufacturers to develop 20GB versions of Nvidia's RTX 3080 in 2021. 

While Nvidia RTX 3090 graphics card is already an incredibly powerful product offering, there is a change that the company has something more powerful in the works. That said, such a graphics card relies on GDDR6X memory chips that currently do not exist, at least in mass manufacturing quantities.

    I doubt very much Nvidia is going to come to market with a faster card with more SMS enabled for the consumer market. What will probably happen down the line is a RTX 3080 Super or Ti variant with 20GB of VRAM with a few more SMs enabled to fit into that $900-$1000 price point that they left empty. The 3090 I’m almost certain will be the fastest consumer grade Ampere for this generation.

    That’s not to say they “can’t” release a “Titan” variant with more SMs enabled than what’s on the 3090 but it’s not going to be cheaper than the $1500 3090 and Titan class cards aren’t really aimed at mass consumer markets.

    Although NVidia apparently said there won't be a Ti version, I kind of doubt that. I can't imagine they'll leave everything as is until the next series - there's bound to be something coming out, maybe in response to AMD's offering later this year if they feel the need, or maybe around March-April 2021 (wild guess) for a 3080Ti / 3080 Super. There's a significant price gap between the 3080 and the 3090, and also a gap with specs, which leaves a perfect space for NVidia to release some kind of 3080Ti or 3080 Super with maybe ~16GB memory and a few tweaks and a bit higher clock to make it viable at around $1,200. That's my guess.
     
    From all accounts, the 3090 is the new Titan, and historically they usually only do one of those per series.. except with Pascal where they put out the Titan X Pascal, then a while later the Titan Xp, but I'm less inclined to think there will be a 3090Ti as opposed to a 3080Ti. Maybe they'll release something even more expensive than the 3090 but geared more towards compute rather than gaming, along the lines of the Quadro cards.
     
    I have the impression that NVidia looked at what AMD did to Intel with the huge price disparities, particularly with the high-count multi-core processors, and went, "hell no, we ain't going down that alleyway" and hence the much better prices we're seeing with the 30XX series, particularly in light of the substantial performance increase over the 20XX series.

    A super may be possible, a ti is not. The 3090 is basically the full gpu with nothing disabled. A 3080 ti is likely.

    Considering there's a 3090 Kingpin planned, I find it very unlikely there will be a higher end card.
