NVIDIA Reportedly Working on GeForce RTX 3080 Ti Graphics Card with 20 GB GDDR6X VRAM
A leak from renowned (and usually on-point) leaker Kopite7kimi claims that NVIDIA has finally settled on new graphics cards to combat AMD's RX 6800 threat after all. After the company has been reported (and never confirmed) to be working on double-memory configurations for their RTX 3070 and RTX 3080 graphics cards (with 16 GB GDDR6 and 20 GB GDDR6X, respectively), the company is now reported to have settled for a 20 GB RTX 3080 Ti to face a (apparently; pending independent reviews) resurgent AMD.
The RTX 3080 Ti specs paint a card with the same CUDA core count as the RTX 3090, with 10496 FP32 cores over the same 320-bit memory bus as the RTX 3080. Kopite includes board and SKU numbers (PG133 SKU 15) along a new GPU codename: GA102-250. The performance differentiator against the RTX 3090 stands to be the memory amount, bus, and eventually core clockspeed; memory speed and board TGP are reported to mirror those of the RTX 3080, so some reduced clocks compared to that graphics card are expected. That amount of CUDA cores means NVIDIA is essentially divvying-up the same GA-102 die between its RTX 3090 (good luck finding one in stock) and the reported RTX 3080 Ti (so good luck finding one of those in stock as well, should the time come). It is unclear how pricing would work out for this SKU, but pricing comparable to that of the RX 6900 XT is the more sensible speculation. Take this report with the usual amount of NaCl.

Personally, I think the real problem is Samsung's 8 nm node not being able to produce a reasonable number of GPUs for nvidia and board partners. Random fact: there is not a single fully unlocked GPU die either in the current, or rumoured 30-series product stack anywhere. Why is that? Is nvidia making room for a later coming Super series? Maybe, but I think yields are so low that they basically can't produce fully functional dies at all, and even partially functional ones are short on supply - that's probably why we're hearing rumours about the large GA102 seeping down into 3070 Ti territory and the GA104 into 3060 Ti, or even 3060 levels (instead of introducing new, smaller dies as usual).
In short: scalping is only ever an issue when there is a pre-existent shortage of a certain product.
If it really was Samsung's node, and the yields would be low due to defects for the 3090 and 3080, You could salvage those to get decent number of 3070 GPUs and these have problems with stock as well. Problem is elsewhere.
Why 320bit mem bus? If people are going to pay +$300 they would want some upgrade to the mem bus like 352bit.
What ever! If I feel like Nvidia is screwing me I will jump to AMD
The other thing is, maybe NV was rushing the release so bad, they didnt have the stock to begin with. Maybe these cards were going to be released later not August but much later. They didnt have the stock but wanted to release it before AMD. Hard to tell but the node problem or yields problem (they are there due to large chips) is not convincing me.
Rumored 536mm² is only 15% smaller than Nvidia's 628mm². TSMC N7 is a smaller, newer and more complex node compared to Samsung's 8N.
It costs exactly the same to make a 3090 GPU die as it does a 3080 GPU die - they are the SAME THING - only difference is the 3080 has a few broken CUs in GPU die so they disabled them and sell it for less.
If they are able to make and sell 3080 for 800 PROFITABLY then they DEFINITELY could make the 3090 and sell it profitably for 800 too. Its just they don't have to - there are enough idiots around who will gladly give them another 700 in profit for the same thing.
There is also a marketing or PR angle to this. The people who have bought RTX3090 would be disappointed or angry if the same card was sold for 30% less so soon after release. So a new SKU is slightly worse than RTX3090 and current RTX3090 owners can use that small bit to make them feel better.
