NVIDIA Readying GeForce RTX 3090 SUPER, A Fully Unlocked GA102 with 400W Power?
NVIDIA is readying the GeForce RTX 3090 SUPER, the first "SUPER" series model from the RTX 30-series, following a recent round of "Ti" refreshes for its product stack. According to kopite7kimi and Greymon55, who each have a high strike-rate with NVIDIA rumors, the RTX 3090 SUPER could finally max-out the 8 nm "GA102" silicon on which nearly all high-end models from this NVIDIA GeForce generation are based. A fully unlocked GA102 comes with 10,752 CUDA cores, 336 Tensor cores, 84 RT cores, 336 TMUs, and 112 ROPs. The RTX 3090 stops short of maxing this out, with its 10,496 CUDA cores.
NVIDIA's strategy with the alleged RTX 3090 SUPER will be to not only max out the GA102 silicon, with its 10,752 CUDA cores, but also equip it with the fastest possible GDDR6X memory variant, which ticks at 21 Gbps data-rate, compared to 19.5 Gbps on the RTX 3090, and 19 Gbps on the RTX 3080 and RTX 3080 Ti. At this speed, across the chip's 384-bit wide memory bus, the RTX 3090 SUPER will enjoy 1 TB/s of memory bandwidth. Besides more CUDA cores, it's possible that the GPU Boost frequency could be increased. All this comes at a cost, though, with Greymon55 predicting a total graphics power (TGP) of at least 400 W, compared to 350 W of the RTX 3090. A product launch is expected within 2021.

Probably won't matter cooling wise these things already can't handle cooling the back memory chips.
We already know that the 3070 is around the sweet spot with the best performance per watt. Did anybody expect a top tier halo product to be affordable scalpers or no scalpers? No they did not. Do you complain that a Lamborghini is too expensive too?
This card is cool. I will enjoy looking at the benchmarks like I enjoy seeing an F1 race. I will never be able to afford one of these nor do I care, that isn't the point. This card is a powerhouse and is exciting from an enthusiasts perspective.
If I can get this t my nearby Microcenter, I'll consider upgrading LOL
Maybe they'll put a sticker or logo of a cross between Jensen Huang & Lerm on it from Squidbillies saying, "Death to Power Supplies!" or "Death to Case Cooling!". Does your money really want to go that way?
The memory stays the same at 24GB so I see no reason to upgrade if you have 3090 already.
all you have to do is pay the $100MM for the power unit & they promise to throw in a GPU (or 12) for free..... hehehehehehe :roll:
No. You're not insane.
Perhaps. You just woke up in hell.
Best,

Nvidia: put it in - everything works.
AMD may have nice hardware, but it's software is not competitive. This enables Nvidia to get away with its pricing and lies (Titan will be the fastest card, 3090 will not be replaced by a 3090s).
Perhaps Intel will be able to break things up in this market.
Its unlikely but still a very real possibility if those two giants don't start taking more proactive steps to keep their products more reasonably priced by their merchants/distributors. In the short term it doesn't affect them because they already sold the cards before they ever get into our hands; but in the long term, if more disgruntled customers start finding other alternatives, AMD & NVidia might as well hand over the gaming market to Intel on a silver platter.Yeah, you would think they would lay off the production of superfluous nonsense and focus on producing more of a few select lower-mid-higher tier cards. Where NVidia sees variety/diversity in their card lineups, I just see stupidity.
400W of reference board power? I think they stuck to 350 on the 3090 for a reason... (heat, if anyone's wondering), and there's the other thing. This SKU would undoubtedly be LHR, too, which means the miners would simply coop up all of the remaining vanilla 3090 stock, making its price balloon even higher and this card, relegated to a strictly gaming processor, unable to satisfy the demands of the extreme enthusiasts who still want to play around with multi-GPU rendering (as it lacks the NVLink port) and devoid of any workstation features or particularly endowed niche compute capabilities (i.e. FP64) - would then remain utterly overpriced in a niche so isolated, that it'd make the Titan V and the Titan RTX look like they were intended for the common guy.
Besides, let's take an objective look at the rest of the stack. Where are they going to add SUPER variants of other cards? They won't. The GA104 is already maxed out in the 3070 Ti, the 3080 is an amazing SKU for them to dump highly defective GA102 dies (given it has only 68 out of 84 units enabled), the 3070 already satisfies its segment and the 3060 Ti is already within 15% of it fulfilling the slot right below... the highest SM count difference remaining is between 3080 (68) and the 3080 Ti (80), a 3080 Super could be released with say, 72 or 74 SM, but that would have to be priced lower than the Ti, would basically cannibalize two SKUs, have zero market sense...
I'm prepared to call the Ampere stack finished, myself.
