NVIDIA GeForce RTX 3090 SUPER to be the first GeForce with 1TB/s memory bandwidth?
Just a day after Greymon55 broke the news about the upcoming RTX 3090 SUPER SKU, another respected leaker kopite7kimi shares more details on the supposed flagship SKU.
RTX 3090 SUPER: ~450W of power?
It seems that GeForce RTX 3090 SUPER power consumption is growing by the day. According to Greymon55, the TDP of RTX 3090 SUPER is expected at higher than 400W. Kopite appears to agree with this rumor, but he further adds that this SKU’s TGP is equal to or higher than 450W, a 100W more than RTX 3090. Do note this might simply be a typo and he actually means under 450W.
This amount of power will likely force AIBs to use three 8-pin power connectors by default (allowing 450+75W of power). Alternatively, a single Molex 12-pin power connector should be sufficient as it provides a maximum of 648W of power.

RTX 3090 SUPER: 1 TB/s memory bandwidth?
Furthermore, it is said that the RTX 3090 SUPER would be the first NVIDIA RTX 30 graphics card to feature 21 Gbps memory. Last year before NVIDIA even confirmed that RTX 30 series are coming, a memory manufacturer Micron confirmed that the then-upcoming RTX 3090 would offer memory speed between 19 to 21 Gbps. The graphics card eventually launched with 19.5 Gbps memory, leaving the remaining 1.5 Gbps as headroom for NVIDIA’s power optimizations. Increased power may mainly come from the faster memory clock.

There is no NVLink on RTX 3090 SUPER?
The RTX 3090 SUPER, considered to be the new flagship model, will no longer feature an NVLINK connector according to Kopite7kimi. This multi-GPU interface is now exclusive to the RTX 3090 non-SUPER and judging from Kopite’s statement, will likely remain so. Even the RTX 3080 Ti which launched 2 months ago lacks NVLink. The lack of NVLink on an RTX 3090 SUPER model might suggest that NVIDIA is abandoning this feature for the GeForce brand.
As noted by both leakers, the desktop GeForce RTX 30 SUPER series might launch in 2021. NVIDIA is also planning a mobile refresh featuring GA103 GPU, which Kopite7kimi had previously suggested. It is unclear if NVIDIA is also wishing to upgrade its existing RTX 3080 and 3070 models to SUPER variants, both have just recently been upgraded with Ti-specs offering higher performance.
