Rumors surrounding NVIDIAās RTX 50 SUPER lineup have resurfaced after months of uncertainty. A recent listing from power supply manufacturer Seasonic suggests that the NVIDIA GeForce RTX 5080 SUPER is still in development, revealing several hardware specifications that point toward a meaningful refresh instead of a completely redesigned GPU.
Although NVIDIA has not officially announced the graphics card, the latest leak indicates the company may focus on improving memory capacity and bandwidth while allowing the GPU to operate at a higher power level.
Seasonic Listing Reveals a 415W Power Rating
The newest leak appeared through Seasonicās online PSU wattage calculator, where the GeForce RTX 5080 SUPER was listed alongside other upcoming RTX 50 SUPER models.
According to the listing, the graphics card carries a 415W Total Board Power (TBP). That is approximately 15% higher than the standard RTX 5080, which ships with a 360W rating.
The additional power budget is unlikely to come from a larger GPU core configuration. Instead, it is expected to support faster memory modules, higher operating frequencies, and improved overall stability under heavy workloads.
24GB of GDDR7 Could Be the Biggest Improvement
The biggest upgrade appears to be the graphics memory.
Current leaks suggest the NVIDIA GeForce RTX 5080 SUPER will feature 24GB of GDDR7 VRAM, replacing the 16GB configuration found on the existing RTX 5080. NVIDIA is reportedly using newer 3GB GDDR7 memory modules, allowing the company to increase capacity without changing the existing 256-bit memory interface.
Memory speeds are also rumored to increase from 30 Gbps to 32 Gbps, boosting bandwidth from 960 GB/s to approximately 1,024 GB/s, crossing the 1TB/s milestone.
For gamers, creators, and AI developers, the additional VRAM could provide a noticeable advantage in demanding workloads, especially at 4K resolution and during large AI model processing.
GizmoAlert Insight: While raw GPU horsepower often grabs the headlines, VRAM has become equally important. Modern games, AI applications, and creative software continue to demand more memory, making a 24GB upgrade one of the most practical improvements NVIDIA could offer.
GPU Performance May Stay Largely the Same
Interestingly, current information suggests NVIDIA may not significantly increase the CUDA core count.
The RTX 5080 SUPER is expected to continue using the Blackwell GB203 GPU, although reports indicate it could move to a newer GB203-450 variant instead of the existing GB203-400 used by the standard RTX 5080.
If accurate, the graphics card would retain:
- 10,752 CUDA Cores
- 256-bit memory bus
- Blackwell architecture
Performance gains would therefore come primarily from higher clock speeds, faster GDDR7 memory, increased bandwidth, and the larger VRAM capacity rather than additional processing cores.
RTX 5080 SUPER vs RTX 5080
Compared to the current RTX 5080, the SUPER model is expected to offer several improvements while maintaining the same underlying architecture.
| Specification | RTX 5080 | RTX 5080 SUPER (Rumored) |
|---|---|---|
| Memory | 16GB GDDR7 | 24GB GDDR7 |
| Memory Speed | 30 Gbps | 32 Gbps |
| Memory Bandwidth | 960 GB/s | 1,024 GB/s |
| CUDA Cores | 10,752 | 10,752 |
| Memory Bus | 256-bit | 256-bit |
| Total Board Power | 360W | 415W |
RTX 50 SUPER Lineup Appears Back on Track
Earlier reports suggested NVIDIA had delayedāor even cancelledāthe RTX 50 SUPER refresh because of ongoing GDDR7 supply constraints and the companyās strong focus on AI accelerators.
However, recent leaks from multiple industry sources now indicate development is progressing again. Besides the RTX 5080 SUPER, the Seasonic listing also references the RTX 5070 SUPER and RTX 5070 Ti SUPER, suggesting NVIDIA may still launch a broader SUPER lineup.
No board partners have officially acknowledged these products, but the appearance of the cards in manufacturer databases often signals that launch preparations are underway.
Launch Window Still Remains Uncertain
NVIDIA has yet to announce the GeForce RTX 5080 SUPER officially.
Industry insiders currently expect the RTX 50 SUPER family to launch sometime during the second half of 2026, although some reports suggest availability could slip into CES 2027.
Pricing also remains unknown. If NVIDIA positions the RTX 5080 SUPER between the RTX 5080 and RTX 5090, the upgraded memory alone could justify a higher launch price than the current RTX 5080.
Final Thoughts
The latest leak paints a clearer picture of NVIDIAās strategy for the RTX 5080 SUPER. Rather than redesigning the GPU, the company appears to be addressing one of the most common requests from enthusiasts: more VRAM.
A jump to 24GB of GDDR7 memory, faster bandwidth, and a 415W power limit could make the card especially attractive for gamers, AI developers, content creators, and professionals who frequently work with memory-intensive applications.
Until NVIDIA confirms the specifications, every detail should still be treated as unofficial. Even so, the growing number of leaks suggests the RTX 50 SUPER lineup may finally be moving closer to reality.
