NVIDIA GeForce RTX 5080 SUPER May Push Power to 415W With 24GB GDDR7 Memory
NVIDIA’s rumored GeForce RTX 5080 SUPER is starting to look like a much more memory-focused upgrade over the standard RTX 5080. According to a new entry spotted in a power supply wattage calculator, the upcoming Blackwell-based graphics card could carry a 415W TDP, making it noticeably more power-hungry than the non-SUPER model.
If accurate, that would place the RTX 5080 SUPER around 15% higher in power draw than the GeForce RTX 5080, which is rated at 360W. The increase appears to be tied less to a dramatic change in core count and more to a stronger memory configuration, higher memory speeds, and possibly improved clock speeds.
The biggest expected upgrade is VRAM. The GeForce RTX 5080 SUPER is rumored to feature 24GB of GDDR7 memory, compared to 16GB on the current RTX 5080. That is a 50% increase in memory capacity, which could make the card far more attractive for high-resolution gaming, creator workloads, AI-assisted applications, heavy texture packs, and future titles that demand more video memory.
The card is still expected to use a 256-bit memory bus, but the memory speed may rise from 30Gbps on the RTX 5080 to 32Gbps on the RTX 5080 SUPER. That would push total bandwidth to 1024GB/s, crossing the 1TB/s mark. For gamers and professionals, higher bandwidth can help improve performance in scenarios where large amounts of data need to move quickly between the GPU and memory.
The rumored GeForce RTX 5080 SUPER is said to use a Blackwell GB203 variant, possibly labeled GB203-450, while the standard RTX 5080 uses GB203-400. Both cards are expected to feature 10,752 CUDA cores, so the performance difference may come from memory improvements, firmware tuning, clock speed adjustments, and power limits rather than a major GPU core expansion.
In simple terms, the RTX 5080 SUPER may not be a completely new class of card, but it could be a more capable version of the RTX 5080 for users who need additional VRAM and bandwidth.
Expected RTX 5080 SUPER specifications include:
Graphics card: NVIDIA GeForce RTX 5080 SUPER
GPU architecture: Blackwell
GPU variant: GB203-450
CUDA cores: 10,752
Memory capacity: 24GB GDDR7
Memory bus: 256-bit
Memory speed: 32Gbps
Memory bandwidth: 1024GB/s
Power rating: Around 415W
Power connector: 16-pin 12V-2×6
Launch window: Not confirmed
Compared to the standard RTX 5080, the SUPER model is expected to offer the same number of cores but with a stronger memory setup. The RTX 5080 currently offers 16GB of GDDR7 memory running at 30Gbps, delivering 960GB/s of bandwidth. The rumored RTX 5080 SUPER would raise memory capacity to 24GB and bandwidth to 1024GB/s.
That extra memory could be one of the most important changes. Many modern games are becoming more demanding at 4K resolution, especially with ray tracing, path tracing, high-resolution texture packs, and frame generation features enabled. While 16GB remains strong for gaming today, 24GB would give the RTX 5080 SUPER more room for future titles and professional workloads.
The higher 415W rating also suggests that NVIDIA may be pushing the card harder to maintain performance gains. A 55W increase over the RTX 5080 is not small, and users interested in the RTX 5080 SUPER may need to make sure their power supply, case airflow, and cooling setup are ready for a high-end GPU with this kind of power demand.
For comparison, the rumored RTX 5070 Ti SUPER and RTX 5070 SUPER are also expected to bring memory upgrades, though their listed power figures appear unchanged for now. The RTX 5070 Ti SUPER is expected to sit around 350W, while the RTX 5070 SUPER may be around 275W. The RTX 5080 SUPER, however, looks like the model receiving the most noticeable jump in power.
Preliminary RTX 50 SUPER lineup details suggest the following:
The GeForce RTX 5080 SUPER may feature 24GB GDDR7 memory, a 256-bit bus, 32Gbps memory speed, 1024GB/s bandwidth, and a power rating above 400W.
The GeForce RTX 5070 Ti SUPER may feature 24GB GDDR7 memory, a 256-bit bus, 28Gbps memory speed, 896GB/s bandwidth, and a 350W power rating.
The GeForce RTX 5070 SUPER may feature 18GB GDDR7 memory, a 192-bit bus, 28Gbps memory speed, 672GB/s bandwidth, and a 275W power rating.
NVIDIA has not officially announced the RTX 50 SUPER series yet, so all specifications should be treated as preliminary. Board partners have also not publicly detailed custom models, pricing, or release schedules. That means the final specs, power targets, and launch timing could still change before the cards arrive.
As for availability, current rumors point to updates possibly coming in the second half of the year, with an actual launch potentially happening later, possibly around late 2026 or at CES 2027. Until NVIDIA confirms the lineup, the RTX 5080 SUPER remains an unreleased product, but the new power listing suggests the card may still be in development rather than cancelled.
If the rumored specifications prove accurate, the GeForce RTX 5080 SUPER could become one of the most interesting high-end GPUs in the Blackwell generation. A 24GB GDDR7 memory configuration, 1TB/s bandwidth, and higher power limit would position it as a stronger option for 4K gaming, content creation, and demanding GPU workloads.
The trade-off is clear: more memory and bandwidth, but also more power consumption. For enthusiasts chasing higher performance and better future-proofing, that may be a worthwhile exchange.
