In the shadow of global political power shifts, there are also new signs of a change of course in the GPU cellar – this time in the form of a refresh. According to new leaks, the NVIDIA GeForce RTX 5080 SUPER will probably not just be a cosmetic update, but a consistent response to the bandwidth and capacity criticisms of the original. As usual, the preliminary information comes from Twitter leaker “Kopite7kimi”, whose hit rate in the past has not necessarily left much to be desired.
GB203-450 with 24 GB GDDR7 at 32 Gbps
The GB203 chip is once again at the heart of the refresh – this time in the GB203-450 variant, which distinguishes it from the previous GB203-400 (RTX 5080 Non-SUPER). The number of active shaders remains the same: 10,752 CUDA cores are still on board. The real change is in the memory configuration. This is based on 24 GB GDDR7, which is clocked at 32 Gbps. This means that the memory is 6.6% higher than the bandwidth of the original RTX 5080 model with 30 Gbps and 16 GB capacity. The memory connection is still made via a 256-bit interface, resulting in a total bandwidth of exactly 1,024 GB/s – a round terabyte mark that may sound pretty in marketing terms, but hardly makes the world go round in everyday life. Nevertheless, compared to the non-SUPER version with 960 GB/s, this is a decent increase, even if it hardly means more than 5% more performance in games.
TBP increases to over 400 watts
There is also an update in terms of power consumption – whether you like it or not. The Total Board Power (TBP) has risen to “400W”, which is likely to be somewhere between 400 and 420 watts. For comparison: the regular RTX 5080 was 360 watts, which means that it now draws around 11% more from the socket. Higher clock rates and the faster and larger memory will probably account for the lion’s share of this increase in consumption. It remains to be seen whether this will result in an additional load on the cooling system in practice or whether NVIDIA will simply release more clock reserves. PCB and model numbers
According to the leak, the card is based on the PCB with the designation PG147-SKU35, which indicates that the layout has changed slightly compared to the non-SUPER version. Whether this has an impact on cooling, power supply or the PCB layout remains to be seen – but it could mean that the board partners will have to respond with new cooling solutions.
Classification in the lineup and outlook
Interestingly, the RTX 5080 SUPER leak remains a lonely signal so far – on the Computex show floor, the board partners remained silent on possible refreshes, which indicates a launch in the fourth quarter of 2025 at the earliest. A launch at CES 2026 would be conceivable, where NVIDIA traditionally places major consumer updates. The SUPER series would then be a reaction to AMD’s next RDNA generation and Intel’s planned Battlemage cards – a kind of interim solution to fill the gap until the RTX 60 generation. However, the fact that the focus is on memory expansion rather than technical innovations suggests that we should not expect any groundbreaking architectural leaps before 2026.
Technical overview – RTX 5080 SUPER vs. non-SUPER
| Feature | RTX 5080 SUPER | RTX 5080 Non-SUPER |
|---|---|---|
| GPU | GB203-450 | GB203-400 |
| CUDA cores | 10.752 | 10.752 |
| VRAM | 24 GB GDDR7 | 16 GB GDDR7 |
| Memory interface | 256-bit | 256-bit |
| Memory clock | 32 Gbps | 30 Gbps |
| Memory bandwidth | 1.024 GB/s | 960 GB/s |
| TBP | 400W | 360W |
More memory, more power, few surprises
As expected, the GeForce RTX 5080 SUPER is not a revolutionary product. It is a typical refresh in the style of previous SUPER variants: A little more VRAM, a little more clock speed, higher bandwidth – all within the bounds of what is expected. For users with memory-hungry workloads, the 24 GB configuration may be an interesting upgrade. In terms of efficiency and gaming performance, however, a marginal increase is to be expected. Once again we see that NVIDIA prefers to make conservative adjustments to details rather than surprise with disruptive innovations.
