Power and Temperature
Power
The listed TBP for the GIGABYTE GeForce RTX 5080 WINDFORCE SFF 16G is 360Watts. By default, the card runs under by 4%. When overclocked, the card is just over the limit, but of course, we chose a very conservative approach. The card uses 10% more power at default versus the XFX Swift Radeon RX 9070 XT White Edition.
Temperature
If you happened to read our review of the XFX Swift Radeon RX 9070 XT White Edition, you know that card has an outstanding heatsink design. This is once again demonstrated here. The delta between the two cards is over 10C. The temperatures between default and overclocked are nearly identical. With that in mind, we are dealing with a video card that has been compacted into the NVIDIA SFF size limits. No matter how the heatsink performed, we kept the fans at their default, and they were essentially silent. Overclocked the fans barely exceeded 50% fan cycle. The memory temperatures were a different story. Here the GIGABYTE GeForce RTX 5080 WINDFORCE SFF 16G was over 10C cooler. Overall, GIGABYTE has a well-designed heatsink for this smaller-sized RTX 5080, and it’s very quiet to boot.
