Early DLSS 5 Testing Suggests the RTX 5090's Single Power Connector Might Be the Bottleneck

Summary by techpowerup.com
Community testing of leaked DLSS 5 builds suggests the tech may already be hitting a wall on NVIDIA's own flagship GPU. Tom's Hardware ran the neural rendering model through Cyberpunk 2077, Hogwarts Legacy, and Control on an RTX 5090 Founders Edition, as well as an MSI RTX 5090 Lightning Z. Surprisingly, the results point to power delivery as the potential bottleneck rather than compute horsepower. The test used a community Optiscaler injection …

The first independent tests of NVIDIA DLSS 5 leave as surprising as they are worrying results, especially from the point of view of the consumption of the graphics. Their execution causes a significant loss of performance, but also triggers the consumption of the graphics card to the point that the energy limit of the RTX 5090 Founders Edition could be preventing this technology from deploying its full potential. The tests carried out by Tom’s H…
