NVIDIA GTS 450 SLI – An Impressive Duet

Microsoft DirectX SDK

Setting : 1920×1080; Default; DirectX 11

We also noted an exponential performance improvement of over 90% in this DirectX 11-specific benchmark from Microsoft.

Setting : 1920×1080; DirectX 11, AF x16, No-AA

The two overclocked GTS 450s managed to stay above the 30 FPS mark across all settings in this benchmark.

Now this is the one case where SLI failed to give significant performance improvement. In our MPEG4, 720×480 video transcoding scenarios, there is zero difference between every tested configuration.

Power Consumption

Compared to a single GTX 470 OC, the two GTS 450s –overclocked or not- consume less power under full load condition. When idle, the GTX 470 OC gets ahead by a very small margin.
