NVIDIA GeForce GTX 550 Ti Graphics Card (Palit and Zotac) Review
Power / Temps / Noise / Overclocking
As the 6900 series and GTX 500 series perform power management in a different way to older cards we have changed the way we test power and temperature levels in recent reviews. For idle power we list the full system use at the wall after sitting at the desktop with no activity for 5 minutes. Load power is the highest reading we saw for the full system when testing during this review. Temperatures are taken in the same way. Noise levels are taken after a period of prolonged gaming in a scenario which applied maximum load to the GPU.
Looking first to the comparison between our two 550s it is interesting to see that the Zotac card performs better at idle than the Palit model. That said the Palit reverses the situation when gaming, dropping the temperature by a few degress and the custom PCB lowering power use to 343w. That isn’t enough to compete with the Radeon system though which doesn’t rise above 289w.
Here are the scores for 3DMark 11’s performance mode with our maximum overclocks applied.
