Size, Noise and HeatThe compact GeForce GTX 550 Ti reference card isn't very noisy, whether at idle or hard at work running 3D games.
Power ConsumptionIn any case, power consumption is more or less equivalent to the next model up, the GeForce GTX 560 Ti, drawing 90 watts at idle and 330 watts in 3D load. This is a bit disappointing, especially as the Radeon HD 6850 does a good deal better in load, drawing just 293 watts.
Note: these values are for the test computer as a whole and not the graphics card alone.
Gaming PerformanceThe GTX 550 disappointed us in video games, where the level of performance doesn't stand up to that of its direct competitor, the Radeon HD 6850 (9% advantage to the Radeon). On a high (1920 x 1200 pixels) or medium (1680 x 1050 pixels) definition screen, things are pretty much the same, with an average performance lower than the older generation GeForce GTX 460.

This is especially problematic as at this level of performance as the standard arguments in favour of NVIDIA cards no longer stand up. Activating options such as 3D Vision and PhysX on this model will require you to lower the graphics detail pretty drastically.
NVIDIA has failed to impress us with this model, which is too far behind the excellent GeForce GTX 560 Ti. We really don't see what this model can offer compared with the AMD Radeon HD 6850. NVIDIA will have to price the card very aggressively if it's to attract many customers.
