It would be interesting to know the strategy behind ATI and their decision to release the HD 5400 series before the HD 5500. Considering the samples arrived only days apart, we doubt it was because one was ready and not the other. They could've almost released both cards at the same time; maybe they just wanted to spread it out a bit so they received more coverage instead of having one review / article on two models. Now they end up with two.

The big question that needs to be answered today is whether or not the HD 5570 performs closer to the HD 5670 or closer to the HD 5450. For the simple fact that we like performance, we hope that it leans towards the HD 5670, but we're really not sure. Before we find out just how it does perform, let's take a closer look at the package and the card itself.
