Gutterne hos TweakTown har tidligere testet Sapphire Radeon HD 7870 XT grafikkortet med Boost. Her går de mere grundigt til værks for at se hvor meget grafikkortet kan overclockes.
The card itself was excellent in so many ways and it was rounded off with a really strong price. The big issue comes from the marketing side of things. As we mentioned in that review the new Tahiti LE based HD 7870 isn't a model that AMD are promoting. Instead only certain companies are offering the model with PowerColor being one, and another being Sapphire.
Due to this it's up to companies themselves to promote it and while they'll do a pretty good job, there's no denying that the product won't get the same attention verse a model that every AMD partner was promoting. Since we've already looked at one of the new Tahiti LE based HD 7870's at its out of the box speeds, we'll today be taking time to overclock a Sapphire model to see just what it's capable of doing.
As always there are a few things we need to do before we get into the overclocking side of things. We'll start with the package to see what Sapphire is offering before we move onto the video card itself. Once we've done that we'll take a look at the specifications of the card out of the box before we look at how we went with the overclocking. Finally we'll quickly check out our testbed and then get into the performance side of things.
