We've already looked at one HD 4890 to see how it goes against a number of single GPU cards on the market and since the Sapphire model is quite similar to the GIGABYTE model, with the only difference being the fact that Sapphire has chosen to utilize the stock clocks, we will do something a bit different in our comparisons.

What we'll do is see how the card competes solely against the HD 4870. Compared to our other review, this gives us a clearer picture of the kind of performance improvements we've seen over the last model from ATI.
