The Futuremark 3Dmark Vantage results are a little surprising as they show the new Radeon HD 4870 X2 being outperformed by a Crossfire setup running two individual Radeon HD 4870 cards.

While we expected both configurations to deliver similar performance, we had thought that the single card with two GPUs would have had the slight edge. Nevertheless, the Radeon HD 4870 X2 was still the second fastest setup tested, and remained the fastest single graphics card.
