AMD has finally let loose its new flagship graphics card today; the dual-GPU 4870 X2. We've already learnt so much about it over the last few months in particular, with stacks of pre-release sightings and the odd benchmark here and there to reflect on its expected (and quite dazzling) performance.
From what's been seen of the card, it becomes the fastest on the market to date; beating out NVIDIA's GTX 280 in most cases. Today we get clarification of this with coverage surfacing all over the web. You can find it all via the below links :-

The HD 4870 X2 is really two HD 4870s on a single PCB. We have two sets of 800 stream processors, two sets of 40 texture units and 16 ROPs. Each 55nm core sports the same 956 million transistors we saw on the HD 4870 and two 256-bit memory buses.
Unlike the HD 3870 X2, the HD 4870 X2 clocks aren't down when compared to its single GPU counterpart. We see the same 750MHz core clock and 900MHz (3600MHz data rate) memory clock on the 2GB of HD 4870 X2.
