AMD told us that they are putting a lot into that but also that they have some exciting technology up their sleeves with R700 to help out as well. When AMD began talking about no longer building high end hardware using single monolithic GPUs a few weeks back, we let them know that improving CrossFire support would be incredibly important going forward. Or should it? Building a Better CrossFire In other words, R700 should perform very much like a pair of 4870s in CrossFire. The clock speeds are identical to the Radeon HD 4870, and memory size per GPU has been doubled to 1GB, which could help in hi res cases with AA enabled. The R700 board is literally made up of two RV770s with a PCI Express switch connecting the two. Today's article is merely a preview as R700s won't be officially launched for at least another month, but AMD wanted to unveil a bit of what it's cooking. We're assuming that AMD will call the R700 based cards the Radeon HD 4870 X2, and based on the chart above we're expecting them to retail above $500 (possibly $549?).

Hot on the heels of the Radeon HD 4800 series launch, AMD shipped out ten R700 cards worldwide, attempting to capitalize on the success of the 4800 and showcase the strength of AMD's small-GPU strategy. Today however, is about the 250W, $500 multi-GPU solution - internally known as R700. The smaller $100 part has a name, and a release date, neither of which we can talk about at this point, but it's coming. The 150W TDP $300 part is the Radeon HD 4870, and the 110W $200 part is the Radeon HD 4850, the two cards that have caused NVIDIA quite a bit of pain already. The "Scalable design" block we already know about, that's RV770 - we reviewed it last month.
