A little preview action
Not too long ago the idea of a multi-GPU graphics card seemed taboo and brought about a lot of negative connotations with it. The GeForce 7950 GX2 was the first in the modern NVIDIA/ATI era and some board partners went in other multi-GPU directions until the Radeon HD 3870 X2 was released. We took the 3870 X2 as an answer to NVIDIA's high end cards because the company didn't have a single GPU that could compete with the competitions parts on its own; something of "we need answer" product.
Today's preview of the HD 4870 X2 card from AMD proves that this time AMD was planning ahead. Our review of the RV770-based Radeon HD 4850 and HD 4870 cards showed the new GPU architecture to be very potent indeed and NVIDIA is very scared of what the dual-GPU version, known as R700 previously, would do to its line of cards. Today we were allowed to post a short "preview" of the card's performance and I have to say you will likely be impressed.
AMD's Radeon HD 4870 X2 Card
The Radeon HD 4870 X2 card is AMD's answer to NVIDIA's flagship GTX 280 card in terms of pricing and placement. Even though NVIDIA recently dropped a bomb and lowered the price of the GTX 280 from $649 to $499, the estimated pricing we have seen for AMD's card is in the ">$500" range and will likely fall on the lower end of that open-ended range now. Isn't competition a wonderful thing?
In our email about this preview AMD asked for us to "keep this high level and not go deep on the architecture" since they were "leaving something for the full NDA" at a later date. Hmmm....okay how's this:
- Two GPUs
- One board
- Radeon HD 4870 cores
- PCIe 2.0 bridge chip
- GDDR5 memory
- HD 4870 clock speeds
- 1GB buffer to each GPU for 2GB total (this was updated from the original text that indicated 512MB per GPU)
- 1x8-pin PCIe and 1x6-pin PCIe power connectors
- Remember the HD 3870 X2 design? Yeah, pretty much like that.
That pretty much tells the picture, but we'll include some of these here as well.
