RV770 Debut - Radeon HD4850 CrossfireX Scaling
The RV770 supersedes its predecessor, the RV670, and is designed to give NVIDIA a tough time in the midrange consumer graphics arena. Will this new offering breathe new life into ATi's range? We'll walk you through with our cards from Powercolor, Asus and Sapphire.
The usual bla-bla about every new graphics accelerator released does get boring for readers and writers alike. To keep things simple, the HD4850 will pack all the features of the HD3850 and offer better number crunching. Priced to beat the NVIDIA 9800GTX in speed and value, the official threat from the Green Camp would be the price-slashed GeForce 9800GTX. On to the pictures!
For a current generation midrange offering, there is nothing in the presentation of the HD4850 to suggest otherwise. It shares a lot of similarities with the earlier brethren, the HD3850, with regards to PCB layout and thermals.
ATi allows multi-GPU configuration on the HD4850 too. We'd explore this option in this article after you're done reading my blabber.
The real differences, of course, lies under the hood. Here, you see the RV770 silicon sitting on its throne of solder balls flanked by Qimonda's 1.0ns 256bit memory.
