AMD recently unveiled its Redwood graphics processor as part of the new Mobility Radeon HD 5000 lineup for notebooks. Soon, according to Fudzilla, Redwood will make an appearance on the desktop, too. The site has word that AMD will introduce a Redwood-based Radeon HD 5670 graphics card on Thursday, January 14.
The 5670, Fudzilla says, will have 400 stream processors, a 128-bit memory interface, either 512MB or 1GB of GDDR5 memory, and DirectX 11 compatibility. While the site also talks of 20 texture units, that figure seems unlikely—the Juniper chip that powers Radeon HD 5700-series graphics cards only has 10 texture units for its 800 stream processors.
In any case, some European e-tailers have already jumped the gun on Radeon HD 5670 listings. Price search engine Geizhals.eu lists cards starting at around €80, which strongly hints to sub-$100 pricing in the United States. (€80 technically works out to $116, but European prices tend to be higher than across the pond.) Geizhals also quotes some specs of its own: a 775MHz core clock speed, a 1,000MHz memory speed, and a dual-slot cooler. We'd advise taking that information with a grain of salt, naturally.
AMD told us about Redwood last year when it unleashed the Radeon HD 5870. At the time, the plan was to introduce two GPUs in the first quarter of this year: Redwood for the mainstream market and Cedar to serve the value market.
