Following the premature arrival of AMD's upcoming quad-core Phenom processors on a small e-tailer's website, AMD's upcoming Radeon HD 3800-series graphics cards have popped up on Buy.com. The two cards are the Radeon HD 3850 and the Radeon HD 3870, and Buy.com lists them for $217.99 and $268.99, respectively, with free shipping. Neither card is in stock, and Buy.com displays neither detailed specifications nor pictures of the two cards. Still, the online retailer confirms that the Radeon HD 3850 is outfitted with 256MB of GDDR3 RAM and that the 3870 has 512MB of GDDR4 RAM.
For detailed specifications, you'll do no better than Spanish-language site MadBox PC, which seems to have posted the contents of AMD's Radeon HD 3800 PowerPoint presentation. The presentation says the Radeon HD 3850 will have a 670MHz clock speed and an 830MHz memory clock, while the Radeon HD 3870 will run at 775MHz or faster with memory at 1.125GHz (that's an "effective" 2.25GHz). Both cards will have 320 stream processors, a 256-bit memory interface, and PCI Express 2.0 support. Pictures of the two models suggest the 3870 will have a dual-slot cooler and the 3850 will have a single-slot cooler.
