After the rumors, the leaked specs, and the leaked photos, we've now come across purported 3DMark results for AMD's upcoming Radeon HD 6800-series graphics cards. The numbers track pretty well with what I was able to infer from that comparative slide that found its way online last month.
According to Xfastest, the Radeon HD 6870 scored P16270 in 3DMark Vantage, while the slower 6850 managed to hit P14872. Those numbers are slightly below those of the existing Radeon HD 5870 and 5850, respectively, the site says. Xfastest also posted some 3DMark06 scores, which show the two newcomers pretty much matching their previous-gen siblings.
According to recent evidence, these Radeon HD 6800-series cards will feature Barts Pro and XT graphics processors, but those won't be the highest-end GPUs in the Northern Islands family. Rumor has it that AMD is also cooking up a Radeon HD 6970 with a more powerful Cayman XT graphics chip inside. (Thanks to Expreview for the link.)
