The RV670 XT is the faster of the two RV670 chips that will arrive next month. Exactly what the names will be in stores remains to be seen. Right now we have at least three candidates; Radeon HD 3800, HD 2950, and somewhere along HD 2600XTX and HD 2650 appeared. Whatever the RV670 XT will be called, a user over att Chiphell has posted a picture of a card using this chip. The small text on the side says something like “XXXXX670XXX” and the card has a new Ruby sticker on the top.
Over at VR-Zone, a user has posted information about the new HD 3800 series. Consider it with a pinch of salt.
