We've got a lot to discuss on this episode of the TR Podcast, starting with two listener mail questions. KJ wants to know how AMD's Zacate will stack up against Intel's Consumer Ultra-Low-Voltage offerings, while Chris asks if Geoff ever found a better MP3 player for swimming. Shortly thereafter, Scott reviews the newly rebooted Medal of Honor before getting into the meat of this episode: AMD's new Radeon HD 6850 and 6870 graphics cards. Scott gives us the skinny about the new Barts silicon, morphological AA, how these cards stack up against the Nvidia competition, and more. As we reach the tail end of this episode, Geoff brings up AMD's latest efforts in the domain of fan-speed controls, Cyril discusses Asus' dual-core, Ion-based Eee PC, and our editors all voice their thoughts on Apple's new—and expensive—MacBook Air models
