The never ending GPU wars between Advanced Micro Devices (AMD) and Nvidia means there's always something newer, better, and faster right around the corner. Neither player likes to tip their hand ahead of schedule, but the Internet is the ultimate tattletale, and right now it's telling us what to expect from AMD's upcoming Radeon HD 8870 and 8850 parts. If the source is to believed, that is.
According to V ideocardz.com's source , which is the same one that leaked Tahiti specs a few months before launch, AMD's Radeon HD 8870 will be as fast as Nvidia's GeForce GTX 680. Based on AMD's Oland XT GPU, the 8870 boasts 3.4 billion transistors (up from 2.8 billion found in the 7870), a 1050MHz base clockspeed, 1100MHz boost clockspeed, and 25 percent better memory bandwidth (192GB/s) compared to the 7870. The card will carry an MSRP of $279.
AMD's Radeon HD 8850 is based on Oland Pro and has the same number of transistors and memory bandwidth as the 8870, but slower clockspeeds (925MHz base and 975MHz boost). It will sell for $199 (MSRP). It will be comparable to Nvidia's GeForce GTX 670 part.
Regarding a launch date, early info points to around January 2013.
