MojoKid writes "When AMD announced the high-end Radeon HD 7970, a lower cost Radeon HD 7950 based on the same GPU was planned to arrive a few weeks later. The GPU, which is based on AMD's new architecture dubbed Graphics Core Next, is manufactured using TSMC's 28nm process and features a whopping 4.31 billion transistors. In its full configuration, found on the Radeon HD 7970, the Tahiti GPU sports 2,048 stream processors with 128 texture units and 32 ROPs. On the Radeon HD 7950, however, a few segments of the GPU have been disabled, resulting in a total of 1,792 active stream processors, with 112 texture units and 32 ROPs. The Radeon HD 7950 is also clocked somewhat lower at 800MHz, although AMD has claimed the cards are highly overclockable. Performance-wise, though the card isn't AMD's fastest, pricing is more palatable and the new card actually beats NVIDIA's high-end GeForce GTX 580 by just a hair."
