Submission + - AMD Steamroller architecture to improve per-core performance (

Dr. Damage writes: "AMD's next-gen Bulldozer architecture hasn't performed up to expectations--it's relatively power-hungry and has weak performance, especially in desktop-style applications that require strong single-thread performance. Fortunately, AMD revealed today at Hot Chips that it is working to improve single-thread performance and energy efficiency with Steamroller, an upcoming architectural refresh."

Submission + - Dual-GPU monsters face off, raise questions (

Dr. Damage writes: Nvidia's new GeForce GTX 590 poses an interesting question to the subset of folks who buy $700 dual-GPU graphics cards: does performance rank above all else, or do considerations like board size and noise levels matter more? This latest high-end GeForce isn't quite as fast as AMD's similarly outrageous Radeon HD 6990, but it's smaller and substantially quieter.

Submission + - Radeon HD 5830 compared... to GeForce 7900 (

What if you're upgrading from a graphics card in that same price range that's two, three, or four years old? How much of an improvement can you expect? And is the new Radeon a good value for the money? This review compares it, and a host of today's other graphics cards, to products dating back up to four years ago, including a couple of GeForce 7900s.
