| The Bottom Line | AMD's new Phenom quad-core CPU has little to recommend it over competing chips from Intel. The Phenom is marginally less expensive, but not enough to make up for its subpar performance. Unless AMD drops prices more aggressively, it looks like Intel will maintain its grasp on the CPU market for the foreseeable future. | AMD's new Phenom X4 9850 is overpriced and outclassed compared with its Intel-based quad-core competition. If PC vendors can use this chip to make cheap systems (as they did with older Phenoms), we might have nicer things to say, but as a DIY part at this price, we can't recommend AMD's latest quad-core CPU. | Thanks to an expensive new motherboard requirement, Intel's new Core i7 desktop processors will remain enthusiast and professional-level parts until more affordable complementary hardware comes out later next year. Speed never comes cheap, however, and if you're willing to spend for it now, you'll find yourself in possession of the fastest CPU on the market. | AMD's new Phenom quad-core CPU has little to recommend it over competing chips from Intel.
