| Bottom line | 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. | 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. | We recommend the AMD A8-3850 to mainstream desktop PC users in search of capable gaming power and multithreaded application performance. | Info unavailable | Intel's Core 2 Duo E6700 offers the best price-to-performance ratio we've seen in a desktop chip. For half the cost of AMD's top-of-the-line chip, you get identical if not superior performance and better power efficiency. AMD surprised us last year with its completely dominant dual-core chips, but Intel regains the crown with Core 2 Duo. |
