| The Bottom Line | 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. | AMD's new high-end dual-core CPU offers plenty of bang for the buck, outpacing Intel's Pentium 965 Extreme Edition, which costs $200 more. Sounds like a good deal, but wait to see what Intel's next-gen Core 2 Duo chips have to offer when they debut later this year. | AMD's Athlon 64 FX line has worn the desktop CPU performance crown for over a year. The king is dead. Intel's new flagship Core 2 Extreme X6800 not only hands AMD a defeat on all of our benchmarks, but it's also a more efficient, better designed chip overall. | 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. | Basic specs |
