Several reviews are in for Advanced Micro Devices' latest microprocessors, and while the new chips don't bridge the gap between AMD and Intel's latest chips, they do run cooler than the company's previous offerings.
AMD's 65-nanometer chips, which started to trickle out of its factories earlier this month, are basically just a smaller version of its dual-core 90-nanometer chips. AMD did not introduce any major new features to improve performance along with its 65-nanometer chips, but the new manufacturing technology does allow it to build chips that use less power and are smaller. Smaller chips mean that AMD can yield more working chips from the silicon wafers produced by its chipmaking equipment, helping to reduce the incremental cost of building a chip.
The new chips are rated for a thermal design power of 65 watts of power, according to a review by the Tech Report. That's the same number attached to Intel's Core 2 Duo chips, although the companies measure power consumption in slightly different ways. In a basic sense, it's the number that system builders should take into account for the processor when designing the cooling systems for their PCs.
