It is said that Intel's Smithfield dual-core CPUs are rated for a thermal design power of 130W, an increase of 13% from today's Prescott processors.
Dual-core and multicore chips promise to be one of the most important advances in processor development history. Intel and AMD claim to be able to achieve new performance levels by integrating two processor cores into one package. This apparently will be possible even with processor frequencies significantly below today's fastest processors. We were also told in the past that these speed gains will require less or little more power than an Athlon 64 or a Pentium 4 5xx/6xx.
It seems that Intel will not be able to achieve that goal.
