Intel leaks details of Mac Pro-bound Xeon chips
Intel Corp. plans to launch its Penryn-based quad-core Xeon family of microprocessors on November 11, which may provide Apple with an opportunity to boost the specs of its high-end workstations ahead of the holiday shopping season.
Each of the new processors will sport a Thermal Design Power (TDP) of 80 watts, pack 12MB of Level 2 cache, and run on a 1333MHz front-side bus. The only exception is the high-end 3.16GHz chip, which was listed with a TDP of 120 watts.
According to the information listed on Intel's reseller site, the new chips will fetch between $209 for the 2.0GHz model to $1,172 for the 3.16GHz variant. In the sweet spot of the Xeon lineup — where Apple has historically chosen its standard Mac Pro processors — lies a 2.83GHz model priced at $690.
Penryn, the next iteration of Intel's Core 2 micro-architecture, will signify a shift by the chipmaker to 45-nanometer fabrication process. Both desktop and mobile Penryn chips are also in the works, though Intel has not yet provided any indication of their precise release dates.
