Penryn Based Mac Pros Soon?

AppleInsider reports that Apple is ready to unleash Penryn-based Mac Pros as soon as Intel can provide the new chips to Apple.

They'll also be amongst the first machines from any PC manufacturer to employ chips from Intel's upcoming Penryn family of 45-nanometer (nm) microprocessors -- specifically the upcoming Hi-k Xeons, which will be available in dual- and quad-core variants for workstations with front-side bus speeds of either 1333MHz or 1600MHz.

This article corroborates an Inquirer report which claimed that Apple was buying up high end (3.2GHz) Penryn processors this year, leaving little supply for other PC manufacturers.

AppleInsider believes that the new Mac Pro will top with an 8-core model utilizing two of these new 3.2GHz "Harpertown" 45-nm quad-core Xeons which offer a faster 1600MHz bus and 12MB of L2 cache. The new processor could offer up to 45% speed increases over existing Mac Pro processors for bandwidth-intensive applications.

The fate of the remainder of the Mac Pro line remains less certain, but Apple appears to have the option of a number of dual-core Penryn ("Wolfdale") processors that could find their way into the lower-end Mac Pros.
