The availability of Intel's latest Xeon E5 workstation-class chips next week was reported by British site The Inquirer.
The new Xeon E5 chips incorporate the Sandy Bridge micro architecture that first appeared in MacBook Pros and iMacs early last year, followed by a mobile variant used by Apple in the MacBook Air last summer.
Apple's latest Mac Pro models currently use Intel Xeon Bloomfield or Gulftown processors based on the Nehalem and closely related Westmere microarchitectures.
The latest release of OS X 10.7.3 Lion included support for AMD's high end Tahiti graphic cards, which are expected to arrive in the market around the same time as Intel's new Xeon chips.
However, people famliar with the matter have said that Apple's management, as far back as last May, were in limbo over whether to put any additional resources toward the Mac Pro product line.
Internal discussions at Apple were said to focus on the fact that sales of the high-end Mac Pro workstations have dropped off so considerably that the desktop machines are no longer particularly profitable for the company.
