Hardmac is reporting that Apple will release new Mac Pro models in early 2010, the site also pinpoints Intels yet to be released Xeon Gulftown CPU for the next generation of top-end Mac Pro models.
The future Intel CPU features 6 cores and is manufactured using the new 32nm process. PCLab had run benchmarks on the CPU but swiftly removed them due to an Intel NDA (nondisclosure agreement) their report suggests that Gulftown is "50% faster than the corresponding quad core Xeon for parallel tasks. Despite having 50% more transistors, the CPU strongly benefits from 32-nm engraving as it drains 50% less power in idle mode and 10% less in full loading mode."
