![]() The 8-Core Mac ProĪll of the original Mac Pros were quad-core machines, but in April 2007, Apple launched a new high-end model at $3,997. The Mac Pro could be configured in countless ways on Apple’s online store, of course, with faster (or slower) Xeons, more RAM and storage, a better card, AirPort and Bluetooth cards and a second SuperDrive. When the Mac Pro first went on sale, Apple offered a single SKU for $2,499: Like the G5, it came with 8 RAM slots and was upgraded to a total of four PCI Express slots as well. For those who wanted it, a second optical drive could be installed as well. A user just had to screw a hard drive to the carrier and slide it into place for the system to see it. The Mac Pro came with 4 hard drive carriers. The Xeons ran cooler, so Apple had more room for goodies. The G5 required a system of nine computer-controlled fans, and later models came complete with liquid cooling modules. This efficiency allowed Apple to drastically redesign the interior of the Mac Pro: The Mac Pro offered twice the performance of the Power Mac G5 while running much cooler, and without the need of the kilowatt power supply in the quad-core G5. Schiller praised the Xeons for being far more efficient than the G5. The new desktop used Intel’s “Woodcrest” Xeon chips, in speeds up to 3.0 GHz, a number that eluded Apple and IBM in the PowerPC days.
