Mac Pro Impressions and Developer's Note
Meanwhile, MacRumors users have started getting their Mac Pros. The shipping version of Mac OS X with the new Mac Pro is 10.4.7 (Build 8K1079). This Photoshop test was performed (under Rosetta) at 4min 8seconds on a Dual 2.66GHz Intel Mac Pro with 1GB RAM.
Those products are still referred to as being equipped with "AirPort Extreme" cards, although they differ from Apple's AirPort Extreme card for PowerPC systems. Like the Atheros cards, however, the Broadcom card in the Mac Pro connects to two antennas, suggesting Apple may be planning to support the 802.11a protocol in the near future.
