No one should be surprised, but if you were looking for a speed freak of a laptop, you're going to want to glaze those lustful eyes over the
MacBook Air. While the new hotness has a speedy memory bus, overall its performance is dramatically smushed by its integrated graphics, anemic 1.6GHz Core 2 Duo processor, and 1.8-inch hard drive. Yes, you can officially call the MacBook Air the slowest machine Apple makes -- but you already figured as much, right? No one buys an ultraportable for its real ultimate power.
- All machines tested with Xbench 1.3. Sorry, we didn't have a Mac Pro around.
- All machines tested were using Leopard (except the MBP in the center). Also, MacBook uses 1GB RAM.
- You can check the bold Xbench scores to compare the cumulative results for each test.
