First benchmarks: MacBook Air is the slowest Apple machine on the block
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.
