certain, more speed is great, but on OS X most bumps don’t have an appreciable effect on everyday work (unless all you’re doing is video encoding). We were more interested in what Intel’s Penryn processors can do for the MBP’s heat envelope, so we maxed out both CPU cores in that grade new machine at let ‘em crank for a half an hour. Our experiment machine may or may not compare to a later 3rd-gen MBP in terms of heat efficiency, but here’s the quick rundown:

Core Duo (2.16GHz)

• Peak: 195° F, fans by 5000 RPM
• Average: 185° F, fans about 4900 RPM
• Enclosure (bottom): very hot to the touch
• Enclosure (top): fairly hot to the touch

Penryn Core 2 Duo (2.5GHz)

• Peak: 176° F, fans about 3400 RPM
• Average: 173° F, fans about 2500 RPM (much quieter)
• Enclosure (bottom): warm to the touch
• Enclosure (top): warm to fairly hot to the touch

The usual Xbench tests are after the break.
