Apple MacBook Pro Penryn tests: a little more speed, a lot less heat
Sure, 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 this brand new machine at let 'em crank for a half an hour. Our test 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 over 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.
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). MacBook uses 1GB RAM, Penryn MacBook Pro uses 4GB RAM.
You can check the bold Xbench scores to compare the cumulative results for each test.
