Penryn MacBook Pros: Performance Comparable, Battery Life Greater
As described before, the biggest change in the new MacBook Pros is the use of a 45-nm Penryn CPU as opposed to the older 65-nm Merom CPU. Despite some differences in L2 cache, Anandtech found benchmark performance to be neck and neck:
Overall, the performance differential ends up being a wash - there are some cases where Penryn is faster at lower clock speeds, while others where Merom manages a win - much as we expected.
One measurable advantage of the new processors, however, is an extension of battery life, with improvements ranging from 7-15% longer than its predecessor, with an absolute increase in battery life of 37-67 minutes in their web browsing test.
It looks like Penryn is good for a 7 - 15% increase in battery life over similarly configured Merom systems. The improvement alone isn't enough to warrant an upgrade but it's a nice improvement over the previous systems given that you get it at no additional cost. Ah, the beauty of innovation.

was it really worth the wait?
for a decently longer battery, I think so!:cool:

Ah, yes. 7-15% percent is 17-36 minutes – assuming a batteri life of four hours. And who can honestly say they're getting 4 hours on a MBP pro? More realistically, you get 2-2,50 and with the latter, it's a mere 10-22 minutes.
Now, don't get me wrong, _any_ enhancement is great. But worth the wait?
Nah …

It shuts up the moaners for a month or so... :rolleyes:
and they didnt even think to make the trackpad bigger!
Come June/July when we get the next Intel chips with possibly wimax, I think we will see a revolutionary jump not an evolutionary bump.
This was an interim step for the MB/Ps.

Bingo! In fact I find it quite likely that Apple had no intention of pushing this update out but was forced to by Intel wishing to cut down production of Merom.
