    Hey guys, I am now a proud owner of a MacBook Pro Penryn 2.4ghz entry level. I noticed that it has only a 3MB L2 Cache... so I am quite worried.
    I know the MBP before the revision had a 4MB L2 Cache, so does that mean its technically better or faster than the new Penryn 3MB L2 Cache? Let me know, thanks.

    It will be about the same. Contrary to popular belief there ARE some updates to the CPU itself that make it a bit faster but the smaller cache will offset that. I believe I saw some benchmarks that show the penryn based CPU is still a bit faster though. Again nothing you'll notice in daily use.

    Yeah should be about the same. There are some tweaks to the CPU. Also, SSE4 support was added so any apps that specifically take advantage of those extensions will actually be significantly faster than the older version. But as stated, should be about the same overall.
