    OK, so I picked up my Penryn MBP last night and since I haven't yet shipped out my "old" Merom to its new owner so I thought I'd do a few quick tests - nothing too in-depth, but a few things I was curious about. To keep things simple, the new Penryn is going to be listed as "Mac-P" and the Merom will be "Mac-M" (I hopes its not too confusing!!)

    Here's the basic specs:
    MacBook Pro 'Mac-P'
    CPU: 2.5 Ghtz Penryn
    Cache: 6MB
    Mem: 2GB
    HD: 250GB 5400
    VRAM: 512MB

    MacBook Pro 'Mac-M'
    CPU: 2.4 Ghtz Merom
    Cache: 4MB
    Mem: 4GB
    HD: 320GB 5400 (Western Digital Passport drive that I upgraded)
    VRAM: 256MB

    Boot Up Time:
    Mac-P: 28 seconds
    Mac-M: 31 seconds

    VideoHub Conversion:
    The file that I used is Episode 1, Season 3 of the TV Series Lost. It is a 348.8MB AVI file running 42:15. I converted it using the "Optimize for iPod Touch" setting and did H.264 encoding and Standard Quality.

    Time Elapsed:
    Mac-P: 12:09
    Mac-P: 13:29
    *Note - when I first clicked on the 'Start button in VisualHub, the estimate time for each was 14 minutes for the Mac-P and 16 minutes for the Mac-M, both finished ahead of the estimate.

    GeekBench Testing:
    (testing was done immediately after cold boot - I disabled the Login Items, Shut Down, turned back on and went right into Geekbench and ran the tests with nothing else running).
    Time to Run:
    Mac-P: 22 seconds
    Mac-M: 24 seconds

    Mac-P:
    Overall Score: 3212
    Interger Score: 2830
    Floating Point Score: 4500
    Memory Score: 2412
    Stream Score: 1642

    Mac-M:
    Overall Score: 3074
    Interger Score: 2697
    Floating Point Score: 4244

    Stream Score: 1923

    One other thing I'll comment on is the temperature - I have the iStat Pro Widget on both and both temperature readings were very close to each other (all categories were within 1-2 degrees of each other) before and after converting the video. The CPU temperature both fluctuated from 110-112 degrees before the video conversion to 128-131 degrees immediately after on both computers. The enclosure bottom reading was 90 degrees for Mac-P and 92 for Mac-M. With that being said, the Mac-P feels alot cooler to the touch. It doesn't seem to get as warm as my Mac-M.

    I will be upgrading the Mac-P to 4GB ram soon, so once I do that I'll reference this thread and update with the new scores (probably within 2-3 weeks unless someone wants to donate 4GB of crucial memory to get it done sooner!:D)

    I snapped a quick picture before I packaged the Merom up.. You can't really see much from the picture but they outside hardware is definitely identical!

    (and no, thats not anything plugged into my Penryn screen, its a surge protector on the wall behind it).

    To make this a fairer test (begone images of Cinderalla!), you should rerun everything after swapping RAM between the two machines and averaging the two sets of results.

    I'd thought about doing that but I think it would have opened a bigger gap in the results as it would be comparing a 2.4Ghtz w/ 2GM Ram vs a 2.5Ghtz w/ 4GB Ram.

    Had the 2.4Ghtz been faster in anything I probably would have done the tests that way to really see how much the RAM effected things, but since the 2.5Ghtz w/ less ram was still faster (although slightly) I didn't think we'd learn anything new.

    This is a good test for people on the fence about upgrading to see if it is worth it to them. I'd like to see what the Penryn would get with 4gb of ram.

    I say completely level the playing field!


    2GB ram each!




    Actually, I'd be more interested in seeing what kind of performance the 4gb in the peryn would do.... Think it's significant?

    Yeah, but he said it wasn't scientific... I think he did a pretty good job!

    You both missed akadmon's point. Some of the speed difference might be attributable to the RAM (different make/quality/random-variations). He was suggesting that you switch the RAM between the two machines, such as MBP-P with RAM-M and vice versa, and then re-doing all the tests and averaging the results to be more fair.

    Cheers

    the Merom is gone, I had to ship that one out already, but I should be getting the new 4GB for the Penryn this week and I'll re-run the tests.

    I haven't had time to do the video conversion test yet.. I'm not sure how memory intensive that is, so I'd assume the results would be similiar.

    I was thinking about an upgrade to the new 2.5 but I dont think that it would be worth it after seeing your tests..even if your 2.4 only has 2GB ram. thanxs for your work

    Yea a difference of 138 in the geekbench score is nothing in comparison. I mean my Mac Pro gets 7900, now that's a huge difference! =D

    So, you're paying roughly $1.07 per 'point' and I'm paying about .77 cents per 'point'. I guess its true - you get what you pay for.

    OMG! My Powermac G5 2x2,3GHZ is only a little faster (3127) in CB10 than one Penryn core alone! :eek:
    I'm really hoping my new MBP arrives soon! :D

    Thanks for sharing that information. I'm glad to hear (or read) that Mac-P feels cooler on the touch. :) Now I'm just waiting patiently for the purchasing department to get mine in.

    Well my point is that what's the point of picking up the penryn when you already have a merom 2.4ghz mbp with no differences at all. And your paying .77 cents per point for something almost dead identical from the penryn and merom and you already own the merom. Unless work or someone else purchased for you then why not, of course.

    Nehalem is the only next best thing imo. Penryn=merom. I actually played with my friend's the other day, it is nice I love the trackpad but then again speed/heat wise felt pretty much identical.

    The only reason I did it was because I was able to sell my merom for such a good deal that it didn't cost me anything to upgrade. (Even accounting for the ebay/paypal/shipping fees!) I was all set to pull down my auction until someone bought it with the Buy It Now! :)

    I find it much cooler to use than the previous generation and I'm not imagining it. I can actually use this one on my lap for extended periods without it getting hot. And the top doesn't get nearly as warm either. Pretty damn cool. Literally and figuratively.
