Apple’s new ‘Santa Rosa’ MacBooks significantly faster than previous MacBooks

“Apple quietly released new MacBooks last week which feature (among other things) the Santa Rosa chipset and, for some models, a slightly faster processor,” reports Primate Labs, developer of Geekbench, a cross-platform benchmark for Linux, Mac OS X, and Windows.

“While the new MacBooks have only modest processor performance gains over the previous MacBooks, the Santa Rosa chipset helps the new MacBooks achieve much more impressive performance gains over the previous MacBooks; memory performance is up almost 15% while stream performance (which relies heavily on memory) is up almost 25%,” Primate Labs reports.

The comparison pits the following systems against each other:

MacBook (Mid 2007)
• Intel Core 2 Duo @ 2.00GHz
• 1.00 GB 667 MHz DDR2 SDRAM
• Mac OS X 10.5 (Build 9A581)

MacBook (Late 2007)
• Intel Core 2 Duo @ 2.20GHz
• 1.00 GB 667 MHz DDR2 SDRAM
• Mac OS X 10.5 (Build 9A3110)

  1. Curious. If I were to tell you your health insurance rates were to increase 25% (heck, how about only 15% as that happens to be the rough medical trend) would you still think that’s hardly worth noticing? I honestly hope so. Because I’ll never waste my time granting rate reductions for anyone ever again because 25% is a modest change and hardly worth noticing accordin to you.

  2. I highly doubt any human being will be able to discern a difference in speed between one of these macbooks and a macbook from last month. When your computer’s CPU is already running at 2000MHz, adding another 200MHz does pretty much nothing.

    I also upgraded from a CD MacBook on the day they were released. The speed difference is AMAZING to me. I also upgraded to the max of 4GB of RAM. I actually had to slow the tracking speed down because the cursor was moving too fast….

    I’d call that significant!

    Also, the new graphics card is wonderful. I can play Halo with all the graphics parameters set to maximum and it plays smoothly.

    Enjoy your when you get it. I am.

  4. While a 10% to 25% boost in performance may not be noticeable, that much of a DROP in performance would hardly be ignored. Just because you can’t “see” it does not mean it isn’t there, isn’t important. What may be more important than the 10% boost in CPU speed is the 15% to 25% boost in over-all speed. This suggests that NO change in CPU speed would still amount to a 5% to 15% boost in system speed. Normally, system speed lags behind boosts in CPU speed.
    BTW: if you are used to waiting ten minutes for a CD to rip in iTunes, wouldn’t you be glad to see it rip in only seven or eight minutes instead?
