iMac benchmarks

PrimateLabs has posted a series of benchmarks for the new Core 2 Duo-based Mid-2007 iMacs. The site tested a an iMac (24-inch Mid 2007) with an Intel Core 2 Duo at 2.4GHz, 2GB 667 MHz DDR2 SDRAM and Mac OS X 10.4.10 (Build 8R4031) against previous generation iMacs (24-inch) with Intel Core 2 Duo processors at 2.33GHz and 2.16GHz. Overall, the new 2.4GHz iMac posted a score of 3243, compared with 3049 for the older 2.33GHz model and 2898 for the older 2.16GHz model. Unfortunately, the article neglects to do any graphics benchmarking with the new ATI cards that are included in the Mid-2007 iMacs.

The comparison concludes "The latest 24-inch iMacs have two major advantages over the older 24-inch iMacs; they have faster processors, and they use the new Santa Rosa chipset (instead of the Napa chipset used in the older 24-inch iMacs). The faster processor helps increase both integer and floating point performance, while the faster front-side bus on the Santa Rosa chipset helps increase both memory and stream performance."

    the new chipset

    doesn't seem to make that much of a difference ??

    You mean the inclusion of a faster chip makes the computer relatively faster? Man, I never would've guessed!

    big comparison...

    a 2.16Ghz chip is slower than a 2.33Ghz chip is slower than a 2.4Ghz chip - who would have guessed ??

    The point is how much faster it is (by this test, anyway). The chip speed (from the 2.33 to the 2.4) is increased by 3%, but results in a performance increase of 6.36%. That's worth noting.

    However, comparing the 2.16 chip to the 2.4, the chip speed is 11% faster, and the performance is 11.9% faster - you'd think it would be better than that, with the new chipset.

    more complete benchmarks

    I suggest heading over to where they just today posted a much more complete benchmark tests on these new iMacs, and even compared them to the top end iMac G5, before it went Intel, as a comparison. They also test the video card, which these benchmarks leave out.

    Waddabout the 2.8GHz iMac

    I'd like to see numbers on the 2.8GHz model with the unlocked multiplier. Oddly the numbers look okay, but-outside of the redesign-this upgrade looke like a speed bump, performance wise.

    Am I missing something? If I were looking to buy and iMac, I'd have to wonder if the mini weren't the better performance for dollar bargin.

    Just how fast would be this "extreme" iMac?
