    Apple lists the i5 3.6mhz as having Turbo Boost AND HYPER-THREADING.

    A.Intel lists the i5 3.6mhz as ONLY having Turbo Boost.

    All Intel® Core™ i5 Processors feature:

    * Intel® Turbo Boost Technology♦
    * Enhanced Intel SpeedStep® Technology
    * Execute Disable Bit°


    B. Intel lists the i3 as ONLY having Hyper-Threading.


    All Intel® Core™ i3 processors feature:

    * Intel® Hyper-Threading Technology¹
    * Intel® Virtualization Technology±
    * Intel® Smart Cache
    * Execute Disable Bit°
    * Intel® 64 architectureΦ



    http://www.intel.com/products/processor/corei5/specifications.htm

    Apple lists each processor as having both features. I assume that Apple conveniently failed to specify the above facts making it seem like the i3 and i5 each have Turbo Boost and Hyper-Threading.

    Can anyone set the record straight on this?


    From Apple's Description:

    Get amazing performance from the Intel Core i3 or Core i5 processors, which feature two processor cores on a single chip. Choose the speed and processor you want.

    All iMac models include processors from the blazing-fast Intel Core “i” series, featuring an all-new processor architecture that helps boost performance over the previous generation. Advanced features include:

    * 4MB of L3 cache, which increases performance by keeping data and instructions in a fast-access cache that is available to all processor cores.
    * An integrated memory controller, which allows faster access to data stored in memory by significantly increasing memory bandwidth and reducing memory latency.
    * Turbo Boost, a dynamic performance technology that automatically speeds up the core in use when the other core isn’t needed.
    * Hyper-Threading technology, which allows two threads to run simultaneously on each processor core, providing four virtual cores for increased performance.

    Which processor speed is right for you? The more time you spend using processor-intensive applications — such as video processing, image editing, and 3D rendering — the more you’ll benefit from a higher-speed processor.

    Processor

    * 3.20GHz Intel Core i3 [Subtract $200.00]
    * 3.60GHz Intel Core i5

    I should have made the topic just for you! j/k

    Thanks for the clarification. You are right! I've been looking at the wrong processor chart.

    However Apple should still specify that the i3 does not have Turbo Boost.

    Apple doesn't tell us the disadvantages, only the advantages ;) They don't even tell us that the GPUs are mobility parts lol :D They definitely should though
