    Anandtech offers a direct comparison between the existing Merom processors that currently power the MacBook Pro line, and the just-released Mobile Penryn processors. Apple is rumored to be working on MacBook Pro revisions as early as Macworld Expo next week that use these new Intel processors.

    Anandtech was able to provide a direct comparison between the two processors:
    With just the processor change alone, the new Penryn laptop offered 5-10% more battery life on their benchmarks. Meanwhile, the new processor saw 1 - 8% speed boosts on common tasks, and up to 40% improvements in applications that support the SSE4 instruction set.

    Apple's MacBook Pro is currently available in 2.2GHz, 2.4GHz and 2.6GHz speeds. The last major revision of the MacBook Pro was in June of 2007.

    Here is hoping new MacBook Pros at Mac World, followed by new MacBooks and iMacs next summer.

    Here is also hoping Photoshop adds SSE4 support for common filters.

    To me this chip revision is more about the 45 nm technology, with its associated chemistry change, and an incremental improvement in power management, and the SSE4 language for bleeding edge apps, which do not effect most people, are the geek-kicker. Pro apps.

    The notable thing beside better power usage is far better likelihood of deeper back-end price drops due to far smaller die sizes. Given Apple uses long term supply agreements with back end discounts, this product was designed more for manufacturability than even for features, which are strong enough indeed.

    Apple is winning the vendor-supplier game, and Intel is reaping the benefits.

    yea santa rosa is a subgroup of the merom processors.

    Penryn is a new 45nm chip.

    i know what penry is. Though santa rosa chips are already 45nm and use the high k method that im guessing was carried over to penry as well

    What OS? Windows Vista I presume?
    Is Vista fully 64bit?
    Is Vista optimized to handle multiple processors/cores?
    Can it throttle processor utilization and power consumption?

    Sorry, I'm fulla questions and sorta feel like 10.5.2 will address some of these issues.
    Penryns will show even better improvement with OS X.

    What applications/types of applications take advantage of this?

    nope
    merom processors in the santa rosa platform is using 65 nm, not 45nm

    Yes.


    Yes.

    Yes.

    Not sure if it does it on it's own or if it interfaces with SpeedStep on the CPU, but it does do it.


    Mind you, I still am not impressed with Vista even on 8-cores with 4GB, but I was running the 32-bit Vista edition.

    OK, so...

    >45nm chips means less heat yes (among other things)?

    >What would take advantage of SSE4?

    The SSE instructions are of most use to software that process large streams of audio or video media. Doing things like changing color spaces, scaling pixels or encoding a ripped CD to MP3

    Apple might modify Core Image or other "core" libraries to use SSE4 and then software that uses these libraries would be able to take advantage without need to be changed. Right now I think Apple is the biggest user of these libraries with programs such as Preview, iPhoto, Aperture Garage Band and so on. I think Adobe uses their own image processing code.

    Use of SSE4 in software would have to wait until the SSE4 hardware is widely available or else how could Apple run a beta test?

    So far the benchmark Intel provided Anand for that article, although it can be assumed more will

    "...40% improvements in applications that support the SSE4 instruction set."

    Damn. That's not bad. Wait, what's SSE4 Instruction set?

    What kind of battery is in those Dells?!
    4.5 to 7 hours of run time seems like a dream!

    I think it's cool but everyone needs to set realistic expectations for something like SSE4.

    1. It will take a while (a good long while for some) apps to get recompiled with this support. And many will never get it for assorted reasons.

    2. You can't rebuild an entire OS around a new instruction set, so see #1 when considering impact on OS X. Some parts will get a boost, many won't.

    I only post this because I was on another forum and apparently SSE4 cures you male pattern baldness, improves your gas mileage, pleasures our woman while you are at work and prevents dandelions in addition to speeding up some instructions.

    That said, I'll take any boost I can get so those who held out for Penryn get a little something for the wait.

    I don't know about Vista, but Windows XP does that on my Shuttle XPC system. I downloaded and installed AMD's "Cool & Quiet" software to provide the feature. When idle, the system clock slows to about 40%, jumping back up to 100% when active.

    I don't know how much power it saves, but the fan runs slower and the air exhausted out the back is noticeably cooler.
    Santa Rosa is a mobile chipset suite (using the "Centrino" brand) that incorporates a particular graphics and Wi-Fi chipset in addition to the CPU. It supports "Socket P" processors. Originally, this was just Merom, but Penryn is also supported (it's unclear from the Wikipedia article if the refresh for Penryn compatibility involves new chips or just a firmware update.)

    SantaRosa is a platform

    SantaRosa is a platform. A platform includes a set of MCHs, ICHs and CPUs.

    Merom and Penryn are CPU families. It is up to intel to continue calling SantaRosa platform the new combination of Penryn + MCH + ICH.

    Cheers,

    They are used extensively by many parts of Mac OS X, including the desktop and related UI components.

    Additionally, any code using the Accelerate framework (instead of direct SSE calls), should be able to take advantage of the new capabilities, as soon as Apple releases an update with the capability. (For those who don't know, the Accelerate framework wraps a wide variety of SIMD-type operations, so code can use them on both PPC and Intel systems, mapping to either AltiVec or SSE instructions, as appropriate.)
    Not necessarily. Apps that currently use the Accelerate framework should be able to take advantage as soon as Apple updates Mac OS X. They shouldn't have to be recompiled.

    Code that directly makes SSE/2/3 calls, of course, will have to be updated, but there may not be that many apps in this category. Accelerate has existed since Mac OS X 10.3, and Apple has been encouraging its use since then. I suspect that Adobe will be one of the few major app-suppliers that will need to update their code for SSE4.
    Mac OS uses the Accelerate framework for those subsystems that use SSE. They should all start using the new instructions as soon as Apple updates the framework.
