Intel’s Mobile Core i5 And Core i3: Arrandale Is For The Rest Of Us

Mobile Chipsets, Refreshed

Along with its 11 new mobile processors, Intel is also launching a quartet of platform controller hubs. From lowest to highest, in order of pricing: HM55, HM57, QM57, QS57. Add in the PM55 already being used to support Clarksfield processors and you have a total of five mobile chipsets from which to choose in the current-generation Calpella platform.

Given the degree of integration on the processor side (leaving relatively little for core logic to handle), the differences between these five SKUs are fairly subtle, so let’s start with yet another chart and break them down from there.

Right off the bat, we see that the QM- and QS- models are intended more for businesses than consumers. AMT 6.0 with Remote PC Assist is used by IT administrators and VARs to remotely manage and secure hardware assets—a great feature if you’re the one responsible for keeping tabs on pricey notebooks, especially in larger organizations where inventorying equipment is particularly difficult.

HM57 and HM55 (like H57 and H55 on the desktop) are more relevant to the broader market of consumers.

HM55 includes 12 USB 2.0 ports, six 2.5 GT/s PCI Express links, four SATA 3 Gb/s ports, support for four PCI devices, Anti-Theft technology, and the AHCI component of Intel’s Rapid Storage technology suite (not the software-based RAID support). Of course, Intel also adds its management engine, enabling the protected audio/video path needed for Blu-ray video playback and high-def audio bitstreaming via integrated graphics.

HM57 is available in two different forms. Both step up with 14 USB 2.0 ports, eight PCI Express links, six SATA ports, up to four PCI-based peripherals, and the same protected audio/video path. The “lower-end” version employs up to a 4MB firmware package, while the “higher-end” implementation uses as much as 8MB of space. The larger firmware makes room for Identity Protection technology and Remote PC Assist technology for the consumer space—a version of what Intel enables on the QM57 and QS57—allowing befuddled home users to hit a button, key in a code, and get remote support from a remote tech offering service.

As you’ve no doubt already realized, all four of these platforms are very similar from an I/O standpoint, and differentiated by turning switches on various value-adds on and off. Fair enough—that’s the way it’s destined to be anyway as an increasing amount of technology is integrated into the processor itself.

    Well played, Intel. You've been knocking it out of the park lately, keep up the good work.

    I'm looking forward to getting an HP laptop with the Arrandale Core i5 processor in the near future.

    It's going to be interesting to see the performance/battery time of the LM and UM processors as I'm in the market for a thin-and-light myself.

    Performance is good but I'm hoping for a viable update to the CULV offerings of yesterday.

    Looks like there are finally some replacements for the Atom, at least in efficiency anyway. Too bad the price is currently too high for the UM versions of these processors to make their way into netbooks. I would guess that even the i5-520UM would destroy the Atom in every benchmark, except maybe power consumption.

    C2D was one of the longest living platforms. But newer tech will replace slower processors.

    Keep it up intel. I do hope that AMD will release some new chips that will be able to compete with intel offerings.

    ^^^ true that. arrandale will further diminish AMD's role in the mobile processor market. and there's nothing coming up before may.

    Chris, the dv4 series from HP has a 12-cell extended battery available as well rated for 94Wh 2.2A. Once HP makes the transition to Arrandale, all else being same, you can expect the dv4 to hit 8-10 hours easy.

    Thanks for the tip Lucious. I didn't have the higher-capacity battery available to test, but I'd absolutely love to see 8-10 hrs. real-world from an Arrandale-based machine.

    Good bye NVidia ...

    That chops them completely out of the mobile graphics market for the masses ... Intel will pay the RIGHT OEM's some "adjustment" just to make sure their "Strategy" is right to ensure AMD's mobile market is thin and restricted to the backwaters of Bejjing.

    Wish you would have compared it to Intel Extreme Graphics 2 or something.

    These comparisons aren't very useful. Was really curious how it stacks up against other competing integrated graphics.

    Like... what is the Vista / 7 Aero and Gaming graphics score?

    Have a look at Page 8, where HD Graphics is compared to the previous-generation GMA in Vantage and WoW. You're not going to get much else out of this, to be honest...

    Ok so we get 20% improvement over a 2.53GHz C2D but what about the fact that C2D goes to 3.06 GHz and 3.33GHz in extreme edition, but the best arrandale is only 2.66Ghz?

    Also the integrated graphics can barely match the 9400m that is 1-2 years old.

    The battery life is the same or worse...

    What is so great about this chip?

    Personally I'm not at all impressed and find it a step side ways or even backwards.

    ASUS EFI? can it load the apple one?

    Just because the older C2D's have higher clocks doesn't necessarily mean they are better. Advances in the micro-architecture sometimes leave clock freqs irrelevant. An i7 920 @ 2.66 will beat a Core 2 Extreme QX9770 @ 3.2. But to be sure I guess we will have to see the highest end Arrendale vs highest end C2D.

    The integrated graphics do suck, but at least now we have a choice in some laptops where we can switch from the integrated to dedicated, saving battery life when needed and boosting performance where needed. It adds flexibility basically, I'm sure Intel was aiming more for that rather than performance in 3D games.

    What I really want to see is the ULV versions of this chip. I'm hoping whenever they start coming out, it'll push down the prices of older Ultra-Portable laptops around the 12-14" sizes. Certain ones with the C2D SU7300 and 4GB of RAM can be found for around $550 today. If these prices go down far enough, netbookks will be obsolete in my mind.

    Thank you for another great article. Where else could anyone get that kind of information in such a perfect way of writing? I have a presentation next week, and I am on the look for such information.I will recommend my friends to read this.I will bookmark your blog and have my children check up here often.I am quite sure they will learn lots of new stuff here than anybody else!....There is also a lot of visual symbolism that is sometimes subtle, sometimes not so subtle...

    Interesting that no mention was made of how Apple has been building Core 2 Duo notebooks that will play 4 movies on a single battery charge, while the i5's and i7's are great, I don't think Intel's Duos can be blamed for your notebook's barely being able to play a single movie. (note Apple is now making notebooks with the i5 and i7 processors which also can run all major operating systems)

    Hey, Did you know these Arrandale CPUs are starting to pop-up already? I've noticed this review for the Core i5-520UM today, google says it's new: http://www.netbooklive.net/intel-core-i5-520um-benchmarked-on-asus-ul30jt-3493/ . Hopefully It's ok to post links in here, as they are related and help the readers of this post.
