Centrino 2 Exposed: A Name Deserved?

Centrino 2: The Curtain Pulled Back

A Platform: Defined

Like its predecessors, Centrino 2 is defined by four key components: a processor, chipset, wireless networking solution, and wired networking controller.

The Santa Rosa platform — the one just before Centrino 2 — began its life relying on Intel’s Core 2 Duo processor. Manufactured at 65 nm and operating on an 800 MHz front side bus, it did its job well enough, but was replaced earlier this year by the much more attractive 45 nm Core 2 Duo. Armed with more cache and higher clock speeds, that quiet Q1 refresh represented a good time to upgrade. Intel ups the ante even higher with Centrino 2 by pushing a full lineup of chips employing 1066 MHz front side bus speeds and TDPs of either 35 W or 25 W.

The Mobile Intel 45 Express chipset family displaces the old GM965, to which we say good riddance. Gaming of any sort was wishful thinking on the Intel GMA X3100 core. We can only hope that 3D performance gets a much-needed boost this time around.

Less prominent is the replacement of Intel’s 82566MM/C Gigabit Ethernet chip with a newer 82567LM Gigabit controller, likely tied to the new out-of-band management support Centrino 2 introduces. There are a couple of new wireless options, referred to as the Wi-Fi Link 5100- and 5300-series cards. Intel also plans to launch WiMAX/WiFi Link 5150- and 5350-series cards later this year with built-in support for, of course, WiMAX.

Lastly, Centrino 2 supports a second generation of Intel’s Turbo Memory technology code-named Robson 2. The first time around, Intel armed its Santa Rosa platform with either 512 MB or 1 GB NAND flash cards designed to work specifically with Vista’s ReadyDrive and ReadyBoost features. While Intel hasn’t said much about Turbo Memory as it pertains to Centrino 2 (perhaps because the technology never really demonstrated compelling gains?), we do know that the platform will support optional 2 GB Turbo Memory kits, and later, 4 GB kits. We can only hope that the larger partitions for ReadyDrive and ReadyBoost translate into palpable gains.

    The Montevina chipset also introduces support for 8GB of RAM. IMO that's a major advantage of the Centrino2 and should have been mentioned in the article.

    While 4GB more than enough for now, it might not be enough in 2-3 years.

    Thats nothing close to a revolutionary upgrade like the core2 from pentium4, only FSB and some memory upgrade on the motherboard; PC6400 is so last year for desktop. Certainly do not deserve the name change, i think just a marketing attempt try to stimulate the sales.

    Yeah, fairly underwhelming overall--at least until we see hardware from Intel.

    I would like to point out that a Z06 gets better mileage (city and highway) than a GT-R, V8 vs TT V6, while both having very comparable power and lap times depending on the track style. Just putting it out there, because I know quite a few were thinking it. Haha.

    I'd argue that it depends on how you're driving the car ;-) I have a much easier time burning through a tank in my V8 than I ever did the bi-turbo V6.

    Ok, yes many V8 suck a lot of gas often being paired to heavier vehicles. But I would still wager a quality V8 vs a quality twin turbo V6 have very similar appetites. A very nitpicky thing to say, I will admit.

    No worries ;) More than anything I was trying to make a brute force vs. finesse analogy--probably could have picked a better subject, but I'm a car guy.

    "The Lost World (what a horrible sequel that was)."

    I'm sorry, is this a blog?

    If you're going to put your opinion about all sorts of silly things in articles, then please post the article as a BLOG and not some type of news story. I think we (the readers) have been over this.

    Thanks for the feedback!

    Intel also promised a mobile quad-core in H2 of this year. I'm hoping that with some newer gpu offerings (read beefy) there will be some high power gaming laptops to choose from this holiday season...

    isnt finesse a noun?

    It can also be used as a verb ;-)

    So, does this mean that the Compal JHL90 whitebook is strictly Montevina and not Centrino 2?

    Also, I was wondering if this new centrino 2 platform will support the next batch of cpus beyond the penryn mobile series or will an update be needed like Santa Rosa had.

    One last question, :). Is there any real performance difference between say a t9300 800Mhz FSB and an update t9400 1066Mhz FSB, and maybe even a P9500 1066Mhz FSB?

    I know these are pretty technical questions and would appreciate any and all responses. :)

    Orange,

    You'd need to built the Compal whitebook up using the full complement of Centrino 2 components--it's a Montevina notebook, though.

    Re: CPUs: If you're talking about the upcoming Nehalem-based processors, then no, this platform will not be able to support them.

    Hopefully we'll know soon enough about the advantages of the faster front side bus. Intel didn't have any hardware ready for the launch, so we still don't know.

    Thanks!

    Thanks for the info cangelini, I guess I need to choose between the JHL90 and the older FL92 now. Decisions, decisions.

    mrmessmaI would like to point out that a Z06 http://en.wikipedia.org/wiki/Corvette_Z06 gets better mileage (city and highway) than a GT-R, V8 vs TT V6, while both having very comparable power and lap times depending on the track style.

    There are major differences between the Z06 and GTR. for one the Z06 is ~750lbs lighter. The Z06 is also 2wd unlike the GTR's 4wd. Inherently a turbo driven engine will be more fuel efficient if driven at lower throttles since the vehicle will operate as a naturally aspirated smaller engine with less reciprocating inertia, friction, etc. Trim 750lbs and use a rwd only on the GTR and the MPG would most likely tilt toward the GTR.

    For example a Caparo T1 with 550hp will run circles around a z06 (and just about everything else)and get 33MPG. Is that because it's 1000lbs lighter than the Z06, you decide.

    The analogy as to cpu(s) and chipsets is fair. Since a smaller process cpu or chipset is like a smaller v6 engine. While the increased clock rates yield greater performance, such as boost from a turbo. Turbo has been a cliche term used for computer components for decades so this statement just continues the trend.

    I like Intel, but to give them a "pass" on graphics and video is a little incredible without a real review. To give them a pass on it when they are at the center of the Vista graphics class-action lawsuit, have a well known track record of low performance on compatibility and games, and there are reported issues on C2 HD video (AnandTech) amazes me.

    They certainly don't get a pass. Not knowing what the integrated core is capable of, we can't pass judgment one way or another. Absolutely we'll be taking a look at some of the Centrino 2-based platforms once they become available next month.
