Centrino Duo, Buy or Wait? 251

Posted by Zonk from the choose-wisely dept.
pillageplunder writes "BusinessWeek Columnist Steven Wildstrom answers a readers question on whether or not to buy a laptop with the new Intel Centrino Duo processor. The reader wanted to know if the new chip would be up to handling the Graphic requirements of Microsofts new Vista OS, and whether or not it would cost more. His take? Regarding price, probably not, about performance, right now there is no real way to know for sure. He does a decent job of outlining bug issues with new chips, and what the various vendors say/feel about this chip."

      RAM will be the deciding factor for when we move to 64-bit processors.

      Don't believe me? Ask yourself this: why is it all of the big room server clients wanted a 64-bit chip years and years ago? So that they can saturate their servers with multiple gigs of ram; CPU archetectures might change day to day almost, but RAM archetectures usually last a long, long time, and as time passes, prices go down. So that big iron server that you purchased with 4GB of extremely expensive ram at the time, you can now saturate with 16GB of dirt cheap ram and still be in the top 80% performance bracket.

      How does this translate to home users? When home users hit, and can no longer exceed the 4GB limit, then and only then will we see a desktop push to 64-bit. And we've still got a lot of ground to cover until then; some top end computers are running 4GB now, but by and large 512MB is the standard, with 1GB now being the recommended ram total. Ram scaling-wise, I predict we won't hit that "need for 64-bit" number until 2009, but by 2008 or earlier, all desktop CPUs will be 100% 64-bit anyways.

      How does that tie into today's discussion? Perfectly; by 2008, your laptop will be obsolete, that's a given. So that means purchasing a system now will likely carry you until the 64-bit revolution. All and all, this means that 64-bit is a non-selling point to a Laptop consumer at this date.

The only "tangible" advantage is the ability to manage more system RAM.

      Others have pointed out that you're wrong, but I wanted to explain why. The world is not rapidly moving to 64-bit except in the server space where memory is a concern. However, Intel chips since the Pentium Pro have supported 36-bit memory addressing which breaks the total 4GB barrier anyway. The reason 64-bit is not rapidly taking off is that 64-bit introduces a bigger pipe but offsets the gains with bigger pointers and more cache bloat. Most of the performance gains you see in benchmarks comes from the fact that in 64-bit chips, SSE3 is a baseline and so you can target it in your code, as well as the extra registers which are added by the vendor and not related to being 64-bit.

      In 32-bit code where SSE optimization is implemented, a lot of 64-bit gains disappear. This is particularly interesting for the Mac since their baseline Intel spec will always have at least SSE3, so all apps can target it from now on. Doing 64-bit math doesn't require a 64-bit chip either, as SSE goes up to 128-bit. The real reason you'd want 64-bit is if you're running a server that needs a very high amount of memory.

      64-bit gaming has been the most amusing to me, watching as CryTek and AMD teamed up to sell more chips and desperately advertised 64-bit Far Cry as better than its 32-bit version by adding higher-res textures here and there and tweaking the visuals, even though absolutely none of that has to do with being 64-bit and everything to do with your video card. 64-bit Half-Life 2 is actually slower than its 32-bit version according to the benchmarks. Slashdot has an article in its archives about how 64-bit gaming has been overhyped to gamers.

      There are times I wonder if 64-bit will die as a fad this year and become an unused set of instructions that only server admins use. It's certainly got all the makings of a tech fad. I think the novelty is wearing off and people are realizing 32-bit is just fine and that there is nothing inherently better about being 64-bit, other than giving AMD and Intel a marketing reason to sell you new chips. I can't think of any reason a desktop computer user today needs a 64-bit chip. Microsoft, of course, is very vocal about wanting to put everyone on 64-bit chips, and the reason for that is that the majority of Windows sales come from pre-installations on OEM computers, so if they can convince people to buy new computers that have new chips in them, they sell more copies of Windows. I think they'll have as much success with that as they did with the XBox 360 launch. Ahem.

      As a sidenote, Apple handled 64-bit in OS X Tiger by keeping the GUI 32-bit, but allowing 64-bit processes to be spawned in the background. This means your app is 32-bit but you communicate with a spawned 64-bit console process (it has to be a console process because the GUI libraries are still 32-bit code). It's so little used that it took a while for anyone to notice when one of the 10.4 updates accidentally disabled 64-bit support...

    When the Meroms come out, the price on the current gen of Centrinos will fall. Snatch up a nice Thinkpad for $1000.

    As long as it'll still run Windows 2000 and Linux, I'm good. I haven't needed anything Microsoft put out since W2K, and I haven't had any need for anything faster than about 1.2 GHz. A bunch of people at work bought tricked-out new 3+ GHz machines in the last couple of months, and I asked them, "Why so fast" or "Why did you buy the $300 graphics card update?" Basically people have become so conditioned that they HAVE to buy the FASTEST and BEST thing out there or their computer is already obsolete before they even start. It's a bunch of crap anymore. Most of these people are just browsing the web, doing email, writing documents, editing photos. A $400 PC or Mac Mini would have been plenty for them. They spent $1500, and threw away a bunch of money.

    I had someone say that a Dell rep told them that they really should get that Hyper-hot $350 GeForce ultra-platinum video card, because she'd need it to retouch photos on the computer. That's pretty reprehensible IMHO. A $30 graphics card or mainboard graphics would have done just fine. I say they practically stole $300 from her.

    Sorry for going OT.
  • Clearly the only rational solution is to buy a Mac.

    I've got a dual-core and it doesn't really help much since pretty much all the software I use regularly is single-threaded. Occasionally the disk io happens in another core from other processing, so for example rar'ing might be say 5% faster than on a single core. It is nice that I can rar huge file without impacting performance of the 'main' thing I am working on, but that doesn't happen very often.

    Overall, the only thing I've really noticed that is significantly faster is Java. Most Java apps use threads, and if nothing else the GC seems to run on the 2nd CPU. For example, the graphics demo takes 100% of both cores if you set the delay to 0ms between frames. That's about the only program I've seen actually use both cores.

    As a side note, I predict with more cores we will see greater use of things like Java. It may run at say 80% C speed, but 80% + 80% is still much more than 100% on one cpu and 0% on another.
    • Not a big multitasker eh?

      It's night/day with me. A dual core system feels so much more responsive, effortlessly gliding from one application to the next as one is entirely isolated to one CPU and the other to the other.

      Of course, I don't own a DC system anymore; the last dual processor system I owned was a dual proc 500mhz pentium III system (might've been xeon, I can't recall; it was my Dell) and I miss it. If it could run today's applications at any kind of speed I would still have it as it was such
      • That's the big reason that I'm drooling over the Thinkpad T60s. It's all about responsiveness (well, mostly).

        I have a pair of Opteron systems at my desk (in addition to the laptop). The dual Opteron 246 unit almost never has responsiveness issues, the Opteron 148 is constantly waiting.

        Just wish the prices on the 265/270s would drop to something reasonable (say $200 each)... I "want" to upgrade my dual 246 to a pair of 270s.

    If you want to run Glass (the GUI) you need to make sure you have a compatible video card. I have found in Vista that the biggest perf issues stem from low memory or not having a compatible video card. Here [nvidia.com] is nvidia's list of supported video cards, note that there are no notebook cards on it right now. Here [ati.com] is ATI's list of supported video cards. If you want the slick UI, just make sure you get a laptop that supports LDDM.
  • ..otherwise you'll end up waiting for eternity to buy as each new technology coming out sounds more promising.

    And once you do buy something, don't check prices.
  • I'm struggling with a decision about which laptop to buy. I'm going to be buying one in the next week, although I might be able to wait a little.

    I want to run FC 5 on it, although I haven't figured out whether linux kernel is ok. Anyone know?
