  1. Attention to detail... by WIAKywbfatw · · Score: 5, Insightful

    From the Apple link:

    Each of the four thermal zones is equipped with its own dedicated, low-speed fans. Apple engineered the nine fans to spin at very low speeds for minimum acoustic output. Using 21 different sensors, Mac OS X constantly monitors component temperatures in each zone, dynamically adjusting individual fan speeds to the appropriate levels for the quietest possible operation. As a result, the Power Mac G5 runs two times quieter than the previous Power Mac G4 enclosure.

    Nine fans and 21 sensors, generating half as many decibels. Now I'm not an Apple fan-boy but that's the level of attention to detail that seperates Apple from Dell, etc.

      That's not attention to detail, that's just a different methodology. Not going the cheapest way possible. For attention to detail, notice the lack of cables all over the place inside the computer, or how the little capacitors and other components on the boards are colored to match the internal design. It may be silly in some ways, but when designers care enough to try and make the inside of a computer beautiful, I find that kind of comforting.

      True. I've found that engineers who don't care about how things look on the outside generally don't care too much about how they work on the inside either. Meaning no features that aren't in the spec, no effort expended to fix designs that sound good but won't work in the real world. So we get things like the flimsy door covering the ports on the front of a Dell precision desktop (ports which are impossible to see and useless if you put the tower on the ground, like everybody I work with)...

      Apple's design is more than simply "superficial." It's thorough. When I was looking for laptops, I found plenty of really nice machines with big, fast, hot processors that only got a little more than an hour of battery life. And I found machines with nice, big 17" screens that had super high resolutions, but were only viewable from a tiny angle. And any machine that had similar features and speed were close to two inches thick and weighted upwards of 15 pounds.

      I only found one that was even close to the footprint of my 15" with similar specs, and it was the Apex Ferrari. Now, since I'm not going to buy a gaudy red laptop with a ferrari logo on it, I only had the one choice :).

    The dual 1.8 and dual 2.0 GHz machines come with an "NVIDIA GeForce FX 5200 Ultra" graphics card. Isn't that card pretty low-end (or midrange at best)? Is it just me, or should a 2,000+ dollar machine come with a decent graphics card?

      Think of it this way, the target market (A graphics professional- Photoshop, Quark, Illustrator, InDesign) has no need for 3D acceleration. The NVidea card in the G5s have plenty enough power for Quartz Extreme, so they put them in.

    ...as much as I care about the liquid cooling part. I remember liquid cooling my crappy little celeron, thinking it would never go mainstream because of my belief at the time that water + electricity = bad.

    Now, we've got liquid cooled technology backed by Apple. It's pretty sweet, considering you either have to buy a specially designed freon pumping case, or a $500 video card to reap the benefits of this kind of cooling.. Now all you've gotta do is buy a $3000 Mac.

    Sarcasm aside, I think this shows that soon, the PC's on the shelves will mostly all be using some sort of heat pipe / water cooling technology.

    I'm not a Mac fanboy, don't own one, but this really goes to show that Apple can and does set standards for personal computing. With major backing like this, it's only a matter of time before it trickles down to where everyone can be using it for a relatively cheap price. Way to go, Apple.

    Clock speed doesn't mean "nothing", it's just not the sole- or even the most meaningful- measurement of over-all system speed. People have mearely noticed that, with all the bottle-necks in a system, merely bumping up clock-speeds without improving the over-all architecture gives deminishing returns.

    What a G5 2.5 Ghz would be equivalent to in terms of Intel or AMD depends on what you're doing and how you benchmark. It really doesn't matter too much, though, unless you're trying to start a Mac vs. PC flame war. It's like comparing Apples and Oranges.

    It's just to keep it quiet.

    It's a common misconception that Apple *needed* the elaborate cooling mechanism they designed for the G5. They didn't design it to keep the chips cool, they designed it to keep the chips cool quietly. The G5, I'm told, actually runs cooler than the high-end P4 chips. It runs hotter than the G4 for sure, but it's not like there's a miniature fusion reactor in your tower or anything.

    pardon me, but where on that picture is a pump?
    is the RADIANT GRILLE or the CPU's the "PUMP"?

    the text doesn't say there is a pump either, *The dual 2.5GHz Power Mac G5 features an innovative liquid cooling system that's more efficient than a traditional heat sink. This system provides a continuous flow of thermally conductive fluid that transfers heat from the processors as they work harder. The heated fluid then flows through a radiant grille, where air passing over cooling fins returns the fluid to its original temperature.*

    all this implies that it is, in effect, a heatpipe without a pump driving the system. the diagram implies it as well.

    It makes more sense to not have a pump anyways, besides, if they did use a pump this wouldn't be that innovative at all(because this is exactly where a heatpipe cooler could/would rock).

    well it's also the chip's design. the Apple (and IBM/Moto) designs (and AMD to some extent) "do more work" per clock cycle. that's part of the reason some are better for some processes (though software is key too). think of it like a racecar vs a truck. a racecar revs really fast and flies, but carries one passenger. a truck revs lower but can tow a house. if you had a relay race of the two that had to transport 300 people across a distance the truck could win since it could haul everyone in one or two trips. it's the same way the G5 (or G4) tries to "do more" with every clock cycle compared to Intel just trying to go really really fast.

    it really comes down to attacking the same problem from different methods.

    Modding is (usually, I'm sad to say) not about getting "better", but about getting "flashier" (at least in some 1337 g4m3r teenagers' eyes).

    Make the RF-shielding case useless, it looks so much flashier with a frigging HOLE in the side. Fans with LEDs inside aren't more quiet nor do they push more air, they're flashier. UV-lighting inside your case doesn't push more data across the buses, it's there to be flashy. A fan grille in the shape of a biohazard sign doesn't obstruct airflow any less than a normal grille, but it's flashier. The graphics card with a stupid dragon / monster / anime babe printed on its fan casing is more expensive than a more normal looking computer component, but it's flashy (if you lie on the floor looking up, so you can see it when it's installed and turned upside down).

    Though personally I think it all looks more ridiculous and stereotypical than "flashy".
