New PowerMac G5s: Up to 2.5Ghz, Liquid Cooled
no_demons writes "Apple have just announced the new, completely dual-processor PowerMac G5 lineup. The models all sport an 8x SuperDrive, whilst new the dual-2.5GHz model also features an 'innovative liquid cooled heat sink,' available in July."
That's great that new G5s are out, but am I the only one a little underwhelmed by the increase in proc speed? (Especially considering the "3Ghz in a year" when they were first announced).
:)
Anyway, sorry to be looking at the glass half-empty.
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.

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?
Of course, the whole point of a tower is that you can replace the card, but when you're already paying 2,500 USD, should you have to?

...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.
More precisesly, Water is a subset of liquid.
Gasoline and alcohol are also liquids, but will have a distictly different effect on you when consumed...
You are in a maze of twisted little posts, all alike.
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.
Everyone's waving the "Innovative" flag about their product design.
I suppose what's really innovative about it is that this is the first time I've ever heard of a major manufacturer shipping systems liquid-cooled.

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.

The anemic RAM included is a good thing. Apple charges far too much for RAM. It's much cheaper to buy your RAM separately instead of upping the RAM on the config you order.
So, A G5 running at 2.5GHz can't be compared to an Athlon running at 2.5GHz on clock speed alone, for example.
However, if you look at Apple's rigged demo (the photoshop test), there's almost a factor of two difference. It's probably not quite that extreme for the rest of the system, but it looks like G5s are faster than the AMD64, clock for clock. Or, they could be the same speed, but the pshop filter is multithreaded.

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).

Already liquid cooled, and in a cool aluminium case, enough case fans for a hovercraft. What is left to do?
;-)
May I ask a serious question? Why mod it in the first place? I can understand that it's fun to make cases fit a "theme" (i.e. If I've got a bunch of racing memorabilia, I might want my case to have flames and exhaust pipes), but outside of that, what's the point? It's just a box. You might as well mod your dishwasher with a plexiglass window in front, and neon lights that catch the water sprays while it's running.
Beyond that, a computer is a machine that you usually don't want to be visible. You see the screen, you see the mouse, and you see the keyboard. Put the mobo in a closet or a hole in the wall for all I care. The only thing I need it for is to insert a CDROM drive or plug in a USB device.

Macs are something you want seen. They're always used as movie props, and very pleasing to the eye. You might not want your beige box PC in plain view, runing your decor, but an iMac might be nice touch to a room.
As for the Apple coverage on /., well I think that is attributable to Apple getting it right (tm). Specifically, you have Unix with a GUI you don't have to dick around with to get working. They have achieved the holy grail of Unix+Usability and that is very attractive to, at least IMO, the people that care about computers, e.g., slashdotters. *shrug*

Looking like OSX isn't the point.
The user experience is what Macs are all about. Running OSX, not just looking like it, and having a wonderfully engineered case.
A PC running any OS it is capable of is like a bitching Camaro kicking ass in the straight-away.
A Mac is like a BMW z4 taking on a winding road.
You either get it or you don't.
A good deal of modders seem to be the computer equivalent of ricers. They generally make a decent looking car uglier while not making the overall system any better.
I think we're better off if the ricers, er.. modders stay away from these systems.
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.
Don't be an ass. Yes, the 9800XT is fast, but:
- It's Build-To-Order only
- It takes up an extra slot
Apple's top-end stock GPU, the 9600XT, is mid-range at this point. The other G5s still use the FX5200, which SUCKS HAIRY GOAT these days and does not belong in Apple's officially designated "Pro" machines.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".

Not to sound like a troll, but modding my dishwasher sounds like a pretty cool idea. Too bad my landlord would kill me :-( That would be sweet to see what's going on when I clean my dishes. Modding is all about being different and having fun when you do it. Since it doesn't hurt anyone, what's the problem? I say if it's fun to do go for it.
This is a sig, there are many like it, but this is mine.
you left out firewire 400/800 card and modem (don't believe that these are on the mobo).
does this support digitial audio i/o?
how is WiFI supported? (can it use a card, or does it have to take up a PCI slot?)
how much to add software equivalent to the following:
iLife (includes iTunes, iPhoto, iMovie, iDVD and GarageBand),
Art Directors Toolkit, EarthLink TotalAccess 2004, GraphicConverter, OmniGraffle, OmniOutliner, QuickBooks for Mac New User Edition, Zinio Reader, Mail, iChat AV, Safari, Sherlock, Address Book, QuickTime, iSync, iCal, DVD Player, Classic environment, Xcode Developer Tools
esp: iMovie, iDVD, GarageBand, QuickBooks
also, if you're using windows that cost should be added in
also, there's the warrantee and online service with the G5.
finally, you left out shipping costs (unless you can get those prices locally)
this narrows the gap somewhat.
I use my Mac for actual work. I'm waiting for the PS3 to buy a console, and I've even put an Ethernet port next to my cable jack for it. Until then, I'm happy to play WarCraft III and UT2K4 in my spare time. They run wonderfully on my Powerbook. Through college I didn't have any trouble finding games to waste lots and lots of my time.
I would rather buy third party RAM than have Apple's profit margin cut. It's that 30% that allows them to put so much into hardware development. Sure, a $1600 G5 would be nice, but if it hurts development and bundled software (iLife is worth a whole lot more than $400), I will be patient.
I'm sure you could pick up a refurb, but that would involve extra effort, and you don't want to actually have to look for products, you just want them to be available.
I'm in the hole of the broadband donut.
