Apple Releases New PowerMacs

My guess is that one reason for abandoning liquid cooling is the ability of water to go through very tight spaces within the engine, expanding its cooling reach. You'd need that for larger engines. Generally, air cooled engines were very small, as I recall; I don't remember anything with more than four cylinders being air cooled, though I could be wrong.

Didn't the Corvair have 6 cylinders and air cooling.

Not to mention, of course, the 10 and 12 cylinder aircraft engines that were air cooled.
 
Sonnet Technical Support Says Yes. Why Didn't You Call Them?

ClarryUK said:
I currently have a Blue & White PowerMac G3, for which I bought a Sonnet Tempo ATA 100 PCI card to attach a second hard drive.

This works fine but I am about to buy a G5, which can only accept Serial ATA drives, and has PCI-X slots.

So, I am wondering if I can still use my existing hard drive that’s in my G3, with the Sonnet Tempo ATA 100 card in the G5.

I’m not sure about voltage and all the rest of it, so I don’t know if:

a) the Sonnet Tempo ATA100 card can be used in a G5 with PCI-X slots, and

b) an ordinary ATA drive (IBM Deskstar 60GB) will work in a Mac that only takes Serial ATA drives, if connected via the Sonnet Tempo ATA 100 card.

Can anyone shed some light on this? I don't wanna fry the card, G5 or hard drive trying it out!

Thanks 😕

Sonnet Technical Support Says Yes. Why Didn't You Call Them? 949.472.2772

No drivers are needed and the card is 3.3 volts. So they say they have not tested it themselves but see no reason why it would not work. Good Luck!

I didn't call them as I didn't want to make a long-distance call from UK to USA!

I emailed them instead and they replied that while the card probably will work, they haven't tested it and anyway, why would I want to put an old PATA drive in my shiny new G5?!

I don't particularly - it just seemed a waste to bin a perfectly good 60Gb hard drive.

😱
 
A silly question?

I know this is probably a really stupid question, but...

When a G5 is "Dual 2Ghz", does that mean it has 2 chips, each of 2Ghz or does it mean it has 2 chips each of 1Ghz that add up to make 2Ghz?

No sarcy replies please!

Thanks 😱
 
Two 2 GHz G5 Processors - Effective total 3.6 GHz.

Wow! You really are a newbie. It has TWO 2 GHz G5 Processors that work in parallel with the system and many applications. Total effective power is just short of 4 GHz because of about 10% overhead - about 3.6 GHz. The new dual 2.5 has an effective power of about 4.5 GHz.

it has 2 2ghz chips. I had a really hard time laying off the sarcasm on this answer.

Yes... thank you! I'm not a newbie at all, but am perhaps not as techy as some of you!

I thought Dual 2Ghz meant 2 x 2Ghz chips but remember reading on this or another forum some time that it means 2x1Ghz chips = Dual 2Ghz so just wanted to check for sure!

Nobody can answer the question of whether all the "new" G5's run on the new 90nm chips or the old 130 can they?!! 😛

I have yet to see a definitive answer to that ... though there are reports that the Rev. B 1.8 and 2.0 GHz G5s are in Apple stores now.

I'm waiting for somebody to get a serial number off the CPU and find out whether its an old 970 or a new 970FX chip. (hint, hint)

Well, my new Dual 2Ghz is due to arrive in the next 2 or 3 days so if I can get to see the chip, I'll tell you!! 😀

Hey, thanks, Clarry.

But, er ... you don't have to answer this if you don't want to ... but you ordered a "dual 2.0 GHz" without being sure whether it was 2 x 1 Ghz or 2 x 2 Ghz? 😕
 
I Just CANCELLED Pulling The Trigger On The Refurbished D2 G5 for $1999 + AE for $79

I Just Pulled The Trigger On The Refurbished D2 G5 for $1999 Plus Airport Extreme for $79. I decided that 50% more money for 25% more power is not worth the difference. I hope I don't get a chirper. Didn't buy AppleCare yet. There were single 1.6 G5's for $1299 and dual 1.8 G5's for $1799. But the dual 1.8 comes with a nVidea video card that is not as good as the ATI 9600 Pro that's in the dual 2. Those are all gone already. You think I should have ordered the 90 nm Dual 2? At the educational rate it is only $186.25 more.

Well I wanted the dual 2.5 really bad. But money is a factor so I am going to have to "survive" with what was the top of the line a week ago. It still meets Motion minimum recommendations. Now I can spend another $450 on a 2 GB Expansion (2 1GB sticks) - or less if I go with 4 - 512MB sticks.

So I am now officially among the obsolete dual 2 GB 130 nm 970 refugees.

NOW I CANCELLED IT. I realized afterwards that there is only $186 difference between the old one and the new one educational with 128 MB RAM and a COMBO drive and 90 nm processors (I hope). My bad.
 
whatever!!

Hehe, no, I was 99% sure it was 2x2Ghz but, as I said, someone (obviously even less clued up than me) on some forum somewhere recently said that it wasn't so I was just checking!

Either way, it's still the middle of the 3 new G5's so whether it's 2x1Ghz or 2x2Ghz is a bit beyond my control and I want to replace my now 5 year old G3!!

Ok? 😱

OK. Just be sure to use a screwdriver, not a crowbar, when you pry the cover off the mobo. And don't forget your grounding strap! 😛

So let me get this right.. you paid $186 more, to get less? No DVD burner, no 9600, etc.??
 
Village Idiot said:
This revision is totally sh*te. Not because of the speeds, but the lack of other features. Why only one FW 800 port? Same Hard Drive space, Last years graphics cards. What about a dual layer DVD burner option? I want this for HD video editing and I bet if I fork out for this now, the new 3Ghz with slick graphics card for the 30" screen will be out in September. I can't win. Think I may as well hold off until a real upgrade.

Any other editors feel the same? 😡

I don't think its ****, but i would have like more... this update leaves something to be desired. Oh well, i will still end up with a dual 2.5 and sinc eits on the company tab I wont. 🙂

No. The DVD burner is a Pioneer DVR-107 which I can buy with the $90 saved by ordering the Combo which nets a free Apple certified Combo. That's with the 9600XT and AE card.

Really??? so the Dual 2.0 with AE and 9600XT comes to only $186 more than the refurbished model? If this is the case, nice deal, I got a refurb instead of a new dual 2.0 because I couldn't afford the extra $400.

It ain't 3.0, but it's still sweet.

Now to bear the brunt of all the "APPLE DIDNT GET 3.0 OMG LUZERZ LOLBBQ!!!1!one" whiners. IBM had trouble at 90nm, not too surprising, Intel did (and still does) as well. I was surprised they made that promise last year; ramping 1.0GHz in a year is VERY aggressive.

Check for 3 GHZ @WWDC 🙂
 
Boo, Apple installed the Nvidia card in the dual 2GHz 🙁 Why could they have left the ATI card? 😕 It had slightly better frame rates.
 
Do I need a G5 to edit DV?

Do I need a G5 to cut DV? Isn't that overkill? Isn't a Dual 2.0 for cutting uncompressed hidef and the like?

Wasn't the corvair "unsafe at any speed"??? 🙂
Click to expand...

Nope. I used to own one.

It was never clear why Nader picked on the Corvair since many cars of the same era had the same problem. Essentially, there was a tendency to go from understeer to oversteer (or vice versa, I can't remember) at high speed when making a turn. If you weren't ready for it, you could lose control.

The effect was worse on the Corvair because it was fairly light, moderate power, and rear engine - so it was easy for a person to get in over their head. Once you were used to the car's handling, though, there was no issue.

In any event, the later models (66-69, IIRC) had the 'problem' fixed - but it was too late. Nader had already effectively killed the car. That was a shame-the Corvair was a fun, reasonably priced car.
