3.0 GHz an 80w or 120w??

3.2GHz Model Is 150 Watts Each

newtech said:
Once again, look at the facts...

1. 2.8 and 3.0 share a motherboard unique from the 3.2

2. E5472 (3.0 ) is 80 Watts TDP same as E5462 ( 2.8 )

3. X5472 (3.0 ) is 120 Watts TDP same as X5482 ( 3.2 )

4. 120 Watt X5482 ( 3.2 ) REQUIRES uprated cooling vs. 2.8/3.0

5. Apple tends to get the "pick of the litter" from intel in terms of faster and lower power.

6. Seeing X5472 on the retail market looks like Apple passed on them else they woud be more scarce like X5482.

7. Apple seems committed to being more green/energy efficient so E5472 would fit better to such leanings.

This Chart says the 3.2GHz model X5482 is 150 watts not 120 watts. Did that change since November?

I bought the 3.2GHz model 'cause I wanted to go ALL THE WAY. Arrives Tuesday February 5 - Super Duper Spectacular Extra Crispy Tuesday! :p

I guess I took the NON-Green path. At the time I didn't know it. All I knew is I wanted MAXIMUM SPEED no matter what it cost. I guess that makes me an energy HOG. Oh well. I trusted Apple to not let me do that.
 
150 Watts TDP for X5482 was based on the pre-release stepping. The newer stepping for X5482 is alleged to be 120 Watts TDP same as X5472. The newer stepping allowed for an E5472 at 80 Watts TDP.

Note availability for X5482 and E5472 were put at between Now ( 11/12/07 ) and 45 days ( 12/27/07 ) and that the new mac pro was announced 1/8/08 for immediate ship. Oddly coincidental, would you say?

I am wondering if the first batches of 3.0 got X5472 and at some near point they will get E5472.

Precisely what I think. Time will tell.

I've decided to get the 2.8 anyway since it's not worth the $762 to me. (TimeWarner Employee discount).
 
I have a 3.0 MacPro

I have one - had it for 2 weeks. How do I tell you whether I have the 80 or 120W?

Hahaha. Wow. Just about everything you said here is wrong.

install windows in bootcamp then install CPU-Z.exe. It will tell you.

OR you could just install the istat pro widget and check your idle cpu temps. If they are over 40c then you have the 120w. Mine idle between 28c and 35c. 28c if it just sits there for a few hrs with nothing happening.

Finally! By the way, Thank you for participating in this... You are one of the few with a 3. Everyone else seemed to get theirs with an 8800GT (it seems). We look forward to hearing what you give us (although I'm not sure what the accurate way to tell is).

Are these the only two methods? There isn't a Mac Application that tells you directly? (I really am clueless, i just wondered if there isn't a way to be 100% certain... maybe by looking at the board directly? Not sure where to look tho). I just want this debate to be concluded without any speculation, t'is all.
 
Actual wattage use

I'll try not to go too much off topic here, but Barefeats has done a test, showing peak wattage use for the 8-core 3.2GHz and the 4-core 2.8GHz, and compared them to previous Mac Pros as well as the iMac 2.8GHz. Interesting numbers (scroll down the page to the title "Go green if your needs are simple").
 
OK - well, my CPU runs at about 30C or lower most of the time. I will try downloading the .exe file on my bootcamped windows at work tomorrow... So, seems like 80 to me thus far....
 
80w E5472

Nobody seems to have a definitive answer.

I am going to guess that it is the 80w E5472.
Don't kill me now because I am basing my answer on a totally unscientific method.
I googled "Mac Pro" E5472 and received 1110 hits.
I googled "Mac Pro" X5472 and received 801 hits.

And the winner is the E5472.

It´s funny to see those 1911 hits - but none of them can really answer the question. What the hell are they all about ????????

Hey man, what's the word? Also, if you could, be sure to try what diamond.g suggested:

Intel has an app that will display all the CPUID stored stuff on their chips. It is called MacCPUID.

And the answer is...

Well, I have the definitive answer on what it is. I downloaded MacCPUID.app, screenshot below. Could someone *PLEASE* explain the difference to me - why should we care, practically, whether it is running at 80 or 120?

The answer is... 120W

YOU ARE THE MAN !!!!

Thanks ;-)


120W means: The system needs more power - and might be a little bit louder than the "green"-version of the 3.0 GHz Mac (E5472) that only requires 80W ... if it exists at all ;-)

great work, you've helped me a great deal in making up my mind on what processor to get!

2.8!

Wonderful... thank you, thank you.

That makes me glad I got the 2.8 now. Not that I wouldn't mind having the 3.0 or the 3.2, but I chose the 2.8 on other reasons and glad to hear its less energy intense as the other models.

Anyone else see frequency is reported incorrectly.

2,999,999 (Hz) = ~3 MHz

should be

2,999,999 (kHz) = ~3 GHz

-OR-

2,999,999,999 (Hz) = ~3 GHz
