the obvious question on PM

what is the performance difference between a dual 2ghz and a dual core single 2ghz ?

Anybody knows, guess ?
I already read somewhere someone saying performance is superior with a dula processor vs a single dual core, but that the overall performance on the machine may be similar or better as a result of other improvement (mainly RAm speed).
 
Detail shots New G5

This morning we received our shipment of New PowerMac G5s. I took some pictures of the interesting changes I had noticed right away. Look at the power plug change. The antenna is now a bar on the back instead of removable pegs. The PCI-e is 4x and 8x slots, labeled on the motherboard. The new tower also has a slot for a combo Airport Extreme card with Bluetooth and not the standard APX slot.

my question is: why does MS get 3-core 3.2Ghz from IBM now, and Apple only 2-core 2.5Ghz?

Or are we talking about different processors?

Yes you are talking about decently different processors.

The PPC 970 (/FX, /MP) in the Power Macs are a general purpose CPUs with the ability to have a large number of instructions in flight and executed out of order.

The PPC cores used by Xbox are simpler cores with minimal in flight instructions and in order execution.
 
I am puzzled.
Apple mentioned that you can buy 4 graphics cards for the current PM g5.
But when your order any of the new PM machines it just give option for 2 graphic cards
NVIDIA GeForce 6600 256MB SDRAM.
QUADRO FX 4500 512MB SDRAM

Why is that?

I think the real secret to Apple's success are ;) the BLUE motherboards. ;)

Anyway, does the Powerbook memory spec of PC2-4200 DDR help any, performance wise?

For some reason the Apple store isn't listing all of the options at this time. The tech spec page for the PowerMac lists the following options.

NVIDIA GeForce 6600 LE with 128MB of GDDR SDRAM
NVIDIA GeForce 6600 with 256MB of GDDR SDRAM
NVIDIA GeForce 7800 GT with 256MB of GDDR3 SDRAM
NVIDIA Quadro FX 4500 with 512MB of GDDR3 SDRAM (occupies 16-lane PCI Express slot and adjacent four-lane PCI Express slot)

AidenShaw will probably chime in on this subject. The moment he does, I'm outta here. :p
 
Pci

Is PCIe backward compatible with PCI/PCI-X? All of the existing pro audio cards are PCI! :confused:

I never complained that Apple doesn't update quickly enough, I just stated that this new quad, whilst great for Apple and for the future of the Power Mac comes only after having mine for 4 months which makes me feel sick!!! I mean you could have bought a dual 2.7 ghz yesterday and now this! Then you'd be sick too. Doesn't seem fair really...to reiterate, if Apple, or some other reputable firm offered a part exchange system I'd use it!
;)

well, what do you expect when you buy a machine that has not been updated for a LONG time. If you ordered a top of the line G5 when it was introduced, then a week later they dropped a better one, ok. But your argument is like buying a 2005 model car at the end of the year when the 06 models are comming in, then bitching that you got an old car. You waited to pull the trigger and get your G5... and in doing so, made the window from your purchase to the new updates a short one, and now you are butthurt. Buy this new G5, and you wont get outdated for a long time.

and it kills me how all these people are ready to throw their machines away because a new one is out. Must be nice. I am one of the few users that actually utilizes mass computing power, and yet my old G5 tower still gets the job done. I do LOTS of HD video work, pro photowork, animations etc.... and my old machine still gets the job done. When i get 20g's to drop on a new machine, i will configure a max'd out G5, but till then I feel ok with what i have.

It cracks me up when people constanly upgrade to crazy fast machines, so they can surf the web, chat, email and burn CD's with..... There is a VERY small market for such a powerful machine. Im willing to bet that maybe 5% of mac users would benefit. Otherwise, you are all just throwing away your money.

Nope. They have different signaling and connector types. Of course you likely will be able to find PCIe to PCI/PCI-X breakout chassis in the not so distant future.

Oh also note Apple is still selling a Power Mac with PCI-X if you need such a system still.

Goddammit I'm so pissed right now...saved up for months to buy a Dual 2.7 Ghz Power Mac back in April (although it took a whole month to arrive but that's another story) thinking it would last...and now this a few months later. Apple have screwed me and many others again....70% performance advantage over yesterdays "top of the line" mac!!! But still we buy their products! If you're listening Jobs, offer to buy mine back and give me a mega discount on a quad, that will make me happy. :mad: :eek: :mad: :eek: :p

Why on earth would ANYBODY think that their top of the line computer would not be superceded in a matter of months? If it's the first computer you've ever purchased, I could maybe understand that. But, unless you've been living under a VERY BIG rock, you have to realize that times change and computers get faster. Well, maybe unless you're looking at Powerbooks :D
 
that's why I waited so long. The 2.7 gig were nice but I always felt that something better was around the corner. My patience paid off. Better machines and cheaper displays.
Never buy a computer after it's been introduce 6 months later. you can always regret it. plus make sure you check the rumor sites about any possible upcoming upgrade. that makes a safe bet IMHO.

Aww... My single 1.8GHz G5 is getting old.. And what happened to ATI graphics cards? I need ATI.
It's a pup compared to my 350 MHz Blue and White G3. :p

Apple still is being cheap when it comes to RAM. 512 for the top end machine that is sad. They should be shipping 1gb standard if they are going to charge $3200. Other then that I am glad to see more graphics card options and faster slots.

And $12000 to go to 16GB of RAM? That's $.75/megabyte, which sounds like a lot to me. I've not bought DDR2 RAM before, but I see it listed around $.20/megabyte other places.

I know Apple likes fat margins on BTO options, but come on, thats 3x the market price!

Apple finally did it the cemented the Power Mac as one of the worlds high end UNIX workstations. Now where are the high end UNIX workstation apps that require a Quadro FX?
Alias Maya... at least thats what I'm usin it for anyways.
 
The Quad is the only thing I am impressed with, the PowerBook update wasn't even mediocre. The PowerMac also looks smaller, is the case smaller?

The way Safari crawls sometime it makes me wish I had four cores....besides I think what you mean is there is a small market for that power *at that price point*. Obviously if it cost half what it actually costs, people would buy like crazy. People will find new ways to use the extra space and power.

By the way, if anybody gets a 2x30" setup, can you please post the pictures? And dress up like Dr. Evil too.

That is a defect in Safari that in my testing appears related to use of some aspects of Java Script. It causes Safari to stall the main thread... having more cores wont really help with this at all. Hope for an updated Safari to address this issue.
