Mac Pro Developer Notes

[Sun Baked]

This should answer some questions that keep coming up in other threads...

What does it answer? The Mac Pro support site isn't up and one of the documents points to the G5.

Gives specifics on the architecture of the machine and specifics not available under the applestore links ... just have to follow the links.

can't find the actual wattage of the PCI Express slots anywhere else

When populating the four PCI Express slots, you need to conform to the following total wattage rules:

* Slots one and two (not including aux power), max slot power per slot: 75 W
* Slots three and four (not including aux power), max slot power per slot: 40 W
* All four slots (not including aux power), max total power: 200 W
* Max aux power per connector: 75 W
* Max aux power for both connectors: 150 W
* Max total PCI Express power (slot power and aux connector power): 300 W

Somethings vastly important to adding other graphics cards.

A little more digging there helped me. I knew the developer notes would give us more info then the store. Any word on the power supply wattage?

Not that I doubted your link was worthwhile.

PCI Express Power Constraints

All four PCI Express slots conform to the PCI Express Spec Common Electromechanical Specification 1.1. Slots one and two also conform to the PCI Express x16 150W-ATX Specification 1.0 for power through the two auxiliary power connectors for 12 V at 6.25 A max.

For information on PCI Express specifications and design guides, refer to PCI-SIG.

Each PCI Express slot provides 3.3 V and 12 V power rails. On the 3.3 V rail, each slot may use a maximum of 10 W. On the 12 V rail, each slot may use a maximum of 65 W (not including auxillary power), subject to the total wattage rules listed below.

When populating the four PCI Express slots, you need to conform to the following total wattage rules:

* Slots one and two (not including aux power), max slot power per slot: 75 W
* Slots three and four (not including aux power), max slot power per slot: 40 W
* All four slots (not including aux power), max total power: 200 W
* Max aux power per connector: 75 W
* Max aux power for both connectors: 150 W
* Max total PCI Express power (slot power and aux connector power): 300 W

It seems to cover system architecture... which for a non-shipping piece of hardware is a very good starting point.


Thanks for posting this Sun Baked!

I dug the PCI Express slot info out in the previous post ... adding to the graphics card usage info

Nvidia GeForce 7300 GT, single-link		256 MB (GDDR2)	32 W

ATI Radeon X1900 XT, double-wide 		512 MB (GDDR3)	132 W

Nvidia Quadro FX 4500, double-wide 		512 MB (GDDR3)	110 W

Well, I was going to post that too in my previous post. Any word on third party PC video cards? Not that the 7300GT is enough for me for at least a year or two. I'm more interested in raw CPU power.

Mac Pro Computers (August 2006)

The Mac Pro computers announced in August 2006, based on the Dual-Core Intel Xeon processor, have an optional, internal AirPort Extreme wireless LAN module. The AirPort Extreme module connects through a one-lane PCI Express bus to the South Bridge IC. The Mac Pro has built-in antennas. AirPort Extreme is available as a fully-integrated configure-to-order option or as an Apple Authorized Service Provider kit, which can be installed by an Apple retail store or an Apple Authorized Service Provider.

Note: The Mac Pro contains 802.11b, 802.11g, and 802.11a radios; however, Apple supports only 802.11b and 802.11g.

I think we have one of these on campus so I can get my Mac Pro this week instead of waiting for it.

Umm arent the Quad Core Xeon's coming spring 2007, personally I will be waiting for those and a Leapoard computer to ship all in one.
