I don't know how much of a speed increase it is vs. the Quad PPC. And like the G5 Quad, it is indeed dual dual-cores (two dual cores), making it four.
Quad-core (1 chip, 4 processors) is something AMD is working on and, if I understand correctly, Intel will be putting something out soon after. heath |
I know it's not actually quad, but 2 dual. Just got in a hurry.
Not going to consider one until they have proper support for my camera. But when they do...tempting. |

Apple is charging roughly 3000 (Canadian) for 7gb (more) ram, and that seems a bit much. One of my local stores sells exactly the same type / quantity of ram (fully buffered, ECC, 667 etc) for about 1600-1800 Canadian. However, they are PC retailers. Is there any difference between PC RAM and Mac RAM in this case? It doesn't look like it, but I'm a Mac Newb. http://www.ncix.com/products/index.p...cture=Kingston http://www.ncix.com/products/index.p...cture=Kingston Would that type of RAM be compatible with the Mac Pro? Thank you, Evan |

Other than that, the pricing on these new systems is very reasonable... I'd order one in an eye-blink if I needed another system right now. Actually, I need a new notebook, but I'm trying to hold off for the 64bit Merom Core 2 Duo CPU to be integrated into the MacBook Pro before I buy... ...Hopefully in the next few weeks. :) |
Hard Drive Bandwidth???
Does the ProMac have enough hard drive bandwidth to edit Uncompressed HD? Can it compete against some of the Medea and Huge Systems products?
It would be amazing if they could get a sustained speed of 250Mb/s. |

How can you raid them? Do you need a raid controller for that or software raid will work as well? |
Is the graphics PCIe or PCIx? Does the new Mac support PCI express at all?

The only problem with the 4 drive raid-0 is the fact that this same raid-0 will also contain the OS, program files and any other garbage you put on there. It is never a good idea to share a media drive with the OS. I really wish Apple would have put in 5 bays. 1 for the OS and garbage and 4 for the raid-0.
With that said I'm sure 8bit HD would work fine but I don't know about 10bit HD. It might work for awhile but you will find on a 4 drive raid-0 that you can only get to about 50% full when the drives slow down past the point where they drop frames. If you add fragmented OS and projects files this may be even worse. I do know that with the Mac you can set the raid-0 where you partition it off based on the faster part of the disk. What you might be able to do is keep the fastest section as one partion just for HD video and use the slowest part for the OS. With that said you will never get 2TB of uncompressed HD storage with the four 500 GB drives. You may only get 1 TB or maybe a little bit more depending on the form of HD you will work with. 8bit YUV 1080i HD actually only uses 120MB/s Which is much lower than the max for 10bit RGB. |
One thing I noticed is that a lot of people think this new Mac Pro is going to be 2x faster than the fastest quad G5. For FCP this isn't really true. If you notice on the Apple website FCP HDV rendering is only 1.4x faster and that is for the 3.0 ghz chips which cost $800.00 more.
The normal $2,500.00 system with the mid level chips is about 1.3 faster in FCP. I really don't see a lot of people rushing out to buy one of these if they already have a quad G5. The other interesting thing is that even the lowest Mac pro should be just as fast if not slightly faster than the quad G5. With that system you can add 2GB of ram and still have a system great for uncompressed HD editing for $2,500.00. You can always capture as photojpeg or DVCPROHD and use just a single drive for now. |

I have always been a PC guy, but decided recently to make the jump to Mac for my next purchase... and I have been waiting and waiting for this box to come out. I'm excited about it.
Good info on the after-market stuff. That will help. |
Can the OS be run off of a firewire 800 drive? If it could then you could leave the full 4 drives for uncompressed HD.
|
I would assume the new Macs can boot and operate off of a USB or Firewire drive. ...The G5 models can.
Although, I would question the logic of doing so... IMO, if you're that serious about HDD bandwidth, install a fiber channel card and buy an external fiber-connected RAID. Hopefully Apple will update their XServe RAID products soon. It's been a whole year since they last updated the product line and its pricing. And sadly, the pricing is very out-of date, costing more than double the competition these days. However, I picked up a refurb Xserve RAID on eBay with full AppleCare support for a song. I still don't know how I pulled it off but I paid less than 1/4 Apples MSRP. |
