Wow, the design of this new Mac Pro is amazing. I'm going to have to think about its functional expansion though...
But the other wow is the seemingly clueless posters here. I never imagined so many supposed Apple followers (and several WinPC trolls) who are completely ignorant of technology.
1. Go look at Apple's web site and learn something before posting.
2. Whether you like the shape or not, the engineering/design is undeniably phenomenal.
3. Can you say aluminum, not plastic?
4. It appears to have 1 CPU (future 12 core?), 2 discrete GPUs, 4 RAM slots, and 1 SSD slot.
5. RAM is "limited" presumably to 128GB, maybe 256GB. DDR3 is what Xeon CPUs use. GDDR5 is for GPUs (6GB).
6. Storage (SSD) will be "limited" presumably to 1TB, maybe 2TB with new flash chips.
7. The RAM and Storage (SSD) speeds are off the charts!! 60GB/s & 1.2GB/s holy cow!!!
8. Count them - 6 Thunderbolt ports. That's 120Gb/s of total bandwidth.
9. Count them - 3 simultaneous 4k displays. Wow.
I don't think you people quite understand how much power they've squeezed into this little cylinder. The former Mac Pro tower, maxed out with the highest end PCIe cards available doesn't come close to the processing capability of this new system.
Now for you yahoos that don't understand the significance of 4k video, let me try to help you. It is 4 times the resolution of HD, or about 8.3 million pixels per screen (vs 2 million). You don't just plug in a 4k screen like a regular monitor. VGA can't do it (ROFL), nor DVI. HDMI will barely support one 4k screen.
Some PC rigs hack together 2 DVI or 2 DisplayPort connections to a single screen to reach 4k - that's 1 screen. Nvidia's highest end GeForce card supports only ONE 4k display over HDMI. In PC land you would need 3 top-end, double-wide graphics cards attached to a motherboard with 3 PCIe x16 slots to do what this new Mac Pro will do with a simple Thunderbolt cable. No, PCs aren't running 4k all over the place without end. What a laughable statement... I know of no other system that can support three 4k displays.
The convenience of internal expansion capacity is arguable. Some people like all the stuff in one box. Other people don't care about that. It's a personal preference.
Do you need multiple terabytes of hard disk storage? You can easily add an external disk array to this new Mac Pro in capacities that will far exceed what was possible internally with the old Mac Pro. And since you can do it over Thunderbolt, a properly designed Thunderbolt disk array will give you far, far better performance than the old Mac Pro internal SATA connected drives.
How long do you think it will take for 3rd parties to make an external disk array that can hold, say 8 hard drives, and put it into a 6" black cylinder than will fit perfectly under the new Mac Pro? I bet you'll see one before the Mac Pro even ships.
You photo/video guys - what PCIe cards do you have that won't work in an external 20Gb/s (PCIe x8) expansion chassis? The only cards that require x16 slots are high end GPU cards, which won't be necessary considering the internal workstation level graphics on this new Mac Pro. Heck, half the stuff you're relying on PCIe cards for now can be done in software on this new system (once the software is written to do so).
I could go on and on, but this post is already too long as it is. There are so many technical details to explain (like why a Thunderbolt connected disk array will perform better than internal hard drives) that I can't do it here, and you people probably wouldn't read it all anyway, if you've even read this far.
