Apple today announced the all-new Mac Pro will be available to order starting Thursday, December 19. Redesigned from the inside out, the all-new Mac Pro features the latest Intel Xeon processors, dual workstation-class GPUs, PCIe-based flash storage and ultra-fast ECC memory.

This thing is so damn awesome. I don't need it, but I still want one.

the problem with those gpus is that they use consumer-chips


That's not really a problem. It's not like the Pro designs were simply replaced by consumer chips, and that's-that.

When chips were fixed-function, it made sense to optimize a piece of silicon for gaming or for workstations. Since chips are so general-purpose now, there's really no point in doing the optimizing on the chip - instead, it's done on the driver.

Some workstation-only features are now part of the architecture as a whole, and are exposed via driver + extra connectors - features like genlock/framelock, ECC memory, and stereoscopic. These are workstation features, and the silicon is also present on consumer chips.

One could also say consumer products use workstation chips. 10-15 years ago, both this and the converse would have been meant something, but it hasn't been true in a while.

So, the real question is, are the drivers on the new Mac Pro actual FireGL drivers? FireGL drivers are a different beast from consumer drivers. They are optimized heavily for geometry over texturing, tend to handle basic untextured views better, and handle wireframe views better. At the same time, gaming performance isn't as good as the consumer counterparts.

Other features exist in workstation drivers, like being able to partially render only part of a window (Say, when a viewport is partially obscured by another window), multiple clipping planes and slices, etc.

Finally, validation occurs. Apps are certified to run on a specific driver level, and driver development happens with close communication with ISVs. Accuracy of the rendered image is far more important than performance.

These things are what makes a FirePro a FirePro. Is Apple doing these things?

I left out a big feature of workstation cards, and that is 10-bits-per-channel color.

Now that the MacPro is available to order, they've got a Sharp 4K screen for sale. The screen supports 10-bits-per-channel, but they aren't advertising it as a feature on the Apple site, because MacOS X doesn't support 10-bits-per-channel. This is a limitation of the OS. Mac compatible NVidia Quadro cards can support 10-bit color channels under Windows but not OSX.

I'm surprised Apple hasn't added this along with their Retina displays. Sharpness is nice, but added color fidelity is just as good.

Yeah... That is kind of what I was getting at with my questions. Lets say the D700 really was a w9000, i.e. the hardware is 100% the same and the w9000 drivers would actually work on Windows in bootcamp...

An entry level Mac Pro outfitted with 2 D700s costs $3999. At that price, you are saving about $2000 off the costs of buying the 2 GPUs all by themselves - its like getting a 33% discount on the GPUs and hey, we'll even through in a free workstation as a bonus...

I find it highly unlikely AMD would go along with this, as it would undercut their own pricing severely. So I suspect it won't be a functional replacement for a w9000. Maybe it is virtually the same hardware, but there is no way it is going to work the same way in bootcamp as a real w9000...

In short I don't think any of the things that traditionally make a FirePro card carry it's pricing premium really apply to the Mac Pro. Its probably going to be optimized for use with Apple's software stack (Arpeture, Final Cut, etc.) and that's it. Its a 7970 with a boatload of VRAM on it, nothing more. It kind of makes sense too because most of the apps you care about having certified support for don't exist on OSX.

Its two roughly $500 GPUs, which turns the deal of the century into "meh"...
