Hi,
I think one of the biggest negative factors will be their price. But Mac Pros were always expensive, and cost more than similar spec'd PCs.
This is not true is you compare using the exact same processor !
I did a study a few years ago ; the high end Macpro was a few euro less than the Dell servers with the same processors !
Cyril is right:
in 2008 a dual Processor Mac Pro was not so that much expensive compared to the others.
The easy reason was that they bought all the available XEON processors, not very fair....
... killing computer for a MIR configuration.And if VSL uses the power of the graphic cards !
i asked this question years ago already und the answer was as simple as shattering:
the available grafic-memory is not large enough to have the impulses permanently loaded in (grafic card) RAM, which is required for fast calculation of the audio to output. using the GPU power just for calculations would result in a bottleneck on the bus (constant loading/unloading of impulse data) ...

That may have been true years ago when you asked that question.
The VRAM in the new Mac Pro can be up to 6GB. The largest venue for IRs in MIR Pro is 1.32GB. So, please ask this question again.

well, besides you would need at least some memory for the display(s) 😉 it is not as simple.
you also have to get the sample data (preload buffer) into RAM to have something to calculate on and not all GPU processing threads can access all memory, especially not simultaneously.
get an idea reading this article(s).
GPU processing is great for calculations which can be easily fragmented into little portions of jobs, it is not as efficient for multi impulse response reverbiation when the *whole room* is applied to every single instrument.

I'm not going to join the discussion, but just to avoid misunderstandings: The RAM used by MIR's Venues is not only dependant on the number and length of the original impulse responses (which is reflected by the raw size of a RoomPack), but mostly on the number of Icons used on a virtual stage. Each Icon triggers the pre-rendering of a unique set of impulse responses, depending on its position, rotation, stereo width, the chosen Instrument Profile, the global Reverb Time trim factor, and of course the selected Output Format (... multi-channel formats will need more RAM than stereo, for example).
This will happen again for each and every change applied to any Icon.
Kind regards,
Not really interested in debating this either. I just think it prudent to revisit the question of moving certain functions to the GPU given what cm said the reason it hasn't been possible before. But I think you guys already know that. I'll trust that you do the right thing whatever that turns out to be.

I like it, dustbin , the concept of a unified fan that large will keep it cool and quiet. Lots of power under the hood and lots of ram, excellent, Xeon is the only way to go.
So how much? And i hate when Apple says, " starts at"..just give us a price fro the whole enchilada.
Thanks for posting
Cheers, JRM

Everyone try to remember that these machines going back to early Mac Pros were not built for musicians. Their prime target is the graphics boys and girls. Musicians come way down the list.
Yes, this is Very True !
Apple was more into catering for the Pro- Graphics, video, Post Video, ..than for Pro Audio-Production community.
Also look how much more attention FCPX gets compared to Logic Pro !
Their history proves this.
Apple has released the new specs. Their audio blurb (which predictably follows the blurbs on video editing, 3-d modeling and animation, and photography):
More power across the board.The new Mac Pro delivers up to 12 processing cores (up to 24 virtual cores) and up to 60GB/s memory bandwidth — twice the bandwidth of the previous-generation model. Now you can work with even more tracks of virtual instruments, plug-ins, and effects than previously possible. And the ultrafast PCIe-based flash storage loads all those instruments, samples, and loops almost instantly.
Connect to next-generation I/O technologies.
Six Thunderbolt 2 ports and four USB 3 ports redefine the meaning of expansion. Connect up to 36 best-in-class audio I/O devices from Avid, Apogee, M-Audio, MOTU, Universal Audio, and more. And with a PCI expansion chassis connected via Thunderbolt, you can work with the DSP and audio I/O PCI Express cards you already have.

for those among you interested in benchmarks and such:

in a nutshell:
- for single-threaded applications: a bad idea (eg. iTunes)
- for multi-threaded application: a very good idea (eg. MIR)
- for your pocket: there are better ideas ;-)

The Mac Pro is well designed and a nice idea. That is all.
A powerful Haswell Win PC with 64 GB RAM, and 3 x (built in)1TB SSDs is cheaper and especially for a VSL user much more effektive. I think it will not be a big success in the Music-Pro area.
You make me laught if you want to compare two system you must use the same processors.
Processors price is dictated by Intel !
PC and MAC are using the same processors, when you pay a XEON processor more than 2000 $ you cannot put it in a computer that you sell for 1000 $ !
You cannot have a dual processor computer with the Intel processors I serie (I5, I7......)
Also you don't need 3 TB for VSL, 1 TB is enought, also it is better to by 4 x 256 GB SSD and to put them in a Raid 0, you will multiply bandwith by 2 or 3
