Much of that performance gain is almost certainly GPU related, not CPU related.
The Quad-Core Mac Pro has twice as many cores as the 2010 MBPs, which are Dual-Core, so that would only result in 2 times performance gain.
I suspect that you would probably have achieved a similar result with a 27-inch mid 2011 iMac upgraded to 3.4GHz Intel Quad-Core i7 and 2GB 6970M GPU.
New poll over at french site macgeneration
"What will be your next computer".
6% vote Mac Pro, again more than Mac Mini !

We don't even know if there will be a 2012 Mac Pro. If there is I would say thunderbolt will be on it.
More voted for getting a PC than mac pro should tell you something. Plus beating the mini isn't a big deal, worthless machine not fit to be a desktop yet can't be used as a portable - utterly useless.
Good for a TV if you watch movies in mkv and avi (movie server) Also good for audiophile firewire media server. A little Amarra player and a Benchmark DAC (or whatever) and you have a great little hi-fi.
But how many are in the market for a Pro workstation compared to a consumer computer? I'm guessing not many.
Guys, it's way simpler than that. Xcode automatically parallelizes building your different classes between cores.
On a 2 core machine, XCode compiles two classes at once. On an 8 core machine, you get 8 at once. Because a single target can have hundreds (or thousands) of classes (and you may have more than one target), a Mac Pro can easily rip through Xcode projects.
So yes, the compiler is multithreaded. But every class compile is single threaded, it just can do more than one class compile at a time with more cores.
Dependencies don't matter until linking time at the end when everything is compiled, so the compiler can usually ignore dependencies entirely.
This is also why the Mac Pro is a great development machine. If you have a 12 core, you will get 3x the performance of what any iMac can do.
Thanks for your contributions!
Whatever the explanation, I just timed it informally. Build from cleaned project (of course everyone's would be different):
40 sec on MBP 2010 i7 2-core 2.66GHz
<2 sec on MP 2009 Xeon 4-core 2.66GHz
so, a factor of twenty for me just doubling the number of cores (I doubt that XCode is using the 5870, but...).

True, more and more pros have moved onto BOXX, Dell, HP, DIY Newegg and hundreds of other boutique builder workstations configured anyway they want with any possible option. They know that updates will be available sooner without all the super secrecy of Cupertino's version of the North Korean magic kingdom.
I don't think new Mac Pros being available have anything to do with them being announced. Apple could announce there will be new Mac Pros today and it changes nothing if you still can't actually get one.
So Apple can be a North Korean magic kingdom all they want for I care up until they day they release new ones. It's the actual releasing of new ones I care about.
There's way too much angst in this forum about Apple showing, instead of more well directed angst about Apple doing.
Well, in other words, to say the percentages reflect the Mac Pro users moving to PC workstations is very misleading. It does not state as such and does not reflect the consumer Mac's users moving to consumer PC's which are probably the vast majority of that 8%.
If Intel has bungled the release of the Xeon E5's so far .... coming Q3 '11 , coming Q4 '11 .... coming Q1 '12 .... well announced but not quite up to volume to satisfy all contracts yet .....
Why would they announce early?
Nvidia and AMD haven't done too much better on the GPU side. TSMC was going be cranking those out in Q3-Q4 '11 and only extremely minor subsets of those product lines were coming out of the fabs by Jan '12.
Given these crews' track record over the last 12 months I wouldn't announce anything until had a backlog of parts in the factory and had started to crank them out in volume to a get to a release point.
Notice even HP is only system vendor to go out there on the limb and "pre-announce". I think everyone else is in the "fool me once .... fool me twice ..." camp. Apple typically plays things conservatively enough to be in the firmly in that camp by now. If this drags on until very close to the Ivy Bridge release point (end of April ), HP is going to look goofy with the "just wait till (implicitly early) April ".
HP now list them to order.

Not clear when you might actually get one though!
NAB is coming soon. Most vendors including Apple would no doubt like to have their workstations shipping by then.

NAB is my choice for some info. Updated or deprecated. Either one. Don't care. I have 3 more years on the hex before I even start looking. I haven't had purchase frustration in a while. I do feel everyones pain though. Throwing away money on older tech when "maybe, possibly, should be" is around the corner.
