xeon sandy bridge only come in 6-core or 4-core chips.
http://en.wikipedia.org/wiki/LGA_2011
you could be mixing up threads with cores. ie, the 8-core (2 x-4core) would have 16 threads total.

The most important Pro app for this machine is Xcode. Xcode does a GREAT job of using multiple cores and all those iOS devs who have big projects will be eager to get this grade of Mac OS X machine.

LOL. Are you saying that Apple will have to keep the Mac Pro around if for no other reason than to compile applications for the Itoys?

Any particular reason you have taken to referring to them as toys? My iPhone isn't a toy any more than my Razr was: rather, it's an essential communication device. And I am now able to run my standard four or five day business trips solely from my iPad: its email/office/browsing capabilities are fine, and its multimedia and gaming chops are great for once the work day is over. Hardly a toy.
Heck, I completely understand why some people need the power of a Mac Pro, but it irks me when they refer to what they do as "real" work, thereby suggesting that mine isn't. My clients think it's pretty real, and they are certainly willing to pay real money.

you're right. i was looking at a wiki page with only a selection of the xeons listed and not the entire lineup.
that list certainly looks more formidable than the 1600's i was looking at. so, potentially, a $6000 mac pro could have 16-cores too. nice!

Slimer Mid tower design MP + (Cost saving) SB Processor + Universal (not just Mac only variants) AMD 5xxx, 6xxx Graphics Card support (6990 excluded for obvious reasons), starting at the 1499.99 = Legit Apple Gaming Platform. Hells yeah
i like that. the upcoming i7-3820 is listed at $294 which is cheaper than the $299 i7-2600, which is the BTO option for the top end 21.5" iMac at $1699 w/o tax. so take the screen away and replace that with an amd 68xx series gnu and we should get a similar price point. maybe....
The single core system will have a $300 processor and an average GPU (not workstation type) for an Unbelievable price of $2499! Those aesthetics fool a lot of people I guess. Dell's similar model single core is a grand cheaper with a better GPU for workstation stuff. Apple fans really make Apple work for sales

Lighten up, bro. "Itoy" is pretty common in these parts as a reference to the lightweight Apple IOS products.
This is a thread about dual socket Xeon workstations, after all.
If you have lightweight needs, the IOS devices are all you need. Many people who do real work outside of a browser or mail client, however, are concerned about whether the "post-PC" (or "post-Jobs") Apple will continue to create systems that meet their needs.
And I'm just amused by the thought that dual-socket Xeon workstations are needed by some who create IOS applications.
Lol, I'm not heavy, bro. And I've been around these parts for a while.
I think those people might be right to be worried. They weren't getting much of what they wanted while Jobs was around either. And given what a small part of Apple's revenue the Pro is, I can't see that changing too much. I doubt it's going to disappear in the near future but I suspect its long-term prospects are dim.
Nah, I'm waiting for Haswell.

DP Xeon's don't appear to overclock like Core i7, though versions at a higher TDP ratings, probably can sustain more simultaneous cores(up to 8 per processor) at max clock rate. My take: Core i7 better for single threads, advantage swings to Xeon as threads increase like rendering or encoding.
Dual QPI vs single QPI in only Extreme Core i7 editions vs frontside bus in other Core versions. My take is Xeon's have significant data bandwidth useful especially for video.
Xeon ECC memory might be an advantage for certain mission critical applications: if you need it at all, you will all ready know this.
I would almost guarantee that there is no future where Xeon will ever match the Core i7 single thread performance even within the same generation, and with Ivy Bridge Core i7 set to arrive in the same time frame as the Sandy Bridge Xeon, it could look even worse.

As a developer I don't discount your claim. It's very important moving forward as more and more 3rd party apps leverage LLVM/Clang/GCD/OpenCL/OpenGL 3.x/4.x as it becomes available for their Pro Apps.
To the Consumer, Xcode is unimportant.

The quad core i7 iMacs (21.5 and 27) will run all of that brilliantly. Heck even the i5's might just run it all very well too. The need for a Mac Pro is smaller then ever now cause of how good the iMacs are these days.
I think:
High amounts of RAM (over 32GB cause the iMac can to that though it's expensive, but 16GB should run all of that just fine)
TBs and TBs of internal storage
User upgradability beyond RAM and hard drive
A need for more then 4 physical cores (though hardly any apps are optimised for more then 4 cores)
Are the only reasons to get a Mac Pro these days. If it's just to run the above mentioned apps then an i5/i7 iMac will suffice very well.
And I believe this fact alone is why the Mac Pro is not as popular anymore.
Damn you
Perhaps that 27'' 3.4ghz quad core i7 modded at OWC with a ESATA Slot, 256gb SSD + 3tb HDD and 16gb RAM is the right way to go after all...and upgrading RAM & Thunderbolt HDD's down the line when needed and things are cheaper....
Ive been jumping fences over the last month, between biting the bullet on an Imac, and waiting out the next Gen MacPro.
And just when I thought ive made up my mind, someone provided more food for thought, heh.
Maybee I should await the next Imac refresh to be sure

I have 2 platforms. OS X and Linux for Engineering work and development. Both are OpenGL/OpenCL focused and Bulldozer will be the next purchase for Animation and FEA.
I'm building it with Corsair case, 1200 W power supply with GIGABYTE GA-990FXA-UD7 AM3+ AMD 990FX SATA Motherboard alone which runs me over $700 before the RAM, GPUs and CPU.
The rest of the cost will be Bulldozer, 32GB of RAM and GPUs.
Buying a similar Mac Pro with Xeons will be more but not by a large margin.
An AMD 6990 GPU runs over $700 at Newegg. The 6970 jumps me back down to $350. If I'm serious about OpenCL I'm buying 2 of them. so I'm back up to $700+.
With the Bulldozer CPU and RAM I'm back up around 2k+ I assemble myself.
If I were to build the same with Dell or HP it's over 3k, if possible to build one.
The first Opteron 4200/6200 12-core Bulldozer chips are arriving at the end of September.
I'll have more interest in Apple's Mac Pro when there is the option to BTO for either Intel or AMD. I'd rather buy a few Mac Minis for XCode development and only after I need the extra horses after I've bought the Bulldozer box will I invest in the Mac Pro.
I see all three needed for my goals, but all in due time.

I came to that conclusion as I am a Solidworks user (on PC and I'm looking to migrate to bootcamp) and the benchmarks for the extreme editions of Core i7 are just blowing away Xeon's.
On the other hand, I also want to get into rendering and most of the popular apps will use all the threads available if not all the cores.

Ultimately, the decision comes down to support of the Nvidia Quadro 4000 through PCI-e on the Mac Pro, which is beneficial for some Adobe apps such as Photoshop and After Effects.
Ivy Bridge processors in the next iMac would be quite fast enough I suspect, and worth the wait.

hahaha. i was doing the same thing. building my rig in my mind using the internet. i set my budget to be realistic, though. but it was already decent consisting of gtx 560ti (for cuda and decent gaming performance), i5-2500k (for oc), gold plus psu (saves on electricity bill?), 8gb ddr3 1600 ram, fractal r3 case arctic white one (looks like a mac) and a oc-friendly motherboard for around $1200. i was really happy with the figure and made me think really hard about it. but, as it is a luxury item and i don't need it for work, i had to pass up on it.
i was switching back and forth between intel and amd and my reasoning for choosing intel was mostly timing. bulldozer is not out yet and the only thing available right now are last gen phenoms, while intel already have their sandy bridge cpu's with upgrade path next yr for ivy bridge. so choosing amd would have meant spending on a cpu that might get updated in the next month or so. mind you, this was all just window shopping. but, i really approached it as if i was going to build a pc, researching everything from mob's to psu's, etc.
so. even though, i came out empty handed, i think, i learned a lot just by window shopping online. lol.
so, what kind of work do you do to require such gnu power?

so, is hotmail. is hotmail really down? can't access it here.
the MP can't come this early... That would be more than 2 months before Intel's official release. I can't see this happening right now. (unfortunately)
