... . However, as far as the vast majority of users are concerned, I think making the system a dual socket Xeon with a single GPU would have been better than the current single socket CPU with dual GPU config.

There is little to no quantitative evidence that two socket systems outsold the single sockets in earlier models. Duals where over represented in the 2007 era because that was the only way to get to 8 cores. Once could get to 6-8 single socket. If the overwhelming vast majority of users bought such systems then Apple would probably still be making them.

"... In the past six years, the SFF workstation has been the fastest-growing machine type, now accounting for roughly 40% of all entry-class deskside workstations shipped (source: Jon Peddie Research). ..."
http://www.cadalyst.com/hardware/workstations/next-generation-small–form-factor-sff-workstations-26262

That's one reason why the single socket 6950X (covered in the review linked below ) costs more than 10 cores than buying two 8-10 cores Xeon E5 v4's. People are going to pay for the more compact form factor ( and the single threaded performance is higher also when just need that).


Apple isn't aiming at 100% of that same SFF market ( smaller still enclosure , but keeping more of the E5 and custom GPU focus). But the notion that the larger collective isn't moving toward smaller ( via laptop or more comfortable fits on the desk" ) doesn't measure out if do broad spectrum sampling.

For folks with "lowest common denominator" software even the single socket E5 has some limitations.

In the adobe benchmarks here:
http://www.tomshardware.com/reviews/intel-core-i7-broadwell-e-6950x-6900k-6850k-6800k,4587-5.html

the Core i 6700K is coming out in front in several of these. If following the "most users usage" then 4 x86 cores is plenty. Also points out why Intel is more than a bit goofy to kneecap the 1620-1630 at probably artificially low base clock rates for those price points. Yes, in the rendering corner cases the cores do pan out. However, if option of After Effects on x86 and after effects on GPGPU where the software quality is the same who is choosing CPU?



For all the noise that's been made about GPGPU computing, it still hasn't really replaced pure CPU muscle in my view. The second GPU in the Mac Pro seems to often sit as a case warmer in the system.

Even the pure CPU muscle though is coming to a single slot. v2 maxed at 12 cores. v4 maxes out at 22
http://ark.intel.com/products/family/91287/Intel-Xeon-Processor-E5-v4-Family#@Server

v5 will have 22 that isn't quite so ridiculously priced. Over time the "2 socket NUMA implementation" is being implemented with a single socket. The number of folks who are sitting on relatively static software that scales past 15+ x86 cores is shrinking; not growing. The individual cores are better and the performance is "good enough" for a larger set of folks. There is a set of folks who "there can be not enough cores", but they are never were in the majority of users and that number is shrinking of whom need a 100% time committed used on only one individual system physically on/under their desk.

That said Apple hasn't done as good a job as they should have in getting more software deploy that takes full advantage of the hardware deployed ( both in Mac Pro and other Mac over last 2 years that were reasonably GPGPU capable. )

Great... so we'll still get Macbook "pro" with intel graphics...

if it is latest generation Iris Pro with eDRAM acceleration the performance isn't going to 'horrible'. ( should be sufficient to drive a 5K TB display/docking station for mainstream MBP work. ) In terms of space and cost efficiencies, Nvidia has nothing to offer for the bulk of the MBP line up. Performance wise AMD still has problems from a holistic x86+GPU perspective.

There is only one standard model with a dGPU for the last year (or more) [ upper end 15" ] :
http://www.apple.com/shop/buy-mac/macbook-pro

The reality is more so on how soon Apple drops that outlier rather than if the dGPUs with take back any design wins they've already lost out on in previous years (or were never in).

That trend wasn't going to reverse with anything Nvidia/AMD is offering the short term. Even with the move to HBM ( GPU+Memory all on a chip to get somewhat competitive in space efficient dimension ) that isn't close to moving into the mobile landscape any time soon.

Intel is the largest GPU vendor that Apple (and most of the market ) deals with. It has been that way for several years now.

E7 minimally $1223 per processor ( median price up near $4600 ) ... probably a higher priority than the incremental gain on selling the E5 1600 v4, when over the short term can simply sell the Core i7 69xx and 68xx at the same prices would be selling the E6 1600's at anyway. Not like they are loosing money by waiting until the initial demand bump/bubble for the Core i7 variants dies down a bit. They can keep the production line going at a steady pace longer if they just stagger these two variants of the same basic die.

AMD had nothing to counter with and will have nothing to counter with probably for the rest of the year. The customers aren't going anywhere in the mean time.

Beta 2 out.
[doublepost=1465243167][/doublepost]Yeah, but i7s and Xeons don't go in the same machines.
I'm guessing HP, Dell and the rest want to update their lineups, 1S WS and SFF.
I'm not saying it's an urgent need, but they have the conditions to present the full spectrum.
But maybe the HEDT market is more valuable to Intel than the 1S WS.
Maybe the production lines are in full swing for the i7s now, indeed.

The ones with the same sockets can. 69xx and 68xx . It is the same package and physical socket. The chipsets x99 and C610 are more capable than previous generation ( there is small corner cases where diverge).
Not talking about the whole i7 line up. It is not a uniform line up. Just the subset that is based off the E5 design ( Hence, comes out only around the same time as the E5 updates roll out. )

Can slap a 69xx in a C612 machine if wanted to and installed the correct firmware update. Likewise folks have shoehorned E5 into x99 boxes. Not really optimal usage, but possible. Would save a whole lot of almost nothing in terms of overall systems costs for an Apple produced system.


x99 and C610 have same spec update doc.
http://www.intel.com/content/www/us/en/chipsets/x99-chipset-pch-spec-update.html

same data sheet doc.
http://www.intel.com/content/www/us/en/chipsets/x99-chipset-pch-datasheet.html

It doesn't make much sense to put a E5 into a motherboard that is optimized around overclocking and vice versa (i7 into non Overclocking and default ECC context) .


I'm guessing HP, Dell and the rest want to update their lineups, 1S WS and SFF.

It is a firmware bump and processor upgrade they could sell later. They too aren't loosing hardly any customers to any wait. The next iteration will be a socket change which will require new infrastructure.


I'm not saying it's an urgent need, but they have the conditions to present the full spectrum.

provide full spectrum of what is available now ... and they do. ( if trying to be the "everything for everybody" then have gobs of duplication in the line up. Not going to loose much more of anything since have a shotgun spread of products to shoot at customers. )


But maybe the HEDT market is more valuable to Intel than the 1S WS.

The HEDT suffers from far more tech porn envy and attention deficit disorder. Enterprise E5 folks with hardware are typically on a fixed depreciation schedule and are in no a rush to swap out hardware. If the hardware is making money now it will probably still be making money 3-4 months from now. 3-4 months isn't a problem. Folks with tech porn bragging rights lust .... yeah they can't wait.


Maybe the production lines are in full swing for the i7s now, indeed.

If it is formally launched by Intel, then it has already been in "full swing". This only issue is whether there will be an initial supply and demand mismatch. That mismatch does nothing for Intel. It may give the retailers a profit bump but pricing over Intel's suggested level does just jack spit for Intel. So why ? Apple makes hay on scarcity. Where Intel is largely situated in the customer-product chain, it does almost nothing for them. It is actually more profitable if there are no scarcities.

Problem is that MBP has issues on desktop with iGPU and retina res. I don't mind the vendor as long as gpu is capable of handling expose functions without stuttering, but it currently isn't. Just put on the high res retina setting and span a few windows across 3 or 4 desktops. Then do the swipe up gesture to expose all of them. Things get really ugly. It's really annoying when you have to keep lots of windows open and switch between them.

A 5 years old PC with non-retina res, has no such issues under linux when doing something similar with compiz (actually, compiz has way more complex effects). So far, retina and igpus seem a bad combination. Don't know, though, if the next gen igpus finally are strong enough to solve those issues.

2006 (1,1) and 2007 (2,1) MacPros were dual-processor only, I think. The 2008 (3,1) also had dual-CPU standard, but you could get them with a single processor, which was essentially the same but with one socket empty (you could stick a second CPU in there later, if you wanted).

The 2009 (4,1) Nehalem MacPros were the first to offer actual single-CPU models.

I am not sure this is due to the Graphic performance itself.
LaunchPad gaussian blur in fresh Lion 10.7 is more laggy(15fps) than fresh 10.7.5 (60fps) on my Baseline iMac 2007 20". Why? ;)
Switching spaces in fresh El Capitan 10.11 is more laggy (15fps) than fresh 10.11.5 (60fps) on my Baseline MBA mid 2013. Again, why? ;)

These are good points. As a matter of fact, I cannot really determine if it's because of lack of GPU muscle or something else. I can only assume it is, since switching retina resolutions (e.g. going to "1920x1200 look like") things get extremely bad, while reducing to "1440x900 look like" things gets considerably better, but screen estate is too small for my needs. This symptom usually points to gpu, but it's not a proof.

Hence, I've compromised with the medium res which has frame drops here and there. I just hope that someday apple will make a real distinction between pro and non-pro laptops regarding on gpu part as well.

System UI animation lag is a pretty annoying problem concerning Apple-made OSes. The introduction of translucency (heavy implementation of Gaussian Blur) since iOS 7 and Yosemite really boggs some systems down.
What is the model number of your RMBP? If only it is a late 2012/early 2013 13"...HD4000 can not live happily with a Retina display. Never.

Anyway, I digress. Really happy to see the NMP thread come alive again. 6 days ahead.

I wasn't saying they are not platform compatible, just that they (usually) don't go in the same type of machine.
Of course there are always those that mix and match, but what's the point?
Anyway, Apple might already have access to ES for the nMP.

It actually was a good thing when Mac Programmer Workshop competed against CodeWarrior ( and other tools ). The "only" answer is XCode ( or some other sole solution toolchain) typically leads to stagnation long term.

Microsoft's platform is heading more toward Azure ( and software can from whatever hardware platform you have in hand) than it is several hundred million, largely isolated, Windows instances of varying patch levels.

Single GPU is a no go, it would unbalanced the thing.
I'd say there is no way they'll change anything radically on the nMP, this is the way they wanted it to be, and so it will stay, only my opinion of course. I wouldn't change it myself :)

dec, I didn't say you're supposed to OC the nMP, much on the contrary, read again. Apple doesn't want you to surely. I wouldn't do it anyway, it's not a bragging rig or gaming machine. And, as you say, no power7thermal headroom. Only if indeed the PSU is to get upgraded.

Why are we starting the AMD/NVidia war again? Haven't we had enough closed threads?
Pascal is great, indeed. Some compromises had to be made, to be first to market? I don't know, we'll see. Polaris sucks? Let's wait and see. Was there foul play on any side with Ashes? Again, let's wait.
AMD shouldn't have compared setups if the conditions weren't exactly the same, that's a given. They'll suffer for it if it becomes clear. I sure hope they really are getting their act together and acting righteously.
They're both targeting different markets at the moment so they can be civil.

Adobe software does not benefit from dual GPU. But you HAVE to invest in dual GPU because its your only choice. I would like to choose a single GPU and a extra PCI SSD instead.

And no need for a nvidia / ati war. Those who wants or needs a system that also can work with Cuda (Because a lot of content creation tools use it) has abandoned the brand Apple or is going to do it in the near future when they update there system. Or they choose eggs for there big bill for a new Apple machine, and have no cuda accelerators. There is also a group that is lurking for a 2nd hands 5.1

We have learned that Apple doesn't really care about adobe or other content creation users. Its like Nintodo really. Works great with there own suite of software. But when you use something els, you are way better off with a good configured PC.

Yeah, i am sad about this all. But its how it goes
