I disagree, While those custom APU usually ends on game console and may end at some VR related devices, this will not be the case at Apple, Apple TV will remain with Ax chips same for VR, since Apple develop those chip in-house no need for amd help, not the case for Mac hardware since they need amd64 compatibility they need either Intel or AMD, Intel don't sell customized cpu, so AMD Is the only available vendor.That APU customized is for AppleTV/Console competitor from Apple with VR capabilities.
Absolute no sense, Why 4 people at same time shares an APU For VR? As long I know each VR display is attached to a single gpu, group sharing an VR app or environment, are linked via network as today is done with every multi user game.The question is this: Will AppleTV with AX chip provide enough performance for 4 people using VR at the same time?
Thank you
Seems you don't understand how VR works.There is also Virtualization on GPU, Mago.
Why sharing the same hardware? Imagine TopGear VR, that attracts whole family at the same time. VR is everything. Not only gaming.
Actually I was asking if Broadwell EP that will use DDR4 can use Non-ECC memory. Maybe I worded it incorrectly that it was not obvious.that is completely and utterly inaccurate. ECC Ram is not keyed differently at all. the only difference in ECC from regular memory is some extra circuitry on the chip. The only question is if the CPU supports it, which it unfortunately does not. DDR3 is DDR3, DDR4 is DDR4, there is no physical difference in keying between normal, ECC and Registered memory.

So In a word, it is possible to use Non-ECC memory in Mac Pro?

This is an relaxed/economic position about expensive components is somewhat digerible, but don't apologize him about not using a reliable approach.http://blog.codinghorror.com/to-ecc-or-not-to-ecc/
Post from Jeff Atwood on ECC.
Which is a moot point for the nMP since any data transferred to and from the GPU may suffer from errors as the VRAM isn't ECC itself. This is why on our workstation that are used for heavy gpgpu processing in simulation work we make sure all the data path is ecc.This is an relaxed/economic position about expensive components is somewhat digerible, but don't apologize him about not using a reliable approach.
ECC ram not only is useful keeping up the servers, more important it prevents bit-riot, when you work with original data you want it unaltered across the time.
Workstation use to work longer unattended too as servers also benefit from avoiding memory errors.
Also storage it's prone to bit-riot as to other corruption.
ECC maybe not necessary for gaming or word processing and many task as those cited by koyot, but if you're running a long number crushing algorithm looking for an small singularity and then your ram is corrupted on a way you can't detect you could end finding that the sun is hidden under the sea and not beyond the horizon.
Ok that's something for mortals as us, but did anyone know about mission critical servers as IBM's Z3s which not only are ECC their also are the only machine available with RAID Memory banks you can hot swap DIMM w/o corruption or stopping the processing, imagine being capable to do that.
It depends, if you use your gpu for rendering is not a issue, also isn't an issue of certain processes which implies data degradation as transcoding.Which is a moot point for the nMP since any data transferred to and from the GPU may suffer from errors as the VRAM isn't ECC itself.

Maybe I'm not following your phrasing exactly, but RAID RAM and hot-swap DIMMs are pretty much standard across all mainstream enterprise servers. HPE ProLiant x64 and x86 servers (except for entry level) have been able to do this for a long, long time.Ok that's something for mortals as us, but did anyone know about mission critical servers as IBM's Z3s which not only are ECC their also are the only machine available with RAID Memory banks you can hot swap DIMM w/o corruption or stopping the processing, imagine being capable to do that.

I have both presently at my desk... The notch on the ecc stick doesn't line up with the non ecc.
...and another one. I've used Macs since forever (Quadra800 !).From my perspective, MacVidCards has a "real world" view of this topic.
I'm still running an old mac pro for my bread and butter.
This is this first time in many years that I haven't bought in to Apple's latest solution.
Now the latest box is 3 years old in tech terms.
Seriously? Apple? Is this the best you can do?
Mac Pro?
Seriously?
Apple?
The fact is the nMP is based on two big bets. The first is that all but niche uses will transition to HBM-based video cards; this bet still seems right, but the transition is many, many years behind the expected schedule, and in the interim the nMP is making some rather large compromises.
As a betting man I'd guess there will be a 2016 nMP, and the high-end GPU will be a cut-down Fury Nano derivative updated to use HBM2 (thereby able to hit 8GB); the other GPU models will be updated, but of similar vintage. It'd be cool to jump straight to AMD polaris, but it just seems unlikely. The CPU will be whatever is available.
