Xbox One (Durango) Technical hardware investigation

I'm pretty sure there is already a thread about a short upgrade lifecycle (2-4 years) somewhere, so I'm not going to get too far into that, but it does allow them to keep their price high if they're selling the units. Just saying this model, if true, may allow them to do that.

Its already proven effective from Apple, same tiered price points, more 'stuff' over time.
 
Virtualization means you can change the underlying hardware and run it on massive servers ala GaiKai right? At least, you elongate needing to build servers with specific hardware and instead just pick powerful components leading to better scalability, no?

I may be talking out of my ass (and probably am), but it seems like the steps Microsoft is taking is such that the next step really is cloud gaming and this console could be "forward compatible" in some sense that its designed to also be run on a cloud infrastructure. If Sony knew that something like GaiKai or OnLivr would be feasible in the near future when they released the PS3 in 2006, do you still think they would have gone as gong ho with Cell? (granted, the dev cycle for that chip started in 2002 so the answer is still obviously yes)

"...just like Apple do" is the start of many a ruinous business plan. They exist in a separate plane from most companies and can command higher margins than anyone else. Why is this? Lord knows but everyone else has made a lot of money writing books trying to get the answer.

If you want a platform with fast iteration and better graphics buy a PC. Console manufacturers promise software makers a nice fixed target with a long life cycle allowing them to make better returns on the huge investment in tech. and personnel at the start of each console cycle. If this is MS business plan you could expect to hear a lot of unhappy publisher noise long before now.

Not necessarily, though that might not be a bad reason to do it.
It just means that the application sees a machine that may not match the underlying physical structure of the box.
For example every application might see 8 CPU cores even if it's currently running on 2. For parking applications this is a fairly nice way to do it.
Also means the Game OS is probably part of the game binary, so you could run two games dependent on two different versions of the Game OS without the need for backwards compatibility.

The bigger issue to me is how the GPU is virtualized do games have to deal with device lost type scenarios? if I write a GPU compute job that errantly take 9 hours to complete can the hypervisor reset the GPU? how is the game informed of that? does it have to survive?

I think you and the others are confusing this Durango tech thread with this upgradeable console discussion.
 
<Edit>
On second thought this post was still OT.

Has there been any revealing posts on the extent of virtualisation with Durango or whether the cpu supports the full AMD-V stuff including I/O virtualisation?

I don't think there's been anything so far that would reveal if Durango supports AMD-V, or whether the GPU would support virtualization under Microsoft's RemoteFX for Hyper-V Server (assuming the rumour is true and it uses a modified version of Hyper-V Server as the host/root OS). Only AMD's Firepro GPUs officially support virtualization. I don't know what's different about the hardware and drivers to support that feature.

I'm sure the answer lies somewhere in the TechNet documentation on RemoteFX for Microsoft Hyper-V Server 2012, but I never found links to in-depth technical info when I was skimming over the topic.

AMD cloud gaming are serviced by AMD's line of SKY branded gpus. I think virtualization is important to MS as it would allow Durango to serve as a cloud like server to other devices that are part of MS's planned 720 ecosystem.

RemoteFX and AMD rapidfire tech would help facilitate Durango's streaming ability. I wouldnt be surprised if Durango GPU is a FirePro or SKY based derivative.

The relevant parts of GPU silicon are likely the same. The presence of upmarket features is usually a matter of fusing, firmware, and drivers.
 
Is this the specifications update VGLeaks mentioned days ago?

I can't wait for my Durango w/DDR4, my VitaHD with a 4k native display and my 3DS Pro XL with GTX 680 SLI onboard! I particularly like the '12GB DDR4' as if a paper RAM type wasn't enough why not go with 50% more quantity than PS4! And go faster stripes too! And a pony!

If that is what VGLeaks were quoting then thanks Cyan you've saved me the time spent reading their site in future.

I think fakes like this say more about the nervous state of some fanbois than it does Durango. Which is odd as I haven't read anything that suggests it will be 'crushed' by PS4. I'm still fascinated by what the Move Engines are and what it is they are supposed to accomplish, I don't recall any good detailed leaks on these beyond claims they are the 'secret sauce'. Come on MS show us your tech docs!

Lots of detail already leaked, probably from official MS doc.
