Win 10 to get Microsoft's own Xbox emulator?
 

Not out of season aprilfools, it looks like M$ itself wants to emulate Xbox on PC. Instead of silly "Playstation now" service that has no emulation whatsoever but is pay2stream rubbish.

I'm not sure how this is supposed to work "under the hub" exactly on the usual gaming PC which is quadcore without threads. As you already know jaguar is basically an octacore (two modules with 4 cores each), but with almost halved clock compared to CPUs we see inside an usual PC. The very same AMD however made Ryzen series where 1400 and higher or in next series 2500 and higher, although at least quadcore, allow threading. Shall we have to "upgrade" CPU in our gaming rig if we want to play Xbox games?

I'm not sure in fact about anything here, only that something odd is going on. Since the game used as demo is Xbox version being downloaded to testers (aka insiders), maybe Microsoft simply wants to give to PC audience RDR because Rockstar refuses to do it?
No, it's not some goodwill, Microsoft will definetly earn $ from it - these games will have to be bought from Microsoft's store, not Steam. Or, a victim, will buy Xbox DVD, not PS4 DVD. ;)

Hm, interesting find. So instead of shitty xbox->PC ports, we now get to play the shitty emulation. ;)

But seriously, this would open up some interesting games to me, so let's see. I'd just hate the MS store part…

It would seem a bit crazy to introduce an emulation layer, but I could imagine something more like WINE on Linux, that translates the calls from Xbox games to Windows APIs. Since it's all in-house, it's probably manageable, and makes sense from their point of view. But would this mean no need for proper PC versions at all?

Considering how long actual computers have been available in homes now, I'm amazed that consoles are still around. I still think we'll eventually get to the point where we have one box for entertainment purposes, and this could be a natural step along that progression route. Firstly we'll have to see if it truly happens, and then just how well it functions.

Have to disagree a bit. :)
We'll have one box at home for "immersive" purposes, and another to carry around and occassionally pay2win to pass some time (phone).

Might be very easy low effort also might be an indication of (from MS perspective) tighter integration between xbox/ms business groups ?

I highly doubt there's much of any emulation (relatively). Xbox One is x86, so most of it is probably going to be running bare metal.

Well, Microsoft has certainly been into the whole virtual machine thing for a good, long time now so they could pull off a virtual Xbox machine. They might need some pretty cranking requirements in order to deal with that shared-memory thing that the consoles use, though.

Is the shared memory visible to the application layer ? Another thing would be if these programs use timing loops. Hopefully not but some coders are pretty sick in how they implement things…

I'd be surprised if they went with the overhead of a VM. Most VMs these days use hardware pass-through, rather than true emulation. If the hardware is sufficiently different to require true hardware emulation in software, the performance penalty is likely to be unacceptable.
