You still haven't answered why hUMA will be a small facter.

Can I see some sources saying you don't need to emulate an x86 cpu for the xbox ? 

Why would an X86 processor need to emulate an X86 processor beyond a code wrap?

Because apparently they need to code for how an x86 cpu would emulate multiple instruction exection.

Not always.
SNES 9x isn't very accurate, it is however "Good enough" for the majority of people, if you were to emulate that console with 100% accuracy and at full speed, you would need a stupidly fast system.
BSNES being a good example of a more accurate emulator.

Also, my comment wasn't rash, it was logical and I gave reasonings why and people have done it.
Heck, Cxbx isn't even an emulator, it's a converter, well it started out that way anyway.

And I quote: "the code that tends to eat up the CPU) can be executed directly."

The thing is, the Steambox isn't going to have Infamous Second Son, Final Fantasy 15, many JRPGs, etc, while most of the bigger PC titles will be on consoles. If that's the case, what's really the point in getting a Steambox when it's going to be more expensive than even the Xbox One and it's just a poor mans PC?

It is supposed to be Linux based, so it isn't going to run PC software.  Stuff for it will be designed around gaming in the living room.  Different experience pretty much.

Because everything needs to be multiplatform now adays^

What I heard from PCSX2 developers is that you need a fix to get around the issues of accuracy.

And look at the quote before. "a large precentage" That means that there are still some issues to using a direct code to execute on the cpu. 

Consoles don't get: StarCitizen, Arma, Heroes of Might and Magic, The Settlers, Civilisation, X3, Sins of a Solar Empire, Red orchestra, Company of Heroes... etc' etc'.
All platforms have exclusive games, whether the platform is attractive should come down to personal taste in games, Personally I have no interrest in Japanese RPG's or most of the console exclusives besides Halo essentially, they're usually dumbed down and full of quick time events with poor image quality anyway, but that's my personal opinion.

Would I get a Steam Box? No way. I love my Display set-up too much to go back to 1080P.

Now you're arguing for the sake of arguing, I did elaborate on that.

@Bold 1 I'm pretty sure mario(atleast 2D) is more relevant than all these franchises combined.

@Bold 2 I know that you did elaborate on that but it's far from easy to emulate the xbox. 

I still don't know about your thoughts on hUMA.

Edit: I have another question, umm how will older DX11 gpu's be able to emulate the PS4 and xbone if their programability and efficieny has increased drastically compared to VLIW ?

Edit 2: Will newer gpu architectures abandon things that were in the GCN architecture such as when nvidia made a switch from fermi to kepler and decided that it was best to drop a hardware schedular ?

Edit 3: How often will developers abuse specific features of the GPU to the point that it will be harder for other gpu's like nvidia gtx series to emulate them ?
