Please point out where in that video they say they have a PowerPC chip inside Xbox One to support Xbox 360 HW?

Please point out where I made the assertion that it did have a PowerPC chip.

How does the x86 chip contain PowerPC instructions??


x86 chip doesn't need to contain PowerPC instructions. - Digital Foundry explained this.

Why do you think x86 Android tablets/phones can run the full suite of ARM Android apps? (I.E. Samsung Galaxy Tab 3 10.1/Intel Medfield and so on.)
I'll tell you why. It is a technique known as "Binary Translation". - Where instructions are translated/interpreted to be compatible with an entirely different hardware environment.
Here is some reading material to catch you up to speed on the topic:

Thank me later.

Microsoft are basically running a the equivalent of HiperVisor Virtual Machine for each console they support.

Correct. But we have known this for a stupidly long time anyway.
In-fact, Microsoft was already dealing with virtualization before backwards compatibility came along on the Xbox One, it was baked into the system from the very beginning.

The guy in the video specifically says "Microsoft has a FULL emulation layer (meaning NO HW) for XBox One that makes the system believe that it IS an Xbox 360".

You should probably watch the video again.

He also points out the PowerPC code is converted to an intermediary language then recompiled for x86 so it running a close to full speed as possible.

So you just refuted the first and second of your quotes. You make my job a little easier at-least.

 Please watch the video again from about 1 minute in and try to understand fully what is being said.

I wouldn't make the false assumption that I am tech illiterate.

So...as I mentioned in my original post, since it is all running in software, in theory you could run it on any PC, that has enough CPU/GPU power. Hell if Microsoft made the code available, it could be ported to PS4 and you'd have the whole Xbox library running on the PS4 or PS5!!

It is not all running in software.
You should really watch that Digital Foundry video again... Especially the part where they start talking about the texture formats and audio tech being baked into the Xbox One's chip.

Or do I really need to do a Youtube embed that starts the video right when they make that statement?
