Though this topic present over different forums with different confusing discussion but I couldn’t find any instance of it present over here at StackOverflow and it could be
Yes, it's absolutely completely impossible, done, finito, acabado.
Why is it so hard for everybody to understand that? It's documented everywhere, and you'll be told so when installing, and attempting to run the emulator.
Well, while I'm sure you're right and it's documented somewhere, it was only after installing and running Windows Phone 8 SDK on an iMac (with i5 processor) under Bootcamp gave me the confidence to overwrite the Windows 7 partition on my MacBook Pro (CoreDuo), Buy Windows 8, install it all, go through the (rather lengthy) Windows Phone 8 SDK installation again and, only at the very end, be told "this computer isn't compatible with Windows Phone 8" etc message.
Ok, I could have looked harder at the documentation, but I figured a trail run on an iMac was a good test. It's a pretty non standard requirement too - "Must have a SLAT processor".
I get the benefits etc, but I think it's pretty poor user experience to only be told this at the very end of the installation process.
