Hello, You won’t need to reinstall Windows 8 unless you’re upgrading from an older version. Using your old key should work if you’re replacing the hardware.
It seems you're recalling a process where you input your key and are prompted to select an option for MS. They provide a phone number that connects you to a computer. This method might suit you, as your W7 key functioned correctly after switching from AMD to Intel.
I transferred a Windows server setup from an AMD Athlon 64 to an Intel i3 560 without problems initially, though I can't confirm it will hold up. It's uncertain, but it might be possible. EDIT: Windows will recognize the hardware change, so what matters most is the requirements.
When Windows attempts to start, it will inform you about the result—success or failure—and offer alternatives. If it fails, you’ll see choices like activating via a phone call. You’ll review several options and then enter a long code displayed on your screen. It will return another code for you to input into the machine, which will complete the activation. As @manikyath mentioned: it might work without reinstalling, but changing between Intel and AMD chips often doesn’t succeed, so I’m skeptical about that.
