In this case, the information I needed to answer your question was included in your question. But I also have a third-party source definitely confirming this.
Third-party source: http://www.anandtech.com/show/8864/amd-fx-8320e-cpu-review-the-other-95w-vishera (it's in the details)
First-party source (your question):
All a CPU requires, strictly speaking, to run Windows 10 64-bit is support for the "AMD64" microarchitecture (variously referred to as X86_64, x86-64, x86 64-bit, etc. etc. etc.) Note that no CPU manufactured by AMD will ever support "EM64T", but EM64T is just Intel's specific implementation of the AMD64 architecture. It's mostly compatible with AMD's own implementation, enough that Windows 64-bit will work just fine on either one.
Only a few very low-end Intel processors manufactured for small tablets and smartphones are still being manufactured in recent years without 64-bit architecture support. All other Intel x86-based processors are shipping with 64-bit instruction set, including those from AMD. This means in practice that if you have a full-fat laptop or a desktop from, oh, the past decade or so, there is very little doubt that you'll be fine running a 64-bit OS.
The less-certain question is whether your system components, like RAM, disk, and graphics chipset, are good enough to run a new version of Windows. But in your case you should be fine there, too.
But, yeah. Whenever you upgrade to a new operating system at all -- regardless of whether you're migrating from 32-bit to 64-bit, or to a new version, or from, say, Windows to GNU/Linux -- you still need to consider, component-by-component, whether they meet minimum performance specifications required by that operating system, as well as having the appropriate drivers available. The CPU is not the only component to consider for compatibility, though it is definitely an important one!
