I searched the same site for a datasheet for an AMD Phenom II X4 850 (the processor I'm looking to buy) and again found only the compatibility for SSE2, and PAE (again listed as AMD64). But when I check it I can only find the compatibility for SSE2, and PAE (listed as AMD64). A thread on this site, a user named Carsomyrclaims this datasheet for an AMD Athlon II X4 640, is compatible with all those things. But I have no idea how to check for that without physically having the CPU. What I've found is that in order for it to run Windows 10 64-bit, the CPU needs to be SSE2, PAE, NX, and CMPXCHG16b compatible. I want a CPU that is capable of running it, but everything I find online how to check if it is compatible, only works if you already have the CPU installed. If you see x86 based PC, then you can't install another architecture of the operating system.' Well it shows x86 based PC despite my 64-bit processor. One website said to check under System Information 'Look for system type if you see 圆4 based PC, then your computer is capable of running 64-bit Windows. I have a AMD Athlon 64 X2 Dual Core 5000+(64-bit processor) and I'm thinking it can't run WIndows 10 64-bit.
