is Spartan 64-bit?

In the 64-bit version of Windows 10, is Spartan 64-bit or 32-bit? I can't install Windows 10 (work computer, not allowed to) so I can't check for my self. Thanks in advance

I imagine there are two versions, 64bit and 32bit as there are two versions of the iso (x86 & x64) for the technical preview.
