Yep SPARC is a tokamak. It's about a tenth the size of ITER, but should get the same output because they have better superconductors. Tokamak output scales with the fourth power of magnetic field strength: double the field, 16X the output.

I think SPARC has a shot; they are designing for sustained fusion and with the work already done at JET and other tokamaks they will be starting with great data on how to manage plasma.
