I'd expect it to be roughly the same, though
The Gravity DOP itself is not multithreaded, but for good reason: it's not a solver - it just adds a description of the force to the object, which the actual solver is then responsible for evaluating later on. So, the Gravity DOP itself isn't doing much work beyond evaluating the parameters.
The POP Solver (via GAS External Forces) and Bullet solver are both multithreaded when *applying* forces such as those described by the Gravity DOP
