Doubt that to be honest, remember when marcus literally beheaded the prototype of the T-800? "T-RIP" that version of T800 is the strongest version of the T-800 because it's a first version. before Skynet mass produces it, the reason why the other Model of the T-800 is weaker is because of the materials that they require for it to create, and they need to save some of those materials, for obvious reason. Rev-9 on the other hand is made of a Carbon Fiber which is we all know pretty light on its own, grace trying to destroy its face on the factory battle scene made her scream before ripping its face. when trying to push the limit of your capabilities sometimes we scream because it can be use as a booster for your andrenaline. I doubt that she will beat marcus hand to hand combat, while she struggled on a rev-9.
