Not just the sum but the quality might be even lower. If it is like OTL and people don't know he wants to murder them all you could see a couple of Warlord clans allying with Hitler right off the bat. And production is going to be so much lower than OTL. I doubt a warlord state will be producing tanks. Troop quality is probably going to be horrible as well. And there will still be internal strife.
If anything I think the troop quality would be better than OTL; large parts of the Red Army consisted of poorly-equipped, half-starved conscripts with a gun to their back. That's how they managed to field so many of them. Of course, the red army was a very large institution, and some divisions would certainly be better trained than others.
Wiki says that the Eastern Front was responsible for 75-80% of German war losses during WWII. If the Russians are replaced by infighting warlords, it would help Germany immensely.
