Of course, the two have been trading shots for months -- and when Ronda was out walking her dog in L.A. Tuesday ... she blasted him again, claiming she's the REAL top earner in combat sports.
"[Floyd] said 'You make $300 million a night, then you can give me a call' ... and I actually did the math and given the numbers of my last fight, I'm actually the highest paid UFC fighter and I'm a woman."
She continued, "I think I actually make 2-3 times more than he does per second ... so when he learns to read and write, he can text me."
The photog asked, "So you actually make more than he does?"
Ronda responded, "Yeah, I'm just more efficient."
There's more ... Ronda also talks about her next opponent Holly Holm and how she feels about getting the XXX treatment from porn companies ... and spoiler: she's not mad about it.
