If you want sth to compare against my vcore maxes at 1,236v in games, the CPU is running "stock overclock" cause I set it to 4400MHz with all cores active and the base clock to 4400MHz too. Another thing, I'd also try to see which has lower temps if you're not delidding, maybe one of them has better TIM job than the other, you'd have to stress them both with stability benchmarks and if the difference in max temp is 5 degrees or more I'd take the cooler one. Remember to take notes of the ambient temp, it has a lot of impact on your components.
And btw ASIC is no indication of OC capabilities. I had a 75% ASIC 980 G1 and it couldn't run 1500MHz even with any sort of voltage bump and only 1440MHz with stock vcore. People with 67% ASIC 980's got better results than me.
