you see it here:
https://rog.asus.com/forum/showthread.php?104231-Asus-ROG-G752-model-confusion-VS-VSKMy results is that 302 have better performance and the 304 have a 2-5% lees performance
But also i have the lowest temps with 304
Benchmarks with fan at max
Room temp 26 degree Celsius
With the same configuration on each benchmark
this test is only for my personal knowledge
awaiting others user to make similar benchmark and post results
after updating you bios you can return any time to previous version
