SM-N920T stock 6.0 vs 7.0 firmware benchmark results comparison

Howdy!
Here is an AnTuTu Benchmark of two T-mobile Note 5's Both Stock Firmware with limited amount of apps running.
Left is one with official Update to 7.0, right is the stock 6.0.1. ???
Is this for real??? Can I get to 7.0 without losing performance?

Benchmarks say nothing. You can run several test and all of them will be different.
