Question CPU UPGRADE: 6700HQ to 7820HK

[LuxusKá]

Hello Users !

I have a stupid question, but I think worth to ask it. I have an Asus Rog G752VS laptop with an 6700HQ processor equipped motherboard. So, this CPU is okey but all the way it's on his limits with the GTX 1070 Mobile and it's bottlenecked by the CPU !
The question is:

Both cpu's has the same TDP 45w, 14nm, FCBGA1440, and I have a BGA rework station and i have done some reballing on it. This 7820HK will going to work on this board if I flash the BIOS to the 7820HK model of ASUS G752 ?

Or will not going to work, why ?

Thanks a lot !

If the GPU is the bottleneck, a CPU will do nothing for you.

I mean, all the way I have CPU bound, so the GPU is not maxed out ... I want this CPU change if it works ! For me this thing worth, from Ebay with 230 USD. I Think it's okey, for 40-50% RAW CPU Performace, i will gain in every CPU Bound game 20-30-40 FPS ... Especially in Battlefield ! And why I want this change ? Because I don't like "modern" laptops, I payed for this 1700 € in 2017 ! I know, I can sell this and buy a new one but this build is very solid and I want to be solid at least 2 years ... So pls help me, i really want this CPU swap !
