There is no computer processor in existence that has a rate of Petahertz per second, because of Moore's law. All modern processors today have a max turbo speed of around 5GHz per thread and even that can only be sustained for a short amount of time and then it reverts to it's base speed of around 2.5 GHz per thread. Since you're assuming this can be done on personal computers, even if you have say 8 cores then that's only a combined base speed of a little more than 16GHz per second.
And even then these numbers are just for CPU instructions, the process of finding a SHA256(SHA256(x)) hash has severely lower rates than what I posted.
Look at this table here
https://en.bitcoin.it/wiki/Non-specialized_hardware_comparison. Look at the Mhash/s column, every processor listed only has megahash speed.
You know that CPU XEON 2680v2 can brute-force public key (secp256k1 curve) at speed 55TH/s per thread
No, it doesn't. According to the link I just posed, double Xeon E5-2690 processors (in the same family as 2680, since 2680 isn't on the list) has a listed hashrate of 66 Mhash/s. So it's safe to assume a single Xeon E5-2680 can do 33 Mhash/s
for the entire processor.
This screenshot looks like you hacked up a visual basic program and coded it to print sketchy results. 55 TH/s sounds very dodgy, like you're using an Antminer S17 with 56 TH/s as the mining source instead.
Move away from gigahertz, look more abstractly...
if you need, for example, to get 2^2 and then 2^3 .. you can of course go by adding or multiplying or even raising to a power)) and spend a lot of processor time on it.
Or you can just shift the bit to the left.
In both the wine case and you get the same result. but spend a miserable resource on it.
And ofcourse i wiil say that second way will much more efficiency.
