does std::is_same has an impact on the performance of the code?

Does is_same has any impact on the code performance? I am using it multiple times in my code to check whether i have to use std::less or std::greater and depending on them i have to retrieve specific values. Is my test sufficient to prove that std::is_same does not really impact the performance of the code in my case?

The code is much more complex than that and I have to use templates. I tried as much as i can to mimic the places where is_same is used.

I compiled and ran the code with -O3 compiler option.

#include <iostream>
#include <vector>
#include <chrono> 

using namespace std::chrono; 
using namespace std;

template<typename T>
int returnVal(T compare) {
    std::vector<int> v = {1,2,3,4};
    if(std::is_same<T,std::greater<int>>::value) {
        return std::min(v[0], v[1], compare);
    } else {
        return std::min(v[2], v[3], compare);
    }
}

int returnValNoTemplate(bool b) {
    std::vector<int> v = {1,2,3,4};
    if(b == true) {
        return std::min(v[0], v[1]);
    } else {
        return std::min(v[2], v[3]);
    }
}


int main()
{   
    
    for(int i = 0; i < 10; i++) {
      auto start = high_resolution_clock::now(); 
      for(int i  = 0; i < 100000;++i) {
        int x = returnVal(std::greater<int>());
      }
    
      auto stop = high_resolution_clock::now();
      auto duration = duration_cast<microseconds>(stop - start); 
      cout <<"is_same duration:" <<  duration.count() << "\n" << endl; 
    
      auto start1 = high_resolution_clock::now(); 
      for(int i  = 0; i < 100000;++i) {
       int y = returnValNoTemplate(true);
      }
      auto stop1 = high_resolution_clock::now();
      auto duration1 = duration_cast<microseconds>(stop1 - start1); 
      cout <<"No template duration:" <<  duration1.count() << "\n" << endl; 
    }

    return 0;
}
