内存访问比移位慢吗？[已关闭]

#include <iostream>
#include <chrono>

int main() {
    const int N = 1000000;
    int data[N];

    // 初始化数据
    for (int i = 0; i < N; ++i) {
        data[i] = i;
    }

    // 计时开始
    auto start = std::chrono::high_resolution_clock::now();

    // 进行内存访问
    int sum = 0;
    for (int i = 0; i < N; ++i) {
        sum += data[i];
    }

    // 计时结束
    auto end = std::chrono::high_resolution_clock::now();
    std::chrono::duration<double> elapsed = end - start;
    std::cout << "Memory access time: " << elapsed.count() << " seconds\n";

    // 计时开始
    start = std::chrono::high_resolution_clock::now();

    // 进行移位操作
    sum = 0;
    for (int i = 0; i < N; ++i) {
        sum += (data[i] >> 1);
    }

    // 计时结束
    end = std::chrono::high_resolution_clock::now();
    elapsed = end - start;
    std::cout << "Shift operation time: " << elapsed.count() << " seconds\n";

    return 0;
