A simple test processor performance
A simple test processor performance using the increment counter. The program displays the performance of thread (s) in relative units (megacycles).
Each thread executes the following code:
int test_count = 0;
while (work == true) {
test_count++;
if (test_count % 1000000 == 0) {
test_count = 0;
updateStatistics();
}
}
Since most mobile CPU during heating reduces its clock speed, the performance can be significantly reduced. Therefore, the test is better to start with the cold CPU.
The test results (button "1 Thread») for some CPU:
- Qualcomm MSM7225A, 800 МГц: 14.1
- Rockchip RK3066, 1.6 ГГц: 33.6
- NVIDIA Tegra 3, 1.3 ГГц: 30.4
