Hi,
In this thread I want to show yous a benchmark I wrote. It is a single-threaded benchmark that runs on the CPU. In this benchmark the CPU has to calculate the orbital trajectory of one million rocks rotating around a sphere in space. These rocks travel at random speeds and at random altitudes, that is why the time varies the benchmark takes to complete.

I intend to create a highscore list for your results in this thread and on my website.

Please post your results like this:

Highscore list:

CPU Benchmark (single-threaded) v1.1

This updated benchmark takes longer to complete which increases accuracy. The accuracy went up by a huge margin because I also tweaked the code.

Again please post in this format:

Highscore list:

CPU Benchmark (multi-threaded)

Here is my new CPU benchmark. It is multi-threaded. This time the CPU has to calculate the orbital trajectory for 100000000 rocks. That is 100 times more than before so don't be surprised that this new benchmark takes considerably longer to complete.

Again, please post in this Format:

Highscore list:

GPU Benchmark

In this benchmark the GPU has to calculate the orbital trajectory of 10,000,000,000 rocks rotating around a sphere in space. At the minute it runs a lot faster on Nvidia GPUs than on AMD GPUs but I am trying to fix this problem.

Please post in this format:

Highscore list:

GPU Benchmark v1.1

This is my new GPU Benchmark. Radeon performance wasn't improved but the new benchmark should run on most GPUs now. Run the benchmark at least twice because the first run will take considerably longer than the next ones because OpenCL has to be initialised in the first run.

Please post in this format:

Highscore list:

OpenCL Dynamic Workload Manager Benchmark

This new benchmark uses both the CPU and GPU to calculate the orbital trajectory of 1,000,000,000 rocks rotating around a sphere in space.The dynamic workload manager adjusts the workload between the CPU and GPU according to their performance.
