AMD A10-5800K Performance On Ubuntu Linux

CLOMP was the first test run across the spectrum of Intel and AMD x86 processors. CLOMP is a simple test that just measures the OpenMP efficiency across all available processing cores. OpenMP remains very common for parallel programming. To not much surprise, the Intel Sandy Bridge and Ivy Bridge CPUs did much better when it came to measuring the OpenMP efficiency and their numbers were much closer to their respective number of physical/logical cores. The quad-core A10-5800K had a speed-up of just 2.51x, which was even behind the Intel Core i3 2100 that is just a dual-core part with Hyper Threading while its speed-up was 3.15x.

Moving to the NAS Parallel Benchmarks from NASA, in these popular scientific tests, the AMD A10-5800K was coming in just behind the Core i5 2400S. The i5-2400S is Intel's mid-range quad-core Sandy Bridge processor that is clocked at 2.5GHz with a Turbo Frequency of 3.3GHz. For EP.B, the "embarrassingly parallel" workload, the A10-5800K came ahead of the i3-2100 and i3-2120 and right behind the i5-2400S. When overclocked from to 4.4GHz, the A10-5800K was well ahead of the i5-2400S.

For NASA's Lower-Upper Gauss-Seidel solver, the A10-5800K Trinity remained ahead of the Core i3 CPUs that were tested but even when overclocked it came up short of the Core i5 2400S. At least the A10-5800K remained measurably faster than the previous-generation A8-3870K.
