AMD A10-5800K Performance On Ubuntu Linux
For the other NPB tests like Multi-Grid and the Scalar Penta-diagonal solver, the A10-5800K remained faster than the Sandy Bridge Core i3 CPUs but behind the Core i5 2400S Sandy Bridge.
AMD processors don't tend to do too well for the Dolfyn test, which provides a fluid dynamics workload, but at least it was a bit step-up over the Llano APU and the overclocked A10-5800K to 4.4GHz ended up being faster than the first-generation FX-8150 Bulldozer.
LAMMPS as a molecular dynamics simulator is a similar story to Dolfyn with generally not doing too well on AMD processors -- even the FX-8150 was slower than Intel Core i3 CPUs. This is even when all of the test profiles were built from source on each of the CPUs and with -march=native tuning.
