This workload is based on the OpenFOAM open-source CFD solver. The OpenFOAM solver XiFoam is used to solve compressible premixed/partially premixed combustion with turbulence modeling.

The Poisson equation is an elliptic, partial differential equation of second order, which is used as part of boundary value problems in many areas of physics. And here we see a very interesting exception, because the Core i7-12700K pushes itself to the very end and even the Core i5-12600K acts faster. Obviously the thread director was on vacation, because you can already see in HWinfo64 which P-cores are (not) used. This was classic thread yo-yo towards e-cores and back, and it also shows that of course even Intel probably needs a few more patches until everything is running smoothly.

Rodinia is a benchmark suite developed by Professor Kevin Skadron and others at the University of Virginia to test heterogeneous platforms. It includes the following tests for a medical imaging technique to track motion of a set of sample points in the image of a beating heart, compute particle potential and displacement due to mutual forces between particles in a large 3D space includes a thermal simulation to estimate processor temperature, and an algorithm to remove speckles in an image without affecting its features.

The Pre-Euler3D CFD test (Computational Fluid Dynamics Benchmark) preferably runs broadly on as many cores as possible as well as on a high-performance platform with a fast memory connection. This is exactly what you can see in the bars.

This workload deals with the processing of seismic data. It implements a Surface-Related Multiples Prediction (SRMP) algorithm written by Evgeny Kurin of GEOLAB Ltd. to remove multiples from seismic data. 12 cores are apparently more than 16 and it wins the Ryzen 9 5900X.
