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. Advantage Intel.
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 i5-12400 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. Of course, the Core i5-12400 without E-cores couldn’t care less. With DDR5 there is the tie to the Ryzen 5, with DDR4 the Core i5-12400 is even faster.
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. And the winner is the little ADL.
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. That’s exactly what you see on the bars then, with Alder Lake generally having an advantage. Unfortunately, the Ryzen 5 5600X also feels this very clearly.
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 real cores (more are not utilized) are apparently more than a mixture of P-cores and E-cores and thus the Ryzen 9 5900X wins. The strong performance of the Core i5-12400 is quite remarkable, because it surely loses compared to the i5-12600K only because of the lower clock speed. The e-cores don’t matter here either. DDR4 once again before DDR5, who would have thought…
