Rendering with Cinebench, Blender and LuxRender
Even though I don’t really like it because the Cinebench R23 delivers rather inconsistent results, you can of course still make a correct statement in total. The performance of the Ryzen 9 7950X is beyond discussion and speaks for itself. The Ryzen 7 7700X can also set itself apart from the older AMD models more clearly than expected.
The single-thread performance logically shows the expected picture, even though the advantage over Intel’s Alder Lake is not as big. Raptor Lake could very well pass here.
It’s the same as always, of course: a good renderer needs invigorating core feed, it always has. My beloved igoBOT is a grateful task there, even if rendering on the CPU is slowly going out of fashion. But before I take things like Cinebench as the sole benchmark, I’d rather run something like that, which also sometimes causes a few minutes of work and delivers very consistent results. And it can also heat.
Once again, we see the Ryzen 9 7950X ramming and rendering virtually everything into the ground that didn’t make it to Three on the Trees. The smaller new CPU also clearly shows the predecessor the back of its hand.
The Luxmark as a decoupling of the LuxRender suite shows a very similar positioning of both new Ryzen CPUs in the score.
LTspiceXVII
New in my benchmark suite is LTspiceXVII, circuit simulation program. The simulator is designed to run industry standard semiconductor and behavioral models. New circuits can be designed with the integrated schematic capture. Simulation commands and parameters are placed as text on the schematic using common SPICE syntax. Waveforms of circuit nodes and device currents can be recorded by mouse click on the nodes in the schematic during or after simulation.
My thanks here go to our forum member Deridex, who contributed the workload as well as the idea. A total of 16 threads are used in the benchmark, which naturally makes the CPUs with 8 cores and more slip closer together at the top.
Encoding, financial service and programming
The first two benchmarks also benefit many cores again, with FSI being pure compute. However, since the Ryzen 7 7700X CPU only has 8 cores, it consequently has to place itself in the middle, exactly on par with the Intel Core i7-12700K in Handbrake, which it can then even beat slightly in FSI.
In Python and even more so Octave, Intel used to be the measure of all things, now they are no longer. Python, like Math Lab, relies on Intel’s Math Kernel Library (MKL) in many areas. NumPy in particular suffered a bit here in the past. The Ryzen 9 7950X now becomes the terminator here and the smaller Ryzen 7 7700X even beats the Ryzen 9 5950X, albeit narrowly.
The next workload uses Octave, a programming language for scientific computing, to solve a variety of mathematical operations. The differences between the bar lengths of the CPUs turn out to be much smaller, but especially the Ryzen 7 7700X benefits from clock and even moves up to third place.
