Rendering with Cinebench, Blender and LuxRender
Even though I actually don’t like it, because the Cinebench R23 delivers rather inconsistent results, in total you can of course still make a correct statement. The Ryzen 9 7950X’s performance in rendering is beyond discussion and speaks for AMD, but it is beaten by the Intel Core i9-14900K for the first time. Furthermore, the Intel Core i9-13900K is only very close behind. However, I refuse to flood the CPU with up to 350 watts and more (I reached over 450 watts with Chiller!), just in case it might still be ahead. That would be energetic mischief of the extra class, especially since you could also give the Ryzen 9 even more power. And thus AMD now has to endure an Intel sandwich.
The single-thread performance logically shows the expected picture again, especially since the advantage over Intel’s older Raptor Lake is visible here. The small Core i5-14600K is quite well positioned, also in terms of efficiency.
Of course, it is as always: A good renderer needs powerful core fodder, that has always been the case. My beloved igoBOT is a thankful task there, even if rendering on the CPU is slowly going out of fashion. But before I take things like Cinebench as my sole benchmark, I’d rather run something like that, which sometimes causes a few minutes of work and delivers very consistent results. And it can also heat up.
We once again see the Ryzen 9 7950X, which has so far effectively run everything into the ground that did not save itself until Three on the Trees. And yet it once again has to admit defeat to the Core i9-14900K and, as already in Cinebench R23, the Core i9-13900K is only just behind it. But we’ll soon see what this means in the socket. Also in the dark.
The LuxMark, which is an offshoot of the LuxRender suite, shows a very similar positioning in the score, whereby the Ryzen 9 7950X can overtake Intel’s new flagship. The rest is sorted according to industry standards, including the CPUs with 3D cache.
LTspiceXVII
New to my benchmark suite is LTspiceXVII, a circuit simulation program. The simulator is designed to run industry-standard semiconductor and behavioral models. New circuits can be designed using the integrated schematic capture feature. 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 clicking on the nodes in the schematic during or after simulation.
My thanks here again 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 or more slip closer together at the top. Nevertheless, the Core i9-14900K beats all the rest, including the predecessors and the fat Ryzen 9, which leads the chasers.
Encoding, Financial Service and Programming
The first two benchmarks again benefit many cores, with FSI being pure compute. This is still AMD’s domain, especially since Intel performs weaker overall in FSI than in Handbrake.
In Python and even more so Octave, Intel is again the measure of all things, even though the Ryzen 9 7950X was in the lead for a while. Now it is no longer. Python, like Math Lab, relies on Intel’s Math Kernel Library (MKL) in many areas. Especially in NumPy, AMD CPUs suffered a bit here in the past. However, the Core i9-14900K is now becoming the new Terminator here and the rest follows the usual trend.
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 two Core i9s benefit from clock across the cores and push themselves far ahead of all other CPUs.
