CPU Performance: Workstation
Of course, in the production area, not only 3D graphics performance is important in the application, because many things are calculated by the CPU in parallel within these applications (simulations, compute tasks, preview rendering, etc.). In order to get a truly objective impression, you always have to look at both in context.
Many of the current software packages also contain modules based on pure calculations and simulations, so that you always have to include all possible aspects in productive use. However, software packages such as Solidworks do not fully scale with the large number of possible threads, so that often enough quad-cores with high IPC (and SMT) can exist here. This can also be seen in the direct comparison between the Core i5-7600K and the Core i5-8400K, which cannot always benefit from the higher core count and the larger cache.
At Creo, the pure clock counts as long as up to 8 threads can run stress-free. Otherwise, the new Core i5-8400 can only take small benefits from the two additional cores when looking at the core i5-7600K.
At 3ds Max, the clock and core count, whereby the Core i5-8400 can now set itself off slightly from the Core i5-7600K. However, the overclocked Ryzen 5 1600X is close to his heels.
In the CPU composite, on the other hand, extensive rendering is also included (which we will come to separately) so that the overall rating of the AMD Ryzen 5 provides a slightly different picture. The Ryzen are now the absolute measure of things in this test. A feat, because here there are 12 instead of 6 threads, as double.
CPU Performance: Photorealistic Rendering
In final rendering, it is no longer so much universality that matters, but the most efficient and fast, parallelized processing. That's why we're looking at this section now. So let's get back to 3ds Max right at the beginning. In pure rendering, the Core i7-8400 in its class only makes the Ryzen 5 1600 a thing of the present if it is overclocked. Core count goes ahead with clock, although the performance with the latter also scales beautifully.
The console version of Luxrender confirms this image, whereby none of the Core i5 can compete with the Ryzen 5 1600X. The new Core i5 simply no longer sees land and the hyper-threading of the Core i7 is missing at all corners and edges.
Let us now turn to Blender. The usual workload (but with a sample size of 200 pixels) confirms the image of the previous tests very impressively. The Core i7-8400 is still behind the Ryzen 5 1600X, unclocked.
If we run the blender loop of the SPECwpc, the result looks very similar, even if the task is somewhat different. Ryzen 5 before Core i5.
If the share of pure rendering power continues to decrease, the non-overclocked Core i5-8600 will also move upwards. But the rest looks like it was back and the Core i5-8400 is also lagnitating due to lack of HT.
This becomes even clearer with the changing task and suitability of the respective CPUs, if one does not limit oneanother to photorealistic image output, but also plays a role in the loop, in which not only the core number of decisive factor, but also the IPC. The Core i5-8600K even takes the lead, followed by the Core i5-8400.
In this part, the Ryzen 5 1600X pushes itself back to the top, because the core and thread numbers are not unimportant.
Intermediate conclusion
Intel's Core i7-8400 is certainly useful in semi-professional use and not just in gaming. However, the Core i5 lacks hyper-threading at all corners and edges when it comes to parallelizable tasks. This throws the actually potent six-nucleus back exactly where Intel probably likes it with the current pricing policy. AMD thanks in many benchmarks with the dominance of the Ryzen 5 1600X in computing and rendering. The Ryzen 5 1500X suffers a bit of the fate of Intel's Core i5 due to the lack of cores/threads.
