We already tested the Ryzen 7 1700X, the Ryzen 7 1700, and the Ryzen 5 1600X. In all of those tests, we concluded that they are CPUs with high performance in applications that use paralelism (which means they can use all the threads of the CPU,) but they cannot achieve the same performance that their direct competitor in games.
With the Ryzen 5 1500X, the story wasn’t different: compared to the Core i5-7400, that costs the same, it is faster (or similar) in most of the applications, but a little slower in games. Note, however, that the difference was relatively small (except on Rise of the Tomb Raider, which seems to be unfriendly to the Zen architecture) and that the Ryzen 5 1500x don’t become a bottleneck in any test, which means it is indeed a good option for a budget gaming setup: its competitor only offers a slightly better cost/benefit ratio.
However, we have to kee in mind its good multitasking performance, which may favor, for example, recording or live broadcasting of your matches. It is also important to keep in mind that it is capable of a reasonable overclocking.
So, the Ryzen 5 1500X is a good CPU with a great cost/benefit ratio, and it is a good choice in the case you prefer the AMD platform.
