AMD Ryzen 9 5900X Performance & Tests

The AMD Ryzen 9 5900X is, by a wide margin, the fastest processor we’ve ever evaluated on a mainstream platform. The Ryzen 9 5900X greatly outperformed not only its predecessor, the Ryzen 9 3900X, but also its major rival, the Intel Core i9-10900K, in all but one of our tests.

This time, we concentrated our testing on the top PC games available because AMD is now emphasizing that use-case, and for good reason.

AMD Ryzen 9 5900X 3

The AMD Ryzen 9 5900X outperforms the Intel Core i9-10900K by 8% in Assassins Creed Odyssey, the game with the highest CPU load in our test suite. This results in a frame rate increase exceeding 80 fps. But in this test, it is roughly on par with the AMD Ryzen 9 3900X.

However, the AMD Ryzen 9 5900X deviates more from Intel processors in Total War: Three Kingdoms, a title that has always favored Intel processors. When playing this game at 1080p with the Ultra quality level, the AMD Ryzen 9 5900X averages 116 frames per second, outpacing the Intel Core i9-10900108 K’s frames per second. There is also a 7% difference there.

The Time Spy physics test is the one area where Intel has an advantage. Instead of reporting the overall score for this test, we only consider the CPU score. In comparison to Intel’s 13,888 points, the Ryzen 9 5900X earns 12,885 points. That turns the tables in that synthetic gaming task, giving Intel a 7% advantage. What’s remarkable is that it has already caught up to the Ryzen 9 3950X, the top model from the previous generation.

Now that we’ve moved on to CPU-only workloads, it should come as no surprise that the Ryzen 9 5900X destroys the Core i9-10900K in multi-core workloads, but the same was true of the Ryzen 9 3900X. However, the Ryzen 9 5900X now outperforms the Intel Core i9-10900K by 24% in the GeekBench 5 multi-core test, up from the Ryzen 9 3900X’s 11% advantage.

The multi-core lead jumps to a huge 31% in Cinebench R20, which simulates rendering for creative applications. The Ryzen 9 5900X has the smallest advantage in terms of pure CPU performance; it is only 18% quicker on the SISoft Sandra CPU Arithmetic test, but that advantage is still sizable.

AMD Ryzen 9 5900X 4

The major development here is the substantial improvement in single-core speed made possible by the Zen 3 architecture’s complete redesign. The AMD Ryzen 9 5900X achieves a score of 618 in the Cinebench R20 single-core test, up from the Ryzen 9 3900X’s 518, representing a 19% generational improvement. In this test, the Intel Core i9-10900K earns 522 points, which is 18% less than AMD.

That pattern appears again in each of our sandbox single-core testing. In Cinebench R15 single-core, GeekBench 4, and GeekBench 5, the Intel Core i9-10900K performs 21% slower, 9% slower, and 12% slower, respectively.

Finally, AMD has reclaimed Intel’s top spot for single-core performance. Although benchmarking software clearly shows this, the way that this is represented in actual game performance is more astounding. With Zen 3, AMD sought to produce the finest processor for gaming, and according to every test we’ve conducted, Team Red has succeeded admirably.
