AMD Ryzen 9 9900X in a megatest of 40 CPUs

Average processor power draw

We’re wrapping up tests of the new Ryzen 9000 desktop CPUs. This with a model that once increased the number of cores compared to its predecessor, or a pilot model (Ryzen 9 3900X) from eight to twelve on AMD’s mainstream platform. Even compared to the Ryzen 9 5900X, the new Ryzen 9 9900X is more than twice as fast in some practical situations. This model is also the best when it comes to efficiency.

Disclaimer: For big.LITTLE-based processors, the result is missing in some tests. This is because they didn’t scale properly with P cores and the achieved performance was too low. In such cases it is indeed possible to force performance on all cores, but this does not happen by default at the user level. To avoid creating the illusion in some cases that measured results such as those presented in the graphs are normally achieved, we omit them. However, these are a negligible fraction of the total set of test results.

  1. I am wondering what is going on with certain tests where 9900x is inferior to 7900x. In particular, AIDA64 FPU Julia and Mandel. For instance, in Julia test 9900x only achieves 28% of 7900x’s performance…!? Does it have something to do with test versions (7900x was tested almost 2 years ago).

    This also makes me to ask if there is a way to tell which cases are actually comparable? Is it possible to select only the exact same versions?

    1. I assume that this is a consequence of non-optimization of the application (in this case Aida64) for given tests with specific processors, or rather their architectures.
