Intel Core Ultra 9 285K vs AMD Ryzen 9 9900X3D

Core Ultra 9 285K vs Ryzen 9 9900X3D benchmarks

In our benchmarks, the Core Ultra 9 285K beats the Ryzen 9 9900X3D in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Ryzen 9 9900X3D in all gaming tests too.

When comparing core counts for these CPUs, we notice that the Core Ultra 9 285K has significantly more cores with 24 cores compared to the Ryzen 9 9900X3D that has 12 cores. But they both have the same number of threads. These CPUs have different clock speeds. Indeed, the Ryzen 9 9900X3D has a slightly higher clock speed compared to the Core Ultra 9 285K. Despite this, the Core Ultra 9 285K has a slightly higher turbo speed. In terms of cache, the Core Ultra 9 285K has significantly more L2 cache when compared to the Ryzen 9 9900X3D. Despite this, the Ryzen 9 9900X3D has significantly more L3 cache compared to the Core Ultra 9 285K.

Most CPUs have more threads than cores. This technology, colloquially called hyperthreading, improves performance by splitting a core into multiple virtual ones. This provides more efficient utilisation of a core. For instance, the Core Ultra 9 285K has the same number of threads as cores. This means the the CPU does not support hyperthreading.
