Ryzen 9 9955HX vs Core i9-12900 comparison

According to the hardwareDB Benchmark tool, the Core i9-12900 is faster than the Ryzen 9 9955HX. Furthermore, our gaming benchmark shows that it also outperforms the Ryzen 9 9955HX in all gaming tests too.

Info from our database shows that they both have the same core count but the Ryzen 9 9955HX has more threads. These CPUs have different clock speeds. Indeed, the Ryzen 9 9955HX has a slightly higher clock speed compared to the Core i9-12900. Also, the Ryzen 9 9955HX has a slightly higher turbo speed. A Ryzen 9 9955HX CPU outputs less heat than a Core i9-12900 CPU because of its slightly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. The cache sizes of these CPUs are different. Indeed, the Ryzen 9 9955HX has slightly more L2 cache than the Core i9-12900. The Ryzen 9 9955HX also has significantly more L3 cache.

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. Indeed, the Ryzen 9 9955HX has more threads than cores. Each physical core is split into multiple threads.
