Ryzen 9 7900 vs Ryzen 9 9900X benchmarks

According to the hardwareDB Benchmark tool, the Ryzen 9 9900X is faster than the Ryzen 9 7900. Furthermore, our gaming benchmark shows that it also outperforms the Ryzen 9 7900 in all gaming tests too.

Our spec comparison shows that they have an identical amount of cores and the same number of threads. Our comparison shows that the Ryzen 9 9900X has a slightly higher clock speed compared to the Ryzen 9 7900. Also, the Ryzen 9 9900X has a slightly higher turbo speed. A Ryzen 9 7900 CPU outputs less heat than a Ryzen 9 9900X CPU because of its significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. The data shows that both these CPUs have same sized L2 caches and 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 7900 has more threads than cores. Each physical core is split into multiple threads.
