Ryzen 9 7900 vs Ryzen 9 9900X3D benchmarks
According to the hardwareDB Benchmark tool, the Ryzen 9 9900X3D 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. These CPUs have different clock speeds. Indeed, the Ryzen 9 9900X3D has a slightly higher clock speed compared to the Ryzen 9 7900. Also, the Ryzen 9 9900X3D has a slightly higher turbo speed. A Ryzen 9 7900 CPU outputs less heat than a Ryzen 9 9900X3D CPU because of its significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. In terms of cache, both these CPUs have the same amount of L2 cache. The Ryzen 9 9900X3D 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 7900 has more threads than cores. Each physical core is split into multiple threads.
