Ryzen 9 7900X3D vs Ryzen 9 9900X3D benchmarks

According to the hardwareDB Benchmark tool, the Ryzen 9 9900X3D is faster than the Ryzen 9 7900X3D. Furthermore, our gaming benchmark shows that it also outperforms the Ryzen 9 7900X3D in all gaming tests too.

When comparing these CPUs we notice that they have the same number of cores and the same number of threads. With our hardware info, we find that the Ryzen 9 7900X3D has a slightly higher clock speed than the Ryzen 9 9900X3D. Also, the Ryzen 9 7900X3D has a slightly higher turbo speed. Both these chips have an identical TDP (Thermal Design Power). 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.

Modern CPUs generally have more logical cores than physical cores, this means that each core is split into multiple virtual cores, improving efficiency for parallel workloads. Indeed, the Ryzen 9 7900X3D has more threads than cores. Each physical core is split into multiple threads.
