Ryzen 9 7845HX vs Ryzen 9 7900 comparison
According to the hardwareDB Benchmark tool, the Ryzen 9 7845HX 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.
When comparing these CPUs we notice that they have the same number of cores and the same number of threads. These CPUs have different clock speeds. Indeed, the Ryzen 9 7900 has a slightly higher clock speed compared to the Ryzen 9 7845HX. Also, the Ryzen 9 7900 has a slightly higher turbo speed. A Ryzen 9 7845HX CPU outputs less heat than a Ryzen 9 7900 CPU because of its slightly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. When comparing cache sizes, these CPUs have an identical amount of L2 cache 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 7845HX has more threads than cores. Each physical core is split into multiple threads.
