Ryzen 9 7945HX3D vs Ryzen 9 9955HX specs and performance

According to the hardwareDB Benchmark tool, the Ryzen 9 7945HX3D is faster than the Ryzen 9 9955HX. Despite this, the Ryzen 9 9955HX has the advantage in our gaming benchmark.

Info from our database shows that they both have the same core count and the same number of threads. These CPUs have different clock speeds. Indeed, the Ryzen 9 9955HX has a slightly higher clock speed compared to the Ryzen 9 7945HX3D. Furthermore, both these CPUs have identical turbo speeds. 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. The Ryzen 9 7945HX3D 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 7945HX3D has more threads than cores. Each physical core is split into multiple threads.
