Ryzen 9 5900HX vs Ryzen 5 6600H specs and performance

According to the hardwareDB Benchmark tool, the Ryzen 9 5900HX is faster than the Ryzen 5 6600H. Furthermore, our gaming benchmark shows that it also outperforms the Ryzen 5 6600H in all gaming tests too.

With info from our database, we find that the Ryzen 9 5900HX has slightly more cores with 8 cores whereas the Ryzen 5 6600H has 6 cores. It also has more threads than the Ryzen 5 6600H. With our hardware info, we find that the Ryzen 5 6600H has a slightly higher clock speed than the Ryzen 9 5900HX. Despite this, the Ryzen 9 5900HX 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 cache sizes of these CPUs are different. Indeed, the Ryzen 9 5900HX has slightly more L2 cache than the Ryzen 5 6600H. However, both these chips have the same amount of L3 cache.

The more cores a CPU has, the better the overall performance will be in parallel workloads such as multitasking. Many CPUs have more threads than cores, this means that each physical core is split into multiple logical cores, making them more efficient. Indeed, the Ryzen 9 5900HX has more threads than cores. Each physical core is split into multiple threads.
