Ryzen 5 4500U vs Ryzen 5 8640HS comparison

According to the hardwareDB Benchmark tool, the Ryzen 5 8640HS is faster than the Ryzen 5 4500U. Furthermore, our gaming benchmark shows that it also outperforms the Ryzen 5 4500U in all gaming tests too.

Our spec comparison shows that they have an identical amount of cores but the Ryzen 5 8640HS has more threads. With our hardware info, we find that the Ryzen 5 8640HS has a significantly higher clock speed than the Ryzen 5 4500U. Also, the Ryzen 5 8640HS has a slightly higher turbo speed. A Ryzen 5 4500U CPU outputs less heat than a Ryzen 5 8640HS CPU because of its significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. The info from our database shows that the Ryzen 5 8640HS has more L2 cache than the Ryzen 5 4500U. The Ryzen 5 8640HS also has significantly more 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. For instance, the Ryzen 5 4500U has the same number of threads as cores. This means the the CPU does not support hyperthreading.
