Ryzen 7 1800X vs Ryzen 5 7640HS specs and performance

Our benchmark analysis concludes that the Ryzen 7 1800X performs better than the Ryzen 5 7640HS. Despite this, the Ryzen 5 7640HS has the advantage in our gaming benchmark.

When comparing core counts for these CPUs, we notice that the Ryzen 7 1800X has slightly more cores with 8 cores compared to the Ryzen 5 7640HS that has 6 cores. It also has more threads than the Ryzen 5 7640HS. With our hardware info, we find that the Ryzen 5 7640HS has a slightly higher clock speed than the Ryzen 7 1800X. Also, the Ryzen 5 7640HS has a slightly higher turbo speed. The Ryzen 5 7640HS outputs less heat than Ryzen 7 1800X thanks to a 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 7640HS has more L2 cache than the Ryzen 7 1800X. However, both these chips have the same amount of 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 7 1800X has more threads than cores. Each physical core is split into multiple threads.
