Ryzen 7 5800U vs Core i5-10400 benchmarks

In our benchmarks, the Ryzen 7 5800U beats the Core i5-10400 in overall performance. Despite this, the Core i5-10400 has the advantage in our gaming benchmark.

In terms of the number of cores of each of these CPUs, the Ryzen 7 5800U has slightly more cores than the Core i5-10400. Indeed, the Ryzen 7 5800U has 8 cores compared to 6 cores found in the Core i5-10400. It also has more threads than the Core i5-10400. Our comparison shows that the Core i5-10400 has a significantly higher clock speed compared to the Ryzen 7 5800U. Despite this, the Ryzen 7 5800U has a slightly higher turbo speed. A Ryzen 7 5800U CPU outputs less heat than a Core i5-10400 CPU because of its significantly lower TDP. 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 7 5800U has significantly more L2 cache than the Core i5-10400. The Ryzen 7 5800U also has slightly 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 7 5800U has more threads than cores. Each physical core is split into multiple threads.
