Core i5-8259U vs Core i5-8265U specs and performance

According to the hardwareDB Benchmark tool, the Core i5-8259U is faster than the Core i5-8265U. Furthermore, our gaming benchmark shows that it also outperforms the Core i5-8265U in all gaming tests too.

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 Core i5-8259U has a significantly higher clock speed compared to the Core i5-8265U. Despite this, the Core i5-8265U has a slightly higher turbo speed. The Core i5-8265U outputs less heat than Core i5-8259U thanks to a significantly lower TDP. 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 and 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 Core i5-8259U has more threads than cores. Each physical core is split into multiple threads.
