Intel Core i3-8350K vs Intel Core i5-8259U

Core i3-8350K vs Core i5-8259U benchmarks

Our benchmark analysis concludes that the Core i3-8350K performs better than the Core i5-8259U. Furthermore, our gaming benchmark shows that it also outperforms the Core i5-8259U in all gaming tests too.

Info from our database shows that they both have the same core count but the Core i5-8259U has more threads. Our comparison shows that the Core i3-8350K has a significantly higher clock speed compared to the Core i5-8259U. The Core i5-8259U outputs less heat than Core i3-8350K thanks to a significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. When comparing cache sizes, these CPUs have an identical amount of L2 cache. The Core i3-8350K also has slightly more 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. For instance, the Core i3-8350K has the same number of threads as cores. This means the the CPU does not support hyperthreading.
