Intel Core i3-7350K vs Intel Core i5-8265U

Core i3-7350K vs Core i5-8265U benchmarks

Our benchmark analysis concludes that the Core i5-8265U performs better than the Core i3-7350K. Furthermore, our gaming benchmark shows that it also outperforms the Core i3-7350K in all gaming tests too.

When comparing core counts for these CPUs, we notice that the Core i5-8265U has significantly more cores with 4 cores compared to the Core i3-7350K that has 2 cores. It also has more threads than the Core i3-7350K. With our hardware info, we find that the Core i3-7350K has a significantly higher clock speed than the Core i5-8265U. The Core i5-8265U outputs less heat than Core i3-7350K thanks to a 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 Core i5-8265U has significantly more L2 cache than the Core i3-7350K. The Core i5-8265U also has significantly 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 Core i3-7350K has more threads than cores. Each physical core is split into multiple threads.
