Intel Core i5-11400 vs Intel Core i5-8250U

Core i5-11400 vs Core i5-8250U benchmarks

According to the hardwareDB Benchmark tool, the Core i5-11400 is faster than the Core i5-8250U. Furthermore, our gaming benchmark shows that it also outperforms the Core i5-8250U in all gaming tests too.

When comparing core counts for these CPUs, we notice that the Core i5-11400 has significantly more cores with 6 cores compared to the Core i5-8250U that has 4 cores. It also has more threads than the Core i5-8250U. Our comparison shows that the Core i5-11400 has a significantly higher clock speed compared to the Core i5-8250U. Also, the Core i5-11400 has a slightly higher turbo speed. The Core i5-8250U outputs less heat than Core i5-11400 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 i5-11400 has significantly more L2 cache than the Core i5-8250U. The Core i5-11400 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 i5-11400 has more threads than cores. Each physical core is split into multiple threads.
