Intel Core i5-11400H vs Intel Xeon E5-2666 v3

Core i5-11400H vs Xeon E5-2666 v3 benchmarks

In our benchmarks, the Core i5-11400H beats the Xeon E5-2666 v3 in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Xeon E5-2666 v3 in all gaming tests too.

When comparing core counts for these CPUs, we notice that the Xeon E5-2666 v3 has significantly more cores with 10 cores compared to the Core i5-11400H that has 6 cores. It also has more threads than the Core i5-11400H. Our comparison shows that the Xeon E5-2666 v3 has a slightly higher clock speed compared to the Core i5-11400H. In terms of cache, the Core i5-11400H has significantly more L2 cache when compared to the Xeon E5-2666 v3. Despite this, the Xeon E5-2666 v3 has significantly more L3 cache compared to the Core i5-11400H.

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 i5-11400H has more threads than cores. Each physical core is split into multiple threads.
