Intel Xeon W-11855M vs Intel Core Ultra 5 135U

Xeon W-11855M vs Core Ultra 5 135U benchmarks

In our benchmarks, the Xeon W-11855M beats the Core Ultra 5 135U in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Core Ultra 5 135U in all gaming tests too.

When comparing core counts for these CPUs, we notice that the Core Ultra 5 135U has significantly more cores with 12 cores compared to the Xeon W-11855M that has 6 cores. It also has more threads than the Xeon W-11855M. These CPUs have different clock speeds. Indeed, the Xeon W-11855M has a significantly higher clock speed compared to the Core Ultra 5 135U. Also, the Xeon W-11855M has a slightly higher turbo speed.

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 Xeon W-11855M has more threads than cores. Each physical core is split into multiple threads.
