Core i3-8350K vs Core Ultra 7 255H benchmarks

In our benchmarks, the Core i3-8350K beats the Core Ultra 7 255H in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Core Ultra 7 255H in all gaming tests too.

When comparing core counts for these CPUs, we notice that the Core Ultra 7 255H has significantly more cores with 16 cores compared to the Core i3-8350K that has 4 cores. It also has more threads than the Core i3-8350K. Our comparison shows that the Core i3-8350K has a significantly higher clock speed compared to the Core Ultra 7 255H. In terms of cache, the Core Ultra 7 255H has significantly more L2 cache when compared to the Core i3-8350K. The Core Ultra 7 255H also has significantly more L3 cache.

The more cores a CPU has, the better the overall performance will be in parallel workloads such as multitasking. Many CPUs have more threads than cores, this means that each physical core is split into multiple logical cores, making them more efficient. For instance, the Core i3-8350K has the same number of threads as cores. This means the the CPU does not support hyperthreading.
