Core Ultra 7 255H vs Xeon Gold 6138 benchmarks

Our benchmark analysis concludes that the Core Ultra 7 255H performs better than the Xeon Gold 6138. Furthermore, our gaming benchmark shows that it also outperforms the Xeon Gold 6138 in all gaming tests too.

With info from our database, we find that the Xeon Gold 6138 has slightly more cores with 20 cores whereas the Core Ultra 7 255H has 16 cores. It also has more threads than the Core Ultra 7 255H. These CPUs have different clock speeds. Indeed, the Core Ultra 7 255H has a slightly higher clock speed compared to the Xeon Gold 6138. Also, the Core Ultra 7 255H has a slightly higher turbo speed. The cache sizes of these CPUs are different. Indeed, the Core Ultra 7 255H has slightly more L2 cache than the Xeon Gold 6138. Despite this, the Xeon Gold 6138 has slightly more L3 cache compared to the Core Ultra 7 255H.

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 Ultra 7 255H has the same number of threads as cores. This means the the CPU does not support hyperthreading.
