Intel Xeon X5680 vs Intel Core Ultra 7 155U

Xeon X5680 vs Core Ultra 7 155U comparison

Our benchmark analysis concludes that the Core Ultra 7 155U performs better than the Xeon X5680. Furthermore, our gaming benchmark shows that it also outperforms the Xeon X5680 in all gaming tests too.

When comparing core counts for these CPUs, we notice that the Core Ultra 7 155U has significantly more cores with 12 cores compared to the Xeon X5680 that has 6 cores. It also has more threads than the Xeon X5680. These CPUs have different clock speeds. Indeed, the Xeon X5680 has a significantly higher clock speed compared to the Core Ultra 7 155U. Despite this, the Core Ultra 7 155U has a slightly higher turbo speed. In terms of cache, the Core Ultra 7 155U has significantly more L2 cache when compared to the Xeon X5680. The Core Ultra 7 155U 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 Xeon X5680 has more threads than cores. Each physical core is split into multiple threads.
