Intel Xeon X5680 vs Intel Core Ultra 7 155U

Xeon X5680 vs Core Ultra 7 155U comparison

Our benchmark analysis concludes that the Xeon X5680 performs better than the Core Ultra 7 155U. Despite this, the Core Ultra 7 155U has the advantage in our gaming benchmark.

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. 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.
