Intel Core i7-1255U vs Intel Xeon X5670

Core i7-1255U vs Xeon X5670 comparison

In our benchmarks, the Core i7-1255U beats the Xeon X5670 in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Xeon X5670 in all gaming tests too.

When comparing core counts for these CPUs, we notice that the Core i7-1255U has significantly more cores with 10 cores compared to the Xeon X5670 that has 6 cores. But they both have the same number of threads. These CPUs have different clock speeds. Indeed, the Xeon X5670 has a significantly higher clock speed compared to the Core i7-1255U. Despite this, the Core i7-1255U has a slightly higher turbo speed. A Core i7-1255U CPU outputs less heat than a Xeon X5670 CPU because of its significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. The cache sizes of these CPUs are different. Indeed, the Core i7-1255U has significantly more L2 cache than the Xeon X5670. However, both these chips have the same amount of 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 Core i7-1255U has more threads than cores. Each physical core is split into multiple threads.
