Intel Core i7-1255U vs Intel Xeon X5675

Core i7-1255U vs Xeon X5675 specs and performance

According to the hardwareDB Benchmark tool, the Xeon X5675 is faster than the Core i7-1255U. Despite this, the Core i7-1255U has the advantage in our gaming benchmark.

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 X5675 that has 6 cores. But they both have the same number of threads. With our hardware info, we find that the Xeon X5675 has a significantly higher clock speed than 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 X5675 CPU because of its significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. The info from our database shows that the Core i7-1255U has more L2 cache than the Xeon X5675. 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.
