Intel Xeon E3-1505M v6 vs Intel Core i7-1260U

Xeon E3-1505M v6 vs Core i7-1260U specs and performance

Our benchmark analysis concludes that the Xeon E3-1505M v6 performs better than the Core i7-1260U. Despite this, the Core i7-1260U has the advantage in our gaming benchmark.

When comparing core counts for these CPUs, we notice that the Core i7-1260U has significantly more cores with 10 cores compared to the Xeon E3-1505M v6 that has 4 cores. It also has more threads than the Xeon E3-1505M v6. With our hardware info, we find that the Xeon E3-1505M v6 has a significantly higher clock speed than the Core i7-1260U. Despite this, the Core i7-1260U has a slightly higher turbo speed. The Core i7-1260U outputs less heat than Xeon E3-1505M v6 thanks to a significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. In terms of cache, the Core i7-1260U has significantly more L2 cache when compared to the Xeon E3-1505M v6. The Core i7-1260U 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 E3-1505M v6 has more threads than cores. Each physical core is split into multiple threads.
