Core i7-6700T vs Xeon X5647 specs and performance

According to the hardwareDB Benchmark tool, the Xeon X5647 is faster than the Core i7-6700T. Despite this, the Core i7-6700T has the advantage in our gaming benchmark.

Info from our database shows that they both have the same core count and the same number of threads. These CPUs have different clock speeds. Indeed, the Xeon X5647 has a slightly higher clock speed compared to the Core i7-6700T. Despite this, the Core i7-6700T has a slightly higher turbo speed. A Core i7-6700T CPU outputs less heat than a Xeon X5647 CPU because of its significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. The data shows that both these CPUs have same sized L2 caches. The Xeon X5647 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 Core i7-6700T has more threads than cores. Each physical core is split into multiple threads.
