Core i7-8705G vs Xeon X5647 specs and performance

In our benchmarks, the Core i7-8705G beats the Xeon X5647 in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Xeon X5647 in all gaming tests too.

Info from our database shows that they both have the same core count and the same number of threads. Our comparison shows that the Core i7-8705G has a slightly higher clock speed compared to the Xeon X5647. Also, the Core i7-8705G has a slightly higher turbo speed. A Core i7-8705G 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. In terms of cache, both these CPUs have the same amount of L2 cache. The Xeon X5647 also has significantly more L3 cache.

Modern CPUs generally have more logical cores than physical cores, this means that each core is split into multiple virtual cores, improving efficiency for parallel workloads. Indeed, the Core i7-8705G has more threads than cores. Each physical core is split into multiple threads.
