Core i7-8557U vs Xeon E5-2658 v3 comparison

In our benchmarks, the Core i7-8557U beats the Xeon E5-2658 v3 in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Xeon E5-2658 v3 in all gaming tests too.

With info from our database, we find that the Xeon E5-2658 v3 has significantly more cores with 12 cores whereas the Core i7-8557U has 4 cores. It also has more threads than the Core i7-8557U. With our hardware info, we find that the Xeon E5-2658 v3 has a slightly higher clock speed than the Core i7-8557U. Despite this, the Core i7-8557U has a significantly higher turbo speed. A Core i7-8557U CPU outputs less heat than a Xeon E5-2658 v3 CPU because of its significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.

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 i7-8557U has more threads than cores. Each physical core is split into multiple threads.
