Core i3-8350K vs Xeon E5-2640 benchmarks

Our benchmark analysis concludes that the Core i3-8350K performs better than the Xeon E5-2640. Furthermore, our gaming benchmark shows that it also outperforms the Xeon E5-2640 in all gaming tests too.

When comparing core counts for these CPUs, we notice that the Xeon E5-2640 has significantly more cores with 6 cores compared to the Core i3-8350K that has 4 cores. It also has more threads than the Core i3-8350K. These CPUs have different clock speeds. Indeed, the Core i3-8350K has a significantly higher clock speed compared to the Xeon E5-2640. A Core i3-8350K CPU outputs less heat than a Xeon E5-2640 CPU because of its slightly 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 Xeon E5-2640 has more L2 cache than the Core i3-8350K. The Xeon E5-2640 also has significantly more L3 cache.

The more cores a CPU has, the better the overall performance will be in parallel workloads such as multitasking. Many CPUs have more threads than cores, this means that each physical core is split into multiple logical cores, making them more efficient. For instance, the Core i3-8350K has the same number of threads as cores. This means the the CPU does not support hyperthreading.
