Intel Core i5-9400 vs Intel Xeon E5-2673 v3

Core i5-9400 vs Xeon E5-2673 v3 benchmarks

In our benchmarks, the Xeon E5-2673 v3 beats the Core i5-9400 in overall performance. Despite this, the Core i5-9400 has the advantage in our gaming benchmark.

When comparing core counts for these CPUs, we notice that the Xeon E5-2673 v3 has significantly more cores with 12 cores compared to the Core i5-9400 that has 6 cores. It also has more threads than the Core i5-9400. A Core i5-9400 CPU outputs less heat than a Xeon E5-2673 v3 CPU because of its significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.

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. For instance, the Core i5-9400 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
