Intel Core i5-8400T vs Intel Xeon E3-1231 v3

Core i5-8400T vs Xeon E3-1231 v3 benchmarks

Our benchmark analysis concludes that the Core i5-8400T performs better than the Xeon E3-1231 v3. Furthermore, our gaming benchmark shows that it also outperforms the Xeon E3-1231 v3 in all gaming tests too.

When comparing core counts for these CPUs, we notice that the Core i5-8400T has significantly more cores with 6 cores compared to the Xeon E3-1231 v3 that has 4 cores. Despite this, the Xeon E3-1231 v3 has more threads than the Core i5-8400T. These CPUs have different clock speeds. Indeed, the Xeon E3-1231 v3 has a significantly higher clock speed compared to the Core i5-8400T. Also, the Xeon E3-1231 v3 has a slightly higher turbo speed. A Core i5-8400T CPU outputs less heat than a Xeon E3-1231 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. For instance, the Core i5-8400T has the same number of threads as cores. This means the the CPU does not support hyperthreading.
