Intel Core i5-9400T vs Intel Xeon E5-2640

Core i5-9400T vs Xeon E5-2640 benchmarks

In our benchmarks, the Core i5-9400T beats the Xeon E5-2640 in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Xeon E5-2640 in all gaming tests too.

When comparing these CPUs we notice that they have the same number of cores but the Xeon E5-2640 has more threads. These CPUs have different clock speeds. Indeed, the Xeon E5-2640 has a slightly higher clock speed compared to the Core i5-9400T. Despite this, the Core i5-9400T has a slightly higher turbo speed. A Core i5-9400T CPU outputs less heat than a Xeon E5-2640 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 E5-2640 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. For instance, the Core i5-9400T has the same number of threads as cores. This means the the CPU does not support hyperthreading.
