Core i5-9400T vs Xeon E5-2643 comparison

In our benchmarks, the Xeon E5-2643 beats the Core i5-9400T in overall performance. Despite this, the Core i5-9400T has the advantage in our gaming benchmark.

With info from our database, we find that the Core i5-9400T has significantly more cores with 6 cores whereas the Xeon E5-2643 has 4 cores. Despite this, the Xeon E5-2643 has more threads than the Core i5-9400T. Our comparison shows that the Xeon E5-2643 has a significantly higher clock speed compared to the Core i5-9400T. Also, the Xeon E5-2643 has a slightly higher turbo speed. A Core i5-9400T CPU outputs less heat than a Xeon E5-2643 CPU because of its significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.

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 i5-9400T has the same number of threads as cores. This means the the CPU does not support hyperthreading.
