Intel Core i5-9400T vs Intel Xeon E3-1280 v3

Core i5-9400T vs Xeon E3-1280 v3 specs and performance

In our benchmarks, the Core i5-9400T beats the Xeon E3-1280 v3 in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Xeon E3-1280 v3 in all gaming tests too.

In terms of the number of cores of each of these CPUs, the Core i5-9400T has significantly more cores than the Xeon E3-1280 v3. Indeed, the Core i5-9400T has 6 cores compared to 4 cores found in the Xeon E3-1280 v3. Despite this, the Xeon E3-1280 v3 has more threads than the Core i5-9400T. Our comparison shows that the Xeon E3-1280 v3 has a significantly higher clock speed compared to the Core i5-9400T. Also, the Xeon E3-1280 v3 has a slightly higher turbo speed. A Core i5-9400T CPU outputs less heat than a Xeon E3-1280 v3 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.
