Intel Core i5-9400T vs Intel Xeon E3-1270 v3

Core i5-9400T vs Xeon E3-1270 v3 benchmarks

In our benchmarks, the Xeon E3-1270 v3 beats the Core i5-9400T in overall performance. Despite this, the Core i5-9400T has the advantage in our gaming benchmark.

In terms of the number of cores of each of these CPUs, the Core i5-9400T has significantly more cores than the Xeon E3-1270 v3. Indeed, the Core i5-9400T has 6 cores compared to 4 cores found in the Xeon E3-1270 v3. Despite this, the Xeon E3-1270 v3 has more threads than the Core i5-9400T. These CPUs have different clock speeds. Indeed, the Xeon E3-1270 v3 has a significantly higher clock speed compared to the Core i5-9400T. Also, the Xeon E3-1270 v3 has a slightly higher turbo speed. A Core i5-9400T CPU outputs less heat than a Xeon E3-1270 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 i5-9400T has the same number of threads as cores. This means the the CPU does not support hyperthreading.
