Intel Pentium Silver J5040 vs Intel Core 2 Quad Q9400

Pentium Silver J5040 vs Core 2 Quad Q9400 specs and performance

In our benchmarks, the Core 2 Quad Q9400 beats the Pentium Silver J5040 in overall performance. Despite this, the Pentium Silver J5040 has the advantage in our gaming benchmark.

Our spec comparison shows that they have an identical amount of cores and the same number of threads. With our hardware info, we find that the Core 2 Quad Q9400 has a slightly higher clock speed than the Pentium Silver J5040. A Pentium Silver J5040 CPU outputs less heat than a Core 2 Quad Q9400 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 Pentium Silver J5040 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
