Core 2 Duo E7400 vs Core 2 Duo T6400 comparison

Our benchmark analysis concludes that the Core 2 Duo T6400 performs better than the Core 2 Duo E7400. Furthermore, our gaming benchmark shows that it also outperforms the Core 2 Duo E7400 in all gaming tests too.

Our spec comparison shows that they have an identical amount of cores and the same number of threads. Our comparison shows that the Core 2 Duo E7400 has a slightly higher clock speed compared to the Core 2 Duo T6400. The Core 2 Duo T6400 outputs less heat than Core 2 Duo E7400 thanks to a significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. The info from our database shows that the Core 2 Duo E7400 has more L2 cache than the Core 2 Duo T6400

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 2 Duo E7400 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
