Core i5-6400 vs Core 2 Duo E8500 specs and performance

In our benchmarks, the Core i5-6400 beats the Core 2 Duo E8500 in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Core 2 Duo E8500 in all gaming tests too.

In terms of the number of cores of each of these CPUs, the Core i5-6400 has significantly more cores than the Core 2 Duo E8500. Indeed, the Core i5-6400 has 4 cores compared to 2 cores found in the Core 2 Duo E8500. It also has more threads than the Core 2 Duo E8500. These CPUs have different clock speeds. Indeed, the Core 2 Duo E8500 has a slightly higher clock speed compared to the Core i5-6400. Both these chips have an identical TDP (Thermal Design Power). 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 E8500 has more L2 cache than the Core i5-6400

Modern CPUs generally have more logical cores than physical cores, this means that each core is split into multiple virtual cores, improving efficiency for parallel workloads. For instance, the Core i5-6400 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
