Intel Core i5-12400 vs Intel Core 2 Duo E6550

Core i5-12400 vs Core 2 Duo E6550 specs and performance

Our benchmark analysis concludes that the Core i5-12400 performs better than the Core 2 Duo E6550. Furthermore, our gaming benchmark shows that it also outperforms the Core 2 Duo E6550 in all gaming tests too.

In terms of the number of cores of each of these CPUs, the Core i5-12400 has significantly more cores than the Core 2 Duo E6550. Indeed, the Core i5-12400 has 6 cores compared to 2 cores found in the Core 2 Duo E6550. It also has more threads than the Core 2 Duo E6550. With our hardware info, we find that the Core i5-12400 has a slightly higher clock speed than the Core 2 Duo E6550. 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 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. Indeed, the Core i5-12400 has more threads than cores. Each physical core is split into multiple threads.
