Intel Core i3-4030U vs Intel Core 2 Duo E8400

Core i3-4030U vs Core 2 Duo E8400 comparison

According to the hardwareDB Benchmark tool, the Core 2 Duo E8400 is faster than the Core i3-4030U. Furthermore, our gaming benchmark shows that it also outperforms the Core i3-4030U in all gaming tests too.

Our spec comparison shows that they have an identical amount of cores but the Core i3-4030U has more threads. These CPUs have different clock speeds. Indeed, the Core 2 Duo E8400 has a significantly higher clock speed compared to the Core i3-4030U. A Core i3-4030U CPU outputs less heat than a Core 2 Duo E8400 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. Indeed, the Core i3-4030U has more threads than cores. Each physical core is split into multiple threads.
