Core i3-5005U vs Core 2 Duo E8400 comparison
Our benchmark analysis concludes that the Core i3-5005U performs better than the Core 2 Duo E8400. Despite this, the Core 2 Duo E8400 has the advantage in our gaming benchmark.
When comparing these CPUs we notice that they have the same number of cores but the Core i3-5005U 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 i3-5005U. A Core i3-5005U 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. In terms of cache, the Core 2 Duo E8400 has significantly more L2 cache when compared to the Core i3-5005U
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 i3-5005U has more threads than cores. Each physical core is split into multiple threads.
