Core m3-6Y30 vs Core 2 Duo T6400 comparison

Our benchmark analysis concludes that the Core m3-6Y30 performs better than the Core 2 Duo T6400. Despite this, the Core 2 Duo T6400 has the advantage in our gaming benchmark.

Our spec comparison shows that they have an identical amount of cores but the Core m3-6Y30 has more threads. With our hardware info, we find that the Core 2 Duo T6400 has a slightly higher clock speed than the Core m3-6Y30. A Core m3-6Y30 CPU outputs less heat than a Core 2 Duo T6400 CPU because of its significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. The cache sizes of these CPUs are different. Indeed, the Core 2 Duo T6400 has significantly more L2 cache than the Core m3-6Y30

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 m3-6Y30 has more threads than cores. Each physical core is split into multiple threads.
