Atom D2550 vs Core 2 Duo E6550 specs and performance

According to the hardwareDB Benchmark tool, the Core 2 Duo E6550 is faster than the Atom D2550. Furthermore, our gaming benchmark shows that it also outperforms the Atom D2550 in all gaming tests too.

Info from our database shows that they both have the same core count but the Atom D2550 has more threads. These CPUs have different clock speeds. Indeed, the Core 2 Duo E6550 has a slightly higher clock speed compared to the Atom D2550. A Atom D2550 CPU outputs less heat than a Core 2 Duo E6550 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 E6550 has significantly more L2 cache than the Atom D2550

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 Atom D2550 has more threads than cores. Each physical core is split into multiple threads.
