A9-9420 vs Core 2 Duo E8400 comparison
According to the hardwareDB Benchmark tool, the Core 2 Duo E8400 is faster than the A9-9420. Furthermore, our gaming benchmark shows that it also outperforms the A9-9420 in all gaming tests too.
Info from our database shows that they both have the same core count and the same number of threads. In terms of clock speed, the A9-9420 and Core 2 Duo E8400 are identical in this regard. A A9-9420 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 A9-9420
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. For instance, the A9-9420 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
