Intel Core i3-4005U vs AMD A9-9420

Core i3-4005U vs A9-9420 benchmarks

Our benchmark analysis concludes that the A9-9420 performs better than the Core i3-4005U. Furthermore, our gaming benchmark shows that it also outperforms the Core i3-4005U in all gaming tests too.

When comparing these CPUs we notice that they have the same number of cores but the Core i3-4005U has more threads. With our hardware info, we find that the A9-9420 has a significantly higher clock speed than the Core i3-4005U. Both these chips have an identical TDP (Thermal Design Power). 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 i3-4005U has more threads than cores. Each physical core is split into multiple threads.
