Core i5-12400F vs Core i5-3450 specs and performance
Our benchmark analysis concludes that the Core i5-12400F performs better than the Core i5-3450. Furthermore, our gaming benchmark shows that it also outperforms the Core i5-3450 in all gaming tests too.
When comparing core counts for these CPUs, we notice that the Core i5-12400F has significantly more cores with 6 cores compared to the Core i5-3450 that has 4 cores. It also has more threads than the Core i5-3450. These CPUs have different clock speeds. Indeed, the Core i5-3450 has a slightly higher clock speed compared to the Core i5-12400F. Despite this, the Core i5-12400F has a slightly higher turbo speed. A Core i5-12400F CPU outputs less heat than a Core i5-3450 CPU because of its slightly lower TDP. 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 i5-12400F has more threads than cores. Each physical core is split into multiple threads.
