Intel Core i5-11400 vs Intel Core i5-9400

Core i5-11400 vs Core i5-9400 comparison

In our benchmarks, the Core i5-11400 beats the Core i5-9400 in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Core i5-9400 in all gaming tests too.

Our spec comparison shows that they have an identical amount of cores but the Core i5-11400 has more threads. With our hardware info, we find that the Core i5-11400 has a slightly higher clock speed than the Core i5-9400. Also, the Core i5-11400 has a slightly higher turbo speed. 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. In terms of cache, the Core i5-11400 has significantly more L2 cache when compared to the Core i5-9400. The Core i5-11400 also has slightly more L3 cache.

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 i5-11400 has more threads than cores. Each physical core is split into multiple threads.
