Core i5-11400 vs Core i7-9700K comparison

According to the hardwareDB Benchmark tool, the Core i7-9700K is faster than the Core i5-11400. Despite this, the Core i5-11400 has the advantage in our gaming benchmark.

In terms of the number of cores of each of these CPUs, the Core i7-9700K has slightly more cores than the Core i5-11400. Indeed, the Core i7-9700K has 8 cores compared to 6 cores found in the Core i5-11400. Despite this, the Core i5-11400 has more threads than the Core i7-9700K. Both the Core i5-11400 and Core i7-9700K have the same clock speed. Despite this, the Core i7-9700K has a slightly higher turbo speed. A Core i5-11400 CPU outputs less heat than a Core i7-9700K 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 i5-11400 has significantly more L2 cache when compared to the Core i7-9700K. However, both these chips have the same amount of L3 cache.

The more cores a CPU has, the better the overall performance will be in parallel workloads such as multitasking. Many CPUs have more threads than cores, this means that each physical core is split into multiple logical cores, making them more efficient. Indeed, the Core i5-11400 has more threads than cores. Each physical core is split into multiple threads.
