Intel Core i3-7350K vs Intel Core i5-6400

Core i3-7350K vs Core i5-6400 comparison

In our benchmarks, the Core i5-6400 beats the Core i3-7350K in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Core i3-7350K in all gaming tests too.

When comparing core counts for these CPUs, we notice that the Core i5-6400 has significantly more cores with 4 cores compared to the Core i3-7350K that has 2 cores. But they both have the same number of threads. With our hardware info, we find that the Core i3-7350K has a significantly higher clock speed than the Core i5-6400. A Core i3-7350K CPU outputs less heat than a Core i5-6400 CPU because of its slightly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. The cache sizes of these CPUs are different. Indeed, the Core i5-6400 has significantly more L2 cache than the Core i3-7350K. The Core i5-6400 also has significantly more 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 i3-7350K has more threads than cores. Each physical core is split into multiple threads.
