Core i3-8350K vs Core i7-8700K comparison

According to the hardwareDB Benchmark tool, the Core i7-8700K is faster than the Core i3-8350K. Furthermore, our gaming benchmark shows that it also outperforms the Core i3-8350K in all gaming tests too.

When comparing core counts for these CPUs, we notice that the Core i7-8700K has significantly more cores with 6 cores compared to the Core i3-8350K that has 4 cores. It also has more threads than the Core i3-8350K. Our comparison shows that the Core i3-8350K has a slightly higher clock speed compared to the Core i7-8700K. A Core i3-8350K CPU outputs less heat than a Core i7-8700K CPU because of its slightly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. The info from our database shows that the Core i7-8700K has more L2 cache than the Core i3-8350K. The Core i7-8700K 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. For instance, the Core i3-8350K has the same number of threads as cores. This means the the CPU does not support hyperthreading.
