Intel Core i3-8350K vs Intel Core i5-9400T

Core i3-8350K vs Core i5-9400T comparison

Our benchmark analysis concludes that the Core i5-9400T performs better than the Core i3-8350K. Despite this, the Core i3-8350K has the advantage in our gaming benchmark.

When comparing core counts for these CPUs, we notice that the Core i5-9400T 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. These CPUs have different clock speeds. Indeed, the Core i3-8350K has a significantly higher clock speed compared to the Core i5-9400T. The Core i5-9400T outputs less heat than Core i3-8350K thanks to a significantly 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 i5-9400T has significantly more L2 cache than the Core i3-8350K. The Core i5-9400T also has slightly more L3 cache.

Modern CPUs generally have more logical cores than physical cores, this means that each core is split into multiple virtual cores, improving efficiency for parallel workloads. For instance, the Core i3-8350K has the same number of threads as cores. This means the the CPU does not support hyperthreading.
