Core i3-10105 vs Core i5-9400T comparison

Our benchmark analysis concludes that the Core i5-9400T performs better than the Core i3-10105. Furthermore, our gaming benchmark shows that it also outperforms the Core i3-10105 in all gaming tests too.

With info from our database, we find that the Core i5-9400T has significantly more cores with 6 cores whereas the Core i3-10105 has 4 cores. Despite this, the Core i3-10105 has more threads than the Core i5-9400T. These CPUs have different clock speeds. Indeed, the Core i3-10105 has a significantly higher clock speed compared to the Core i5-9400T. Also, the Core i3-10105 has a slightly higher turbo speed. The Core i5-9400T outputs less heat than Core i3-10105 thanks to a significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.

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 i3-10105 has more threads than cores. Each physical core is split into multiple threads.
