Intel Core i3-10100T vs Intel Core i5-9400T

Core i3-10100T vs Core i5-9400T benchmarks

Our benchmark analysis concludes that the Core i5-9400T performs better than the Core i3-10100T. Despite this, the Core i3-10100T 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 i3-10100T that has 4 cores. Despite this, the Core i3-10100T has more threads than the Core i5-9400T. With our hardware info, we find that the Core i3-10100T has a significantly higher clock speed than the Core i5-9400T. Also, the Core i3-10100T has a slightly higher turbo speed. Both these chips have an identical TDP (Thermal Design Power). 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 i3-10100T has more threads than cores. Each physical core is split into multiple threads.
