Core i5-9400T vs Core i7-8700T comparison

Our benchmark analysis concludes that the Core i7-8700T performs better than the Core i5-9400T. Furthermore, our gaming benchmark shows that it also outperforms the Core i5-9400T in all gaming tests too.

When comparing these CPUs we notice that they have the same number of cores but the Core i7-8700T has more threads. With our hardware info, we find that the Core i7-8700T has a slightly higher clock speed than the Core i5-9400T. Also, the Core i7-8700T 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. When comparing cache sizes, these CPUs have an identical amount of L2 cache. The Core i7-8700T also has slightly more L3 cache.

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. For instance, the Core i5-9400T has the same number of threads as cores. This means the the CPU does not support hyperthreading.
