Core i5-10400 vs Core i7-6700T comparison

According to the hardwareDB Benchmark tool, the Core i5-10400 is faster than the Core i7-6700T. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-6700T in all gaming tests too.

When comparing core counts for these CPUs, we notice that the Core i5-10400 has significantly more cores with 6 cores compared to the Core i7-6700T that has 4 cores. It also has more threads than the Core i7-6700T. These CPUs have different clock speeds. Indeed, the Core i5-10400 has a slightly higher clock speed compared to the Core i7-6700T. Also, the Core i5-10400 has a slightly higher turbo speed. The Core i7-6700T outputs less heat than Core i5-10400 thanks to a significantly 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 i5-10400 has more L2 cache than the Core i7-6700T. The Core i5-10400 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. Indeed, the Core i5-10400 has more threads than cores. Each physical core is split into multiple threads.
