Intel Core i5-10400 vs Intel Core i7-7700

Core i5-10400 vs Core i7-7700 benchmarks

In our benchmarks, the Core i5-10400 beats the Core i7-7700 in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-7700 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 i7-7700 that has 4 cores. It also has more threads than the Core i7-7700. These CPUs have different clock speeds. Indeed, the Core i7-7700 has a slightly higher clock speed compared to the Core i5-10400. Despite this, the Core i5-10400 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. In terms of cache, the Core i5-10400 has significantly more L2 cache when compared to the Core i7-7700. The Core i5-10400 also has significantly 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. Indeed, the Core i5-10400 has more threads than cores. Each physical core is split into multiple threads.
