Core i5-7300U vs Core i5-7400 comparison
Our benchmark analysis concludes that the Core i5-7400 performs better than the Core i5-7300U. Furthermore, our gaming benchmark shows that it also outperforms the Core i5-7300U in all gaming tests too.
In terms of the number of cores of each of these CPUs, the Core i5-7400 has significantly more cores than the Core i5-7300U. Indeed, the Core i5-7400 has 4 cores compared to 2 cores found in the Core i5-7300U. But they both have the same number of threads. Our comparison shows that the Core i5-7400 has a slightly higher clock speed compared to the Core i5-7300U. Furthermore, both these CPUs have identical turbo speeds. A Core i5-7300U CPU outputs less heat than a Core i5-7400 CPU because of its 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 i5-7300U has more threads than cores. Each physical core is split into multiple threads.
