Ryzen 5 3450U vs Core i5-7400 comparison

In our benchmarks, the Core i5-7400 beats the Ryzen 5 3450U in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Ryzen 5 3450U in all gaming tests too.

Our spec comparison shows that they have an identical amount of cores but the Ryzen 5 3450U has more threads. With our hardware info, we find that the Core i5-7400 has a much higher clock speed than the Ryzen 5 3450U. A Ryzen 5 3450U 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. The info from our database shows that the Ryzen 5 3450U has more L2 cache than the Core i5-7400. Despite this, the Core i5-7400 has significantly more L3 cache compared to the Ryzen 5 3450U.

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 Ryzen 5 3450U has more threads than cores. Each physical core is split into multiple threads.
