Core i5-8350U vs Core i5-8400 specs and performance
According to the hardwareDB Benchmark tool, the Core i5-8400 is faster than the Core i5-8350U. Furthermore, our gaming benchmark shows that it also outperforms the Core i5-8350U in all gaming tests too.
When comparing core counts for these CPUs, we notice that the Core i5-8400 has significantly more cores with 6 cores compared to the Core i5-8350U that has 4 cores. Despite this, the Core i5-8350U has more threads than the Core i5-8400. These CPUs have different clock speeds. Indeed, the Core i5-8400 has a significantly higher clock speed compared to the Core i5-8350U. Also, the Core i5-8400 has a slightly higher turbo speed. A Core i5-8350U CPU outputs less heat than a Core i5-8400 CPU because of its significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. In terms of cache, the Core i5-8400 has significantly more L2 cache when compared to the Core i5-8350U. The Core i5-8400 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 i5-8350U has more threads than cores. Each physical core is split into multiple threads.
