Core i5-8400 vs Core i5-1345U benchmarks

According to the hardwareDB Benchmark tool, the Core i5-1345U is faster than the Core i5-8400. Despite this, the Core i5-8400 has the advantage in our gaming benchmark.

With info from our database, we find that the Core i5-1345U has significantly more cores with 10 cores whereas the Core i5-8400 has 6 cores. It also has more threads than the Core i5-8400. With our hardware info, we find that the Core i5-8400 has a significantly higher clock speed than the Core i5-1345U. Despite this, the Core i5-1345U has a slightly higher turbo speed. The cache sizes of these CPUs are different. Indeed, the Core i5-1345U has significantly more L2 cache than the Core i5-8400. The Core i5-1345U also has slightly 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. For instance, the Core i5-8400 has the same number of threads as cores. This means the the CPU does not support hyperthreading.
