AMD Ryzen 5 3400G vs Intel Core i5-8400

Ryzen 5 3400G vs Core i5-8400 benchmarks

According to the hardwareDB Benchmark tool, the Core i5-8400 is faster than the Ryzen 5 3400G. Furthermore, our gaming benchmark shows that it also outperforms the Ryzen 5 3400G 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 Ryzen 5 3400G that has 4 cores. Despite this, the Ryzen 5 3400G has more threads than the Core i5-8400. Our comparison shows that the Ryzen 5 3400G has a slightly higher clock speed compared to the Core i5-8400. Also, the Ryzen 5 3400G 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. The info from our database shows that the Ryzen 5 3400G has more L2 cache than the Core i5-8400. Despite this, the Core i5-8400 has significantly more L3 cache compared to the Ryzen 5 3400G.

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 Ryzen 5 3400G has more threads than cores. Each physical core is split into multiple threads.
