On our gaming index the Core i5-7400 scores 24 and the Ryzen 5 2400 scores 23.1, about 4% faster for gaming. That gap is small and mostly shows up at 1080p with a very fast graphics card.
The Core i5-7400 has 4 cores and 4 threads, and the Ryzen 5 2400 has 4 cores and 8 threads. Core counts are the same, so cache size and clock speed decide the difference. Boost clocks are 3.5 GHz and 3.4 GHz.
The Core i5-7400 uses the LGA1151 socket and the Ryzen 5 2400 uses AM4, so they need different motherboards, and often different memory. When you compare prices, count the board as well as the chip.
Rated power is 65 W for the first and 65 W for the second. That is close enough that cooling needs will be similar.
We do not have launch prices for both chips, so we cannot compare value.
At 1080p the Core i5-7400 can feed a card up to the GeForce RTX 4050 Laptop before it holds the card back by more than 10 percent. The Ryzen 5 2400 reaches the Arc A580. Both chips are in the same range for graphics card pairing.
Choose the Core i5-7400 if you want the faster gaming chip and the same or more cores. Choose the Ryzen 5 2400 if you would rather spend the difference on a graphics card, which does more for frame rates in most games.
The Core i5-7400 is about 4% faster than the Ryzen 5 2400 in our estimate.
If your graphics card is already the limit in your games, a faster processor adds little. Use the bottleneck calculator to check your own pairing.
