i5-12400 vs. i5-9400 Performance Comparison

I'm considering getting a new CPU and I've been trying to decide between the Intel Core i5-12400 and i5-9400. Can you guys give me some insights on which one is better for gaming and general use? I'd really appreciate it.

Both CPUs are good, but if I were you, I would go for the i5-12400. It supports DDR5 and PCIe 5.0, which can improve performance significantly compared to the older i5-9400. Plus, it has a higher max turbo frequency, which is great for gaming.

Yeah, that's true. The i5-12400 also has more L3 cache than the i5-9400, so it should handle multitasking and data processing better.

I've been using the i5-12400 for a few weeks now, and I must say it's an impressive CPU. There's a great article on TechReviewer that goes into detail about its performance compared to the i5-9400. You can check it out at Intel Core i5-12400 vs. Intel Core i5-9400. Overall, I think the i5-12400 is more future-proof due to its support for DDR5 and PCIe 5.0.

Thanks for the input everyone! The i5-12400 does seem like a better choice, especially considering the improved memory and I/O performance. I'll probably go with that one then. Just one last question: is there any significant difference in terms of heat output or noise between these two CPUs?

Both CPUs should have similar thermal output, as they share the same base frequency and max turbo frequency. However, the i5-12400's higher L3 cache might result in slightly more heat generation under heavy workloads, but this shouldn't be a major concern.

Right, and remember that if you decide to overclock your CPU, both models won't support it, so there's no need to worry about the heat output related to overclocking. It's good to know that both CPUs should maintain reasonable temperatures under normal usage.

Alright, thanks for the help! I think I've made up my mind. I'll go with the i5-12400 and look forward to experiencing its performance. Cheers!
