Intel i5-10400 vs. i5-9400F Performance

I'm looking for some advice on which CPU to get, the Intel Core i5-10400 or the i5-9400F. Can anyone help me out?

The i5-10400 and the i5-9400F are quite similar in terms of core counts, frequencies, and cache capacities. However, the i5-10400 offers a better single-core turbo frequency at 4.30 GHz compared to the i5-9400F's 4.10 GHz. The i5-1040 also has a larger L3 cache with 12 MB instead of the 9 MB found in the i5-9400F.

What about their overclocking capabilities? Are they both capable of being overclocked?

Unfortunately, both the i5-10400 and the i5-9400F lack overclocking support. So, you won't be able to push their performance beyond their default limits.

I'm also considering these two processors for my new build. How about their DDR4 support? Are there any significant differences?

The i5-10400 and the i5-9400F have mediocre DDR4 support with a max stock speed of 2666 MHz, which might not be optimal for high-end gaming or content creation.

I've read that PCIe version is an important factor in determining performance. How do these two CPUs compare in this regard?

The i5-10400 and the i5-9400F both support PCIe 3.0, which may limit their potential for the latest SSDs and graphics cards. For optimal compatibility with high-end components, you might want to consider a CPU that supports PCIe 4.0.

That's interesting. So if I were to choose between these two, which one would you recommend?

I would recommend the i5-10400 due to its better single-core turbo frequency and larger L3 cache. However, it's important to consider your specific use case and budget when making a decision.

Thanks for the help! I'll definitely keep these factors in mind as I make my final choice. By the way, I found this TechReviewer article Intel Core i5-10400 vs. Intel Core i5-9400F that compares these two CPUs in detail. It provides some great insights into their performance differences.
