Intel Core i5-10400F in 2025: Is It Worth Getting? A Complete Overview

Is it still relevant for budget builds, or is it an outdated option?

1. Key Specifications: What's Under the Hood?

The Intel Core i5-10400F processor, released in 2020, is still found in budget PCs. Its Comet Lake architecture (14 nm) is an evolution of Skylake, optimized for multithreading.

- Cores and Threads: 6 cores / 12 threads. Sufficient for basic multitasking (office tasks, browsing, streaming).

- Clock Frequencies: Base clock — 2.9 GHz, maximum Turbo Boost — 4.3 GHz.

- Cache: 12 MB L3. The response time in applications is acceptable, but lower than that of modern counterparts.

- TDP: 65 W. Low power consumption for a processor of this class.

- Graphics: Absent (the "F" suffix indicates the need for a discrete graphics card).

Performance:

- Geekbench 6: Single-Core — 1432, Multi-Core — 5750. For comparison, the Ryzen 5 5500 (2022) scores around ~1600/6000.

- Gaming: Paired with an RTX 3060, it delivers 60-90 FPS in games from 2022-2023 (for example, Cyberpunk 2077 on medium settings), but it may become a bottleneck in projects from 2024-2025.

Key Features:

- Supports Hyper-Threading.

- Compatible with cheap motherboards.

2. Compatible Motherboards: What to Choose in 2025?

The LGA 1200 socket limits your choice of new motherboards — there are almost none available. Look for leftovers or used ones:

- Chipsets:

- H410/B460: Budget options ($50-70 in 2025). No RAM overclocking above 2666 MHz.

- Z490: Supports XMP profiles for memory overclocking. Used price — $80-100.

Examples of Boards:

- ASRock B460M Pro4 (new — $60-80, if you can find one).

- MSI Z490-A Pro (used — $90-110).

Tip: Don’t overpay for Z490 — the processor doesn’t support overclocking. It's better to get B460 and save money.

3. Memory: DDR4 and No Compromises

The i5-10400F works only with DDR4:

- Max Frequency: 2666 MHz (on H410/B460 chipsets). On Z490, you can install up to 2933 MHz with XMP.

- Recommendations: 16 GB (2x8 GB) DDR4-2666 is optimal for gaming and multitasking. A new set costs $40-60.

Important: DDR5 is not supported. If you plan to upgrade, this processor is a dead-end.

4. Power Supply: How Many Watts Do You Need?

With a TDP of 65 W and an average graphics card (for example, GTX 1660 Super), 450-550 W will be enough.

- Examples:

- Corsair CV550 (550 W, 80+ Bronze, $55-65).

- be quiet! System Power 10 (450 W, $50).

Note: If you're installing a powerful GPU (like RTX 3060 Ti and above), get a PSU of at least 600 W.

5. Pros and Cons: Who Is It Suitable For?

Pros:

- Low price ($100-120 for new, $70-90 used).

- Energy efficiency.

- Sufficient performance for office work and older games.

Cons:

- No PCIe 4.0 (only PCIe 3.0).

- Outdated 14 nm manufacturing process.

- No support for DDR5 or new sockets.

6. Usage Scenarios: Where Is It Relevant?

- Office PCs: Word, Excel, browsing with a dozen tabs.

- Home Theater: 4K video, streaming Netflix.

- Games from 2020-2022: Fortnite, Apex Legends, Elden Ring (on medium settings).

- Video Editing: In Premiere Pro or DaVinci Resolve, it can handle 1080p videos, but for 4K, it will require patience.

Real Example: A build for $400:

- i5-10400F ($100) + GTX 1650 ($130) + 16 GB DDR4 ($50) + 500 GB SSD ($40) + 450 W PSU ($50).

7. Comparison with Competitors

- AMD Ryzen 5 5500 ($110): Better in single-threaded tasks (Geekbench 6 Single-Core ~1600), supports PCIe 4.0.

- Intel Core i3-12100F ($90): 4 cores / 8 threads, but higher IPC. Lags in multithreading.

- Ryzen 5 3600 (used, $80): Comparable performance, but the AM4 platform offers more upgrade options.

Conclusion: The i5-10400F is only advantageous when purchasing used components.

8. Practical Assembly Tips

- SSD is Essential: Kingston NV2 500 GB ($40) will speed up system boot times.

- Cooling: The stock cooler will suffice, but for quieter operation, get a DeepCool Gammaxx 400 ($20).

- Motherboard: Don’t buy expensive models — the LGA 1200 socket has no future.

9. Summary: Who Should Consider the i5-10400F in 2025?

This processor is worth considering only if:

- You need a super budget PC for office work or study.

- You can access cheap used components.

- No upgrades are planned in the next 2-3 years.

Alternative: For the same $200-300, you can build a system on Ryzen 5 5500 or Intel's 12th generation with future-proofing in mind.

Conclusion: The Intel Core i5-10400F in 2025 is a choice for those looking to save at all costs. But remember, technology doesn't stand still, and even a small extra payment will give you access to more modern platforms.

Instruction Set

The instruction set is a hard program stored inside the CPU that guides and optimizes CPU operations. With these instruction sets, the CPU can run more efficiently. There are many manufacturers that design CPUs, which results in different instruction sets, such as the 8086 instruction set for the Intel camp and the RISC instruction set for the ARM camp. x86, ARM v8, and MIPS are all codes for instruction sets. Instruction sets can be extended; for example, x86 added 64-bit support to create x86-64. Manufacturers developing CPUs that are compatible with a certain instruction set need authorization from the instruction set patent holder. A typical example is Intel authorizing AMD, enabling the latter to develop CPUs compatible with the x86 instruction set.
