Intel Core i5-10400

Intel Core i5-10400: Comprehensive Review of the Budget Processor of 2025
April 2025
1. Key Specifications: Architecture, Performance, and Key Features
Codename and Manufacturing Process
The Intel Core i5-10400 processor, released in 2020, is based on the Comet Lake architecture and manufactured using a 14nm process. Although by 2025 this process is considered outdated (new chips are using 7-10nm), the i5-10400 remains relevant due to its low price and balanced performance.
Cores, Threads, and Cache
- 6 cores and 12 threads thanks to Hyper-Threading.
- Base frequency: 2.9 GHz, max turbo frequency: 4.3 GHz.
- L3 cache: 12 MB — sufficient for handling moderate workloads.
Power Consumption and Graphics
- TDP 65W: low power consumption, suitable for compact builds.
- Integrated Intel UHD Graphics 630: handles office tasks, 4K video playback, and less demanding games (e.g., CS:GO on low settings).
Performance
- Geekbench 6: 1422 (Single-Core), 5460 (Multi-Core).
- In tests from 2025, the processor demonstrates:
- Smooth browsing with 20+ tabs open.
- Video rendering in 1080p (Premiere Pro) in an acceptable time (15-20 minutes for a 10-minute clip).
- Gaming on medium settings with a discrete graphics card (e.g., GTX 1660 Super).
Key Features
- Support for Intel Optane Memory to accelerate HDD performance.
- Turbo Boost 2.0 and Hyper-Threading technologies.
2. Compatible Motherboards: Sockets and Chipsets
LGA 1200 Socket
The processor requires motherboards with the LGA 1200 socket. Popular chipsets include:
- H410 / B460: budget options without overclocking (prices in 2025: $70-100).
- H470 / Z490: support for PCIe 3.0, more lanes for peripherals (Z490 allows overclocking for CPUs with the “K” index).
Selection Recommendations
- For office PCs: H410 (e.g., ASRock H410M-HDV).
- For home systems: B460 (MSI B460M-A Pro) — a balance of price and functionality.
- For upgrades: Z490 (Gigabyte Z490 UD) — a future-proof option if planning to install a more powerful CPU (e.g., i9-10900K).
Features
- On H410/B460 chipsets, memory frequency is limited to 2666 MHz.
- No support for PCIe 4.0 — this is critical only for high-end graphics cards (e.g., RTX 4080+).
3. Supported Memory Types
- DDR4-2666 MHz (on H410/B460) or DDR4-2933 MHz (on Z490).
- Maximum Capacity: 128 GB.
Recommendations
- Basic option: 16 GB (2x8 GB) DDR4-2666 — sufficient for gaming and multitasking.
- For work tasks: 32 GB DDR4-2666 (rendering, virtualization).
Limitations
- DDR5 not supported — keep this in mind when building a “future-proof” PC.
4. Power Supplies: Power Calculation
- Processor TDP: 65W.
- Recommended PSU wattages:
- Without a discrete graphics card: 300-400W.
- With a graphics card at the level of RTX 3060: 500-600W.
- For RTX 4070 and above: 650+W.
PSU Examples
- For budget builds: EVGA 500 BR (500W, 80+ Bronze, $50).
- For gaming PCs: Corsair CX650M (650W, 80+ Bronze, $80).
Tip: Don’t skimp on the PSU — low-quality models may cause system instability.
5. Pros and Cons of the Processor
Pros:
- Low price ($120-150 in 2025).
- Energy efficiency (suitable for compact cases).
- Good multi-threaded performance.
Cons:
- Outdated 14nm process.
- No support for PCIe 4.0 and DDR5.
- Overclocking limitations (only for “K” series models).
6. Use Cases
- Office Tasks: Working with documents, video conferencing, multitasking.
- Multimedia: 4K video streaming, editing home videos.
- Gaming: Comfortable performance with GTX 1660 Super or RX 6600 (60 FPS in Full HD in Cyberpunk 2077 on medium settings).
- Work Tasks: Programming, 3D modeling (Blender), rendering in resolutions up to 1080p.
Limitations: Not suitable for 4K gaming, professional 8K video editing, or neural network tasks.
7. Comparison with Competitors
AMD Ryzen 5 3600 ($130-150):
- Pros: 7nm process, larger cache (32MB), PCIe 4.0 support.
- Cons: Higher TDP (65W vs 95W), weaker in single-threaded tasks.
AMD Ryzen 5 5600G ($140-160):
- Pros: Integrated Vega 7 graphics (stronger than UHD 630), PCIe 4.0.
- Cons: Lower frequency in multi-threaded scenarios.
Conclusion: The i5-10400 excels in the budget segment if PCIe 4.0 is not required.
8. Practical Assembly Tips
- Cooling: The boxed cooler is sufficiently effective, but for quieter operation, consider the DeepCool GAMMAXX 400 ($25).
- Storage: Always use an SSD (e.g., Kingston A2000 500GB, $45) for the OS.
- Upgrade: The maximum CPU for LGA 1200 is the i9-10900K (10 cores).
- BIOS: Update the motherboard firmware for compatibility.
9. Final Thoughts: Who is the i5-10400 for?
This processor is an ideal choice for:
- Budget Builds: If the goal is to save money without sacrificing performance.
- Office and Home PCs: For work, study, and multimedia.
- Beginner Gamers: In conjunction with a graphics card like the RTX 3060.
Why in 2025? Despite its age, the i5-10400 remains a cost-effective option thanks to its low price and sufficient power for everyday tasks. However, for resource-intensive projects (AI, 4K rendering), it is better to choose more modern models.
