Intel Core i5-4670K: Review and Relevance in 2025
Despite the Intel Core i5-4670K processor being released over ten years ago, it still piques the interest of budget build enthusiasts. In this article, we will explore how relevant this CPU is today, what tasks it can handle, and who might find it useful.
Key Specifications: Architecture, Manufacturing Process, and Key Features
Codename and Architecture
The processor is based on the Haswell microarchitecture (4th generation Intel Core), which succeeded Ivy Bridge. The main improvements include energy efficiency optimization and a 5-10% increase in IPC (Instructions Per Cycle) performance compared to its predecessors.
Manufacturing Process and Thermal Output
The i5-4670K is manufactured using a 22nm process. Its TDP (thermal design power) is 84W, which is considered moderate for 2025. However, when overclocked, power consumption can reach 100-110W.
Performance
- Frequencies: Base clock — 3.4 GHz, turbo boost — up to 3.8 GHz.
- Cores and Threads: 4 cores, 4 threads (Hyper-Threading is absent).
- Cache: 6 MB L3.
- Graphics: Intel HD 4600 (supports DirectX 11.1, 4K through DisplayPort).
In the Geekbench 6 test, the CPU achieves 1275 points in single-core mode and 3600 points in multi-core mode. In comparison, the modern budget Intel Core i3-13100 (13th generation) scores around 2200/8000 points.
Key Features
- Unlocked Multiplier: The ability to overclock is the main advantage of the "K-series."
- PCIe 3.0: Supports 16 lanes of PCIe, sufficient for a single powerful graphics card.
- Integrated Graphics: The HD 4600 can handle office tasks and older games (for example, CS:GO at low settings offers 40-50 FPS).
Compatible Motherboards: Sockets and Chipsets
LGA 1150 Socket
The processor uses the LGA 1150 socket, which is supported only by motherboards with Intel 8th and 9th generation chipsets (Z87, H87, B85, H81, Z97).
Recommended Chipsets
- Z87/Z97: For overclocking (e.g., ASUS Z97-A or MSI Z87-GD65).
- H87/B85: For basic builds without overclocking.
- H81: Budget option, but limited in PCIe slots and SATA ports.
Selection Features
- LGA 1150 motherboards are no longer being produced, so they must be sought on the secondary market.
- Check the condition of VRM modules on the boards — older models may have degraded due to long-term use.
Supported Memory: DDR3 Limitations
The i5-4670K works only with DDR3 (officially up to 1600 MHz). In practice, many boards allow memory overclocking up to 1866-2133 MHz, but the performance gain in games is minimal (5-8%).
Recommendations
- Use dual-channel kits (2×8 GB) to maximize bandwidth.
- Avoid memory with a voltage higher than 1.5V — this may damage the controller.
Power Supply: Power Calculation
Basic Requirements
- Without overclocking: A power supply of 400-450W with an 80+ Bronze rating.
- With overclocking and a discrete graphics card (e.g., NVIDIA GTX 1660): 500-600W.
Configuration Examples
- Office PC (without a GPU): Corsair CV450 (450W, $50).
- Gaming PC (with GPU): be quiet! System Power 10 (600W, $70).
Pros and Cons of the Processor
Advantages
- Low Price: On the secondary market, the CPU costs $30-50.
- Overclocking Potential: Frequencies can be increased to 4.2-4.5 GHz (with good cooling).
- Energy Efficiency: For its age, a TDP of 84W is a respectable figure.
Disadvantages
- Outdated Platform: Lacks support for DDR4, PCIe 4.0, USB 3.2 Gen 2.
- Absence of Hyper-Threading: Multi-threaded performance is weaker than modern Core i3s.
- Risk of Used Purchase: Most units have been actively used for 8-10 years.
Use Cases: Where is the i5-4670K Relevant in 2025
1. Office Tasks and Web Browsing: With an SSD and 16 GB RAM, the system remains responsive.
2. Media Center: The integrated graphics support 4K via DisplayPort.
3. Retro Gaming: Games up to 2015 (Skyrim, GTA V on medium settings).
4. Servers: For NAS or home servers based on Linux.
Practical Example:
A user built a PC with the i5-4670K, GTX 970, and 16 GB DDR3. In games like The Witcher 3, he achieves 45-50 FPS on medium settings (1080p).
Comparison with Competitors
1. AMD FX-8350 (2012):
- 8 cores but weaker in single-threaded tasks (Geekbench 6: ~900/3200).
- Heats up more (TDP 125W).
2. Intel Core i3-10100 (2020):
- 4 cores/8 threads, DDR4 support.
- Geekbench 6: ~1500/4500.
- New models cost $120-150.
3. Ryzen 3 3300X (2020):
- 4 cores/8 threads, PCIe 4.0.
- Geekbench 6: ~1600/4800.
Conclusion: The i5-4670K lags behind modern budget CPUs but wins in price on the secondary market.
Practical Assembly Tips
1. Cooling: For overclocking, use coolers like the DeepCool Gammaxx 400 ($25).
2. SSD is a Must: Samsung 870 EVO (500 GB, $60) will eliminate SATA III bottlenecks.
3. Add a Graphics Card: Even a used GTX 1060 ($80) can turn the system into a gaming machine.
4. Check BIOS: Update motherboard firmware for SSD and peripheral compatibility.
Final Conclusion: Who Should Consider the i5-4670K?
This processor is worth considering for:
- Budget Users: Building a PC for $200-300 (including used components).
- Retro Computer Enthusiasts: For games and software from the 2010s.
- Owners of Old Systems: As a temporary solution before a complete upgrade.
Why Not? If you need support for modern games, VR, or heavy work applications, it's better to choose even a budget Ryzen 5 5500 or Core i3-13100.
In 2025, the Intel Core i5-4670K remains a niche solution, but its potential is not yet exhausted. It is the choice for those who value a balance between price and performance within a limited budget.
