Intel Core i5-4690K: Architecture, Compatibility, and Practical Use in 2025
Overview of an outdated but still relevant processor for budget-conscious users
1. Key Features: Haswell Architecture and Its Characteristics
The Intel Core i5-4690K, released in 2014, became one of the iconic solutions for gamers and enthusiasts. Its Haswell architecture (4th generation Core) is based on a 22 nm manufacturing process, which at the time provided a balance between performance and energy efficiency.
- Cores and Threads: 4 cores and 4 threads. Despite the lack of Hyper-Threading, the processor shows stable performance in multi-threaded tasks.
- Clock Speeds: Base frequency is 3.5 GHz, turbo mode goes up to 3.9 GHz. The unlocked multiplier allows overclocking the CPU to 4.5–4.7 GHz (with adequate cooling).
- Cache Memory: 6 MB of L3 cache — sufficient for caching data in games and applications.
- Graphics: Intel HD 4600. It allows running undemanding games (e.g., CS:GO at low settings) and working with 4K video via HDMI.
- Performance: In the Geekbench 6 test (2025) — 1273 points (single-core) and 3508 (multi-core). For comparison, a modern budget Intel Core i3-13100 scores around ~1800/6000 points.
Key Features:
- Unlocked multiplier for overclocking.
- Support for AVX2 instructions, relevant for media processing.
- Power-saving technologies like SpeedStep and Turbo Boost 2.0.
2. Compatible Motherboards: LGA 1150 Socket and Selection Tips
The processor uses the LGA 1150 socket, which limits motherboard choices to models released between 2013 and 2015. The main chipsets include:
- Z97/Z87 — optimal for overclocking (support for SLI/CrossFire, voltage regulation). Examples: ASUS Z97-A, MSI Z87-G45.
- H97/H87 — suitable for basic builds without overclocking.
- B85/H81 — budget motherboards with limited features (no RAID, fewer SATA 6 Gbps ports).
Selection Tips for 2025:
- Buy motherboards on the secondary market (price: $30–70). New models are very rare.
- Check the condition of the VRM modules — crucial for stable overclocking.
- Ensure the BIOS is updated to the latest version for compatibility with NVMe SSDs via adapters.
3. Supported Memory: DDR3 and Its Limitations
The i5-4690K works only with DDR3 (officially up to 1600 MHz, but many motherboards support overclocking up to 1866–2133 MHz).
Recommendations:
- Use dual-channel kits (2×8 GB) to maximize bandwidth.
- Avoid high-latency memory (CL9–CL11 are optimal).
- DDR4/DDR5 are not supported — this is the main limitation for upgrades.
4. Power Supply: Power Calculation
With a TDP of 88 W (and up to 120 W when overclocked), this processor does not require an overly powerful PSU.
Recommendations:
- For a system with a GPU like the NVIDIA GTX 1660 Super (TDP 125 W), a 450–500 W PSU is sufficient (e.g., Corsair CX550).
- Choose models with an 80+ Bronze certification or higher.
- Avoid cheap noname power supplies — unstable voltage can damage components.
5. Pros and Cons of the i5-4690K in 2025
Pros:
- Low cost on the secondary market ($40–60).
- Good overclocking potential.
- Sufficient performance for office tasks and older games.
Cons:
- Lack of support for PCIe 4.0/5.0, DDR4, USB 3.2 Gen 2.
- Outdated platform: upgrades require replacing the CPU, motherboard, and RAM.
- Limited multi-threading (4 threads vs. 8+ in modern CPUs).
6. Use Cases: Where the Processor is Still Relevant
- Gaming: Paired with a GTX 1060 or RX 580 GPU, it can handle GTA V, Fortnite, Rocket League at medium settings (1080p/60 FPS). To play Cyberpunk 2077 or Starfield, you will need to lower graphics quality.
- Office and Multimedia: Handles document work, plays 4K video, and performs light editing in DaVinci Resolve.
- Home Lab Server: Energy efficient with enough power for NAS or media server needs.
7. Comparison with Competitors
- AMD FX-8350 (2012): 8 cores, but weak IPC. In games, the i5-4690K performs 15–20% better.
- Intel Core i3-12100 (2024): 4 cores/8 threads, DDR4, PCIe 5.0. 40% faster in multi-threaded tasks.
- Ryzen 5 5500 (2023): 6 cores/12 threads, priced at $120 (new). Completely outperforms the i5-4690K in all scenarios.
Conclusion: The i5-4690K lags behind modern budget CPUs but offers better pricing on the secondary market.
8. Practical Assembly Tips
- Cooling: The stock cooler is sufficient for stock frequencies. For overclocking — tower coolers (DeepCool Gammaxx 400, ~$25).
- Storage: Use a SATA SSD (e.g., Crucial MX500) to speed up the system. NVMe can be accessed via PCIe adapters.
- Graphics Card: Avoid GPUs stronger than the RTX 3060 — the processor will become a bottleneck.
9. Final Conclusion: Who is the i5-4690K Suitable For?
This processor should be considered in three cases:
1. Upgrading an old PC: If you already have a motherboard on LGA 1150.
2. Budget Build: When you need to build a PC for studying or office work for $150–200.
3. Enthusiast Overclockers: For those experimenting with overclocking on a minimal budget.
Alternatives for New Builds: Intel Core i3-13100 ($120) or AMD Ryzen 5 5500 ($130) — more modern and powerful options.
The i5-4690K is a relic of the past that still finds use in niche scenarios. Its time has passed, but for certain tasks, it remains a cost-effective choice.
