Intel Core i7-8700K in 2025: Is it worth considering an outdated processor?

April 2025


1. Key Features: Architecture and Performance

Codename and Technology Process

The Intel Core i7-8700K, released in 2017, belongs to the Coffee Lake generation. It is one of Intel's first 6-core processors aimed at the consumer market. The technology process is 14 nm, which is considered outdated by 2025 (modern chips use 5-7 nm). However, at the time of its release, it was a breakthrough: 6 cores and 12 threads with a base frequency of 3.7 GHz and Turbo Boost up to 4.7 GHz.

Key Features

- Hyper-Threading: 12 threads for multitasking.

- Unlocked Multiplier: Overclocking capability (though not all motherboards support it).

- Integrated Graphics: Intel UHD Graphics 630 — suitable for office tasks or emergencies, but not for gaming.

- L3 Cache: 12 MB — sufficient for reducing latency in games and applications.

Performance

According to Geekbench 6 (2025):

- Single-Core: 1576 points — a modest result for 2025 (modern processors score 2000+).

- Multi-Core: 6433 points — acceptable for basic work tasks but lags behind even budget Ryzen 5 7500F (around 8000 points).

Practical Example: In 2023, a user on Reddit built a PC with an i7-8700K and RTX 3060 for gaming at Full HD. In 2025, such a system still runs Cyberpunk 2077 at medium settings (45-60 FPS), but experiences drops in CPU-intensive scenes.


2. Compatible Motherboards: What to Choose in 2025?

Socket and Chipsets

The processor uses LGA 1151 v2. Compatible chipsets include:

- Z370: For overclocking (e.g., ASUS ROG Strix Z370-E).

- H370/B360/H310: Budget boards without overclocking.

Selection Tips

- New Boards: No longer produced. In 2025, only used options remain (price: $50-100) or leftover new ones (up to $150).

- Limitations: No support for PCIe 4.0/5.0, USB 3.2 Gen 2x2, Thunderbolt 4.

- Advice: Look for boards with reliable VRM (e.g., MSI Z370-A Pro) — they handle overclocking better.


3. Supported Memory Types

DDR4-2666: Maximum speed without overclocking. Compatible with modules up to 64 GB (depends on the motherboard).

No DDR5: In 2025, this is a critical downside — new games and applications are optimized for high-speed memory.

Recommendations:

- Use 2 DDR4-3200 modules (in XMP mode) for a small performance boost.

- Example: 16 GB Kingston Fury DDR4-3200 (around $60 for a set).


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

Processor TDP: 95 W, but with overclocking, consumption can reach 140-150 W.

Recommendations:

- Without a discrete graphics card: A 400 W PSU (e.g., be quiet! Pure Power 11 400W, $55).

- With a graphics card like the RTX 4060: A 550-650 W PSU (Corsair RM650x, $90).

- Important: Choose units with an 80+ Bronze certification or higher.


5. Pros and Cons of the i7-8700K in 2025

Pros:

- Affordable price: New processors (if available) are $150-200 compared to $250-300 for the Ryzen 5 7600.

- Good multi-core performance for older applications.

- Overclocking potential (up to 5.0 GHz with good cooling).

Cons:

- Outdated technology process: High power consumption and heat output.

- No support for modern standards (PCIe 4.0, DDR5).

- Challenges with upgrades: New GPUs and SSDs may not operate at full speed.


6. Use Cases

Gaming:

- Full HD/Medium Settings: CS2, Fortnite, GTA V — 60+ FPS.

- Modern AAA Titles: FPS drops may occur due to CPU limitations (e.g., Starfield).

Work Tasks:

- Video Editing: In Premiere Pro, rendering 1080p videos will take 20-30% longer than on the Ryzen 5 7600.

- 3D Modeling: Suitable for basic use in Blender.

Multimedia:

- Streaming via Plex.

- Office applications and web browsing.


7. Comparison with Competitors

AMD Ryzen 5 3600 (2019):

- Cheaper ($100-120 used), but worse in single-core performance (Geekbench 6: ~1400).

- Supports PCIe 4.0 (with a BIOS update).

Intel Core i5-12400F (2022):

- Newer, higher IPC, supports DDR4/DDR5.

- Price for new units: $180-200.

Conclusion: The i7-8700K falls behind modern budget CPUs but outperforms older models thanks to its 12 threads.


8. Assembly Tips

- Cooling: A cooler like the DeepCool AK400 ($35) or the Arctic Liquid Freezer II 240 (for overclocking).

- Motherboard: Look for models with USB 3.1 and M.2 NVMe (e.g., Gigabyte Z370 Aorus Gaming 5).

- Upgrade: If you already have an LGA 1151 v2 board, the i7-8700K is a good replacement for an i3/i5. For new builds, consider the AM5 or LGA 1700 platforms.


9. Final Conclusion: Who is the i7-8700K Suitable For?

This processor is worth considering:

1. For upgrading older systems: If you already have a compatible motherboard.

2. Budget builds: When you need to save money while getting 6 cores.

3. Enthusiasts: For experimentation with overclocking on the second-hand market.

Alternative: If the budget allows, it's better to get the Ryzen 5 7600 or Intel Core i5-13400F — they offer DDR5 and PCIe 5.0 support for a small premium.

In 2025, the i7-8700K is a "workhorse" for niche tasks but not a foundation for a future-oriented system.
