Intel Core i5-6585R: Overview and Relevance in 2025

Comprehensive guide to the processor with integrated Iris Pro 580 graphics

1. Key Specifications: Skylake Architecture and Main Features

The Intel Core i5-6585R, released in 2016, is based on the Skylake microarchitecture (6th generation) and a 14nm process. Despite its age, it maintains niche popularity due to a unique combination of characteristics:

- Cores and Threads: 4 cores, 4 threads (no Hyper-Threading). Base frequency is 2.8 GHz, with a maximum turbo frequency of 3.6 GHz.

- Integrated Graphics: Iris Pro Graphics 580 with 72 Execution Units (EUs) and 128 MB of eDRAM. This solution outperforms standard HD graphics, offering support for 4K@60 Hz and DirectX 12.

- Cache: 6 MB SmartCache.

- TDP: 65 W.

Key Features:

- eDRAM (embedded memory) accelerates graphics rendering and data processing.

- Support for Clear Video HD technology to enhance streaming video quality.

- Optimization for energy-efficient systems.

2. Compatible Motherboards: Sockets and Chipsets

The processor uses the LGA 1151 socket (v1 version, not compatible with Coffee Lake boards). Suitable chipsets include:

- H110, B150, H170, Q170, Z170 — basic options for office PCs (e.g., ASUS H170-PRO).

- Z170 — for enthusiasts, supports memory overclocking (but not CPU multiplier).

Selection Considerations:

- Ensure that the motherboard BIOS is updated to a version that supports Skylake.

- Using eDRAM requires a 100/200 series chipset.

- Avoid boards with limited VRM power delivery; the processor is sensitive to voltage stability.

3. Supported Memory: DDR4 and Limitations

The i5-6585R works with DDR4-2133 MHz in dual-channel mode. Maximum capacity is 64 GB (depends on the motherboard).

Recommendations:

- Optimal configuration: 2 modules of 8 GB (e.g., Kingston HyperX Fury DDR4-2133).

- Higher memory speeds (e.g., 2400 MHz) will operate at reduced rates.

4. Power Supply: Power Calculation

With a TDP of 65 W and no discrete GPU, a power supply of 400–500 W is sufficient (e.g., be quiet! System Power 10 450W).

Scenarios:

- System with GPU (NVIDIA GTX 1650): choose a PSU of 500–600 W (Corsair CX550M).

- For compact builds, low-power solutions like FSP FlexGURU 500W are suitable.

5. Pros and Cons: Why is it Still Relevant in 2025?

Pros:

- Powerful integrated graphics for its time — handles light gaming (Dota 2, CS:GO on medium settings).

- Energy efficiency: suitable for mini-PCs and HTPCs.

- Support for 4K video and hardware HEVC decoding.

Cons:

- 4 threads are insufficient for multitasking in 2025 (e.g., streaming + gaming).

- No support for PCIe 4.0, USB 3.2 Gen 2x2.

- Limited upgrade potential: the platform has become outdated.

6. Use Cases: Who is This Processor For?

- Office Tasks: Working with documents, browsers, video conferencing.

- Multimedia: Viewing 4K content, creating simple videos (Adobe Premiere Pro with optimizations).

- Light Gaming: Overwatch 2 on low settings (1080p, ~40 FPS), indie projects.

- Home Servers: NAS or media center based on Plex.

Real User Experience: Users report smooth performance when paired with an SSD (Samsung 870 EVO) and 16 GB of RAM.

7. Comparison with Competitors: What to Choose Instead?

- AMD Ryzen 3 5300G (2023): 4 cores/8 threads, Vega 6. Price: ~$120. Pros — supports DDR4-3200, more recent architecture.

- Intel Core i3-12100 (2022): 4 cores/8 threads, UHD Graphics 730. Price: ~$110. Cons — weaker graphics.

Conclusion: The i5-6585R wins in scenarios where integrated graphics are critical without upgrading to discrete solutions.

8. Practical Assembly Tips

- Motherboard: Look for models with HDMI 2.0 for 4K output (e.g., Gigabyte GA-B150M-D3H).

- Cooling: The stock cooler is sufficient, but for quieter operation, DeepCool GAMMAXX 400 is suitable.

- Storage: An SSD (Crucial MX500 500 GB) is essential to eliminate performance bottlenecks.

- Case: For HTPC — compact Mini-ITX (Fractal Design Node 304).

9. Final Conclusion: Who Should Consider the i5-6585R in 2025?

This processor is worth considering if:

- You need a budget PC for an office or media center without a discrete graphics card.

- Access to used components is available (new boards and CPUs are rare, prices for leftovers are $150–200).

- An energy-efficient system with 4K support is required.

Alternative: For those willing to spend $200–250, it’s better to choose newer AMD APUs (Ryzen 5 8600G) or Intel Core i5-13400 with a more current platform.

The Intel Core i5-6585R remains a specialized solution, but in the age of DDR5 and 5nm processes, its niche is gradually diminishing. However, for less demanding users, it can still serve as the foundation for a stable and quiet system.
