Intel Core i7-5775C Broadwell: Comprehensive Review for 2025

(Relevant as of April 2025)

1. Key Specifications: Architecture, Process Technology, and Key Features

The Intel Core i7-5775C processor, released in 2015, still attracts interest due to its unique technologies for its time.

Broadwell Architecture and 14nm Process Technology

The chip is built on the Broadwell microarchitecture (5th generation Core) with a 14nm process technology. This has allowed for reduced power consumption (TDP of 65W) while maintaining high performance. Unlike its predecessors (Haswell), Broadwell brought improvements in IPC (Instructions Per Cycle) of 5-10%, which is particularly noticeable in single-threaded tasks.

4 Cores, 8 Threads, and Cache

The processor features 4 cores with Hyper-Threading (8 threads) and 6MB of L3 cache. In the Geekbench 6 test (2025), it shows:

- 1410 points in single-threaded mode;

- 4832 points in multi-threaded mode.

For comparison, the modern Ryzen 5 5500 (6 cores/12 threads) scores around ~1600/6000 points but costs about $180.

Key Features

- Iris Pro Graphics 6200 — integrated graphics with eDRAM (128MB). It surpasses the basic Intel UHD solutions and handles gaming at 720p (e.g., CS:2 on low settings).

- Support for PCIe 3.0 — relevant for NVMe SSDs through adapters.

- Energy Efficiency — ideal for compact systems.

2. Compatible Motherboards: Sockets and Chipsets

LGA1150: Limited Choices in 2025

The processor uses the LGA1150 socket. Suitable chipsets include:

- H97/Z97 — for overclocking (only Z97 supports it);

- H81/B85 — budget options without support for PCIe 3.0.

Example Models:

- ASUS Z97-A (price on remaining stock: $120–150) — overclocking capability, 4 DDR3 slots;

- Gigabyte H97-D3H ($80–100) — basic stability.

Selection Tips:

- Check for BIOS updates for compatibility.

- Look for motherboards with M.2 slots (require adapters for NVMe).

3. Supported Memory: DDR3L and Hidden Limitations

The processor works with DDR3L-1600 MHz (officially) or DDR3 (unofficially, limited to 1.5V voltage).

- Maximum Capacity: 32GB (4×8GB);

- Recommendations: Optimal is 16GB (2×8GB) for gaming and multitasking.

Important: No support for DDR4/DDR5. If modern memory is needed, this processor is not suitable.

4. Power Supply: Power Recommendations

With a TDP of 65W, even with a discrete graphics card (e.g., GTX 1660), a 500W PSU will suffice:

- Budget: EVGA 500 W1 ($45) — for basic builds;

- Premium: Corsair CX550M ($80) — modular design, 80 Plus Bronze certification.

Tip: For systems with high-end GPUs (RTX 3060 and above), choose a PSU of at least 600W.

5. Pros and Cons of i7-5775C in 2025

Pros:

- Energy Efficiency — suitable for HTPCs or mini-PCs.

- Iris Pro Graphics — no need for a discrete graphics card for office tasks and casual gaming.

- Multithreading — 8 threads for rendering in Blender or video encoding.

Cons:

- Outdated Platform — no support for DDR4, PCIe 4.0, USB 3.2 Gen 2.

- Limited Upgrade Path — maximum for LGA1150: Xeon E3-1285 v4 or i7-4790K.

- Price for new units — $150–200 due to rarity.

6. Use Cases: Gaming, Work, and Multimedia

Gaming

- CS:2, Dota 2, GTA V — 60 FPS at medium settings with Iris Pro 6200;

- With discrete GPU (RTX 3050) — 1080p/Ultra in AAA titles from 2023–2024.

Work Tasks

- Photo Editors (Photoshop): Fast processing of RAW files.

- Video Editing (Premiere Pro): Rendering 1080p videos in a reasonable time.

Multimedia

- 4K streaming via HDMI 1.4;

- Quiet operation due to low TDP.

7. Comparison with Competitors

Intel Core i7-6700K (Skylake)

- Pros: DDR4 support, higher IPC, easier to find in 2025.

- Cons: More expensive ($180–220), no eDRAM.

AMD Ryzen 5 1600 (2017)

- Pros: 6 cores/12 threads, AM4 platform with upgrade potential to Ryzen 5000.

- Cons: Requires discrete GPU.

Conclusion: The i7-5775C excels in energy efficiency and integrated graphics but falls short in multithreading.

8. Building Tips

- For upgrading an old PC: If you have an LGA1150 motherboard — it’s a good choice.

- New Build: Opt for B85/H97 with an M.2 adapter for NVMe SSDs (e.g., Samsung 970 EVO).

- Cooling: A box cooler or a budget tower (Deepcool Gammaxx 400) will suffice.

Example Build for $400:

- CPU: i7-5775C ($160);

- Motherboard: ASUS H97-PLUS ($100);

- RAM: 16GB DDR3 ($50);

- SSD: Kingston A2000 500GB ($60);

- PSU: EVGA 500 W1 ($45).

9. Final Thoughts: Who is the i7-5775C Suitable for in 2025?

This processor is relevant for:

1. Budget build enthusiasts — if there’s an existing LGA1150 platform.

2. Compact PC lovers — thanks to low TDP and Iris Pro.

3. Secondary market users — as a temporary solution before transitioning to DDR5/AM5.

Alternative: For new systems, consider Ryzen 5 5500 or Core i3-13100F — they offer better performance and modern technologies.

If you find the i7-5775C for under $150 and want to revive an old PC — it's a great option. However, for future upgrades, plan to transition to current platforms.
