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

April 2025

Despite its age, Intel's 4th generation processors continue to capture the interest of enthusiasts and users seeking budget solutions. One of these "veterans" is the Intel Core i7-5775R, released back in 2015. Let's explore its relevance in 2025, what tasks it can handle, and how to build a system based on it.

1. Key Specifications: Architecture and Key Features

Broadwell Architecture and 14nm Process

The i7-5775R belongs to the Broadwell family—a generation that Intel positioned as a transitional phase between Haswell and Skylake. It is built on a 14nm process, which was groundbreaking in 2015. However, today, in the context of 5nm and 3nm chips, this seems outdated.

Specifications:

- 4 cores / 8 threads (Hyper-Threading);

- Base frequency: 3.3 GHz, maximum in Turbo Boost — 3.8 GHz;

- 6 MB L3 cache;

- TDP 65W;

- Integrated graphics Iris Pro 6200 with eDRAM (128 MB).

Key Features:

- Iris Pro 6200 — one of the most powerful integrated GPUs of its time. It can still handle HD video and light gaming like CS:GO at low settings (30-40 FPS).

- eDRAM — additional graphics memory that speeds up rendering.

- Support for AVX 2.0, AES-NI, Virtualization.

Performance (Geekbench 6):

- Single-Core: 1071;

- Multi-Core: 3513.

For comparison, the modern budget Intel Core i3-13100 (2023) scores around ~2200/8000.

2. Compatible Motherboards: Sockets and Chipsets

LGA1150 Socket: Finding Boards in 2025

The i7-5775R uses the outdated LGA1150. No new motherboards for this socket are being produced, but older models can still be found on the secondary market based on chipsets:

- H97/Z97 — optimal choice (supports PCIe 3.0, SATA 6 Gb/s, M.2 in some models);

- H87/B85 — budget options, but may require a BIOS update.

Examples of Models:

- ASUS Z97-A — a board with good VRM cooling and overclocking potential (relevant for multiplier-based processors);

- Gigabyte GA-H97-D3H — a reliable basic model with RAID support.

Important:

- When purchasing, check the BIOS version — a micro-update is required for Broadwell (for example, ASUS Z97-K needs version 2601+).

- M.2 slots in such boards are often limited to PCIe 2.0 x2 speeds (up to 10 Gb/s), which is slower than modern NVMe.

3. Supported Memory: DDR3L and Its Limitations

The processor only works with DDR3L-1600/1333 MHz (maximum capacity — 32 GB). In 2025, DDR3 is an outdated standard, but modules are still available:

- New 16 GB kits (2x8 GB) cost around $40–50 (for example, Kingston HyperX Fury);

- Low power consumption (1.35 V) simplifies compatibility with compact systems.

Tip: Use dual-channel mode to improve the performance of integrated graphics (up to 15-20% increase in games).

4. Power Supply Recommendations

With a TDP of 65W and no overclocking appetite, a system based on the i7-5775R does not require a powerful PSU:

- Without a discrete graphics card: a 300–400W PSU is sufficient (e.g., be quiet! Pure Power 11 400W, ~$55);

- With a graphics card like NVIDIA GTX 1660: 500–600W (Corsair CX550M, ~$70).

Selection Criteria:

- 80 Plus Bronze certification or higher;

- Semi-modular design for ease of assembly;

- Overvoltage and short-circuit protection.

5. Pros and Cons of the Processor

Pros:

- Energy Efficiency: 65W TDP suits compact PCs and HTPCs;

- Powerful Integrated Graphics — an alternative to budget GPUs;

- Support for Virtualization — useful for software testing.

Cons:

- Outdated Platform: lacks support for DDR4, PCIe 4.0, USB 3.2 Gen 2;

- Limited Upgrade Options: no modern processors for LGA1150;

- Price on the Secondary Market: ~$100–150 for used ones, which is pricey for a 10-year-old CPU.

6. Use Case Scenarios

Office and Multimedia

The processor easily handles office applications (Word, Excel), a browser with 10+ tabs, and 4K video (thanks to the HEVC decoder).

Light Gaming

Iris Pro 6200 can manage:

- Dota 2 (720p, medium settings, 40-50 FPS);

- GTA V (720p, low settings, 30 FPS).

Home Server or NAS

Low power consumption and virtualization support make it a candidate for a server based on Proxmox or TrueNAS.

7. Comparison with Competitors

AMD A10-7850K (Kaveri)

- Pros of AMD: cheaper, more affordable motherboards.

- Cons: weaker in multi-threaded tasks (4 cores without HT), Radeon R7 graphics are inferior to Iris Pro.

Intel Core i5-5675C

A close "relative" with similar graphics but 4 cores/4 threads. In multitasking, the i7-5775R outperforms by 25-30%.

Modern Analogues (2025)

Even the budget Intel Core i3-14100 (4 cores/8 threads, 12th generation) surpasses the i7-5775R by 60-70% in multi-threading and supports DDR5.

8. Assembly Tips

- Cooler: The BOX version is sufficient for basic tasks, but for quiet operation, choose a tower cooler (Deepcool Gammaxx 400, ~$25);

- Storage: SSD SATA 6 Gb/s (Crucial MX500 1TB, ~$80) — the minimum for a responsive system;

- Case: Mini-ITX is suitable for HTPC (Fractal Design Node 304, ~$100).

Example Build (without GPU):

- Motherboard: ASUS H97I-PLUS (~$80 used);

- Memory: 16 GB DDR3L-1600 (~$45);

- Storage: Kingston A400 480 GB (~$35);

- PSU: be quiet! SFX Power 3 400W (~$70).

9. Final Conclusion: Who is the i7-5775R Suitable For?

This processor should be considered only in specific scenarios:

- Retro Build Enthusiasts — for hardware experiments from the 2010s;

- Budget HTPCs — a low-power media center for 4K content;

- Office PCs — if you have a compatible motherboard and memory.

Do not choose the i7-5775R if:

- A modern gaming system is needed;

- Support for DDR4 or PCIe 4.0 is required;

- A long-term upgrade perspective is important.

Price: For a new processor (if it is somehow found in stock) — $150–200, but it is wiser to look for used ones for $80–120.

Conclusion

The Intel Core i7-5775R is an example of a "workhorse" that remains useful in niche projects after 10 years. Its strength lies in the balance between performance and energy efficiency, but it is already unsuitable for modern tasks. If you have compatible components on hand or wish to build a nostalgic PC — this CPU is worth considering. In other cases, it would be better to look at modern budget processors like AMD Ryzen 5 7500F or Intel Core i3-14100.
