Intel Core i5-5675C Broadwell: Review and Practical Assembly Tips for 2025

(Relevant as of April 2025)

Key Specifications: Architecture, Performance, and Features

The Intel Core i5-5675C processor, released in 2015, remains an interesting solution for specific tasks. Built on the Broadwell architecture with a 14 nm process, it features 4 cores (without Hyper-Threading) and 4 MB of L3 cache. Its TDP is 65W, making it an energy-efficient option.

Key Features:

- Iris Pro Graphics 6200 — integrated graphics with eDRAM (128 MB), which was superior to competitors at the time.

- High single-core performance: Geekbench 6 Single Core — 1317 points.

- Moderate multi-threading: Geekbench 6 Multi Core — 4012 points.

Despite its age, this processor delivers decent performance in basic tasks. For instance, in 2025, it still manages office applications and light photo processing. However, it is inadequate for modern gaming and resource-intensive applications (like Blender or DaVinci Resolve).

Compatible Motherboards: Sockets and Chipsets

The processor uses the LGA1150 socket, which limits the choice of motherboards to outdated models. Supported chipsets include:

- H97 and Z97 — optimal for overclocking (although the i5-5675C has a locked multiplier).

- B85 and H81 — budget options, but with limited functionality (e.g., no RAID support).

Example Models:

- ASUS H97-PRO (around $120-150 for new, if you can find it in stock).

- MSI Z97 Gaming 5 (similarly priced).

Important: In 2025, new boards for LGA1150 are almost no longer produced. Most offerings are used or leftover stock. When purchasing, check the socket condition and the availability of up-to-date BIOS.

Supported Memory Types

The i5-5675C only works with DDR3L (1.35V) and standard DDR3 (1.5V). The maximum frequency is 1600 MHz, with a capacity of up to 32 GB.

Tips:

- Use dual-channel mode (2x8 GB) to boost integrated graphics performance.

- Modern DDR4/DDR5 is incompatible — this is the main upgrade limitation.

Power Supply Recommendations

With a TDP of 65W, the processor does not require a powerful PSU. Even with a discrete graphics card like the NVIDIA GTX 1650, a 450-500W power supply is sufficient.

Examples:

- Corsair CX450 (80 Plus Bronze, $55-65).

- EVGA 500 BQ (semi-modular, $60-70).

Important: Don't skimp on the power supply! Cheap models can damage components due to unstable voltage.

Pros and Cons

Pros:

1. Energy efficiency — suitable for compact PCs and HTPCs.

2. Powerful integrated graphics — for gaming at 720p (e.g., Dota 2 on medium settings).

3. Low cost — in the secondary market (new models, if available, cost $150-200).

Cons:

1. Outdated platform — lacks support for PCIe 4.0, USB 3.2 Gen 2.

2. Limited performance — 4 cores without Hyper-Threading struggle with multitasking.

3. Upgrade difficulties — DDR3 and LGA1150 are no longer relevant.

Use Cases

1. Office tasks and web browsing — ideal for working with documents and browsers.

2. Multimedia — playback of 4K video via HDMI 1.4 (limited to 30 Hz).

3. Casual gaming — CS:GO, Minecraft, indie projects on Iris Pro Graphics.

4. Home servers — due to low power consumption.

Real Experience: Users report that in 2025, the processor handles Netflix 4K streaming, but "chokes" when running Discord and several Chrome tabs simultaneously.

Comparison with Competitors

1. AMD Ryzen 5 2400G (2018):

- Pros: 4 cores/8 threads, Vega 11 (stronger graphics), supports DDR4.

- Cons: Lower single-core performance (~1200 in Geekbench 6).

- Price: $130-160 (used).

2. Intel Core i3-12100 (2023):

- Pros: 4 cores/8 threads, DDR5, PCIe 5.0.

- Cons: No integrated graphics in the base version.

- Price: $140-160 (new).

Conclusion: The i5-5675C falls short against modern counterparts but excels in budget scenarios focused on integrated graphics.

Practical Assembly Tips

1. Look for combos on the secondary market — often sells CPU + motherboard + RAM cheaper.

2. Choose a case with good ventilation — even at low TDP, overheating can reduce lifespan.

3. Add SSD — Kingston A400 480GB ($35) will speed up system performance.

4. Don’t install high-end graphics cards — GTX 1660 Super will be the limit due to PCIe 3.0 x16 restrictions.

Final Conclusion: Who is the i5-5675C For?

This processor is worth considering for:

- Owners of old LGA1150 PCs — as a budget upgrade.

- Enthusiasts of compact builds — for HTPC or mini-PCs.

- Users on a tight budget — needing a PC for basic tasks under $300.

Why this one? Low price, acceptable performance in 2025, and unique Iris Pro graphics that still find application in niche scenarios. However, for gaming and professional tasks, opting for more modern solutions is advisable.
