Intel Celeron G5905: A Budget Processor for Basic Tasks in 2025

Current as of April 2025

1. Key Specifications: Architecture, Performance, and Key Features

Comet Lake Architecture and 14nm Process Technology

The Intel Celeron G5905, launched in 2020, is based on Comet Lake architecture and manufactured using 14nm technology. Despite being outdated by 2025 (with modern Intel processors utilizing 7nm and 10nm nodes), it remains popular in the budget segment due to its low cost and energy efficiency.

Cores and Threads:

- 2 cores, 2 threads.

- Base frequency: 3.5 GHz (no turbo boost).

Graphics:

- Integrated Intel UHD Graphics 610 with a base frequency of 350 MHz.

Performance:

- Geekbench 6: 724 points (single-core test), 1242 points (multi-core test).

- For comparison: AMD Athlon 3000G (2 cores/4 threads) scores around ~800/1500 points in Geekbench 6.

TDP: 58W — modest power consumption, making cooling easier.

Cache: 4MB L3 cache.

Key Feature: Price. In 2025, the processor costs $45–55 (new), making it one of the most affordable solutions on the market.

2. Compatible Motherboards: Sockets and Chipsets

LGA 1200 Socket and Budget Chipsets

The Celeron G5905 uses the LGA 1200 socket, compatible with chipset series 400 and 500:

- H410/B460/H470/Z490 (for Comet Lake).

- H510/B560/H570/Z590 (compatible after BIOS update).

Selection Recommendations:

- For Office PCs: Motherboards based on H410/H510 (e.g., ASUS Prime H410M-K, $60–70). They lack overclocking features but support basic needs.

- For Upgrades: B560 chipset boards (e.g., Gigabyte B560M DS3H, $90–100) allow for DDR4-2933 memory and have PCIe 4.0 support.

Important: Ensure the motherboard's BIOS is updated to a version that supports Comet Lake.

3. Supported Memory Types

DDR4-2666 in Dual-Channel Mode

The Celeron G5905 works with DDR4-2666 memory (maximum capacity — 128GB). DDR5 is not supported.

Recommendations:

- Optimal configuration: 2 modules of 8GB (e.g., Crucial DDR4-2666, $30 for a kit).

- For office tasks, 8GB is sufficient, but 16GB will provide headroom for multitasking.

Limitation: Memory frequencies above 2666MHz will not be utilized without Z-series chipsets.

4. Power Supply Units: Calculations and Recommendations

Minimum Power, Maximum Savings

With a TDP of 58W and no discrete graphics card, a system based on the G5905 consumes ~100–120W (considering storage, memory, and peripherals).

Tips:

- Basic Option: Power supply of 300–400W (e.g., EVGA 400 W1, $35).

- With Headroom for Upgrades: 500W (Be Quiet! System Power 10, $55), if planning to install a GTX 1650-level graphics card.

Important: Choose a power supply with an 80+ Bronze certification or higher for stability.

5. Pros and Cons of Celeron G5905

Strengths:

- Price: One of the cheapest processors on the market.

- Energy Efficiency: Suitable for compact builds.

- Integrated Graphics: Allows operation without a graphics card.

Weaknesses:

- 2 Cores/2 Threads: Multitasking is limited (e.g., running a browser with 10+ tabs and office applications may cause lag).

- Outdated Architecture: Lags behind even budget AMD Athlon in multi-threaded tasks.

- No PCIe 4.0/5.0 Support: Limits speeds for storage and graphics cards.

6. Use Cases: Where G5905 is Relevant in 2025

Office Tasks and Multimedia

- Documents, Browsing, Zoom: The processor handles basic applications.

- Video Playback: 4K support via HDMI 1.4 (limited to 30Hz) and H.265.

- Light Gaming: Minecraft, Dota 2 on low settings (UHD 610 achieves ~25–30 FPS at Full HD).

Practical Example:

Home theater build:

- Celeron G5905 + 8GB DDR4 + 256GB SSD.

- Power consumption — 25W at idle, noise — less than 20 dB.

7. Comparison with Competitors

AMD Athlon 3000G vs Intel Celeron G5905

- Athlon 3000G (2 cores/4 threads, Vega 3): Better in multi-threaded tasks (+20% in Geekbench 6 Multi Core) and gaming (Vega 3 is 30% faster than UHD 610). Price: $60–70.

- Intel Pentium Gold G6400 (2 cores/4 threads, UHD 610): Closest Intel alternative but more expensive ($75–85).

Conclusion: The Celeron G5905 only wins in terms of price. If the budget is extremely tight, the Intel choice is justified. Otherwise, the Athlon 3000G is preferable.

8. Practical Assembly Tips

Budget Build

- Motherboard: ASRock H510M-HDV ($65).

- Memory: Patriot Signature Line 8GB DDR4-2666 ($15).

- Storage: Kingston A400 240GB SSD ($25).

- Power Supply: EVGA 450 BT ($40).

- Case: Cooler Master MasterBox Q300L ($50).

Total Cost: $240–250 (excluding OS and monitor).

Advice: Don't skimp on the SSD — it will speed up system performance.

9. Final Conclusion: Who is the Celeron G5905 Suitable For?

This processor is a choice for those who:

- Are building a PC for office work, studying, or browsing with a budget of under $300.

- Require a quiet and compact system (e.g., for a media center).

- Plan to use the PC as a temporary solution before an upgrade.

Why is it still relevant in 2025? Despite modest performance, its price and minimal cooling requirements make it ideal for niche tasks. However, for gaming, video editing, or working with "heavy" applications, more modern solutions should be considered.

Conclusion: The Intel Celeron G5905 is a "workhorse" example for non-demanding users. It won't wow with speed but will provide stability and savings, remaining viable even five years post-release.
