Intel Celeron G5905T: A Budget Processor for Basic Tasks

April 2025

1. Key Features: Architecture and Performance

The Intel Celeron G5905T, released in 2020, belongs to the Comet Lake family and is manufactured using a 14nm process. This dual-core CPU features two threads, a base clock speed of 3.5 GHz (without Turbo Boost), and a TDP of 35W. The integrated Intel UHD Graphics 610 provides basic visualization capabilities, while support for DDR4-2666 memory makes it compatible with most budget builds.

Key Features:

- Low power consumption — ideal for compact PCs.

- Integrated graphics — no need for a separate GPU.

- Supports up to 128GB of RAM (in theory, but rarely utilized in practice).

Performance:

- Geekbench 6: Single-Core — 246, Multi-Core — 392.

- Suitable for light tasks: office applications, browsing, HD video playback.

- In gaming: can run older titles (e.g., Half-Life 2) or 2D indie games at low settings.

2. Compatible Motherboards

The processor uses the LGA 1200 socket, which limits motherboard choices to chipsets H410, B460, H470, Z490.

Selection Recommendations:

- Budget Option: ASRock H410M-HDV ($55–65) — minimal ports but stable performance.

- Future-Proofing: Gigabyte B460M DS3H ($75–85) — supports M.2 NVMe and has more RAM slots.

Important:

- H410/B460 chipsets do not support overclocking (the CPU is locked anyway).

- For upgrades to more powerful Comet Lake processors (e.g., Core i3-10100), it’s better to choose B460.

3. Supported Memory

Celeron G5905T works with DDR4-2666 MHz in dual-channel mode. The maximum capacity is 128GB, but for practical purposes, 8–16GB is sufficient.

Example Modules:

- Patriot Signature Line 8GB DDR4-2666 ($25) — a reliable budget option.

- Crucial 16GB Kit (2x8GB) DDR4-2666 ($50) — optimal for multitasking.

Tip: Avoid memory with frequencies higher than 2666 MHz — the processor doesn’t utilize it.

4. Power Supply Recommendations

With a TDP of 35W, the processor is extremely efficient. However, it’s important to consider the power consumption of other components.

Scenarios:

- Build without a discrete GPU: A 300W PSU (e.g., EVGA 400W, $40).

- With a GPU like the GTX 1650: A 450W PSU (Corsair CX450, $55).

Rule: Don’t skimp on the PSU. Even in budget builds, opt for models with an 80+ Bronze certification.

5. Pros and Cons

Pros:

- Price: the new processor costs about $45–50 (2025).

- Energy efficiency — suitable for HTPCs or office PCs.

- Integrated graphics — saves on GPU purchase.

Cons:

- 2 cores/2 threads — limited multitasking.

- No support for PCIe 4.0 and DDR5.

- Outdated 14nm process — high heat under load.

6. Use Case Scenarios

Who is this processor for?

- Office Tasks: Working with documents, Zoom conferences.

- Multimedia: Watching videos in 1080p, streaming.

- Retro Gaming: Running games from before 2010 (e.g., The Sims 3).

Not Suitable For:

- Video editing, 3D rendering.

- Modern games (even Fortnite at minimum settings may lag).

7. Comparison with Competitors

AMD Athlon 3000G (Price: $60–70):

- 2 cores/4 threads, Vega 3 graphics.

- Better for multithreaded tasks, but more expensive.

Intel Pentium Gold G6400 (Price: $70–80):

- 2 cores/4 threads, 4.0 GHz clock speed.

- Higher performance in single-threaded applications.

Conclusion: The Celeron G5905T is the cheapest but also the weakest in its lineup.

8. Practical Assembly Tips

1. Choose an SSD: Kingston A400 240GB ($30) will speed up system performance.

2. Don’t overspend on cooling — the stock cooler is sufficient.

3. Optimize the budget:

- Motherboard: $60.

- RAM: 8GB — $25.

- Storage: 240GB SSD — $30.

- Case + PSU: $50.

Total: $210–230 without a monitor.

9. Final Conclusion

The Intel Celeron G5905T is ideal for:

- Office PCs — low cost and adequate performance.

- Home Theater PCs — quiet operation and 4K support via HDMI.

- Builds for elderly users — simplicity and reliability.

Why not to choose it:

If future expandability is needed or if planning to work with demanding applications — better to add $20–30 and opt for a Pentium Gold or Athlon 3000G.

Summary: The Celeron G5905T is a "workhorse" for those who value budget over high performance. In 2025, it remains relevant for niche scenarios but clearly falls behind more modern models.
