Intel Celeron G1620T: Budget Processor for Basic Tasks in 2025
Updated: April 2025
Key Features: Modest Performance and Energy Efficiency
The Intel Celeron G1620T processor, released in 2013, belongs to the Ivy Bridge architecture (3rd generation Core). Despite its age, it remains relevant in niche scenarios due to its low power consumption and affordability.
Manufacturing Process and Architecture:
- 22 nm technology — outdated by 2025 standards but ensures low heat generation.
- 2 cores / 2 threads — basic multitasking for office applications.
- L3 cache 2 MB — minimal capacity for simple computations.
- Integrated Intel HD graphics (GT1) — supports resolutions up to 1080p but struggles with modern games.
- TDP 35 W — ideal for passive cooling or compact cases.
Performance:
- Geekbench 6: 374 (single-core) / 701 (multi-core) — performance level is close to mid-range smartphones from 2022–2023. It can handle Google Docs, Zoom, and streaming video, but may lag when opening multiple tabs in Chrome.
Key Features:
- Energy efficiency — suitable for NAS or home server use.
- Low cost — a new processor can be found for $25–30 (as of April 2025).
Compatible Motherboards: Searching for Rare Components
The Celeron G1620T uses the LGA 1155 socket, which limits the selection of motherboards to older models.
Chipsets:
- H61, B75, H77, Q77 — support up to 32 GB DDR3 and SATA II/III.
- Examples of models:
- ASUS P8H61-M LX3 Plus (around $50–60 in new condition).
- Gigabyte GA-B75M-D3H (up to $70).
Selection Features:
- Check for USB 3.0 and SATA III ports — this will speed up SSD performance.
- Avoid boards without UEFI support — there may be issues with modern operating systems.
Supported Memory: DDR3 Limitations
The processor works only with DDR3 (up to 1333 MHz).
- Maximum capacity: 32 GB (but 8 GB is sufficient for basic tasks).
- Recommendations:
- Use dual-channel mode (2×4 GB instead of 1×8 GB) for a 10–15% performance boost.
- Avoid high-frequency memory (e.g., 1600 MHz) — the processor won't utilize its potential.
Power Supply Units: Minimum Requirements
Considering the TDP of 35 W and lack of a discrete graphics card:
- A power supply of 300–400 W is sufficient. For example:
- Corsair CX450 (450 W) — $55 (providing headroom for future upgrades).
- EVGA 400W — $40 (basic option).
- For passive systems (media center), a 150 W PSU will even suffice.
Pros and Cons: Who is the Celeron G1620T Relevant For?
Pros:
- Cost: the full setup (CPU + motherboard + RAM) will cost $120–150.
- Low power consumption — savings on electricity bills.
- Quiet operation — suitable for an office or bedroom.
Cons:
- Does not support DDR4/DDR5, NVMe, USB 3.1.
- Weak graphics — cannot handle even Minecraft on medium settings.
- Outdated platform — challenges with upgrading.
Use Cases: Where is G1620T Still Relevant?
1. Office PCs:
- Working with documents, email, and browsing.
- Example: a build for a small business accounting.
2. Home Media Center:
- Streaming video (Netflix, YouTube) via HDMI.
- Software: Kodi, Plex (hardware decoding for H.264).
3. Entry-Level Servers:
- NAS based on OpenMediaVault (2–4 HDDs).
- Router with pfSense software.
Not Suitable For:
- Gaming, video editing, working in Photoshop.
Comparison with Competitors: What to Buy Instead of G1620T?
1. AMD Athlon 3000G (Zen, 14 nm):
- Pros: Vega 3 graphics, DDR4 support.
- Cons: more expensive ($60–70).
- Performance: Geekbench 6 — 450/900.
2. Intel Pentium Gold G6400 (Comet Lake, 14 nm):
- Pros: DDR4, higher IPC.
- Cons: TDP 58 W, price from $80.
Conclusion: The Celeron G1620T wins only in price and energy efficiency.
Practical Assembly Tips
1. Choose an SSD: Kingston A400 (240 GB for $25) will speed up system boot.
2. Case: Mini-ITX (Cooler Master Elite 110) for compactness.
3. Cooling: The stock cooler is sufficient, but for quiet operation, consider the Arctic Alpine 11 ($15).
4. Don’t overpay: Avoid motherboards priced over $70 — it’s not cost-effective.
Final Conclusion: Who Should Consider the Celeron G1620T?
This processor is a choice for:
- Budget build enthusiasts — for example, the "$100 PC" project.
- Business owners needing cheap office computers.
- IT professionals creating test benches or backup systems.
Why in 2025?
The G1620T is not for everyone, but its price and minimalism are justified for niche tasks. If your goal is to save money and not demand the impossible from your PC, this processor can still serve you well. However, for most users, it’s better to consider modern Celerons (such as those from the Alder Lake series) or AMD Athlon.
Prices are valid as of April 2025. The costs reflect new components.
