AMD A6-3620: Review and Relevance in 2025
Introduction
The AMD A6-3620 processor, released in 2011, is part of the Llano lineup aimed at the budget segment. Despite its age, it may still be useful for specific tasks in 2025. Let's examine its specifications, compatibility, and use cases in today's reality.
1. Key Specifications
Architecture and Manufacturing Process
The AMD A6-3620 is built on the K10.5 (Husky) architecture using a 32 nm manufacturing process. This hybrid solution integrates 4 CPU cores with the Radeon HD 6530D graphics. The processor frequency is 2.2 GHz (up to 2.5 GHz in Turbo Core mode), with a 4 MB L2 cache.
Performance
According to Geekbench 6 (2025):
- Single-Core: 253 points;
- Multi-Core: 660 points.
For comparison, the modern budget Intel Celeron G6900 (2025) scores around 1200/2400 points. The A6-3620 is suitable only for basic tasks.
Key Features
- Integrated Radeon HD 6530D graphics — 320 stream processors, supports DirectX 11;
- Turbo Core technology — automatic overclocking under load;
- Energy efficiency — TDP of 65 W.
2. Compatible Motherboards
Socket and Chipsets
The processor uses the outdated FM1 socket. Compatible chipsets include:
- A75 — supports USB 3.0, SATA III;
- A55 — only supports SATA II and USB 2.0.
Selection Considerations
As of 2025, new motherboards for FM1 are no longer produced. The only option is to search for remaining stock or the used market. Examples of models include:
- Gigabyte GA-A75M-DS2 (2025 price — $70-90 if found in new condition);
- ASRock A55M-HVS ($60-80).
Tip: Check for the presence of PCIe 2.0 x16 slots for connecting a discrete graphics card.
3. Supported Memory Types
The A6-3620 works with DDR3 (does not support DDR4/DDR5).
- Maximum capacity: 64 GB (theoretically, but in practice, FM1 motherboards rarely support more than 16 GB);
- Frequencies: 1333–1866 MHz (depending on the motherboard).
Recommendations for 2025:
- The optimal choice is 8–16 GB DDR3-1600 (new modules cost $25–50);
- Use dual-channel mode to enhance the performance of integrated graphics.
4. Power Supply Recommendations
With a TDP of 65 W and no discrete graphics card, a PSU of 300–400 W is sufficient. Examples include:
- Corsair CV450 (450 W, $50) — headroom for future upgrades;
- EVGA 400W ($40) — minimum for an office build.
Important: When installing a graphics card (e.g., GTX 1650), choose a PSU rated for 450–500 W.
5. Pros and Cons
Pros:
- Low cost (new processors, if available, — $50–70);
- Integrated graphics for less demanding gaming;
- Energy efficiency.
Cons:
- Outdated platform (DDR3, PCIe 2.0);
- Low performance in multi-threaded tasks;
- Lack of support for modern technologies (AVX, NVMe).
6. Use Cases
Office Tasks
- Working with documents, web browsing, video conferencing.
Example: A build with A6-3620 + 8 GB DDR3 + 240 GB SSD handles Microsoft 365.
Multimedia
- Watching videos at 1080p, streaming.
Limitation: 4K is not supported due to weak graphics.
Gaming
- Older titles: Half-Life 2, CS:GO at low settings (30–40 FPS);
- Indie games: Stardew Valley, Terraria.
7. Comparison with Competitors
Intel Pentium G860 (Sandy Bridge, 2012):
- Single-Core: 290, Multi-Core: 550 (Geekbench 6);
- Price in 2025: $40–60.
Conclusion: The A6-3620 excels in multi-threading but lags in IPC.
AMD Athlon X4 750K (2013):
- Single-Core: 280, Multi-Core: 800;
- Price: $60–80.
Conclusion: More powerful CPU but requires a discrete graphics card.
8. Practical Assembly Tips
1. SSD is a must — Kingston A400 240 GB ($30) will speed up the system.
2. Don't overspend on memory — DDR3 is 4-5 times cheaper than DDR5.
3. Add a graphics card — even a GT 1030 ($110) will improve gaming performance.
4. Cooling — the stock cooler is sufficient, but switching to a Deepcool GAMMAXX 400 ($25) will reduce noise.
9. Final Conclusion: Who is the A6-3620 Suitable For?
This processor is relevant for:
- Budget Office PCs — if a computer is needed for Word/Excel;
- Media Centers — playback of Full HD content;
- Enthusiasts — building a retro system or a test bench.
Why in 2025?
The A6-3620 is a highly niche solution. It should only be considered under strict budget constraints ($150–200 for the entire build) or for specific tasks. For most users, it’s better to choose modern APUs like the AMD Ryzen 3 5300G or Intel Core i3-N305, which offer 3–4 times higher performance for $100–150.
Summary: The A6-3620 is a relic of the past, but in the hands of an enthusiast or for ultra-budget builds, it can still serve a purpose.
