AMD Ryzen 5 3400G: Budget APU for Versatile Tasks in 2025
Updated: April 2025
1. Key Specifications: Architecture and Main Features
The AMD Ryzen 5 3400G processor, released in 2019, remains a popular choice for budget builds due to its successful combination of CPU and GPU on a single chip.
Architecture and Process Technology
- Codename: Picasso.
- Architecture: Zen+ (optimized version of Zen 1).
- Process Technology: 12 nm (GlobalFoundries).
- Cores/Threads: 4/8.
- Frequencies: 3.7 GHz (base) / 4.2 GHz (turbo).
- Cache: L2 – 2 MB, L3 – 4 MB.
- TDP: 65 W.
- Integrated Graphics: Radeon Vega 11 (704 stream processors, clock speed up to 1400 MHz).
Performance
- Geekbench 6: 1170 (single-threaded), 3331 (multi-threaded).
- Integrated Graphics: Comparable to entry-level discrete graphics cards like the NVIDIA GT 1030. For example, in CS:GO at medium settings (1080p), it yields 60-80 FPS, and in Fortnite (720p, Low) – around 50-60 FPS.
Key Features
- APU (Accelerated Processing Unit): Integration of CPU and GPU eliminates the need to purchase a separate graphics card.
- Precision Boost 2: Automatic overclocking based on workload and temperature.
- Energy Efficiency: Low thermal output allows for the use of compact cases.
2. Compatible Motherboards: Sockets and Chipsets
Socket: AM4 — a universal AMD platform supporting multiple generations of processors.
Recommended Chipsets:
- B450: Optimal choice (e.g., MSI B450 Tomahawk Max). Support for overclocking, PCIe 3.0, USB 3.1. Price: $70-100.
- A320: Budget option (ASRock A320M-HDV). Suitable for basic builds without overclocking. Price: $50-70.
- X470: For enthusiasts (ASUS ROG Strix X470-F), but excessive for the 3400G.
Selection Tips:
- BIOS Update: Motherboards from 2018-2019 may require a BIOS update to work with the 3400G.
- VRM Cooling: Even with a TDP of 65 W, it's advisable to choose a motherboard with heatsinks on the MOSFETs, e.g., Gigabyte B450 Aorus M.
3. Supported Memory: DDR4 and Tuning Tips
- Memory Type: Only DDR4 (DDR5 not supported).
- Modes: Dual-channel (mandatory for maximizing Vega 11 performance).
- Frequencies: Up to 2933 MHz (officially), although many boards allow overclocking to 3200-3400 MHz.
Recommendations:
- At least 8 GB (2×4 GB) for gaming. For video editing or graphics work — 16 GB (2×8 GB).
- Examples: Kingston HyperX Fury 3200 MHz (around $50 for 16 GB).
4. Power Supplies: Power Calculation
- Processor TDP: 65 W.
- Recommended PSU:
- Without discrete graphics card: 400-450 W (e.g., be quiet! System Power 9 — $55).
- With graphics card (e.g., GTX 1660): 500-550 W (EVGA 500 BR — $60).
Tips:
- Don’t skimp on the PSU: at least 80 Plus Bronze certification.
- For quiet operation: models with passive mode up to 50% load (Corsair CX550M).
5. Pros and Cons of the Ryzen 5 3400G
Pros:
- Best integrated graphics among budget CPUs.
- Low power consumption and heat generation.
- Price: $120-150 (new, 2025).
- Supports multithreading (SMT).
Cons:
- Only 4 cores: weak in multitasking compared to 6-core Ryzen 5 5600G.
- No PCIe 4.0 support.
- Limited L3 cache (4 MB).
6. Use Cases
- Office and Multimedia: Document work, 4K video, streaming.
- Light Gaming: Indie games, esports titles (Dota 2, Overwatch 2).
- Home Server/NAS: Thanks to low TDP.
Real Experience:
- 1080p video editing in DaVinci Resolve is possible, but rendering will take about 30% longer than with the Ryzen 5 5600G.
- In GTA V (1080p, medium settings) — 45-55 FPS.
7. Comparison with Competitors
- AMD Ryzen 5 5600G (2021): 6 cores/12 threads, Vega 7. 40% faster in multithreaded tasks. Price: $180-200.
- Intel Core i3-12100 (2022): 4 cores/8 threads, UHD 730. Weaker in graphics but stronger in single-threaded tasks. Price: $130.
- Ryzen 5 2400G (2018): Vega 11, but based on Zen 1. About 15% slower in CPU tasks.
8. Practical Assembly Tips
1. SSD is a Must: Kingston A2000 500 GB ($45) will speed up system loading and performance.
2. Dual-channel Memory: 2×8 GB 3200 MHz is ideal.
3. Cooling: The boxed cooler is sufficient, but for quiet operation — Arctic Freezer 34 ($35).
4. Motherboard with HDMI 2.0: For outputting 4K at 60 Hz (e.g., ASUS Prime B450M-A II).
9. Final Conclusion: Who is the Ryzen 5 3400G Suitable For?
This processor is an ideal choice for:
- Budget PCs: When there is no money for a dedicated graphics card.
- Office systems: High energy efficiency and reliability.
- High-tech enthusiasts: As a temporary solution before an upgrade.
Why in 2025?
Despite its age, the 3400G remains relevant due to its low price and unique graphics. However, for modern AAA games or heavy editing, it's better to add a discrete graphics card or choose a 6-core APU.
Target Audience: Students, office workers, casual gamers. If your budget is limited to $300-400 for the entire build — the 3400G is your option.
