AMD A8-7670K: Budget Processor for Basic Tasks in 2025
An up-to-date analysis of the capabilities and limitations of this outdated APU
Key Specifications: Architecture and Performance
Godaveri Architecture and 28nm Process
The AMD A8-7670K, released in 2015, is built on the Steamroller microarchitecture (codename Godaveri) using a 28nm process. This is a 4-core processor without support for multithreading (4 cores / 4 threads). Its integrated Radeon R7 graphics (384 shader cores) allow it to function without a discrete graphics card in basic tasks.
Performance in 2025
According to Geekbench 6 benchmarks (relevant for 2025):
- Single-Core: 442 points — comparable to Intel Pentium G4560 (2017).
- Multi-Core: 923 points — similar to modern dual-core CPUs, such as Intel Celeron G6900.
Key Features:
- Integrated graphics Radeon R7 (similar to NVIDIA GT 730).
- Unlocked multiplier for overclocking (Turbo Core support up to 3.9 GHz).
- Low cost: a new processor can be found for $50–70 (remaining stock).
Compatible Motherboards
FM2+ Socket and Chipsets
The A8-7670K uses the outdated FM2+ socket, compatible only with the following chipsets:
- A88X (best option: supports PCIe 3.0, overclocking).
- A78, A68H (basic features, no overclocking).
Example Boards:
- ASUS A88XM-Plus (price in 2025: $60–80 for new, if still available).
- Gigabyte GA-F2A88XM-D3H.
Selection Tips:
- Due to the age of FM2+, new boards are rarely produced. Look for old stock from small vendors or consider used options.
- Make sure to update the BIOS for compatibility with the A8-7670K.
Supported Memory: Only DDR3
The processor works exclusively with DDR3-2133 MHz (dual-channel mode). Attempts to install DDR4 or DDR5 will result in incompatibility.
Recommendations:
- Use two modules (for example, 2×4 GB) to activate dual-channel mode.
- Maximum capacity: 64 GB, but for this CPU 8–16 GB is sufficient.
Power Supply: Power Calculation
With a TDP of 95W and integrated graphics, the minimum power supply wattage is:
- 400–450W (with a reserve for a discrete graphics card like the GTX 1650).
- 300W is enough if only using integrated graphics.
Example PSUs:
- EVGA 450 BR (450W, $45) — for systems with discrete graphics.
- Be Quiet! System Power 10 (350W, $40) — for office builds.
Pros and Cons of the AMD A8-7670K
Advantages:
- Low Price: cheaper than modern Celeron/Pentium processors.
- Integrated Graphics: suitable for HD video and light gaming (e.g., Dota 2 on low settings).
- Overclocking: potential for enthusiasts.
Disadvantages:
- Outdated Architecture: 40–50% IPC lag compared to Ryzen 3 from 2025.
- High Power Consumption: 95W compared to 35–65W of modern alternatives.
- No support for DDR4/NVMe: limits system speed.
Use Cases
1. Office Tasks and Multimedia
- Working with documents, browsers, YouTube (1080p).
- Playing 4K video through HDMI 1.4 (limited to 30Hz).
2. Light Gaming
- CS:GO: 40–50 FPS (720p, low settings).
- GTA V: 25–30 FPS (720p).
3. Home Server or HTPC
- Low-power PC for file storage or content streaming.
Comparison with Competitors
Intel Pentium Gold G6400 (2020, $70 in 2025):
- + Supports DDR4, PCIe 3.0.
- + Better single-threaded performance (Geekbench 6 SC: 580).
- - No integrated graphics level of Radeon R7.
AMD Ryzen 3 3200G (2019, $90–100):
- + Zen+ architecture (12nm), supports DDR4-2933.
- + Vega 8 graphics (30% faster than Radeon R7).
Practical Assembly Tips
1. SSD is a must: A SATA SSD (e.g., Kingston A400, 240 GB, $25) will speed up the system.
2. Don’t overpay for a graphics card: GTX 1650 or RX 6400 is the maximum to balance with the CPU.
3. Cooling: The stock cooler will suffice, but for overclocking choose a Deepcool Gammaxx 400 ($20).
4. Motherboard: Look for models with USB 3.0 and SATA III for SSDs.
Final Verdict: Who is the A8-7670K Suitable For?
This processor is relevant for:
- Budget Builds: if you need a PC for $150–200 for internet and office tasks.
- Enthusiast Hobbyists: experimenting with overclocking on old hardware.
- Temporary Solutions: for instance, replacing a burned-out CPU in an old PC.
Why you shouldn't buy it in 2025:
- Modern Pentium Gold and Ryzen 3 offer better price-to-performance ratios.
- Lack of DDR4 and NVMe support makes the system outdated.
Final Verdict: The AMD A8-7670K is a relic of the past that may still serve in very limited scenarios. It should only be considered under a strict budget or as a temporary solution. For any serious tasks, it’s better to choose budget processors from 2023–2025.
