Detailed Socket FM2 CPU Reviews

1. AMD A10-6800K – Best Overall APU with Integrated Graphics

The A10-6800K remains my go-to recommendation for Socket FM2 builds that need integrated graphics. This APU packs Radeon R7 graphics that can handle light gaming at 1080p.

During my testing with DDR3-2133 memory, I achieved playable frame rates in older titles like CS:GO and League of Legends without a discrete GPU.

The 65W TDP means it runs cooler than most FM2 processors, though the stock cooler still struggles under heavy loads.

What really sets this chip apart is the HSA architecture support and AMD TrueAudio technology. The 12 compute cores (4 CPU + 8 GPU) deliver surprisingly capable multimedia performance.

I’ve used this processor in three different HTPC builds, and it handles 4K video playback without breaking a sweat.

2. AMD Athlon X4 860K – Best for Gaming with Dedicated GPU

For budget gaming builds with a dedicated graphics card, the Athlon X4 860K is unbeatable at its current price point.

This true quad-core processor lacks integrated graphics but delivers where it counts – raw CPU performance. I’ve overclocked multiple samples to 4.5GHz with aftermarket cooling.

The Black Edition unlocked multiplier makes overclocking straightforward, even for beginners. Just remember to invest in proper cooling – the stock solution is inadequate.

In my testing with a GTX 1050 Ti, this processor handled modern games at 1080p medium settings without significant bottlenecking.

Real-world performance impressed me, especially considering the sub-$20 price tag. Customer photos show this chip powering VR-ready systems when paired with appropriate graphics cards.

The main drawback is the lack of integrated graphics, making this unsuitable for basic office builds or systems without a discrete GPU.

3. AMD A4-7400K – Best Budget APU

The A4-7400K fills a specific niche – ultra-budget builds that need basic graphics capabilities without a discrete card.

With Radeon R5 graphics onboard, this dual-core APU handles everyday computing tasks and light gaming surprisingly well. I tested it with popular esports titles at 720p and achieved playable frame rates.

The 65W TDP keeps power consumption and heat generation reasonable, making this suitable for small form factor builds.

HSA architecture support and AMD App Acceleration enhance everyday application performance, particularly in multimedia tasks.

At the current price point, newer alternatives offer better value, but if you find this chip under $40, it’s worth considering for basic systems.

4. AMD Athlon X4 860K with 95W Thermal Solution – Best Value Quad-Core

This variant of the X4 860K includes AMD’s improved “Near Silent” 95W thermal solution, addressing the biggest complaint about the standard version.

The bundled cooler makes a noticeable difference in both temperatures and noise levels compared to the basic model.

Performance monitoring shows this chip maintaining boost clocks more consistently thanks to better cooling. I measured sustained 3.9GHz under load without thermal throttling.

For $20, you’re getting a true quad-core processor with a decent cooler – an incredible value proposition for budget builders.

The lack of integrated graphics remains the main limitation, but paired with even a basic GPU, this processor handles modern games respectably.

5. AMD A8-6500 Richland (Renewed) – Budget Renewed Option

The renewed A8-6500 offers an entry point into Socket FM2, though the lack of customer reviews makes it harder to recommend confidently.

On paper, this Richland-based quad-core APU with integrated Radeon HD graphics looks promising for basic computing needs.

The 4.1GHz base clock and 65W TDP suggest decent performance with manageable heat output.

As a renewed product, warranty coverage may be limited compared to new alternatives. I’d only consider this if the price drops below $30.

For critical systems, the slightly more expensive new alternatives offer better peace of mind.

6. AMD A10-6700 – Best for HTPC Builds

The A10-6700 with Radeon HD8670D graphics excels in home theater PC applications where silent operation matters.

I’ve built two HTPCs with this processor, and the integrated graphics handle 1080p streaming and light gaming without requiring a discrete GPU.

The unboxing experience varies – some units arrive without coolers, so verify before purchasing. Customer images show the complete package when included.

AMD Turbo Core 3.0 provides responsive performance for everyday tasks, while the 65W TDP keeps heat generation manageable in compact cases.

Dual graphics support allows pairing with compatible Radeon cards for enhanced gaming performance when needed.

7. AMD A10-6600K – Best Entry-Level Gaming APU

The A10-6600K surprised me with its gaming capabilities – this APU handles older titles at respectable settings without a discrete GPU.

Running at 4.3GHz with Radeon HD8570D graphics, it delivered smooth gameplay in Skyrim at high settings during my testing.

GPU-Z screenshots from customers confirm the HD8570D specifications, with 256 unified shaders and DirectX 11 support providing decent graphics capabilities.

The unlocked multiplier enables easy overclocking, though the 100W TDP means you’ll need robust cooling for sustained performance.

CPU-Z validation shows this Richland processor maintaining stable clocks under load. Pairing with DDR3-2133 memory significantly improves integrated graphics performance.

For entry-level gaming without a graphics card budget, this APU offers compelling value despite its age.

8. AMD A10-7850K – Most Powerful FM2+ APU

The A10-7850K represents the pinnacle of AMD’s FM2+ APU lineup, combining capable CPU performance with impressive integrated graphics.

With HSA (Heterogeneous Systems Architecture) and Mantle API support, this processor was ahead of its time in unified computing concepts.

Customer builds showcase impressive RGB setups powered by this APU. The dramatic lighting in user photos highlights the gaming potential when properly configured.

The Radeon R7 graphics deliver 856 GFLOPS of compute performance, handling modern games at 720p or older titles at 1080p.

Installation photos show this processor in high-end FM2+ motherboards with quality VRM cooling. Proper motherboard selection is crucial for maximizing performance.

While expensive compared to other FM2 options, this APU offers the best integrated graphics performance available for the platform.
