TDP: 100W
Unlocked: Yes
+ Pros
- Highest clock speeds
- Works in FM2+ motherboards
- Fastest FM2 CPU
- 384 GPU cores
- Cons
- 100W TDP
- FM2 socket
- Older Richland architecture
The A10-6800K is the best FM2 socket CPU ever made. But here is the key: it works in FM2+ motherboards too, thanks to backward compatibility.
Clock speeds are actually higher than the FM2+ A10 chips. The 4.4 GHz turbo frequency is the highest of any processor in this roundup. Real-world performance is competitive, though the older Richland architecture shows its age in efficiency.
The Radeon HD 8670D integrated graphics have 384 shader cores, fewer than the Kaveri APUs. Gaming performance trails the A10-7850K and 7870K by 15-20%.
At 100W TDP, this chip runs hot. I recommend an aftermarket cooler. The stock cooler struggles to keep temperatures under control under sustained load.
This CPU makes sense only if you find an amazing deal or already own an FM2 motherboard. For FM2+ systems, the newer Kaveri chips are better choices.
Who Should Buy?
Users with FM2 motherboards who want the fastest possible CPU, or anyone who finds an exceptional deal on a used unit.
Who Should Avoid?
Most FM2+ motherboard owners. The Kaveri-based A10-7850K and 7870K offer better efficiency and graphics performance.
Understanding FM2+ Platform Limitations
The FM2+ platform is obsolete. AMD stopped making these processors in 2017. Socket FM2+ launched in 2012 as an update to the original FM2 socket, adding support for newer Kaveri and Carrizo architecture chips.
FM2+ uses DDR3 memory exclusively. No DDR4 support means you are stuck with older, slower RAM. Dual-channel DDR3-2133 is the typical maximum speed.
PCIe support depends on your motherboard chipset. A88X and A87X chipsets offer PCIe 3.0, while A78X and A58X boards are limited to PCIe 2.0. This affects graphics card performance with modern GPUs.
Important: FM2+ motherboards are backward compatible with FM2 CPUs, but FM2+ CPUs will NOT work in FM2 motherboards. The pin layouts are different.
FM2 vs FM2+ Socket Compatibility
Confusion about socket compatibility is common. Here is the simple answer: FM2+ motherboards accept both FM2 and FM2+ processors. FM2 motherboards only accept FM2 processors.
The FM2+ socket has 906 pins. The FM2 socket has 905 pins. That one pin difference prevents FM2+ CPUs from fitting in FM2 motherboards.
Before buying any CPU, check your motherboard manual or manufacturer website for the CPU support list. Some boards require BIOS updates to recognize newer processors.
How to Choose the Best FM2 CPU in 2026?
Solving for Gaming on a Budget: Match CPU to Your GPU
If you have a dedicated graphics card, buy an Athlon X4. The 860K or 870K deliver identical gaming performance to the A10 series while costing less. Integrated graphics go unused when a discrete GPU is present.
Solving for Integrated Graphics: Choose the A10 Series
For systems without a graphics card, the A10-7870K or A10-7850K are your best bets. The Radeon R7 integrated graphics are the strongest available on FM2+, capable of 1080p gaming in older titles and esports games.
Solving for Quiet Operation: Look at TDP Ratings
The A8-7680 at 45W and Athlon X4 845 at 65W run significantly cooler than the 95W-100W Black Edition chips. Lower power means less heat, quieter fans, and smaller power supplies.
Solving for Used Market Purchases
All FM2+ CPUs are discontinued. You will be buying used. Avoid chips that were heavily overclocked by previous owners. Check seller feedback and look for processors pulled from office systems rather than gaming rigs.
Is FM2+ Still Worth It in 2026?
This is the question everyone asks. My honest assessment: only if you already own the motherboard. The performance gains from a $50 FM2+ CPU are real, but a $100 AM4 or LGA 1700 build delivers 3-4x the performance.
I have helped dozens of users make this decision. If your budget is under $100 for the entire upgrade, FM2+ makes sense. Anything above that and you should save for a platform upgrade.
For retro gaming, emulation, and basic computing, FM2+ remains perfectly adequate. Just do not expect to run Cyberpunk 2077 or stream at 1080p60.
