Socket FM1 is a type of processor socket that was developed by AMD for use with its Llano and Trinity APUs (Accelerated Processing Units). These APUs combine a central processing unit (CPU) with a graphics processing unit (GPU) on the same chip, and Socket FM1 was designed to provide a compatible interface for these combined processors.
The socket has 905 pins and is compatible with a variety of motherboards that support the FM1 socket. It was first released in 2011 and was used in a number of desktop and laptop computers.
Key features of Socket FM1:
- Compatibility with AMD A-series and E-series APUs
- Support for dual-channel DDR3 memory
- Support for AMD’s Turbo Core technology, which allows for automatic overclocking of the processor
- Support for AMD’s HyperTransport technology, which allows for faster communication between the CPU and other components in the system.
One of the main advantages of Socket FM1 is that it allows for a more compact and energy-efficient computer design, as the CPU and GPU are integrated on the same chip. This can be beneficial for laptops and other mobile devices, as well as for small form factor desktop computers.

Best Processor for FM1
When it comes to the best FM1 CPU, the AMD A8-3870K stands out as the top choice. This processor was released in 2011 as part of the A-series Llano APU lineup, and it offers a solid balance of performance and value.
The A8-3870K is a quad-core processor with a base clock speed of 3.0GHz and a maximum turbo frequency of 3.4GHz. It also features an integrated Radeon HD 6550D graphics processor with 400 stream processors, which provides decent performance for gaming and other graphics-intensive tasks.
One of the key benefits of the A8-3870K is its unlocked multiplier, which enables easy overclocking and the ability to boost the performance of the processor. In addition, supports dual-channel DDR3 memory, which can deliver a significant performance boost in certain applications.
In terms of value, the A8-3870K is relatively affordable and offers a good balance of performance and price.
The AMD A8-3870K is a good choice for budget-friendly systems with balanced CPU and GPU performance. But it’s not the most powerful processor available. If you’re looking for more powerful and newer technology, FM1 socket may not be the best option. Consider newer sockets such as AM4 and LGA 1200 that offer better performance and features.

since when is the unit for tdp Hz as in socket FM1?
Two wishes and a hint:
As it is a bitly tricky to make it sortable in web, especially several colums/rows differently like in limbas, Base, access, …. a dta or csv download with units in the upper and plain values below, for each socket or complete, would be nice.
To find / compare computing power regardles generations and sokets a flop or the like info is helpfull and also storing & querying in DBs.
Hint: use always same units and dont mix SI exponentials MB kB or x2. Split the last in a separate field as per core, thread …
Just found a nice bogus in Libre calc sorting TDP intermixed 123, 133, 145, 30, 40, 50 … obviously due to the appended W each value in the cells.
Otherwise a nice work.
