Socket FM1 – CPU list, features and specifications

CPU list for socket FM1

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.

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.
