AMD is introducing the new AM1 platform. This platform is built to address a low-budget, sub $400 computer market segment.
The APUs that go into the AM1 systems are SoCs (System on a Chip), and the majority will come as an APU and motherboard combo. This is to be known as a "System in a Socket." On the motherboards themselves, users might read the socket name FS1b, but the Kabini APU, together with a motherboard with an FS1b socket, will be known as the AM1 platform.
The Kabini APUs carry most of the computing hardware, including up to four "Jaguar" CPU cores, the GCN cores, as well as the memory controller (which can address up to 16 GB of DDR3-1600 memory) and all the remaining chipset parts. They have support for up to two SATA3 ports, two USB 3.0 ports, eight USB 2.0 ports, DisplayPort, HDMI, and VGA ports. These chips will be marketed under the Athlon and Sempron names.
Despite that the APUs will come in motherboards, the platform will still be upgradeable. The APUs can simply be removed and replaced with another, more powerful unit that fits in the same socket.
The APU+ motherboard AM1 combinations will have starting prices of about $60. As of this writing, the company has not yet announced specific models or configurations.
