AMD Processors

AMD is Intel’s largest rival in computer processors. Anyone buying a processor should research all models and vendors. Table 3.4 lists the AMD processor families.

TABLE 3.4 AMD processor families

Processor family



Multi-core (4-, 6-, or 8-core) high-performance desktop processor.

Phenom II

Multi-core (2, 3, 4, or 6 cores in a single package) high-end desktop for HD support, multimedia creation and editing, gaming, and virtualization. Supports 32- and 64-bit computing, 3DNow!, SSE, SSE2, SSE3, SSE4a, HyperTransport, and Direct Connect technologies.

Athlon II/Mobile/ and Athlon APU

Multi-core (2-, 3-, or 4-core) desktop/mobile processor for productivity, photos, and music.

Sempron APU/Mobile

Lower-cost, low noise, low heat desktop/notebook processor for basic productivity, email, and web browsing or in a home theater computer.

A-series APU/Mobile

Multi-core (2-, 3-, or 4-core) high-performance processor with integrated GPU.

Turion II

Single- or dual-core notebook processor.

Processor sockets are also called zero insertion force (ZIF) sockets; they come in different sizes. A processor socket accepts one or more specific processor models. The socket has a small lever to the side that, when lifted, brings the processor slightly up and out of the socket holes. When installing a processor, the CPU is aligned over the holes and the lever is depressed to bring the processor pins into the slot with equal force on all the pins. In Figure 3.17, notice the lever beside the socket that is used to lift the metal cover so the CPU can be installed into the socket. Table 3.5 lists the commonly used Intel and AMD CPU sockets and is a good study table for the A+ certification.
