  • Characteristics
    • Speeds

    • Cores

    • Cache size/type

    • Hyperthreading

      Hyperthreading is an Intel proprietary technology that enables two streams of data to run simultaneously on each processor core. To utilize this technology, the operating system and BIOS must both be capable of supporting multiple processors.

    • Virtualization support

    • Architecture (32-bit vs. 64-bit)

    • Integrated GPU

  • Cooling
    • Heat sink

      Typically made from aluminum or copper, heat sinks are designed to transfer heat away from components through conduction.

    • Fans

      Provides air cooling, the most common method of cooling.

    • Thermal paste

      Designed to fill imperfections or gaps between the component and heat sink to promote heat transfer. Pre-existing compound should be cleaned and reapplied any time the heat sink is removed.

    • Liquid-based

      Newest and most efficient method of cooling.
