The processor family identifies the group or series of CPU models that share a common architecture, design, and performance characteristics. It helps users compare processors across brands and generations by indicating the underlying technology used in the chip.

The physical connector used by a processor to attach to a motherboard or other compatible platform, such as LGA 1151, BGA 1440, Socket AM4, or LGA 1200. This attribute indicates the exact socket designation required for proper CPU installation and compatibility with other hardware components.

The maximum operating frequency of a central processing unit (CPU), expressed in hertz (Hz). This value indicates how many cycles per second the CPU can execute under normal conditions and is useful for comparing performance potential across different models.

The physical size or shape of a storage disk, indicating the dimensions and mounting format used in computers and other devices. Common values include standard sizes such as "3.5" in., "2.5" in., and form‑factor codes like "M.2 2280" or "mSATA". This attribute helps users identify which drives are compatible with a given enclosure, motherboard, or system.

The amount of digital storage available in a device for holding data or program code, expressed as a data size such as megabytes (MB) or gigabytes (GB). It indicates how much information the component can hold at once and is commonly used to describe RAM modules, flash drives, SSDs, and other memory devices.

The maximum data transfer rate supported by the network interface card, expressed in bits per second or common abbreviations such as Gbps or Mbps. This value indicates how fast the device can send and receive data over a wired connection.

The physical connection types that a PC product uses to interface with other devices or peripherals, such as HDMI, USB, Ethernet, DisplayPort, VGA, DVI, SATA, and similar cables or ports. Each value represents one distinct connector or cable type that the product supports for data transfer, video output, power delivery, or networking.

Indicates whether the product is compatible with both USB 2.0 and USB 3.0 interfaces, allowing it to connect to devices that use either standard.

A list of the USB interface versions that a product supports, such as USB 2.0, USB 3.0, USB 3.1, USB 3.2 or combinations like "USB 2.0 & USB 3.0". The values indicate which USB standards are available for connecting peripherals and external devices.
