Intel Core i5-9400 LGA 1151 Boxed Processor with thermal solution, still sealed

The operating frequency of an individual processor core, expressed in hertz (Hz). It indicates how many cycles per second each core can execute and is useful for comparing performance potential across CPU models.

The fundamental operating speed of a graphics processing unit, expressed in hertz (Hz). It indicates the number of cycles per second that the GPU can execute under normal conditions and serves as a baseline for comparing performance across models.

The highest operating frequency that a graphics processing unit can reach during active operation, expressed in hertz (Hz). It indicates the peak performance capability of the GPU under load and helps users compare how fast a graphics component can run beyond its base clock speed.

The largest amount of random‑access memory that a device or component can support, expressed as a digital data size such as megabytes or gigabytes. It indicates the upper limit for active processes and multitasking performance.

The manufacturing process technology used to fabricate a processor, expressed in nanometers (nm). It indicates the size of the transistors and other features on the chip, which influences performance, power consumption, and integration density. The value is typically a numeric measurement such as 14 nm or 28 nm.

The length of time for which the manufacturer guarantees that the product will be free from defects in materials and workmanship, typically expressed in years or months.
