Intel Core i5-9400F (6C/6T, 2.90 GHz, 9MB Cache, LGA1151, 65W), TRAY

This parameter determines the CPU socket on the mother board for which the particular CPU is intended. Physically the CPU can be placed in the compliant socket only. Prior to buying the CPU you should verify that your motherboard has the corresponding CPU socket.

The CPU type indicates the CPU models set by the manufacturer based upon their capacity and the application features. For Intel CPUs these are starting from most powerful - Core i7, Core i5, Core i3, Core 2 Quad, Core 2 Duo, Pentium Dual Core and Celeron models.

The CPU manufacturer Intel has introduced the system of numbering of CPUs that allows accurate identification of each CPU manufactured by Intel and its compatibility with motherboards. Prior to buying the CPU you verify the support of this CPU number on the website of the motherboard manufacturer.

The number of the CPU cores is the parameter of the operation speed and stability. CPU with two or more cores can handle tasks in parallel, thus achieving extra high-speed and the system stability. Prior to buying a multi-core CPU you should verify if the motherboard supports this type of CPU.

The CPU clock frequency is the index of operation speed that determines the number of calculation cycles that the CPU can perform per second. Higher clock frequency means higher operation speed.

Small, fast memory that stores the copies of the data memories from the main memory that are most often used by the computer applications. It is like a temporary storage or data buffer between the CPU and RAM.

It shows with how big numbers it can operate within a single cycle. It is advisable to have this index at the level of 512 KB or at least 256 KB.
