Max. frequency in Turbo Boost mode
Max Turbo Frequency is the maximum single-core frequency that the processor is capable of running using Intel technology® Turbo Boost and, if available, Intel technology® Turbo Boost Max 3.0 and Intel® Thermal Velocity Boost. Frequency is usually measured in gigahertz (GHz) or billions of cycles per second.
|
2.26 GHz |
|
Base CPU frequency
The processor’s base frequency describes the speed at which the processor’s transistors turn on and off. The base frequency of the processor is the operating point at which the TDP is determined. Frequency is usually measured in gigahertz (GHz) or billions of cycles per second.
|
1.87 GHz |
|
Cache
The processor cache is an area of fast memory located on the processor. Intel® Smart Cache refers to an architecture that allows all cores to dynamically share access to the last level cache.

Tire speed
A bus is a subsystem that transfers data between computer components or between computers. Types include front-end bus (FSB), which transfers data between the CPU and the memory controller hub; direct media interface (DMI), which is a point-to-point connection between the Intel integrated memory controller and the Intel I/O controller hub on the computer motherboard; and Quick Path Interconnect (QPI), which is a point-to-point connection between the CPU and the on-chip memory controller.
