The CPU talks to the RAM via the Front Side Bus (FSB.) The FSB is controlled by the Northbridge processor built into the computer's main board (Motherboard.) The Northbridge also manages your PCI_Express 16x slots, and integrated video cards.
CPU front side bus RAM clock rate
The two primary types of bus lines on the motherboard that run between the CPU and the RAM sockets are the address bus and the data bus. The address bus is responsible for carrying the addresses of the data being accessed, allowing the CPU to specify which memory location it wants to read from or write to. The data bus, on the other hand, transfers the actual data between the CPU and the RAM. Together, these buses facilitate communication and data exchange between these critical components.
Your data busses sends information from component to component i.e. your FSB (front side bus)/system bus/internal bus communicates between your CPU and RAM, the faster it runs, the faster information is moved between your RAM and CPU giving your CPU quicker access to that data.
to conserve the battery life by reducing the bus speed between the CPU and RAM
Address Bus - Transmits memory addresses between the CPU and RAM.Data Bus - The bus that transfers data between CPU and RAM. Expansion Bus - The bus to which add-on adapter cards are connected in order to enhance the functionality on the PC. Video - The bus that transmits display information between the CPU and video circuitry.
the CPU bus is the connection between the motherboard and the CPU. All data flows through different data bus.
The northbridge chip. The northbridge connects to the CPU through the front-side bus (FSB) and connects to the RAM through the memory bus.
A memory management unit (MMU) is a small device between CPU and RAM recalculating the actual memory address, for example to provide an abstraction of virtual memory or other tasks.
Programs from the hard drive are sent to the RAM for quick access and from there are sent to either the CPU or GPU, depending on whether the operation is calculational or some type of video processing.
In Intel systems- the Front Side Bus In AMD systems- Hyper Transport
The system bus speed refers to the rate at which data is transferred between the CPU and other components of the computer, such as RAM and peripheral devices. It is typically measured in megahertz (MHz) or gigahertz (GHz). The specific bus speed can vary based on the motherboard and CPU architecture. To find the exact bus speed for a particular system, you would need to consult the specifications of the motherboard or CPU.
The central processing unit (CPU) of a computer is interfaced to the random access memory (RAM) via the front side bus (FSB). Additionally the Northbridge is/can also be interfaced with the CPU through FSBs.
