What is the difference between AGP and PCI?

Category: Slots Tags:

The primary advantage of AGP over PCI is that it provides a dedicated pathway between the slot and the processor rather than sharing the PCI bus. In addition to a lack of contention for the bus, the point-to-point connection allows for higher clock speeds.

AGP also uses sideband addressing, meaning that the address and data buses are separated so the entire packet does not need to be read to get addressing information. This is done by adding eight extra  bits which allows the graphics controller to issue new AGP requests and commands at the same time with other AGP data flowing via the main 32 address/data (AD) lines. This results in improved overall AGP data throughput....

What is the Difference between PCI, PCI-X and PCI-e?

Category: Slots Tags:

PCI-X is the upgraded version of PCI. It differs mainly in the fact that the PCI-X bus is 64-bits wide, and runs at higher frequencies of up to 533MHz, compared to PCI frequency that runs up to 66MHz.

PCI-Express, on the other hand, uses a serial interconnect along a switched bus dedicated exclusively to that slot. PCI-Express has the unique capability of multiplying up individual data lanes, to produce aggregate interconnects that can deliver up to 16 times the bandwidth of a single lane....

What is PCI Express?

Category: Slots Tags:

PCI Express stands for Peripheral Component Interconnect Express. It is also known as PCIe. PCI Express expands on and doubles the data transfer rates of original PCI. PCI Express is a two-way, serial connection that carries data in packets along two pairs of point-to-point data lanes.

PCIe was developed in 2004, it was designed to provide higher performance and bandwidth than PCI or AGP. While some standard PCI slots can still be found on motherboards, many computer users prefer PCI express for graphics cards....

What is the difference between ISA and PCI?

Category: Slots Tags:

ISA is an old technology that has been replaced by PCI, PCIe and so on. ISA slots are usually black, long and the gold contacts are large. PCI slots are light-colored, usually white, shorter and smaller.

What is PCI?

Category: Computing Tags:

PCI (Peripheral Component Interconnect) is a computer bus used for attaching peripheral devices to a computer motherboard. It is the most popular local I/O bus used in today. PCI provides a shared data path between the CPU and peripheral controllers in every computer models, from laptops to mainframes. Developed by the Intel Corporation, PCI first appeared in computers in 1993 and co-existed with the ISA bus for several years. It soon displaced the ISA and VESA local bus and became the standard expansion bus used in PCs. Today, most computers have only PCI slots and one AGP slot for a display adapter.

PCI supports both 32-bit and 64-bit data paths and can run at clock speeds of 33MHz or 66MHz. When implemented at 32 bits and 33 MHz, PCI yields a throughput rate of 133 MBps. PCI also has the ability to support bus mastering. The PCI specification covers the physical size of the bus, including wire spacing, bus timing, electrical characteristics, and protocols. The specification can be purchased from the PCISIG also known as the PCI Special Interest Group....
