What is the difference between a PCI and AGP card?
PCI (Peripheral Component Interconnect) and AGP (Accelerated Graphics Port) are two different technologies used to connect expansion cards – such as video, sound, and graphics cards – to your PC. The main difference between the two is speed, particularly when it comes to processing graphics.
How does AGP improve the overall performance of a PC?
AGP improves the overall performance of a PC in several ways: 1. Graphics operations are faster because they don’t have to share bus bandwidth with other peripherals. 2. Peripheral devices are also faster because they don’t have to share the PCI bus with the bandwidth intensive graphics operations.
What is an Accelerated Graphics Port (AGP)?
An Accelerated Graphics Port (AGP) is a point to point channel that is used for high-speed video output. This port is used to connect graphic cards to a computer’s motherboard.
What is bus AGP?
INTEL developed bus AGP especially for those. The speed of this bus is of 66 MHz in all the versions. It is able by DMA (direct Memory Access) to take the control of the memory for the direct transfer of information. This characteristic is also established in bus PCI. The specifications of INTEL propose 3 operating modes:
What is an AGP (Accelerated Graphics Port)?
The growth of the bandwidth needs of video cards coupled with the fact that all cards in the PCI slots share the same bus led to the development of a new slot that is for video cards only; this is the AGP (Accelerated Graphics Port).
What is an AGP slot in a video card?
The AGP slot also allowed video cards to directly access a portion of your system memory to read textures. These advantages allowed AGP video cards to perform a lot faster compared to their PCI counterparts.
