Benefits of AGP
Accelerated Graphics Port, commonly known as AGP is a popular interface specification based on PCI. It was designed due to the high demand of 3-D imaging and graphics. Instead of using the PCU to improve graphics, make use of accelerate graphic points since it has a dedicated channel to ensure the graphic card has direct access to the main memory. AGP supports two faster modes, with 1.07 GBps and 533MBps.
1. Peak Bandwidth
AGP has higher bandwidth than your traditional PCU bus as a result of sideband dressing, data transfers, and pipelining that usually occur of both ends of the clock. In addition to that, AGP allows for direct implementation of texture features from main memory. In other words, it allows high-speed access to main memory, instead of compelling it to load the data into the local system.
2. Less congestion
The PCI application attaches itself to a variety of devices, such as LAN chips, video capture systems, and disk controls. On the other hand, AGP operates independent from, or alongside most features on PCI. In addition to that, CPU can access system memory alongside AGP memory.
3. Balances PC performance
With AGP, users enjoy improved PC performance. The processor can undertake a number of activities whereas the PCI bus is retrieving texture data from the system memory.
4. High performance
Another benefit of AGP is its capability to use memory efficiently instead of demanding VRAM for better performance. However, no one expected VRAM prices to increase. Today, graphic cards have more RAM than desktop computers and have a developed system, as well as reliable memory.
The main challenge in running functionality tests was determining the required clock rates. For instance, modern AGP cards only support 4x and 8x modes. Most motherboard often auto-detect this specifications and unfortunately there is no room for modifications whatsoever.
