PCI Express and AGP are graphic video cards that are used to enhance the performance of the computer.
The physical distance between the connector and the bracket in an AGP card is quite large and therefore this is instrumental in allowing any device with small or big cables to be connected with ease to the AGP.
AGP was initially developed by Intel and the ownership was later on transferred.
The speed of data transfer is small and the number of speeds is 4 with the highest being 8x.
Main Differences Between PCI Express and AGP
- While AGP usually deals with the data transfer of graphical and 3D format files alone, the PCI Express can transfer all kinds of data including photos, videos, and documents.
- PCI Express has a huge data transfer speed with the maximum being 16x as this is facilitated by the large bandwidth whereas in AGP the data transferring speed is quite low as their allotted bandwidth is limited.
- The outer card in the case of AGP is a single unit and is all joined to the slot while that of PCI Express is a bunch of isolated components.
- PCI Express cards can fit into slots that are either their correct size or even into bigger slots as the hardware is advanced and has better properties whereas, on the other hand, AGP can only fit into its designated slots.
- The distance between the bracket and connector in AGP is quite large while that in PCI Express is small.
Conclusion
Both AGP and PCI Express could be used by the same user on the same device or within different devices.
The only necessity is that they both can’t be inserted into a single slot.
Depending on all the properties including the speed and data transfer efficiency, a user can choose which of the two would be suitable for them as an individual.
The exterior makeup of both the cards is stark different causing a major difference in their market values.
The quality of the display and the nature of AGP is quite high and is therefore preferred by visual stage performers or for systems that perform many presentations.
