AGP was dominant for a long period of time, but the introduction of PCIe (PCI express) ultimately led to a large decline in popularity, because PCIe speeds were able to outperform AGP and provide a singular slot type for all devices.
AGP在很長一段時間內一直處於主導地位，但是PCIe（PCI Express）的引入最終導致了流行度的大幅下降，因為PCIe的速度能夠超過AGP並為所有設備提供單一的插槽類型。
Motherboards that provide AGP support have a single AGP slot. Several different versions of AGP have been implemented over the years
AGP 1.0 1x Runs at 66 MHz with a data throughput rate of 266 MBps.
AGP 1.0 2x Runs at 66 MHz with a data throughput rate of 533 MBps.
AGP 2.0 4x Runs at 66 MHz with a data throughput rate of 1066 MBps.
AGP 3.0 8x Runs at 66 MHz with a data throughput rate of 2133 MBps.
提供AGP支持的主機板有一個AGP插槽。這些年來，已經實現了AGP的幾種不同版本
AGP 1.0 1x 以66 MHz運行，數據吞吐率為266 MBps。
AGP 1.0 2x 以66 MHz運行，數據吞吐率為533 MBps。
AGP 2.0 4x 以66 MHz運行，數據吞吐率為1066 MBps。
AGP 3.0 8x 以66 MHz運行，數據吞吐率為2133 MBps。
PCI Express (PCIe) Expansion Slots
PCIe (PCI express) began replacing PCI, PCI-X, and AGP by 2005. Five slot sizes are available for PCIe x1, x2, x4, x8, and x16.
PCIe（PCI Express）到2005年開始取代PCI，PCI-X和AGP。PCIe有五個插槽大小可供選擇 x1，x2，x4，x8和x16。
PCIe x1 was designed to replace the old PCI cards for networking, modems, audio, input output, and other needs by connecting to the southbridge.
PCIe x1旨在通過連接到南橋來替代用於網絡，調製解調器，音頻，輸入 輸出和其他需求的舊PCI卡。
It is worth noting that smaller PCIe cards can be placed in larger PCIe slots,
and vice versa. For example, PCIe x2 can be inserted into PCIe x8,
but PCIe x8 cannot be inserted into PCIe x2.
值得注意的是，較小的PCIe卡可以放入較大的PCIe插槽中，反之亦然。例如，PCIe x2可以插入
PCIe x8中，但PCIe x8不能插入PCIe x2中。
There are different versions of PCIe slots. The maximum number of channels
that can be assigned to a card inserted in a slot depends on the version of the card.
PCIe插槽有不同版本。可以為插入插槽中的卡分配的最大通道數取決於卡的版本。
Basic PCIe provides one channel for transmission (x1) with a transmission
rate of 250 MBps. It can also provide multiple transmission channels
(x2, x4, x8, x16, x32).
基本PCIe提供一個通道用於傳輸（x1），傳輸速率為250 MBps。它還可以提供多個傳輸通道
（x2，x4，x8，x16，x32）。
Newer versions of PCIe can transfer data at an even higher rate per lane
