What is the difference between PCI E3 0 and PIC E2 0?

Hello landlord, the PCI-E specification increases the data transfer rate to 8GHz|8GT S (10GHz was originally envisioned) and maintains backward compatibility with PCI-E, continuing to support signaling mechanisms. Based on this, the unidirectional bandwidth of the PCI-E architecture can be close to 1 GB s for a single channel (X1), and the two-way bandwidth for a sixteen-channel (X16) can reach 32 Gbs. In other words, the bandwidth of PCI-E has doubled again compared to PCI-E, just like the previous PCI-E upgrade to PCI-E.

In the case of the same configuration, the graphics card is only converted from to, which will not cause a big difference.

So don't worry about the graphics card of the motherboard.

And the difference (PCIe3 and PCIe4) is carefully recommended by the installed DIY network, I hope the following information can bring you a reference role. The installed DIY network provides the latest computer configuration list in 2021, which selects a variety of computer configuration lists, and provides a balanced list of configurations, outstanding cost performance, and more user choices, so that players can DIY computer hosts at low prices.

As we all know, AMD X570 and B550 motherboards, including the RX3000 series graphics cards, are the first to support the PCIe protocol, with up to 32GB S bandwidth, which is fully double the bandwidth compared to the current one, and it is also a major selling point of AMD's new platform, but Intel is indifferent and says that PCIe is useless.

Regarding the advantages, AMD has officially popularized science and summarized three technical advantages, as follows:

1. The speed is faster, and the X16 two-way bandwidth reaches 32GB S, which is twice that of PCIe.

2. Backward compatible, PCIe can be compatible with PCIe devices.

There are two differences between and:1. Transmission speed.

The X16 bidirectional bandwidth reaches 32GB s, which is twice as much.

2. The number of supported devices to be connected.

Devices that take advantage of the PCI slot include graphics cards and SSDs, graphics cards can consider ASUS Dual RX5500XT O8G EVO, SSDs recommend Shadowspeed.

Regarding the advantages, AMD has officially popularized science and summarized three technical advantages, as follows:

1. The speed is faster, and the X16 two-way bandwidth reaches 32GB S, which is twice that of PCIe.

2. Backward compatible, PCIe can be compatible with PCIe devices.

And the differences are as follows:1. Transmission rate.

The speed of transferring data is much faster, it can be said that it is twice as fast, and the two-way bandwidth reaches 32 GB per second, while it can only reach 16 GB per second.

2. Bandwidth.

16 Two-way bandwidth reaches 32GB s, which is almost twice that of PCIe.

3. Performance.

It is directly compatible with the device, but it cannot be upwardly compatible, which is commonly referred to as backward compatibility. Shengqiao core is backward compatible to meet the needs of more users; Finally, based on the large bandwidth, you have more connections, and you can connect more devices without worrying about performance degradation.

4. Number of connections.

The bandwidth is one top two more, so it can connect to more devices without worrying about performance degradation. But in fact, if you compare comprehensively, especially in the process of playing games, the highest gap between the two should be about 1%, so in fact, compared to arguing, the improved performance is basically negligible.
