The difference between PCI Express 2 0 16X and PCI E 16X What do they mean in detail

Express 16X graphics cards cannot be plugged into PCI-E 16X slots.

A 16x graphics card can be plugged into a PCI Express 16x slot.

You can see the graphics card as being an upgraded version, which means that theoretically it will be faster, and the two-way data transfer will be smoother or something.

Pip products, including software or something, remember that they are backward compatible, right, so the upgraded version, as long as the same specifications, can generally accept the old version of the card, or software.

PCI-E is truly a double specification compared to the current one:

Doubling the bandwidth: The bandwidth of a single-channel PCI-E X1 has been increased to 500MB S, which is 1GB S in both directions.

Doubling of channels: The graphics card interface standard is upgraded to PCI-E x32, and the bandwidth can reach 32GbS.

Double the slots: Chipset The motherboard should have two PCI-E x32 slots by default;

Double the power: The current PCI-E slot can deliver up to 75W, and the version may be increased to over 200W, which is uncertain at this time.

Upstairs is misleading!

1.Yes. 2.Yes.

Because the slot specifications haven't changed.

3.The difference is in performance and power supply issues. See link.

There is a difference in the specifications... The details can be encyclopedia... But it makes no difference at all ... Sockets don't affect performance and usage...

First, the characteristics are different.

1. PCI-E X16: It is a high-speed serial computer expansion bus standard, which can meet the needs of low-speed equipment and high-speed equipment in a certain period of time in the future.

2. PCI-E: The products can support PCI Express bus technology, the total bandwidth of the expansion port in X1 mode can reach 1Gb S, and the X16 graphics interface can reach the amazing bandwidth value of 16Gb S.

3. PCI-E: The 128B 130B decoding mechanism has been added, which can ensure almost 100% transmission efficiency, which is 25% higher than the previous version of the 8B 10B mechanism, thus doubling the transmission bandwidth.

Second, the transmission rate is different.

1. PCI-E X16: Adopt the principle of high-speed serial operation, and the interface transmission rate is reached.

2. PCI-E: On the basis of the version, the interface rate has been increased to 5GHz, and the transmission performance has also been doubled.

3. PCI-E: The data transmission rate reaches 8GT S, which greatly improves the bus bandwidth, and the server version of Intel's Sandy Bridge processor family will also natively support PCI-E.

Third, the principle is different.

1. PCI-E X16: Higher maximum system bus throughput, lower IO pin count and smaller physical size, better bus device performance scaling, more detailed error detection and reporting mechanism (Advanced Error Reporting, AER) and native hot-swap function.

2. PCI-E: Adopting point-to-point working mode, each PCI device has its own dedicated transmission line, so that there is no need to apply for bandwidth to the entire bus, which can avoid the problem of multiple devices competing for bandwidth, while in the PCI system of shared structure, multiple devices often compete for bandwidth.

3. PCI-E: data multiplexing indication, atomic operation, dynamic power adjustment mechanism, delay tolerance report, loose transmission ordering, base address register (bar) sizing, IO page fault, etc., so as to improve platform efficiency, software model flexibility, and architecture scalability in an all-round way.

PCI -E It is a serial protocol standard that comes in three versions:.

Main differences: 1. The difference is that the bandwidth that can be borne is different, that is, the running speed is often different. But there are high to low compatibility, compatibility, compatibility between them.

2. X16 is represented as a channel, that is, 16 channels, and more are 1 channel, 4 channels, 8 channels, and 16 channels. The higher the number of channels, the faster and more performant it will be.

PCI Express bus technology is widely used in today's next-generation storage systems. The PCI Express bus provides extremely high bandwidth to meet the needs of the system. The PCI-E specification has also been determined, with encoded data rates doubling the equivalent PCI-E specification, with bidirectional speeds of up to 32Gbps on the x32 ports.

First, in appearance.

1. PCIEX16 is very long, longer than the previous AGP slot.

2. PCIEX1 is very short and can only be inserted into the front end of the gold finger of PCIEX1 graphics card.

2. Functions. 1. PCIEX16 slot is specially designed for graphics cards.

2. PCIEX1 can be used for PCIe sound card and PCIe network card.

3. Provide support.

1. PCI-Express X1, supported by Nanqiao.

2. PCI-Express X16, supported by Northbridge.
