Most compatible systems are based on Intel's Sandy Bridge processor architecture, using the Huron River platform.
No working product has yet been developed. Computer bus interfaces provided through the M. It is up to the manufacturer of the M. This device would not be possible had it not been for the ePCIe spec.
OCuLink standing for "optical-copper link", since Cu is the chemical symbol for Copper is an extension for the "cable version of PCI Express", acting as a competitor to version 3 of the Thunderbolt interface.
Since, PCIe has undergone several large and smaller revisions, improving on performance and other features. Transfer rate is expressed in transfers per second instead of bits per second because the number of transfers includes the overhead bits, which do not provide additional throughput;  PCIe 1.
This updated specification includes clarifications and several improvements, but is fully compatible with PCI Express 1. No changes were made to the data rate.
Overall, graphic cards or motherboards designed for v2. Intel 's first PCIe 2. However, the speed is the same as PCI Express 2. The increase in power from the slot breaks backward compatibility between PCI Express 2.
At that time, it was also announced that the final specification for PCI Express 3. Following a six-month technical analysis of the feasibility of scaling the PCI Express interconnect bandwidth, PCI-SIG's analysis found that 8 gigatransfers per second can be manufactured in mainstream silicon process technology, and can be deployed with existing low-cost materials and infrastructure, while maintaining full compatibility with negligible impact to the PCI Express protocol stack.
A desirable balance of 0 and 1 bits in the data stream is achieved by XORing a known binary polynomial as a " scrambler " to the data stream in a feedback topology.
Because the scrambling polynomial is known, the data can be recovered by applying the XOR a second time. Both the scrambling and descrambling steps are carried out in hardware.
Additionally, active and idle power optimizations are to be investigated. Their IP has been licensed to several firms planning to present their chips and products at the end of Broadcom announced on 12th Sept.
It is expected to be standardized in Apple has been the primary driver of Thunderbolt adoption through , though several other vendors  have announced new products and systems featuring Thunderbolt.
Historically, the earliest adopters of a new PCIe specification generally begin designing with the Draft 0. At the Draft 0. The PCIe link is built around dedicated unidirectional couples of serial 1-bit , point-to-point connections known as lanes.
This is in sharp contrast to the earlier PCI connection, which is a bus-based system where all the devices share the same bidirectional, bit or bit parallel bus.
PCI Express is a layered protocol , consisting of a transaction layer , a data link layer , and a physical layer.
The Physical Layer is subdivided into logical and electrical sublayers. The Physical logical-sublayer contains a physical coding sublayer PCS.
The terms are borrowed from the IEEE networking protocol model. At the electrical level, each lane consists of two unidirectional differential pairs operating at 2.
Transmit and receive are separate differential pairs, for a total of four data wires per lane. A connection between any two PCIe devices is known as a link , and is built up from a collection of one or more lanes.
Devices may optionally support wider links composed of 2, 4, 8, 12, 16, or 32 lanes. This allows for very good compatibility in two ways:.
In both cases, PCIe negotiates the highest mutually supported number of lanes. Even though the two would be signal-compatible, it is not usually possible to place a physically larger PCIe card e.
The width of a PCIe connector is 8. The fixed section of the connector is PCIe sends all control messages, including interrupts, over the same links used for data.
The serial protocol can never be blocked, so latency is still comparable to conventional PCI, which has dedicated interrupt lines. Data transmitted on multiple-lane links is interleaved, meaning that each successive byte is sent down successive lanes.
The PCIe specification refers to this interleaving as data striping. While requiring significant hardware complexity to synchronize or deskew the incoming striped data, striping can significantly reduce the latency of the n th byte on a link.
As with other high data rate serial transmission protocols, the clock is embedded in the signal. At the physical level, PCI Express 2.
This coding was used to prevent the receiver from losing track of where the bit edges are. To improve the available bandwidth, PCI Express version 3.
It also reduces electromagnetic interference EMI by preventing repeating data patterns in the transmitted data stream.
On the transmit side, the data link layer generates an incrementing sequence number for each outgoing TLP. It serves as a unique identification tag for each transmitted TLP, and is inserted into the header of the outgoing TLP.
The receiver sends a negative acknowledgement message NAK with the sequence-number of the invalid TLP, requesting re-transmission of all TLPs forward of that sequence-number.
The link receiver increments the sequence-number which tracks the last received good TLP , and forwards the valid TLP to the receiver's transaction layer.
Barring a persistent malfunction of the device or transmission medium, the link-layer presents a reliable connection to the transaction layer, since the transmission protocol ensures delivery of TLPs over an unreliable medium.
In addition to sending and receiving TLPs generated by the transaction layer, the data-link layer also generates and consumes DLLPs, data link layer packets.
In practice, the number of in-flight, unacknowledged TLPs on the link is limited by two factors: PCI Express implements split transactions transactions with request and response separated by time , allowing the link to carry other traffic while the target device gathers data for the response.
PCI Express uses credit-based flow control. In this scheme, a device advertises an initial amount of credit for each received buffer in its transaction layer.
The device at the opposite end of the link, when sending transactions to this device, counts the number of credits each TLP consumes from its account.
However, bigger slots can actually have fewer lanes than the diagram shown in Figure 5. For example, many motherboards have x16 slots that are connected to x8, x4, or even x1 lanes.
With bigger slots it is important to know if their physical sizes really correspond to their speeds. Moreover, some slots may downgrade their speeds when their lanes are shared.
The most common scenario is on motherboards with two or more x16 slots. With several motherboards, there are only 16 lanes connecting the first two x16 slots to the PCI Express controller.
This means that when you install a single video card, it will have the x16 bandwidth available, but when two video cards are installed, each video card will have x8 bandwidth each.
But a practical tip is to look inside the slot to see how many contacts it has. I looked at a couple of other similar questions but they didn't address these specific topics.

Some slots use open-ended sockets to permit physically longer cards and negotiate the best available electrical and logical connection. PCIe version v1, v2 or v3.

For example, if a slot with an x1 connection is required, the motherboard manufacturer can use a smaller slot, saving space on the motherboard.
