Since the PC was invented in 1981, there have been expansion slots on the motherboard to expand computer functions. The most common expansion slot now is the PCI and PCIe slot. The PCI & PCIe bus is a very important component of the X86 hardware computing system. So how should you choose the right PCI or PCIE industrial computer for your computing project?

 

PCI PCIE Industrial Motherboard Computer

 

What is PCI?

PCI (Peripheral Component Interconnect) is a hardware interface standard introduced in the early 1990s, designed to replace older standards in (Industry Standard Computers like ISA and VESA. It allows multiple hardware devices, such as network cards, sound cards, and graphics cards, to communicate with the computer’s central processor. However, PCI has several limitations, including a maximum data transfer rate of 533 MB/s and a shared bus architecture that can create bottlenecks.

 

What is PCIe?

PCIe (Peripheral Component Interconnect Express) is a more modern and advanced interface that succeeded PCI in the early 2000s. It uses a point-to-point serial connection, eliminating the shared bandwidth issue of PCI. Each PCIe lane can achieve speeds of up to 250 MB/s, and multiple lanes (e.g., PCIE x1, x4, x8, x16) can be combined to increase overall bandwidth. For example, PCIe 4.0 offers up to 1969 MB/s per lane, making it ideal for high-performance components like graphics cards and SSDs. Mini PCIe motherboard provides both the standard PCI Express, allowing flexibility in peripheral design. 

 

Differences Between PCI and PCIe

At present, the mainstream display technology in the market is TFT LCD display technology. As a new generation of display technology, I2C OLED display needs to be further improved in terms of process yield, large size, high PPI, service life, and production cost. It has significant advantages in terms of field, wide viewing angle, bendable, thinner and lighter, and transparent. Today, OLED screens have become very popular in small-screen smartphones and are spreading to large-screen fields.

The difference between OLED and LED:

1. Resolution: how many pixels in one Inch, LCD screen module leads.

2. Aperture ratio: It is the light-emitting area divided by the entire screen area. Before segment LCD display, it was leading, but now it is basically OLED.

3. Contrast ratio: the ratio of pure black to pure white, OLED can reach 10000, dot matrix LCD display is 2000, OLED has an absolute advantage in contrast.

4. Color gamut breadth: OLED has beautiful colors and wide color gamut. NTSC can reach up to 100%, while LED screen can reach NTSC 72%. From the perspective of color, OLED screen is more eye-catching.

5. Screen thickness: Due to the simpler structure of the 0.96 OLED screen, it has a thinner and better curvature. Therefore, compared to LED screens, OLED screens can be made thinner.

6. Service life: OLED screens are prone to screen burn-in after being used for a long time, while LED screens do not have screen burn-in, and LEDs have more advantages in service life.

7. Energy saving and power saving: In terms of power saving, OLED emphasizes self-luminescence so it saves electricity, especially if it does not emit light under the screen, it will definitely save electricity. However, the luminous efficiency of OLED is too low, especially under blue light, it consumes more power. Compared with seven segment LED display, it is not the main process to save power. This is not good for the time being, but the OLED screen has the potential to save more power.

8. Price cost: At present, LED screens are definitely cheaper. If only some flagship phones use OLED screens, you will know that its price is definitely more expensive than LED. In addition, if you have changed the screen of the mobile phone, you may also notice that the screen replacement of the OLED screen mobile phone is much more expensive than that of the LED screen mobile phone.

1. Larger scale and scope

Compared with the basic equipment required by traditional LANs, passive optical LANs relatively reduce the number of cables and devices in network deployment. In the traditional LAN architecture, copper cables such as Cat6 are mainly used for data transmission, while the passive optical LAN uses single-mode optical fibers that are smaller, lighter, and less susceptible to interfaces as the main transmission medium. The network distance covered by the LAN is far greater than that of the traditional LAN. For the network deployment with long-distance transmission requirements, the passive optical LAN is undoubtedly a better choice. For example, the hotel industry uses the passive optical LAN architecture to make the network coverage to more rooms.

 

2. Higher efficiency and safety

Different from the traditional distributed LAN, the design of the passive optical LAN is more intelligent and can be managed centrally. All services can be delivered through a single basic device. On-site management of multiple devices, on the contrary, less human intervention can effectively reduce the possibility of human error, with higher efficiency and safety.

 

3. Energy saving and environmental protection

Due to the 'passive' nature, passive optical LAN does not require a power source and generates less heat than copper LAN, thereby reducing the need for traditional distribution frames and telecommunications rooms. The transition from the point-to-point architecture of traditional copper LAN to the point-to-multipoint architecture of passive optical LAN can reduce the energy waste generated by copper cables, aggregation switches or access switches. In addition, once the network deployment is completed, the passive optical LAN can cope with the technical progress in the next few years, and the Cat5, Cat6 or Cat7 copper cable network cables in the passive optical LAN architecture do not need to be replaced due to network upgrades. Frequent changes save more resources and costs.

 

4. Reduce installation and operating costs

Many people have a common misunderstanding about the cost of using traditional copper LAN and passive optical LAN. They think that the price of optical fiber cables is higher than that of copper cable network cables, so the cost of passive optical LAN wiring must be higher than that of traditional copper cable LANs. However, the facts In general, taking into account all the wire and equipment costs in the LAN wiring, and the later operation and maintenance costs, the cost of using a passive optical LAN will not be higher than that of a traditional copper LAN.
