What do you mean, double video card fire?

What is the dual-card technology, in fact, this is a special system with two of similar graphics cards. The goal is often to significantly improve the entire computer's image processing capabilities, in the running of 3D games can be better performance.

Advantages: Greatly improve the computer's image processing ability

Disadvantage: Due to price and performance requirements, ordinary users do not need to configure two graphics cards

Applicable to the crowd: high-end players, the game video quality requirements higher users

Dual card technology is good, but before buying, consider whether you really need?

Usually, as long as DIY enthusiasts or game enthusiasts will go to use dual graphics system, after all, the previous support for dual graphics boards will be more expensive, two graphics card configuration will directly improve the computer's installed costs. But for ordinary users, a video card has been basically satisfied with the requirements, with the integration of graphics technology, most ordinary users will not consider using dual graphics cards.

For nearly a year, motherboard manufacturers in order to highlight the "affordable configuration luxury" selling point, to attract more users to buy, introduced a lot of dual graphics card function of the motherboard, in fact, to the motherboard configured with two PCI-E x16 slots, users can insert two PCI-E cards, build dual graphics system.

Double-SIM Shootout

SLI and Crossfire are respectively the dual sim or multiple Card interconnection workgroup mode of Nvidia and ATI two. Its essence is similar. It's just different.

SLI Scan Line interlace (SCAN wire interleaving) technology is 3dfx Company applied to Voodoo technology, it by the 2 block Voodoo card with the SLI line physical connection, the work of a voodoo card is responsible for rendering the screen odd line scan, The other is responsible for rendering even-line scans to achieve a "double" performance of two graphics cards "connected" together. SLI Chinese name Speed Force, the current SLI working mode differs from the earlier voodoo, and now changes to screen partition rendering.

Crossfire, Chinese name Crossfire, is a multi-GPU technology, which allows multiple display cards to be used alongside one computer at the same time, increasing operational efficiency and competing with NVIDIA's SLI technology. Crossfire Technology was officially released on June 1, 2005 in Computex Taipei 2005, a year later than SLI. From the first public date, Crossfire has undergone a revision.

(Note: The dual SIM card, although the theoretical image processing ability increased by one times, the actual performance can only be increased to 40%)

Mixed fire

Hybrid Graphics Hybrid Graphics is also the top technology for AMD on the 7-series integrated chipset, and we now know the key words: mixed fire, energy efficiency, performance, price.

Mixed fire, English name Hybrid CrossFireX is an interpretation of the hybrid graphics hybrid graphics technology, we can plug in the support Hybrid CrossFireX mixed fire of the independent graphics card plug-in support hybrid A hybrid CrossFireX system is built on the CrossFireX's 7-series consolidated motherboard, and when high load operations are required, independent graphics and integrated graphics will work together for optimal display performance, and only integrated graphics can be used when operational requirements are lowered. Coupled with AMD's cool ' n ' quite technology, the entire platform's power consumption will be reduced to the lowest point, which will meet people's demand for rational use of energy.

Hybrid Graphics Hybrid Graphics technology includes Hybrid CrossFireX mixed exchange of fire technology, Sorroundview long display technology, Powerplay power management technology and powerxpress dual graphics switching technology four parts

1.Hybrid CrossFireX mixed Fire Fighting technology.

Simply put, Hybrid CrossFireX mixed exchange of fire technology is the use of onboard graphics and external video cards to exchange fire, thereby enhancing performance, for performance, according to the existing data shows that the maximum performance of mixed Crossfire can be improved to about 50%.

2.SorroundView Multi-head display technology

Not a new technology, which has been seen in the early ATI chipset. Business users are more used than ordinary users. In general, the threshold of four display technology is lowered to create a larger working table or to build a TV wall.

3.PowerPlay Power Management Technology

The energy-saving technology used by AMD's independent graphics card is not unique to hybrid graphics technology. Powerplay Dynamic power management can automatically adjust the frequency according to the graphics load, which can effectively reduce the power consumption of the video card.

4.PowerXpress Dual Graphics Switching technology

From the new AMD notebook platform Puma dual graphics switching technology, powerxpress dual graphics switching technology allows users to not restart the computer can also achieve the independent graphics and integrated video card switching. The use of Powerxpress dual graphics switching technology is to extend the laptop battery time, on the desktop platform is to reduce power consumption. According to the 3D load, when the 2D or 3D light load, integrated graphics work, independent video card into hibernation mode. When the 3D load is overloaded, the independent video card begins to work. Nvidia's counterpart technology is hybrid power hybrid technology. The two technologies work essentially the same, but the latter have been the first to release the formal support of the driver, AMD users need to wait for a while.

How to use mixed fire

Using a mixed firefight is very simple, plug in a separate graphics card, into the catalyst-driven Program Control Panel, open the Exchange of fire options, you can perfect the experience of mixed fire.

Mixed fire and integrated graphics performance test comparison

Through the information provided by AMD and the existing test data, it is shown that the RS780 onboard video card with the low-end video card will have better performance improvement.

Power Control Perfect

With powerxpress dual graphics switching technology, in 2D mode or Light3d mode, computer independent display chip will be screen, only the integrated display core is responsible for the operation, the graphics card will be in a sleep state, so that the power consumption significantly reduced when entering the performance 3D mode, The video card reverts to normal mode without the system reboot. A minimum of 1.2W, and its own maximum function is 20W. In other words, although high-end users can not use the RS780 mixed fire to enhance the display performance, but with high-end graphics, control power consumption, energy saving, is really practical.

AMD released the Catalyst driver package 8.8. Although the new features are not much, it is a great boon for Windows XP users: Not only is there the latest Avivo video technology, but also the hybrid firefight (Hybrid Graphics) is no longer a patent for Windows Vista!

The Catalyst 8.8 Driver package includes the following components:

Radeon Display driver version 8.522 (compiled in 2008.7.31)

Multimedia Center version 9.16 (XP)

HydraVision (XP & Vista)

HydraVision Basic Edition (XP)

Remote wonder 3.04 (XP)

WDM Driver Installation Module

South Bridge/IXP Chip driver

Catalyst Control Center Version 8.8

The catalyst 8.8 is routinely supported from Radeon 9500 to Radeon HD 4800 full range desktop graphics, theater and All-in-wonder multimedia graphics, and integrated chipsets for each integration video card, although the compilation date is earlier and remains at the end of last month, However, formal support for Radeon HD 4870 X2 has been added.
