Graphics card professional problems, double A card firefight?

A card firefight is not this concept.

The crossfire of the A-card is the firefight between the discrete graphics card and the onboard graphics card, which is called cross fire

The N-card firefight is a firefight between two independent graphics cards, called SLI

1.No. 2.Not satisfying 1,2 is not true.

The SLI multi-card technology of card CF and N card requires the investment of RMB, and a motherboard is at least 1000 yuan or more, do you think your motherboard has such a high grade?

4.There is no need to exist if it is not satisfied.

There are two situations of A card crossfire, one is high-end firefight, that is, 790FX motherboard, multi-HD 2900, HD 3800, HD4800 series multi-card crossfire. The other is a low-end firefight, which is 780G and 790GX with HD2400 and 2600.

Note: Crossfire must be the same grade product, different grades cannot be crossfired, for example: if you use a 780g motherboard, on the independent 4830, crossfire can not be realized.

This crossfire is not the same for the two graphics cards.

AMD now has a hybrid firefight, but it also supports integrated display + discrete display firefight.

It is recommended not to crossfire, the performance is not greatly improved, and the power consumption is too large.

It is recommended to directly replace the graphics card with a better one.

What kind of fire, only when there is a problem, the fire.

Do you want to pay that too?

Crossfire is the BAI of AMD graphics cards

Patented technology, so all DU nvidia graphics cards, no matter what the model, no matter what the price, are not crossfire version function.

Crossfire is divided into a firefight between a discrete graphics card and a firefight between a discrete graphics card and an integrated graphics card (the integrated graphics card must also be an integrated graphics card from AMD).

Crossfire is a patented technology for AMD graphics cards, so all NVIDIA graphics cards, no matter what.

What is the back model, no matter what the price is, there is no answer to the crossfire function.

Crossfire is divided into firefights between discrete graphics cards and firefights between discrete graphics cards and integrated graphics cards (integrated graphics cards must also be integrated graphics cards from AMD).

Theoretically, AMD's mid-to-high-end discrete graphics cards of more than 1000 yuan all support dual discrete graphics card crossfire technology.

However, the hybrid firefight between the discrete graphics card and the integrated graphics card can only be exchanged between the APU and some discrete graphics cards of mid-range and low-end models, and the mid-range and mid-to-high-end discrete graphics cards do not support the hybrid firefight.

But not all low-end and mid-range models of discrete graphics cards support hybrid crossfire, as far as I know, HD 6570 and HD 6670 and HD 7730 models all support hybrid crossfire, and HD 7750 and HD 6770 support hybrid crossfire, it's not very clear. Starting with the HD 7770, all models above do not support hybrid firefights.

These two can only be a card to be integrated + N card independent, it is best to buy an APU and buy an N card.

Crossfire: Two or more A cards N cards only support SLIs

Check it directly in the graphics driver of the A card.

As shown in the figure below, it is the home page of the A-card driver (new version), and the red arrow points to "Crossfire" as "On", indicating that the CF (Crossfire) is successful

1.A card and N card can now be crossfire through third-party chipsets, currently supported by MSI Big Bang series motherboards, but it is more expensive, and the A+N crossfire efficiency is not high, unlike the A A and N crossfire models of the model.

2.There are two graphics card slots that can indeed be used to build a firefight, because the CF technology of the A card is licensed for free, but for the N card, the motherboard manufacturer must get a license, so the formation of the A card is definitely possible. However, if the second slot is 4x, it is not recommended to form a dual-card crossfire, because the x16+x4 crossfire is much worse than x8+x8, and it cannot give full play to the dual-card performance.

3.Crossfires of different levels of graphics cards will generally have stronger performance than higher graphics cards, but the amplitude is not too large.

4.At present, the firefight of the A card is relatively perfect, and the firefight between the graphics card and the core, such as the Barts core 6870 6850, can be crossfired. However, there is no exchange of fire between the different cores.

And in the same firefight with the core, you must use the one with strong performance as the main card, such as 6870 6850, and 6870 as the main card. If you take 6850 as the main card, it will be unstable.
