CrossFireとSLIの違い(表付き)

In the event that you’ve at any point needed or even pondered utilizing numerous illustrations cards inside one framework, then, at that point, the odds are you’ve run over the terms AMD CrossFire and Nvidia SLI. So, these are two advancements that permit the utilization of 2-4 illustrations cards to be utilized at the same time for better (gaming) execution.

CrossFire vs SLI

The difference between CrossFire and SLI is that CrossFire can function with APUs. This implies you can CrossFire your devoted designs card with your coordinated GPU. SLI doesn’t uphold this.

CrossFire is AMD’s restrictive equipment innovation that permits at least two viable AMD GPUs to cooperate, hence further developing illustrations quality and execution. 

Put in the most essential of terms, SLI is Nvidia’s likeness CrossFire, then again, actually it is select to Nvidia GPUs. In its present structure, SLI has been around since 2004, albeit the basic equipment and innovation have transformed impressively over the long run.

Comparison Table Between CrossFire and SLI

パラメーター 比較のCrossFireSLI
Compatible Graphics CardsA great deal of designs cards can be blended and coordinated as long as they are structurally something very similar. Just precisely the card of the same design can be connected.
MotherboardsAny motherboard with enough PCI-e spaces is compatible.Just SLI guaranteed boards are compatible.
追加機能Doesn’t require an extension, Works with APUs. Doesn’t work with incorporated GPUs, Needs SLI Bridge.
パフォーマンスCrossFire offers flexibility and level of alternatives bringing about a less predictable client experience. SLI is tied in with ring-fencing the client experience by restricting similarity to guarantee consistency.
機能しているCrossFire accomplishes an equipment motor tech considered XDMA that opens up an immediate channel between the GPUs. SLI permits each GPU to speak with the other while staying away from the processor through and through just as other superfluous pieces of the GPU.

What is CrossFire?

CrossFire is a multi-GPU innovation that consolidates the handling force of illustrations cards to further develop execution by accelerating the delivery of 3D designs. The exhibition acquires utilizing AMD Crossfire are subject to the application and can convey expanded execution than a solitary GPU setup. 

Vulkan 3D Applications and With DirectX 12, multi-GPU support is only taken care of by the application and ought to be accessible as an alternative in the game launcher or inside the illustrations/video settings menu. The 3D application should uphold MGPU innovation all together for AMD CrossFire to work. Under DirectX, an AMD CrossFire driver profile is required. The AMD CrossFire driver profile gives extraordinary guidelines and advancements to empower ideal execution and similarity with the 3D application. 

At the point when AMD CrossFire support is empowered, one GPU goes about as the essential GPU though the extra GPUs go about as optional GPUs. Designs delivering assignments are split between each GPU to drive a solitary presentation associated with the essential GPU. On the off chance that a subsequent presentation is associated with the essential GPU, the current work area can be stretched out to it, permitting AMD CrossFire to help different showcases. Showcases associated with auxiliary GPUs are naturally impaired. AMD CrossFire support should initially be handicapped to empower these presentations.

What Is SLI?

SLI Bridge interfaces the designs cards. It’s otherwise called the SLI Connector as its motivation is to build up an immediate association between the cards. It’s important that it’s feasible to run two low-end or mid-range cards without the scaffold by utilizing the chipset on the motherboard. 

This is additionally workable for the top-of-the-line cards, albeit not suggested, as the outcomes will be extremely poor thinking about how the chipset simply needs more memory. This is the place where SLI Bridge comes from because it decreases the transfer speed requirements and can send information straightforwardly between the cards. 

While the two-GPU arrangement may be the most well-known one, SLI can likewise be designed in a three or four GPU dynamic by either a solitary scaffold that associates each card or by joining two-way connects. Consolidating three or four double cards set up with a 2-way connect is outlandish as the innovation for the Hexa-or octa SLI arrangement doesn’t exist. 

What’s to come is questionable for these designs as Nvidia is eliminating the help for more than two-card blends because of high driver intricacy. Actually, cards like GTX 1070, GTX 1080, and higher just help the two-way SLI. 

SLI is upheld by all Windows forms following Windows Vista, both 32-bit and 64-bit. It tends to be arranged to deal with Linux, however as there aren’t some very good quality illustrations computer games made for that stage, it appears to be pointless to try and attempt.

Main Differences Between CrossFire and SLI

  1. A lot of plans cards can be mixed and composed with crossfire as long as they are fundamentally something basically the same. Just unequivocally the card of a similar plan can be associated with SLI. 
  2. Any motherboard with enough PCI-e spaces is viable with crossfire. Just SLI ensured sheets are viable with SLI. 
  3. Crossfire doesn’t need an expansion, works with APUs. SLI doesn’t work with consolidated GPUs, Needs SLI Bridge.  
  4. CrossFire achieves a gear engine tech considered XDMA that opens up a quick channel between the GPUs. SLI allows each GPU to talk with the other while avoiding the processor completely similarly as other unnecessary bits of the GPU.
  5. CrossFire offers adaptability and level of choices achieving a less unsurprising customer experience. SLI is connected to ring-fencing the customer experience by limiting similitude to ensure consistency. 

結論

Understanding the major contrasts between AMD CrossFire and Nvidia SLI is valuable, the fame of various GPU arrangements is obviously in decay. All things considered, it’s become to some degree a specialty interest inside the gaming equipment space. 

Amazing single GPUs can fulfill the needs of most games – if not all – with a considerable amount of space for error, implying that the advantage of double GPUs is unimportant. 

The expense of these incredible current GPUs additionally implies purchasing numerous duplicates is restrictive. All in all, there could be at this point not a requirement for multi-GPU arrangements separated from bad-to-the-bone lovers anxious to run very high goals. 

AMD passing the similarity mallet for DirectX 12 games to designers may likewise be a further adhere to the spokes of various GPU omnipresence. On Nvidia’s side, the coordination of SLI in GPUs is reducing with each new series and held for the most expensive models like the 2080 cards.
