What does dual graphics card crossfire mean? How much is crossfire performance worth when computer is configured with two graphics cards?
When we buy motherboards, we may find that some motherboards have two PCI-E slots, that is, two independent graphics cards can be inserted at same time to form a dual graphics crossfire solution, and some motherboards can even support more independent graphics cards. So what does dual graphics card crossfire mean? How much is crossfire performance worth when computer is configured with two graphics cards? With doubts, I popularize science for everyone, so that everyone can better understand knowledge of two crossfire video cards.
Not every computer can set up dual graphics card crossfire, and setting up dual graphics card crossfire requires following conditions:
Conditions for setting up a computer with two graphics cards for CrossFire:
1. Two or more independent graphics cards that can cross work (NVIDIA graphics cards can only cross work with NVIDIA graphics cards and must be same model. AMD graphics cards can only work with AMD graphics cards and require same architecture). video card. In addition, some APU graphics cores can also work with AMD with same architecture.)
2. The motherboard chipset must support CrossFire, and motherboard must support SLI and CrossFire
3. Need crossfire wire or crossfire connector
4. The motherboard has at least two PCI-E 16X slots
What does a shootout between two graphics cards mean?
Dual graphics card crossfire technology actually allows two or more independent graphics cards to be used at same time to increase processing power of GPU. Simply put, in a computer, using two video cards at same time will undoubtedly improve graphics performance compared to a single video card.
At present, independent video cards are mainly divided into two camps: NVIDIA and AMD. Whether you choose NVIDIA or AMD, they have their own crossfire technology for graphics cards. NVIDIA graphics cards use SLI crossfire technology, while AMD graphics cards use CrossFire technology.
How much better is performance of a computer with two graphics cards?
Dual graphics does improve graphics performance, but it's not a double improvement. Typically, dual graphics cards can theoretically improve performance by about 1.5x. That is, we spent price of two video cards, but we can only enjoy performance of a one-and-a-half video card, this is clearly a little uneconomical. In addition, with a significant increase in power consumption of CrossFire video card, we need additional support for power supply.
Regular computer users don't need to set up dual card crossfire technology at all, it's better to directly purchase a higher performance single card, because it's a bit disadvantageous in terms of performance improvement. However, dual graphics cards are not completely useless. For professional workstations in complex scenarios, dual graphics cards can better meet needs of professional scenarios.
