The end of an era? Radeon RX 5700 cards do not support CrossFireX technology

The new graphics processing cards from Do not support creating multiple arrays that were very popular in the past

The dual launch of new Ryzen processors and Navi graphics cards simultaneously flooded a lot of fresh and interesting information on the net, some of which fell between the chairs and did not necessarily receive enough attention - for example, RX 5700 and RX 5700 XT does not include multi-processor support for CrossFireX processing cards.

In the past years, creating arrays with two or more video cards was a common option for avid gamers to get increased performance from an existing system at an affordable price - and this was done using SLI technology and a dedicated outdoor bridge modeled on And CrossFireX (or CrossFire) technology and its own dedicated external bridge on the Radeon .

The development of processing technologies, as well as increased awareness of the problems of micro-stuttering in gaming, have resulted in a gradual reduction in the use of these solutions, with the creators and developers of the titles also ceasing to support this capability, in which two processing units are connected to the port And each is responsible for the processing of a single frame alternately (under the more common AFR mode).

The Do not include a connection to an external CrossFireX bridge - nor could you perform an internal interface between the cards based on part of the PCI Express

Now that the Navi models are officially launched, we find that, in addition to not having a dedicated cross-platform connection for CrossFireX arrays, they also do not offer software support in technology - meaning consumers will not be able to connect a pair of RX 5700 or RX 5700 XT cards for increased font performance Supporters based on HP standards 9, 11 or OpenGL. What is supported in the red cards of the New Age is the modern ability in standards 12 and To use several different media internally (via the And the interfaces of the motherboard itself - Explicit Multi-GPU), which takes into account the processing power and typical latency when the processing is divided into each frame.

Remains the last to officially support multi-card arrays for the titles of the past - and it does so within only a few products

In other words, most of the titles of the past will not operate in any form in a double-deck format, While there is a very limited list from the modern titles, which can be found on less than two hands of games that support multi-core processing technology, which is supported - is this the last nail in the CrossFireX cabinet? Three can not be completely comeback on more advanced video cards of the Era-, Although for now it certainly looks like the end of the road.

The future is a smart and optimal use of all the graphics processing resources available in the system with the help of an effective copy engine that will divide the work - but the field is still in its infancy at this stage

Lack of support of May be more surprising than usual given the fact that the new GeForce RTX 2070 Super model actually supports arrays Of a pair of cards of the same type, based on an external jumper - mainly because it is based on a silicon core very similar to that of the original GeForce RTX 2080 which also supported the technology. Still, when it seems that the number of modern graphics cards that support the ability is particularly low and stands on a few expensive models - it is difficult to argue with the determination that CrossFireX and Are technologies that are safe to the history books, and it remains to be hoped that more effective and smart heirs will take their place in time and allow us to use a variety of different and varied graphic processing tools to get a whole larger than the sum of its parts.

  1. CF and SLI were buried a decade ago deep in the ground.

    Expensive, excessive power consumption, outdated drivers.

  2. If AMD goes with the same NV approach (and they certainly do that for the price) then it implies that stronger cards from NAVI's 5 series will support CF.
