The new graphics processing cards from AMD Do not support creating multiple arrays that were very popular in the past
The dual launch of new Ryzen processors and Navi video cards at the same time flooded a lot of fresh and interesting information on the network, some of which fell through the chairs and not necessarily received enough attention - such as the fact that theRadeon RX 5700 andRadeon RX 5700 XT does not include multi-processor support for CrossFireX processing cards.
In the past, creating arrays with two video cards and even more has been a common option for avid gaming enthusiasts for increased performance from an existing and affordable system - and this has been done through SLI technology and a dedicated external bridge in the NVIDIA And CrossFireX (or CrossFire) technology and its own dedicated external bridge on the Radeon AMD.
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 Video And each is responsible for the processing of a single frame alternately (under the more common AFR mode).
Now, with the official launch of the Navi models, we find that in addition to not including a dedicated material connection for CrossFireX systems, they also do not offer software support - meaning consumers will not be able to connect a pair of RX 5700 or RX 5700 XT cards for increased performance in titles Supporters based on the standardsDirectX 9, DirectX 11 or OpenGL. What is supported in the red cards of the New Age is the modern ability in standards DirectX 12 andVolcano To use several different media internally (via thePCI-Express And the motherboard itself - Explicit Multi-GPU) and dynamic, which takes into account the processing power and typical latency when dividing the processing work on each frame and frame.
In other words, most of the titles of the past will not operate in any form in a double-deck format,ships Current, while out of the modern titles there is a very limited list that can be counted on less than two hands of multi-core processing technology that is supported - is that a final nail in the CrossFireX closet? Can't triple comeback in more advanced video cards of the eraships, Although for now it certainly looks like the end of the road.
Lack of support of AMD May be more surprising than usual given the fact that the new GeForce RTX 2070 Super model actually supports arrays SLI 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 the original GeForce RTX 2080 which also supported the technology. Still, when it seems that the number of modern graphics processing cards that support ultra-low capacity and stands for some very expensive and expensive models - it's hard to argue with the assertion that CrossFireX and SLI 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.
