Since the introduction of its Pascal architecture, NVIDIA scaled down its SLI support and it appears AMD is now going the the same route. While AMD heavily played the CrossFire card when it launched its Polaris cards, Gamers Nexus noticed AMD did not even mention CrossFire once during the Vega launch event.
AMD told the media that the industry is largely moving away from multi-GPU configurations. The Radeon RX Vega 64 and RX Vega 56 video cards will support CrossFire but the feature will not be promoted. While not said with as many words, this also implies the company will dedicate less resources to CrossFire support and optimizations in future drivers.
RX Vega 64 and RX Vega 56 will support CrossFire, technically speaking, but AMD noted that the industry is largely moving away from multi-GPU configurations. We agree with that sentiment, and have for a while, though that’s been the case since before Polaris and its heavy CF marketing language. Regardless, AMD has minimized its marketing focus on multi-GPU for RX Vega and, although the cards can technically function in multi-card arrays, AMD noted that the value is rough when considering limited developer support.
