Crossfire is Dead With Navi, But Multiple GPUs Still Offers Serious Performance Gains

Remember the days when if you had multiple video cards you could run them simultaneously? You know, pump out a few more frames, or allow one to handle physics processing while the other did everything else. Those days may be back, especially as AMD pushes better GPUs but has effectively ended CrossFire.

CrossFire, AMD’s answer to NVIDIA’s SLI for multi-GPU setups, was made for gamers to purchase identical graphics cards and string them together. This improved performance and, theoretically, enabled buyers to buy one card and upgrade with a second in the future. These days we don’t see too many rigs with multiple GPUs. It’s clunky and makes any computer an immediate power hog. A liquid-cooled, GPU like Asetek’s hybrid cooled solutions found under the EVGA banner, will Increase your thermal headroom to enable higher overclock frequencies and lower overall noise output. Or convert your existing Asetek AIO liquid cooler into a cooling solution for GPU with NZXT’s Kraken G12 bracket.

We’re surprised that AMD, with games that support the functionality, has significant improvement with the current NAVI GPUs. Tom’s Hardware found that Uniko’s Hardware tested just that: an RX 5700 and RX 5600 XT. The newer 5600 XT is built for 1080p gaming while the 5700 is intended for higher resolutions, yet in the two games tested performance gains averaged over 50%.

It’s unclear what this means for us in the future. The power issue still exists: both cards running in tandem nearly doubled power output. The cost of those two cards isn’t worth it either as noted by Tom’s: an NVIDIA GTX 2070 Super offers identical performance at half the power output.

What makes it really interesting is how gamers with multiple GPUs will try, considering the news. Do you have multiple cards that you can run? We’d love to hear how it improves the performance of your gaming.
