The new RDNA 3 cards may lack power on their own but can it still do crossfire?

AMD’s enthusiast-class graphics card, the Radeon RX 7900 XT, was introduced on November 3, 2022. With a release date in mid-December, can the new RDNA 3 cards crossfire?
The card supports DirectX 12 Ultimate and is constructed using a 5 nm process based on the Navi 31 graphics processor in its Navi 31 XT form.
With a die area of 306 mm² and 58,000 million transistors, the Navi 31 graphics processor is a sizable chip. As a result, Radeon RX 7900 XT will be able to run all current video games.
The DirectX 12 Ultimate capability also ensures that subsequent video games will include hardware raytracing, variable-rate shading, and other features.
To meet the Radeon RX 7900 XT’s target shader count, AMD blocked some shading units, in contrast to the fully unlocked Radeon RX 7900 XTX, which uses the identical GPU but has all 6,144 shaders activated. 192 ROPs, 336 texture mapping units, and 5376 shading units are included.
Using a 320-bit memory interface, AMD has paired the Radeon RX 7900 XT with 20 GB of GDDR6 memory. Memory runs at a speed of 2500 MHz, while the GPU operates at a frequency of 1500 MHz with a boost to 2400 MHz (20 Gbps effective). Furthermore, the card includes 84 acceleration cores for raytracing.
The best platform for multi-GPU gaming performance is AMD CrossFireTM technology. AMD CrossFireTM, which unleashes game-dominating power, utilizes the power of two or more graphics cards operating in parallel to enhance gaming performance significantly.
In order to use CrossFire technology, a computer must have multiple PCI Express slots. This motherboard supports it and, depending on the model, either two ATI Radeon graphics cards or one card and a matching CrossFire Edition card.
The most recent AMD RX 7900 XT does support crossfire. Since the feature was dropped in 2017, it wasn’t as popular as expected. Instead, AMD moves towards a multiple GPU product as in their server lineup.
