Performance of SLI and CrossFire systems is heavily dependent on what is being rendered and on the video drivers. There are real-world issues related to parsing a scene out to the two cards, and some 3D engines are not very accomodating to the multi-card approach. However, in practice this is never achieved. The theoretical upper limit for performance of an SLI/CrossFire system with 2 GPUs is twice that of a single-card system (assuming two identical cards are used an issue we will touch on later). So do they provide twice (or three or four times) the performance of a single card? So computers with 2, 3, or 4 GPUs may be built using either technology. Because CrossFire allows different cards to be used, 3-GPU CrossFire systems (called CrossFireX, without the Quad) can be built by combining one card with 2 GPUs and another with 1 GPU. Additionally, NVIDIA has now made it possible to use 3 cards together (which it calls 3-way SLI). However, both companies have now produced cards with 2 GPUs on a single card (model numbers ending in X2), opening the door to what are called Quad-SLI or CrossFireX Quad configurations. Originally the limit was two cards, and therefore two Graphics Processing Units (GPUs).
This is intended to be as transparent to the rest of the computer as possible. SLI and CrossFire provide a system for two or more video cards to work together to render the same video stream.

Overall it appears that Strange Brigade and Sniper Elite 4 are well optimized for mGPU settings: AMD Radeon RX 6800 XT multi-GPU Test At 1440p Deus Ex the performance even drops to 95% when mGPU is enabled.

Depending on the game settings we are looking at a 101% to 156% performance scaling at 1080p resolution when two RX 6800 XT cards are used.

The mGPU support must be enabled through the Radeon Software and it will be visible in TechPowerUP GPU-Z software:ĪMD Radeon RX 6800 XT Multi-GPU in GPU-Z, Source: TweakTownĪs expected, the mGPU support makes more sense as the resolution increases (4K is heavily GPU bound). Those games are heavily based on AMD technologies, so the support for multi-GPU is obviously there. TweakTown tested two Radeon RX 6800 XT graphics cards (one reference and one custom from XFX) in four games and at three resolutions. Two RX 6800XTs would cost 1300 USD, although this card is nowhere to be found in stock and if they are, they are certainly not sold at this price. On the other hand, we have just released Radeon RX 6800 series, which are much cheaper than the flagship Ampere card. This graphics card is so expensive (1,499 USD), that barely anyone had the chance to test it. The current generation of NVIDIA RTX 30 graphics cards only has one model with NVLink fingers, the RTX 3090.

Soon after that both NVIDIA and AMD have begun killing its multi-GPU technologies, which only generated driver issues and development costs for manufacturers. This technology required support from the game developers and 5 years later no one is using it. Back in 2015, the news broke that DirectX 12 will allow multi-GPU Explicit Multi-Adapter support, a technology that would allow the mixing of the graphics card from different vendors to work in tandem. The Crossfire and SLI technologies might be dead, but the multi-GPU support certainly has not been abandoned. TweakTown covered a topic of the multi-GPU configuration of the AMD’s fastest (at least for one more day) Radeon RX graphics card.
