Sur un chipset x570 UD peut-on couplet un GPU de type RX5700XT avec un GPU de type HD 7950 VAPOR X ?

J'ai une carte mère de type X570 UD de GYGABYTE, un processeur de type 3900x et une carte graphique de type RX 5700XT NITRO +.

J'ai mon ancienne carte graphique de type HD7950 VAPOR X, et je voulais savoir si je peux la couplet avec mon nouveau GPU pour gagner davantage en performance

According to this Tech site, AMD says that the RX5700XT doesn't support Crossfire: https://www.overclock3d.net/news/gpu_displays/amd_confirms_that_their_radeon_navi_rx_5700_series_gra... 

To answer this, AMD has released the following statement; 
 
    RX 5700 Series GPU's support CrossFire in 'Explicit' multi-GPU mode when running a DX12 or Vulkan game that supports multiple GPU's. The older 'implicit' mode used by legacy DX9/11/OpenGL titles is not supported.

  
So what does this mean? For starters, this means that CrossFire is not supported on the Navi RX 5700 series. PC gamers should not expect to run Navi in a multi-GPU configuration, at least outside of the rare usage of "explicit" multi-GPU in the occasional DirectX 12 or Vulkan title. This level of multi-GPU support remains rare in modern gaming titles, which means that in most cases multi-GPU support isn't possible with Navi.
