5700xt Crossfire support
question or statement?
Question can i use 5700 xt crossfire
as far as i know you can use Multi-GPUs in Vulkan and DX12 BUT NOT in DX11 (& earlier) and OpenGL.so YES and NO
As far as I am aware of AMD dropped crossfire support for the RX 5700 series entirely. To the best of my knowledge this was done due to the extremely low percent of users who implemented crossfire.
AMD will not support Crossfire (DX11 and earlier) for the 5700 series.
DX12/Vulkan based multiGPU is supported by the game developer and not the GPU drivers. So if a game has multiGPU support under DX12/Vulkan that will work.
HiI looked for articles about this and looked at the RX 5700/XT Specs. No mention of DX11 Crossfire on the specs.
AMD seems to want to focus on DX12 and Vulkan and neglect the fact that the vast majority of games run on DX11 and below.
This is surprising because it lkooks like Navi DX11 performance is finally catching up to Nvidia somewhat whereas the Nvidia RTX GPUs are now much better at DX12 and Vulkan versus GTX1080/1070/1060 series. I see this article: https://www.pcgamesn.com/amd/rx-5700-xt-killed-crossfire
Well AMD kept that quiet.
The Radeon VII does not support crossfire either mentioned in this article:https://www.techradar.com/uk/reviews/amd-radeon-vii
More reason not to purchase AMD GPUs then.
Nvidia RTX2070 Super supports SLI. https://www.overclock3d.net/news/gpu_displays/nvidia_s_rtx_2070_super_supports_sli/1
I still run dual R9 Fury X in Crossfire DX11 and DX12 MultiGPU rather than ruinning a single RX Vega 64 Liquid as they perform better than the single RX Vega 64 Liquid on the games I run.
AMD did do a good job of improving DX11 Crossfire Support on AAA titles following RX480 launch for sure. It can be made to work well.I have no idea how much effort it took, though, but since dual RX480 in DX11 Crossfire or DX12 MultiGPU was the only thing AMD had to fight the GTX1080 at the time I guess it must have been a priority.
"Nvidia RTX2070 Super supports SLI"
Sure, but you have to pay $80 for the NVLink bridge. The gouging never stops with them.
