RX6800XT 行mGpu

好似好過癮喎。實際上用，mgpu多數會遇到咩問題?
行非打機軟件，例如執相執片會有幫助嗎?
Thanks

無論係A嘅mGPU同n嘅Sli都有同一問題就係遊戲要支持。遊戲唔支持嘅話fps不升反降。DX12/Vulkan嘅遊戲理論上對多GPU應該比較friendly。

AMD嘅ROCm OpenCL framework係支持mGPU嘅不過ROCm只係可以係Linux到行。同時CPU同主板最好支持PCIe Atomics。

ROCm is built for scale, it supports multi-GPU computing and has a rich system run time with the critical features that large-scale application, compiler and language-run-time development requires.
