這段話應該來自AMD推銷自己的GCN架構顯卡的文章,不像是在介紹DX12的標準功能
從DX12 的FL 11_0 到 FL 12_1的說明,我都沒看到ACE是被列為基本功能的說明

至於Maxwell 2.0 是否支援ACE
Wccftech有一篇很長的評論,它有列舉
Nvidia Maxwell 1.0 – 1 Graphics Queue, Mixed Mode not Supported (32 Pure Compute)
Nvidia Maxwell 2.0 – 1 Graphics Queue + 31 Compute Queues

Now contrary to popular belief, Nvidia’s Maxwell 2.0 does support “Asynchronous Shaders”. Do bear in mind that documentation on these things is very limited – most of it comes from engineer comments and documentation on HyperQ (Nvidia’s multiple queue implementation).

他們認為Maxwell 2....
