關於 AMD AM5 Ryzen 7000 APU，網路上開始流傳因為 APU 內的 PCI-E 通道有被削減 / 禁用，將導致無法有效利用主機板上的一些插槽。目前的 AM5 CPU 設有 16 + 4 + 4 共 24 組 PCI-E (5.0) 通道供板廠引出至各插槽，前題是板廠有把它們拉出來。如果 AM5 APU 將只有 16 + 4 = 20 甚至只剩 16 組 PCI-E 通道，這或許會影響目前的 AM5 主機板，因為有些 AM5 主機板已把 16 + 4 + 4 悉數拉出來供使用者隨意使用，有些則只有 16 + 4，甚至只有 16。筆者簡單整理五大台系板廠的 AM5 A620 / B650 / B650E 主機板關於 CPU 的 PCI-E 通道分配設計資訊，如有錯誤或遺漏之處則以板廠官方資訊為準。
AMD AM5 變化多端
假設 X16 為標準配備，AM5 CPU 內剩下的兩組 X4 在不同的主機板上有不同的呈現。M.2 插槽是常見的做法，PCI-E 插槽的做法也不是沒有，不拉的大有板在；至於那是 PCI-E 5.0、4.0 或 3.0，還有那是 X4、X2 甚至 X1，其實板廠在官網上都有提供相關資訊。

因為主機板的線路早已被拉好，其實放什麼 CPU 進去也沒什麼影響。至於為什麼有價值的東西也不好好回收使用而倒掉，筆者認為儘管所有主機板皆合符法規能夠啟用 CPU，還是爺爺說的對，插槽要不要錢、GEN5 要不要錢、X4 的 MLCC 要不要錢、PCB 低損耗板材要不要錢、6 層板要不要錢。網路上有人說這是 AMD 又再搞板廠，沒跟板廠說 APU 將不會有 24 組 PCI-E 通道這麼多，筆者認為這種說法很好笑也很無知，手法純熟又熟悉。這年頭，有能者割之。
