根據 PCI-SIG 聯盟的消息,最終規範應該會在2021年制定完畢
因此預計可能會在2022年到2023年之間的時間會有採用 PCI-E 6.0 規範的產品。
與 PCI-E 5.0 相比,PCI-E 6.0 的速率將再次翻倍,訊號速率再次提升達到64GT/s
每通道的頻寬接近8GB/s(具體為7880MB/s)。PCI-E 6.0 x16 插槽的頻寬將接近128GB/s
(單向頻寬)
PCI-SIG 聯盟始終以僅發布可以使上一代數據速率翻倍的規範版本為目標。
PCI-E 6.0 還將向下相容所有以前的規範,這也是該聯盟的另一個主要目標
該小組實施了一些主要變更,包括 PAM-4(具有四個等級的脈衝振幅調變)編碼
以及具備包括低延遲 FEC(Forward Error Correction,前向誤差更正)
與其他提高頻寬效率的機制,以用於向下相容。
