Intel去年在TGL處理器上推出的Thunderbolt4很好,但唯一的主要局限在Intel平台上
AMD這邊還沒有廠商導入,不過大家還有別的選擇,那就是USB4。
自從Intel宣布Thunderbolt3技術與USB4融合之後,未來的USB4各方面其實都很像
Thunderbolt3及現在的Thunderbolt4孔
速率40Gbps,也支援100W快充。Thunderbolt4依然在各種高規格上領先,但USB4會更便宜
而且要全面普及,這是它最大的優勢,而且也會物理相容Thunderbolt3/4,也向下相容
USB3/2/1等協議。
USB4目前的問題主要是沒有平台支援,現在唯一確認能支援USB4的是蘋果的M1晶片及對應
的MacBook筆記型
但後者也是Thunderbolt4為主。USB4普及還得看AMD及Intel的
理論上支援Thunderbolt4就能支援USB4,所以Intel的TGL及本月初發布的RKL處理器應該
都可以
現在是下游廠商缺少USB4方案。
最新消息稱鈺創公司的USB4 E-Maker晶片已經通過了供應鏈的認證,今年會進入大量供貨
階段
最快上半年就會有搭載這一解決方案的AMD或者Intel處理器筆記型問世。
