英特爾10nm冰湖處理器緩存系統改進,IPC性能提升15%?
14nm產能不足對英特爾來説是一次考驗,但真正麻煩的還是10nm工藝延期,日前有爆料稱英特爾取消了10nm工藝,嚇得英特爾官方馬上闢謠,表示10nm工藝進展良好,與預期時間時間相符。10nm取消是不可能取消的,英特爾的10nm處理器都已經發展出Cannonlake大炮湖及Ice Lake冰湖兩代了,真正大規模上市的是冰湖處理器。此前我們知道冰湖處理器的核顯會有大幅提升,現在2核4線程的U系列冰湖處理器性能也曝光了,L1、L2緩存容量增大,2.6GHz下GK4單核性能也有4100多分,與同規格現有處理器相比的話,IPC性能大概提升了15%。
關於英特爾的冰湖處理器,之前在Sisoftware的數據庫中曝光過多次了,現在Geekbench 4中也出現了一款2核線程的冰湖-U系列處理器,基礎頻率2.6GHz,支持DDR4內存。
在這個測試中單核性能為4151分,多核性能7945分,這是個什麼概念呢? Reddit 爆料的貼子上有人對比了同樣2.6GHz頻率、2C/4T的M3-Y70處理器
與kaby Lake架構的Y70相比,冰湖處理器的L1指令緩存還是32KB,不過數據緩存從32KB增加到了48KB,L2緩存則從256KB翻倍到了512KB,L3緩存是4MB,因此從緩存系統上來説,冰湖處理器的L1數據緩存增加了50%、L2緩存增加了100%。
性能方面,Kaby Lake在2.6GHz頻率下單核3631分,多核6870分,算起來單核性能提升14.3%,多核提升15.6%,平均下來IPC性能大概提升15%。
IPC性能一下子提升15%,這似乎是很了不得的提升了,畢竟過去幾年中英特爾處理器的IPC性能提升幅度一直有限,但考慮到Kaby Lake到Ice Lake處理器經過了好幾代了,而且有14nm到10nm工藝的升級。
考慮到緩存及架構上的改進,10nm冰湖處理器的IPC性能大幅提升倒是可信的,只不過基於現在的成績還缺少實錘證據,上面的兩個處理器TDP功耗並不是一個級別的,冰湖處理器的加速頻率也沒確定。另外低頻率下Cannonlake架構的酷睿i3-8121U處理器的單核也有4100多分,多核7900多分,雖然後者的頻率是2.2-3.0GHz範圍。
