雖然3月份GTC大會上發佈新一代安培GPU的可能性基本沒了,但是大家對安培顯卡
尤其是遊戲卡的興趣依然不減。最新爆料稱RTX 3080 Ti的顯存容量12GB,GDDR6速率高達
18Gbps。
從目前12nm圖靈顯卡的情況來看,NVIDIA會在資料中心顯卡上使用GA100大核心
遊戲卡最頂級的是GA102大核心,至少會有RTX Titan 2(暫定名)及RTX 3080 Ti這兩款
顯卡,
RTX 3080及RTX 3080 Super顯卡則有可能使用新增設的GA103核心。
前的RTX 2080 Ti是4352個CUDA核心,352bit位寬,11GB顯存,GDDR6速率14Gbps。
GA102核心擁有84組SM單元,總計5376個CUDA核心,配備384bit顯存,容量12GB,其性能
比RTX 2080 Ti高出40%。
最新的爆料則進一步確認了顯存規格——12GB沒跑
而且速率提升到了18Gbps,頻率、位元寬提升使得RTX 3080 Ti的頻寬高達864GB/s
提升了整整40%,逼近之前4組HBM2顯存的頻寬了。
頻寬提升40%,再加上CUDA核心數大漲,RTX 3080 Ti性能比RTX 2080 Ti高出40%的可能性
應該可以保證了
不出意外的話,RTX 3080 Ti顯卡的規格差不多是這樣,現在不確定的主要是工藝
是三星7nm EUV還是三星8nm LPP工藝,甚至是更低成本的三星10nm,一切都沒定數。
另外一個懸念則是發佈時間,上半年可能性基本排除了,悲觀的消息說是等到Q4季度,看
看big Navi的情況。
不過8月份發佈的可能性還是存在的,畢竟到年底還是太長了。
