測試不公?intel 反駁 Rome 比 Xeon 性能高 2 倍的歪理!
http://tinyw.in/p8gA
原文:
前幾天 AMD 發布了第二代 EPYC 處理器,這款處理器代號羅馬(Remo),基於 Zen 2 架
構,採用 7 nm 工藝,最高 64 核心 128 線程,主要客群為數據中心。並現場展示了其
與 Intel Xeon 鉑金 28 核處理器 8280 的對比,測試顯示 Xeon 8280 性能為每天
9.68ns,64 核 AMD 二代 EPYC 性能為每天 19.6 ns,性能提升了一倍以上。現在,
intel 開始發聲稱 AMD 的對比不准確、不客觀。
據 tomshardware 報導,intel 表示 AMD 的對比有兩個問題,其一是對比的 8280 平台
沒有被優化,沒有採取最佳的設置,其二是拿 64 核處理器對比 28 核處理器本就不公平
。intel 表示,在對系統進行正確的優化之後,其運行測試得出的結果比 AMD 發布會上
提供數據高出了 30%。當然了,即使提高了 30%,8280 平台的最終結果還是落敗於 64
核羅馬處理器。隨後 intel 還拿出了核心更多的 Xeon Platinum 9000 系列(Cascade
Lake -AP)來對比 AMD 的 64 核羅馬處理器。其 48 核心的 Xeon 9242 相比 64 核羅馬
處理器性能高出 1.5%,而 56 核心的 Xeon 9282 相對於 64 核羅馬處理器性能高出 23%
。
但是對於服務器處理器來說,由於其全天候運行,所以 TDP 也一直是個非常需要著重考
慮的因素。intel 的Xeon 9282 和 Xeon 9242 其 TDP 分別為 400W 和 350W,而 AMD
的 64 核羅馬處理器由於採用了 7 nm 工藝,據稱 TDP 最大為 240W(AMD尚未正式確認
)。
intel 此番對一個基準測試進行反駁是很少見的一個行為,主要原因是這其中的厲害關係
對 intel 來說很重要。因為數據中心這塊一直是英特爾的營收最大頭,英特爾去年的數
據中心業務方面賺取了 340 億美元,這其中包括存儲、內存和網絡產品,所有這些都受
益於 intel 在數據中心處理器市場佔據的市場份額,其數據中心銷售額現在約占公司總
收入的 50% 之多。而 AMD 的第二代 EPYC 處理器現在正在威脅 intel 這塊大蛋糕,所
以 intel 才會做出如此少見的一個行為。
心得:
AMD不要臉~~
i皇就已經指名過核心數不重要???
只會用核心更多,發熱更少,價格更便宜這些不重要的東西宣傳
還是我大i皇實在在做事,
也告知跑分太低是你忘了優化,沒有採取最佳的設置
買intel記得指名"冷水機"
