AWS 推出 c7g 機種

AWSAmazon EC2 產品線上推出了新一代的 ARM 產品,AWS Graviton3 架構,c7g 系列機種:「New – Amazon EC2 C7g Instances, Powered by AWS Graviton3 Processors」。

Graviton3 宣稱比 Graviton2 多 25% 的一般性效能,以及多了一倍的浮點效能,還有 DDR5 的頻寬優勢:

Our next generation, Graviton3 processors, deliver up to 25 percent higher performance, up to 2x higher floating-point performance, and 50 percent faster memory access based on leading-edge DDR5 memory technology compared with Graviton2 processors.

在「FreeBSD on the Graviton 3」這邊也可以看到一些效能數據 (雖然是跑在 FreeBSD 上),可以看到基本上符合 AWS 的宣稱。

目前只有 us-east-1us-west-2 有這個機種,不過 Graviton 系列一直都是 AWS 的強主打項目,其他區域應該很快就會看到:

C7g instances are initially available in US East (N. Virginia) and US West (Oregon) AWS Regions; other Regions will be added shortly after launch.

價位上比 c6g 貴了一些,在 us-east-1c7g.16xlarge (64 vCPU + 128 GB RAM) 是 US$2.32/hour,而 c6g.16xlarge 是 US$2.176/hour,大約貴了 6.6%,但如果是 CPU bounded 的應用來說,應該還是蠻划算的。

另外一方面是等後續的 m7gr7g 系列出現...

Amazon EC2 推出 c6a 的機器

Amazon EC2 以新的 AMD 架構 (雖然也推出一陣子了) 的機器推出 c 系列的機種,代號為 c6a:「New – Amazon EC2 C6a Instances Powered By 3rd Gen AMD EPYC Processors for Compute-Intensive Workloads」。 價位上與 c5a 相比便宜一點點,是真的一點點:在 us-east-1 的 c5a.24xlarge 是 US$3.696/hr,而 c6a.24xlarge 是 US$3.672,差 0.65% 左右... (千分之六點五 XD) 所以宣稱的 15% 基本上都是從 CPU 效能提昇貢獻的: Up to 15 percent improvement…

AWS 要推出 Graviton3 的機種了

AWS 打算要推出 Graviton3 的機種了,目前還在 preview 階段:「Join the Preview – Amazon EC2 C7g Instances Powered by New AWS Graviton3 Processors」。 目前是宣稱與前一代的 Graviton2 相比有 25% 的效能提昇,另外在浮點數與密碼相關的運算上面也會有改善 (這個效能提昇的數字應該是有指令集的幫助): In comparison to the Graviton2, the Graviton3 will deliver up to 25% more compute performance and up to twice as much floating point & cryptographic…

Amazon EC2 的 M6g 系列正式推出了

先前提到 AWS 要在 EC2 上推出新的 ARM 架構主機 (參考「Amazon EC2 推出了新一代的 ARM 系統」這篇),最近正式推出了:「New – EC2 M6g Instances, powered by AWS Graviton2」。 當時的定價還沒出來,現在正式開賣後可以拉出來看了。 拿 us-east-1 上 2 vCPU + 8GB RAM 這個級距的價錢出來,m5.large 是 USD$0.096/hour,m6g.large 是 USD$0.077/hour,低大約 20%,不過這是兩個不同的平台,只是抓一下感覺知道差距。 不過這個價差其實蠻有吸引力的,對於有支援 ARM 的應用程式,或是手上有 source code 的大型應用,可以測試看看效能有差多少,或是先等一下,這陣子應該就會有人初步測一些數字出來可以參考。 另外 AWS 有打算要出 C6g 與 R6g 的計畫,算是在雲上面補齊 ARM 的戰線:…
