Amazon EC2 推出 m7a 系列的機種

上一篇完全讀錯段落了,重寫...

Amazon EC2 推出了新的 m7a 的機種:「New – Amazon EC2 M7a General Purpose Instances Powered by 4th Gen AMD EPYC Processors」。

號稱與 m6a 相比有 50% 效能上的提升:

Today, we’re announcing the general availability of new, general purpose Amazon EC2 M7a instances, powered by the 4th Gen AMD EPYC (Genoa) processors with a maximum frequency of 3.7 GHz, which offer up to 50 percent higher performance compared to M6a instances.

不過查了一下價錢,us-east-1m6a.large 是 $0.0864/hr,m7a.large 則是 $0.11592/hr (都是 2 vCPU + 8GB RAM),漲了 34% 左右,如果計算 price performance 的話大約是 10%~15%?的確是不高所以不提 price performance,不過這次 m7a 提供了更小台的 m7a.medium (1 vCPU + 4GB RAM) 來補這塊 (m6a 最小的是 m6a.large),$0.05796/hr。

這樣看起來新的機種對於需要單核效能的應用應該會不錯?

再來是可以租到的區域,目前看起來只有歐美的傳統大區有,亞洲區還要再等等:

Amazon EC2 M7a instances are now available today in AWS Regions: US East (Ohio), US East (N. Virginia), US West (Oregon), and EU (Ireland).

  1. 剛剛注意到phoronix的review文章有提到:
    https://www.phoronix.com/review/aws-m7a-ec2-benchmarks
    > All of the instances are counting 1 vCPU as 1 physical core and thankfully refraining from counting the SMT sibling thread as a vCPU (SMT is off).

    不曉得是本來的產品規劃就是這樣,還是針對AMD Inception vulnerability的措施呢?
    但大概是因為這個理由所以多了m7a.medium可用。
