AWS 推出使用 AMD CPU 的 m5a 與 r5a

Amazon EC2 推出使用了 AMD Epyc 的機種,分別為 m5a.*r5a.*:「New Lower-Cost, AMD-Powered M5a and R5a EC2 Instances」。

這個系列的重點在於價位相較於 m5.*r5.* 大約低了 10% 的費用:

The newest EC2 instances are powered by custom AMD EPYC processors running at 2.5 GHz and are priced 10% lower than comparable instances.


These instances are available now and you can start using them today in the US East (N. Virginia), US East (Ohio), US West (Oregon), Europe (Ireland), and Asia Pacific (Singapore) Regions in On-Demand, Spot, and Reserved Instance form.

然後在「Amazon EC2 Pricing」這頁已經可以看到價錢,但大概是某些非技術性的因素,可以發現沒有列出 ECU... 不過從沒有推出 c5a.* 系列大概可以猜測效能應該打不贏 c5.* 所以沒有打算推出對應的產品線?(不過也難說,等看看有沒有人測試出來吧...)

另外文章最後提到會有 t3a.* 的計畫,如果價錢會再比現在的 t3.* 低一些的話,看起來頗值得期待的:

PS – We are also working on T3a instances; stay tuned for more info!
