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-1 的 m6a.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).
