尝试 DigitalOcean AMD VPS 并测试其性能

过去那些年的 VPS 服务商一直是用的 Intel 的 CPU,所以我用的也只能是 Intel 的,测试性能也只有这个。现在可以用 AMD 的 EPYC 的CPU了。于是今天就来开一台 DigitalOcean 的 Premium Droplet,用的是 AMD CPU。
官方的说明是
AMD Premium Droplets 目前运行基于 "Zen 2 "架构的第二代 AMD EPYC™ 处理器,其特点是通常所说的罗马架构。这些 AMD EPYC CPU 的基本频率为2.0 GHz,最大Turbo 频率为3.35 GHz。

以上是新建 VPS 登录后,直接做的测试,接下来,第二次做测试之前,先更新系统,在修改 TCP CC 为 BBR,在重启之后,做的测试。

截图的结果:
amd-premium-droplet-bench.jpg
跟我之前新建的 Intel 的 Droplet 比起来,好像IO性能更好。

虽然在系统里面看不到实际的 CPU 型号,但可以从 Digital Ocean 透露的信息,我猜测的 AMD CPU 是 AMD EPYC 7702。 Intel CPU 是 Intel Xeon Gold 6248

在使用另外一个测试工具做了测试。

Geekbench 5 Benchmark Test:
---------------------------------
Test            | Value

Single Core     | 861
Multi Core      | 854
Full Test       | https://browser.geekbench.com/v5/cpu/6754972
可以看一下 Geekbench 5 性能比较,同当前我在用的 DigitalOcean 普通的SSD VPS 比较,稍微好一点。https://browser.geekbench.com/v5/cpu/compare/6736921?baseline=6754972

接下来,就打算把原来我用的普通 DigitalOcean VPS 换成这个 AMD Premium Droplet。
