buyvm近期将陆续更换为AMD处理器，未来将开展服务器迁移工作
据可靠消息，2月25日，buyvm的母公司加拿大主机商frantech宣布将开始对旗下VPS主机品牌buyvm的服务器处理器由英特尔更换为AMD，原因是英特尔的处理器存在漏洞，要更换为AMD的处理器。关于处理器行业英特尔和AMD的竞争那不用我多说，从个人电脑上两家的竞争到服务器领域的竞争那可谓是旷日持久，无论是企业、IDC、服务商还是用户一直以来对处理器到底谁家好至今仍存在着巨大的争论，一般我们熟悉的大型云服务商比如亚马逊、谷歌、微软、阿里云之类的以及大型的VPS服务商vultr这样的大多选择Intel的处理器，无论是个人PC还是服务器Intel几乎接近垄断，但也有比如ramnode、腾讯云（AMD为特别产品，本质上还是在用Intel处理器）都选择使用AMD的处理器。无论是选择谁家只要处理性能更好就行，管他呢又不是换了处理器就不好用了。
buyvm预计下周也就是3月份开始首先对拉斯维加斯机房进行处理器更换，一同升级的不只是换AMD处理器，带宽也会从1Gbps增加到10Gbps，还会更换成高频处理器，时钟主频也会从3.5GHz升级到3.8GHz，增强时钟主频可超过4GHz，SSD硬盘也会从SATA固态硬盘换成NVMe的高效固态硬盘，这一配置几乎是相当于跟高频CPU的vultr、ramnode差不多了。官方还计划4月对纽约机房进行更换调整，年内对最后一个机房欧洲的卢森堡机房进行调整，暂时不会对卢森堡机房进行调整。总之本次升级也是干货满满，同样也计划对使用超过6个月以上的老用户提供特殊福利，取消入站速度也就是访问速度的限制（尚未实施）。
以下是公告原文和翻译：
Announcing the BuyVM hardware refresh to AMD Ryzen!
New Year, New… Intel exploit? Sigh.
Since the launch of our KVM Slices, we have used Intel 1270v3 CPUs with SATA SSD storage. This setup has treated us well with performance that does not break the bank. Unfortunately, Intel CPUs have lost their performance advantage over the last 2 years due to design flaws that have led to security exploits/vulnerabilities.
You would have most likely heard of these exploits/vulnerabilities by the names ‘Meltdown’, ‘Spectre’, and ‘MDS’.
While these exploits/vulnerabilities can be mitigated in software, this comes at the cost of performance. Estimates show a performance loss of around 30% when these mitigations are enabled (and even more if HT/SMT is disabled).
Today we are happy to announce a complete overhaul of all of our KVM Slice nodes to AMD Ryzen 3900X CPUs. Our originally advertised 3.5GHz clocks will increase to 3.8GHz with a boost clock of 4GHz+ (we are seeing an average boost clock of 4.1GHz on most cores). Storage will also be upgraded from SATA SSDs to NVME SSDs, which will increase IO performance by 4x or more.
Network connectivity will be upgraded from 1Gbit to 10Gbit. While your service will remain capped at 1Gbit in each direction, we are considering uncapping inbound speeds for long term customers (customers who have had an active service for >6 months for example). We haven’t given this too much thought yet but many users have shown interest in veteran perks.
Last but not least, A+B power will be set up in Las Vegas to protect us from the Homer Simpsons that always seem to end up working on our power panels. This has been in the works for a while but has only recently become possible.
We have begun ordering equipment for Las Vegas and expect to be racking the new nodes in the next week or so. You will receive an email soon that will document when your VPS will be migrated. A reboot will be required upon which your Slice will automagically be migrated to our new nodes.
We expect to get New York done by early April and will be taking this opportunity to bring our Block Storage Slabs online with new network connectivity (ideally, NYIIX & Hurricane Electric). A new Juniper router will also be installed.
Luxembourg upgrades are for the moment up in the air, but we hope to complete them this year as well.
We thank you for your patronage and are excited to see what you think of our new nodes!
BuyVM处理器更新为AMD Ryzen！
新年，新。。。英特尔漏洞？叹息。
自从我们的KVM服务器发布以来，我们使用了带有SATA SSD存储的Intel 1270V3 CPU。这种安排对我们的表现很好，没有出现啥问题。不幸的是，由于设计缺陷导致安全漏洞/漏洞，英特尔CPU在过去两年中失去了性能优势。
您很可能听说过这些漏洞/漏洞的名称为“崩溃”、“幽灵”和“MDS”。
虽然这些漏洞/漏洞可以在软件中得到缓解，但这是以性能为代价的。据估计显示，当启用这些缓解措施时，性能损失约为30%（如果禁用了HT/SMT，则损失更大）。
今天，我们很高兴地宣布对所有KVM节点进行全面检修，届时节点将全部更换为AMD Ryzen 3900X CPU。我们最初宣传的3.5GHz时钟主频将增加到3.8GHz，增强时钟主频为4GHz+（我们看到大多数内核的平均增强时钟主频为4.1GHz）。存储也将从SATA SSD升级到NVME SSD，这将使IO性能提高4倍甚至更多。
网络连接将从1Gbit升级到10Gbit。虽然您的服务在每个方向上都将保持在1Gbit的上限，但我们正在考虑为长期客户（例如，已使用服务超过6个月的客户）取消入站速度的限制。我们还没有考虑太多，但许多用户已经表现出对老用户福利的兴趣。
最后但并非最不重要的是，A+B电源将在拉斯维加斯建立，以保护我们的电源板能顺利的工作结束。这项工作已经进行了一段时间，但直到最近才成为可能。
我们已经开始为拉斯维加斯订购设备，预计在下周左右将安装新节点。您将很快收到一封电子邮件，其中将记录您的VPS将被迁移的时间。需要重新启动，然后您的节点将自动迁移到我们的新节点。
我们预计在4月初完成纽约的工作，并将借此机会使我们的块存储板与新的网络连接（理想情况下，NYIX和Hurricane Electric）联机。还将安装一个新的Juniper路由器。
卢森堡的升级目前还没有定论，但我们希望今年也能完成。
感谢您的惠顾，我们很高兴看到您对我们新节点的看法！
