<p><strong>加密数量再升级</strong></p>

<p><span>Ampere<span>&nbsp;</span></span><span>Altra</span><span><span>&nbsp;</span></span><span>Max的</span><span>实验室的测试结果显示，在进行</span><span>AES-256-gcm</span><span>加密计算时，</span><span>它</span><span>可以加密的数据块比</span><span>Ampere<span>&nbsp;</span></span><span>Altra</span><span>多出</span><span>57</span><span>％，所用密钥大小从</span><span>16</span><span>到</span><span>16K</span><span>字节不等。加密是许多云工作负载中的一项基本任务。高级加密标准（</span><span>AES</span><span>）是一种快速、安全的对称分组密码，已在业界和美国政府中广泛使用。</span></p>

<p><strong>媒体编码新王者</strong></p>

<p><span>测试结果表明，</span><span>Ampere<span>&nbsp;</span></span><span>Altra</span><span><span>&nbsp;</span></span><span>Max</span><span>每秒编码帧</span><span>数比</span><span>Ampere<span>&nbsp;</span></span><span>Altra</span><span>高出5</span><span>5%</span><span>。而过往的测试显示，</span><span>Ampere</span><span><span>&nbsp;</span></span><span>Altra</span><span>的编码性能已经领先于当前的</span><span>x86</span><span>处理器（如图</span><span>2</span><span>所示），</span><span>Ampere<span>&nbsp;</span></span><span>Altra</span><span><span>&nbsp;</span></span><span>Max则比</span><span>Ampere</span><span><span>&nbsp;</span></span><span>Altra</span><span>更强</span><span>。</span></p>

<p><span>软件媒体编码仍然是云中流行的工作负载，</span><span>h.264</span><span>是当今在线使用的最流行的视频编解码器。编码媒体是质量和吞吐量之间的平衡，通常利用配置文件、分辨率和比特率的特定组合对尽可能多的片段进行编码。</span></p>

<p><strong>NGINX<span>&nbsp;</span></strong><strong>开挂新神器</strong></p>

<p><span>测试</span><span>结果显示</span><span>，</span><span>在搭载</span><span>Ampere<span>&nbsp;</span></span><span>Altra</span><span><span>&nbsp;</span></span><span>Max的情况下，</span><span>NGINX Web</span><span>服务器的</span><span>p.99</span><span>延迟</span><span>SLA</span><span>（服务水平协议</span><span>）</span><span>为</span><span>10ms</span><span>，吞吐量比</span><span>搭载</span><span>Ampere<span>&nbsp;</span></span><span>Altra</span><span>的情况下</span><span>高</span><span>51</span><span>％。</span><span>NGINX</span><span>是一种高性能、轻量级的</span><span>Web</span><span>服务器，也可以用作反向代理，负载平衡器，邮件代理和</span><span>HTTP</span><span>缓存。</span><span><span>&nbsp;</span>Web</span><span>服务器的性能指标通常是在指定的</span><span>SLA</span><span>下的吞吐量或每秒请求数，例如</span><span>p.99</span><span>延迟。</span></p>

<p><strong>Ampere</strong><strong>重磅力作，云上新王者</strong></p>

<p><span>总体而言，</span><span>Ampere<span>&nbsp;</span></span><span>Altra</span><span><span>&nbsp;</span></span><span>Max不仅内</span><span>核数大幅提升，还将其可扩展性转化为超过</span><span>50</span><span>％的实际性能提升。</span><span><span>&nbsp;</span></span><span>Ampere</span><span>保持着快速的产品开发节奏，并每年带来突破性的性能提升。</span><span>Ampere将</span><span>推出的新产品能够在现代的工作负载下表现出色，并能够比其他</span><span>CPU</span><span>产品</span><span>为用户带来更高的收益。</span></p>

<p><span>Ampere 应用工程高级总监</span><span>Naren Nayak</span><span>表示：“</span><span>我们承诺，将保持快速且可预测的产品发布节奏。云服务提供商也认为这是保持可持续、快速增长的先决条件。</span><span>Ampere<span>&nbsp;</span></span><span>Altra</span><span><span>&nbsp;</span></span><span>Max</span><span>是我们产品计划中的又一个重大飞跃，它有望在几个月内投入生产。</span><span>Ampere<span>&nbsp;</span></span><span>Altra</span><span><span>&nbsp;</span></span><span>Max</span><span>专为横向扩展而设计，同时延续了我们内核密度行业领先的一贯风格——</span><span>具备</span><span>128</span><span>核。</span><span>60</span><span>％的内核数提升也大幅地提高了</span><span>Altra</span><span><span>&nbsp;</span></span><span>Max</span><span>的可扩展性，这让它非常适用于云原生架构。难以想象，四年前，服务器处理器的最高核数是</span><span>32</span><span>核</span><span>。”</span></p>

<p><span>Naren Nayak</span><span>补充道：“</span><span>在</span><span>Ampere</span><span>，除了云原生处理的两大核心需求——可预测的高性能和高能效比之外，我们还坚定地致力于持续提升产品的横向扩展性，这在</span><span>Ampere<span>&nbsp;</span></span><span>Altra</span><span><span>&nbsp;</span></span><span>Max</span><span>中得到了充分的体现。未来几个月，我们将公布更多关于新品</span><span>Altra Max</span><span>的信息，欢迎继续关注。”</span></p>
