Intel Sapphire Rapids第四代可扩展至强原计划2021年发布,但因为瑕疵太多,一再跳票,目前仅出货了少数评估样品给客户,消息称正式发布要到明年第二季度,推迟足足两年。
创新大会上,Intel首次公开展示了新至强,并首次进行了跑分,还是60核心顶级版本。
正面照,被散热顶盖捂得严严实实,还是工程样品。
背面照,新的LGA4677封装,触点密密麻麻。
展示使用的服务器,八通道DDR5内存。
Sapphire Rapids至强的一大特点就是集成了各种专用加速器模块,包括动态负载均衡器(DLB)、数据流加速器(DSA)、内存内分析加速器(IAA)、快速助手技术(QAT),都可以为特定负载加速,减轻CPU负担。
其中,QAT是从芯片组转移到CPU内部,其他则都是全新的。
CPU还支持高级矩阵扩展(AMX)、AVX-512。
跑分测试很多,也对比了AMD霄龙,但都是服务器应用,就不细说了,感兴趣的自己看吧。
