晶晨Amlogic S905X参数性能，怎么样

分析如下：

1、Amlogic S812是晶晨最新最强的芯片，已经量产，但是国内目前用这个芯片的电视盒还不多，除了影驰芒果盒，还有小米盒子增强版、泰捷webox增强版以及天敏D6升级版，可以肯定的是下半年会有越来越多使用这个高性能新品的盒子出现。

核心架构是四核Cortex-A55，整数计算能力(DMIPS)较高，可达21800+.DMIPS。晶晨半导体（上海）股份有限公司（曾用名：晶晨半导体（上海）有限公司），成立于2003年，位于上海市，是一家以从事计算机、通信和其他电子设备制造业为主的企业。企业注册资本41112万，实缴资本26021.440689万，并已于2020年完成了股权融资。

Mstar 6A938是电视芯片制造商Mstar(晨星)推出的2016年最新旗舰级电视芯片“极光”的具体型号。熟悉电视配置的朋友多少都会听说过“Mstar”这个芯片品牌，“Mstar”是最大的全球电视芯片生产商，事实上，据称全球50%以上的智能电视都采用Mstar芯片，包括一些国外一线品牌。6A938是上一代6A928芯片的升级产品，也是2016年Mstar的旗舰芯片，这款Mstar 6A938采用了目前最新的Cortex-A72CPU(上一代6A928芯片采用Cortex-A17 CPU)，且采用了Mstar CoreTurbo真多核驱动引擎GPU方面则采用了Mali T820，使得4K条件下的游戏、UI最高可达60FPS另一方面，6A938采用96bit的DDR4内存，频率可达2.4GHz。从参数上我们可以看到6A938相比前一代6A928芯片，在CPU、GPU和内存上都有了不小提升，而在实际跑分方面，从目前曝光的数据看，6A938的CPU性能比上一代提高86%，总分提高40%。有评论文章称Mstar 6A938就是手机界的高通820。Amlogic，也就是晶晨半导体，与手机中定位中低端产品的MTK一样，其产品多在电视机顶盒、电视盒子等产品上使用，例如我们熟悉的小米盒子、天猫魔盒、乐视盒子等，很多都是用的Amlogic的芯片。Amlogic T966在2015年第四季度就已经发布，同时发布的还有T968。T966这个SOC芯片中分别使用了4核A53 CPU，Mali T830 MP2，并使用了64位设计，支持4K H.265@60fps 10-bit和HDR10解码。表面数据看上去很美么？但实际上CPU单元的4核Cortex-A53定位只是中低端，因为晶体管数量少，制造工艺简单。与Mstar 6A938处理器来对比的话，其CPU单元包含2核Cortex-A72和2核Cortex-A53，一颗Cortex-A72核心面积相当于4个A53核心的面积。一个6A938就相当于8个A53（2个A72核心）+2个A53的配置，等于10核A53。
