史上最强APU！AMD新旗舰A10-7870K评测[74P]

A10-7870K、A8-7670K、A6-7470K……这就是AMD APU今年在桌面上的几乎全部努力了。没有全新架构，没有全新产品线，只有老款的改造升级，能带来什么惊喜吗？AnandTech近日就评测了刚刚发布的新旗舰型号A10-7870K，看看它能带来啥变化。

   这三款新APU(以及OEM领域的8000系列)内部代号是Godavari，也被称作Kaveri Refresh，就是去年Kaveri的升级版本，包括更好的工艺和芯片管理、一些小小的优化、更好的芯片分类和筛选、小幅度的电压提升(0.050V)，以及一些频率提升。仅此而已。

    A10-7870K还是基于压路机架构的CPU(Carrizo才用上了挖掘机)、GCN架构的GPU，但是频率更高了，CPU部分来到3.9-4.1GHz，分别只比A10-7850K提高了200MHz、100MHz，GPU部分则从720MHz来到了866MHz，大幅提升20％！可喜的是，热设计功耗功耗不变，还是保持在95W。

    价格也不错。A10-7850K首发的时候要172美元，如今已经降至135美元(国内799)，A10-7870K则一出来就只有137美元，国内目前报价也只有899元，相当实惠(当然也让老旗舰无地自容)。

    在这个价位上，对应的是Intel Haswell Core i3-4330，双核四线程3.5GHz，HD4600核显，热设计功耗54W。技术方面和以往没有任何不同，就不再多说了。

   刚才说到热设计功耗差很多，再来看看实际功耗吧(待机和满载的差值)。

   A10-7870K 117W，超过了热设计功耗标称，A10-7850K 85W还更低呢。虽然可能有个体差异的因素，但是0.05V的增压也不能忽略，难怪AMD附送了更大号的散热器呢。

    比起A10-7850K，九个项目竟然有五个反而倒退了，尤其是SunSpider退步很大。至于对比Intel，仍然是i3默全秒的节奏啊，只有在Google Octane里干掉了……节能版的i3-4130T。

Windows/Linux专业性能：好了一些

    这次比起A10-7850K好了很多，基本都是提升的，虽然多数时候幅度并不大。部分项目可以接近甚至超过i3，但总体还是差距比较明显。

低端显卡游戏性能：最强集显？NO

   游戏性能部分的测试规则参见此前的介绍。低端部分测试集成显卡、R7 240低端显卡，以及二者联合组成的Dual Graphics，测试分辨率基本是720p。

    20％的频率提升是不可能带来20％的性能提升的，但是每个游戏都或多或少有了些进步，对于想得到30/60FPS帧率的集显来说还是很有用的。双显卡受集显频率的影响更小，没啥变动。

    A10-7870K本来可以是最强集显的，但是刚刚发布的Broadwell Core i7-5775C、Core i5-5675C里边的Iris Pro 6200更加彪悍。问题是，Intel这两个家伙要366/276美元，贵得多，而且如此级别的用户，需要的肯定更多是独显。

    虽然CPU频率提升并不多，但值稍能带来一些性能进步的，尽管都是个位数。《异形：隔离》都可以超过120FPS了呢，如果再有支持AMD FreeSync的显示器，游戏就更顺畅了(当然用这种显示器的一般就也不会用APU)。

擦，这么专业的东西完全看不懂，话说，啥子叫APU额。。

回复 2楼 的帖子

APU不想配独显的话选择还是挺好的，上独显的话选APU又资源浪费
