一、Zen横空出世 APU终于功德圆满

2017年无疑是AMD历史上最值得笔墨浓彩、大书特书的一年。Zen CPU架构的锐龙/霄龙横空出世、大杀四方,在各个领域都衔枚疾进,也让Intel放弃挤牙膏,全线提速,博得整个行业满堂喝彩,毕竟很久没有见过这么你追我赶的激烈局面了。

GPU显卡方面,AMD Vega新架构虽然并不尽如人意,不像Zen CPU那样风光无限,但有了新的GPU,AMD就可以再次双翼齐飞,Zen+Vega联手,带来了群众喜闻乐见、期盼已久的最新一代APU,甚至第一次走进了Intel处理器。

其实从2006年巨额收购ATI开始,AMD就一直在全力打造APU融合概念,不知不觉已经12个年头了,殊为不易。

从最早的CPU/GPU单纯物理整合、统一内存控制器,到后来的平台优化、CPU/GPU共享调度和功耗管理,再到CPU/GPU架构集成、统一寻址,到最终的CPU/GPU系统级融合,AMD一步一步走下来,历经七代产品,最终完成了梦想中的APU融合大计,将原本天各一方的CPU处理器、GPU显卡,牢牢捆绑在一起。

往大了说,APU开启了新的异构计算时代,CPU、GPU可以发挥各自优势,提高系统效率,而往小了说,APU可以为用户带来更统一、更具性价比的平台,不再需要单独购买显卡就可以获得足够好的图形、视频和游戏体验。

以往受制于架构设计和工艺水平,APU始终有一种无法使出全力的感觉,直到锐龙时代的到来。

二、锐龙APU解析:堪称梦幻

锐龙APU分为移动平台和桌面平台两种版本,不过和之前几代一样,锐龙APU也是首先登陆移动平台,先从笔记本入手,再次凸显了AMD对笔记本市场的重视,并且在未来,AMD移动市场上将只会有APU,而不再有单独的CPU。

全新一代APU采用最先进的GlobalFoundries 14nm制造工艺,同时集成Zen CPU、Vega GPU两套新架构,以及DDR4内存控制器、多媒体引擎、显示引擎、IO和系统中心,统一使用Infinity Fabric高速通道紧密联系在一起。

这种新工艺新架构加上统一高速互连的设计相当巧妙,决定了锐龙APU内部是一个有机的整体,也是AMD APU融合理念的终极完美产物。

12年炼成锐龙APU:还要啥独显?

2017年第四季度,锐龙APU就率先冲入了笔记本市场,先发两款高端型号,分别是Ryzen 7 2700U、Ryzen 5 2500U,都采用了4核心8线程设计,同时分别集成640个、512个流处理器,热设计功耗仅仅12-25W。

2018年第一季度,锐龙APU又新增了两款主流型号Ryzen 3 2300U/2200U,分别是4核心4线程、2核心4线程(Zen家族唯一的双核心),分别有384个、192个流处理器。

另外凭借AMD GPU一贯丰富的技术优势,锐龙APU也支持各种视频编解码、4K超高清输出、HDR10高动态范围显示、FreeSync/FreeSync 2显示变频等等,可以让笔记本轻松变成影音娱乐中心。

锐龙APU号称最快的移动处理器,从规格上看名副其实,而且是在区区1.38毫米的厚度下做到的,实属奇迹,非常适合打造高性能的轻薄笔记本。

锐龙APU的推出,也得到了笔记本厂商的迅速响应,宏碁、戴尔、惠普、联想等都已经陆续推出各自的新本,用户也多了一种全新的选择。

、平台对标:完全可替代八代酷睿+独显

说了半天,锐龙APU的实际性能表现到底如何呢?能不能给笔记本带来改天换地一般的新变化呢?一切显然还是要靠实际数据来说话。

为了说明问题,这里我们选择了笔记本媒体圈里最权威的NotebookCheck的一份详细测试,看看锐龙APU的CPU性能、GPU性能以及功耗表现。

本次测试的锐龙APU笔记本是来自惠普的Envy x360 15m-bq121dx,配备一颗次顶级的锐龙APU Ryzen 5 2500U,同时还有8GB DDR4-2333双通道内存(APU对内存很敏感的)、HGST 1TB 7200转硬盘。

CPU性能我们参考最权威、最有说服力的CineBench R15:

可以看出,Ryzen 5 2500的单线程性能已经比较接近八代酷睿的Core i5-8250U,多线程性能更是几乎完全持平。

GPU性能先参考同样权威的3DMark:

更加惊喜,512个Vega架构流处理器的Ryzen 5 2500U已经轻松超越NVIDIA上一代主流的独立显卡GeForce 940MX,以及Intel最顶级的核芯显卡Iris Pro 580,并且十分接近NVIDIA这一代主力独立显卡、也是很多笔记本中相当常见的GeForce MX150。

只有实际游戏,我们看看火爆的《英雄联盟》:

12年炼成锐龙APU:还要啥独显?

1080p中等画质下,帧率轻松达到40-60FPS,完全可以流畅战斗。

如果换成顶级的Ryzen 7 2700U,CPU性能媲美Core i7-8550U,GPU性能超越GeForce MX150那也是小菜一碟了。

对于笔记本平台,功耗问题当然也是焦点,毕竟这关乎续航能力:

12年炼成锐龙APU:还要啥独显?

Ryzen 5 2500U笔记本的负载功耗、游戏功耗只有45-50W左右,大大低于Core i5-8250U+GeForce MX150的组合,日常使用中高负载四五个小时、轻负载十个小时是很轻松的。

这意味着,如果你带着锐龙APU笔记本出门,不但可以获得足够高的综合性能,还可以好不担心地用上一整天。

四、总结:轻薄本不要独显也能有流畅游戏体验

其实在Zen架构的Ryzen锐龙处理器诞生之后,大量用户一边感慨AMD回来了,一边等着基于新架构的新APU,期盼它带来更高性价比的新平台,无论桌面还是笔记本。

更要命的是,受到虚拟电子货币挖矿的刺激,这一年多来的独立显卡市场被彻底搅乱,大量显卡被矿工买走,导致普通用户、玩家想买一块称心如意的显卡都无比艰难,高性能的集成显卡就成了新的选择。

笔记本上虽然不需要单独购买显卡,但对于轻薄笔记本来说,如果加入独立显卡,势必会占用内部空间,影响其他配置的提升,同时也会加大机身尺寸和重量、增加功耗和发热,整机成本也会水涨船高。

Intel处理器虽然全线集成核芯显卡,但都是越高级的型号,核显越强,但高端型号又不适合做轻薄本,GeForce 940MX、MX130、MX150这类独立显卡就成了热门。

锐龙APU则带来了一股新鲜空气,14nm新工艺、Zen CPU新架构、Vega GPU新架构,再加上各种视频图形技术,实现了很多用户的期盼。

锐龙APU的实际表现也令人满意,CPU性能达到了和Intel八代酷睿的同样水准,GPU性能则一举超越940MX、MX130、MX150这样的独立显卡,而且功耗发热控制得当。可以说,未来的轻薄笔记本,完全可以在不配备独立显卡的情况下,获得足够好的游戏体验。

目前,锐龙APU笔记本正在陆续诞生,但还不够丰富,希望未来能有越来越多的锐龙APU笔记本,让这个市场更加丰富。
