解析高通正式发布的骁龙730等三款中端芯片 堪称为所欲为

如果说在智能手机的高端市场还有海思麒麟和三星猎户座能与高通勉强一较高下,那么在中低端市场,在高通看来,真的一个能打的都没有。这也是近两年我们看到高通在中端芯片市场越来越为所欲为的原因。6系7系命名混乱不堪,性能也并没有严格的分级,甚至连骁龙712这样的官超版芯片也是给钱就给你单独发。

就在昨晚,高通又正式发布了三款中端移动处理器,骁龙665、骁龙730和骁龙730G。准确的来说是两款,因为骁龙730G与骁龙730除了GPU频率提高并无其他差别。我们一起从这几款新芯片的参数看看高通有多么为所欲为吧。

骁龙665——如果不是用在千元机上,那么将毫无意义。

从型号命名上面来看,我们很容易将它与一代神U骁龙660联系起来,事实上也确实如此,骁龙665确实是作为骁龙660的接班人来发布的。

骁龙665采用了三星的11nm LPP工艺制程,相比此前的14nm工艺有所升级,但CPU部分却较骁龙660有所降低。同为4+4的八核架构和 Kyro 260核心(A73),小核心(A53)频率同为1.8GHz,但大核心频率却从2.2GHz降到了2.0GHz。在工艺制程提升的同时降低了频率,看样子高通想把它打造成一款功耗控制无敌的芯片,至于性能方面差点就差点吧。

在其他方面骁龙665倒是有着常规的升级,GPU从Adreno 512升级到了Adreno 610,最大的升级便是支持了Vulkan,DSP也升级到了Heagon 686 DSP、Spectra 165 ISP,功耗相对降低20%,AI性能提升了2倍。骁龙665也支持4800万像素单摄并支持三摄镜头,这也是现在最流行的摄像头配置。

虽然纸面上的提升还是喜人的,但相对于如今遍地的骁龙675、骁龙710中端机来说,这点提升还是不可能做到越级吊打的。所以无论骁龙665升级多少,也不管它是否是全新的处理器,它的各项配置决定了它只能是一款千元机芯片。并且考虑到功耗控制和性能表现,骁龙665还会是一颗非常不错的入门级芯片。

反正大家都看不起骁龙4系列芯片,直接用6系列芯片来做入门级也未尝不可。

骁龙730、骁龙730G——终于称得上是真正的准旗舰了

回想小米9SE发布的时候,小米将小米SE定位为小屏旗舰,高通还专门超频了骁龙710专门发布了一款骁龙712芯片来支撑小米9SE的定位。但表现如何大家应该也清楚,CPU部分甚至被骁龙675越级痛打,准旗舰定位不攻自破。这次的骁龙730则是为了扶正骁龙7系列准旗舰定位而生的。

骁龙730用上了仅次于旗舰的制程工艺,也是高通第一次用上了三星的8nm制程工艺。并且用上了最新骁龙855旗舰同代的架构Kryo 470,采用8核心设计,由两个2.2GHz的Kryo 470(A76)大核心和6个1.8GHz的Kryo 470(A55)小核心组成。8nm的工艺加上A76的架构,这样的CPU绝对称得上目前最强的中端芯片,CPU性能相比710提升了35%。

GPU部分小幅度升级,型号为Adreno 618,骁龙730G的GPU也同样为Adreno 618,不过频率更高,有15%的性能提升。从官方的数据来看,骁龙730G图形性能大约是目前中端芯片中最强的,但是比起骁龙8系列的旗舰来说,还是差得远。严格来说,骁龙730可能接近了三年前骁龙820的GPU水平吧。高通一直以来在中端芯片的GPU方面非常的抠门,虽然绝对性能表现不如人意,但是凭借着高通的专业优化,应对目前主流游戏还是没有问题的。

骁龙730的其他方面则是有了较大的升级,接近了高通骁龙855水平,多项新技术也是高通第一次从旗舰8系下放。最新Hexagon 688 DSP,包括高通的张量加速器,配合高通第四代AI引擎,AI处理性能比之前提升2倍。图像方面集成Spectra 350 ISP,支持CV计算视觉加速,真 HDR画面的支持等技术也都是此前8系旗舰芯片才有的功能。其他的对内存的支持和基带等方面则没有太大变化,都属于够用级别。

至此,骁龙7系列才算是真正的定位在了准旗舰,除了GPU,其他方面都更加接近了旗舰定位的骁龙855。虽然综合性能还是比不过上代旗舰,但一般厂商也必然会在价格上面保持克制,不会超过上代旗舰的水平。

最后附上来自Anandtech的骁龙中端芯片对比图,可以清楚的看到6系和7系芯片的不同之处。由于新加入了两款芯片,高通的中端芯片可以说更加的混乱不堪。普通消费者可能很难分辨其中的差异,仅凭数字已经不能准确判断它们的性能高低了。甚至高通还很可能就此开启厂商定制版本,只要厂商愿意,高通随时大刀一挥,为其提供一款专属芯片。没办法,没有竞争就是如此的为所欲为。
