台北电脑展AMD强势崛起,不知英特尔明天的发布会会不会有惊喜?

在COMPUTEX 2019 台北电脑展正式开展前,AMD率先拉开了帷幕。AMD CEO Lisa Su(苏姿丰)在台北电脑展上一口气带来了多款全新的7nm产品,惹得观众席与屏幕前的观众惊叫连连。

此次发布会上,AMD带来了代号为”ROME”的第二代EPYC霄龙处理器,与一代产品相比,二代产品将每个Socket的性能以及I/O带宽提升到了2倍,浮点计算更是提升到了4倍。现场更是展示了与Intel Xeon 8280的对比,ROME处理器性能在其两倍以上。

对于游戏玩家来说,可能更为关心7nm制程的GPU。作为开胃甜点的关于下一代Playstation的消息就足以吸引众人眼球,苏姿丰明确表示下一代的Playstation将会采用AMD的7nm Radeon Navi架构(GPU)以及Zen 2架构(CPU)。

关于Navi苏姿丰也进行了十分详细的讲解,表示其将会是全新的7nm RDNA架构,并将拥有更快的时钟频率和更低的游戏功耗,也将会是世界首款支持PCIe 4.0的GPU。RDNA将会采用新的计算单元设计、多层缓存以及合理的图形算法去优化其表现。最终能够带来每时钟频率1.25倍表现提升,每瓦性能1.5倍的提升。

AMD随之推出了首款Navi架构的GPU——Radeon RX 5000家族。在展示过程中这款GPU对标的是英伟达RTX 2070显卡。AMD预期将在7月推出该系列显卡。并将在6月10日的E3游戏展爆料更多关于该显卡系列的详情。官方演示《奇异小队》视频中AMD该显卡帧数高过英伟达RTX 2070显卡10帧。

接下来,AMD公布了第三代Ryzen桌面处理器家族。三代CPU采用新的7nm Zen 2架构核心,3代AM4插槽CPU,同时也是世界首款支持PCIe 4.0的CPU。AMD带来了三款基于Zen 2架构的处理器,包括Ryzen 7 3700X、Ryzen 7 3800X、Ryzen 9 3900X ,计划于7 月 7 日发售。

Ryzen 7 3700X采用8 核 16 线程,基础频率 3.6GHz,最高频率 4.4GHz,TDP 65W,售价 329 美元。无论是单线程、多线程还是功耗,均相对于Ryzen 7 2700X有所提升。演示中性能测试对标对象为英特尔的i7-9700K。

Ryzen 7 3800X采用8 核 16 线程,基础频率 3.9GHz,最高频率 4.5GHz,TDP 105W,演示中性能测试对标英特尔的i9-9900K,售价 399 美元。

与此同时,AMD打出了世界首款PCIe 4.0游戏PC的旗号,采用Ryzen 7 3800X与Radeon RX5700系列显卡,X570主板,对标对象为i9-9900K与RTX2080Ti,在3DMark PCIe测试中,明显高过对标对象。

作为One More Thing(压轴)出现的Ryzen 9 3900X,采用了12 核 24 线程,基础频率 3.8GHz,最高频率 4.6GHz,TDP 105W,对标英特尔i9-9920X处理器,售价 499 美元。相对于英特尔i9-9920X而言,Ryzen 9 3900X单线程提升达14%,多线程提升达6%,CPU功耗则从i9-9920X的165W降到了105W。

AM4平台在迎来Ryzen 3900X后,与原平台支持的Ryzen 7 1800X相比,单线程提升高达32%、多线程提升高达100%。获得了实质性的提升。

如果单纯比较Ryzen 7 3700X与i7-9700K以及Ryzen 7 3800X与i9-9900K,可以看到,在单核上提升其实相当有限,基本上都是冲着1%的提升提升频率去的。而在多核上,由于Ryzen 7 3700X是8核16线程,而i7-9700K采用8核8线程,提升幅度相当明显,基本上达到28%左右。但是当同样8核16线程的Ryzen 7 3800X与i9-9900K相对比时,提升的幅度只剩下2%。也就是说Ryzen 7 3800X的碾压可能更多的来源于多线程的助力。但即便如此,玩家在选用处理器时也有了更多的选择。

比较有意思的是,在明天英特尔的发布会之前,英特尔已经公布了一款新的处理器,这款处理器将会是i9-9900K的特别版i9-9900KS,能够8核都达到5GHz的频率。但是其他详情并未公布。在AMD开始通过不同方式实现压制的时候,不知道明天英特尔的发布会会不会让我们感到惊喜?
