AMD Radeon R9 270X

AMD Radeon R9 270X

最早发布与2013年10月的Radeon R9 270X是一款中高端的台式机显卡。它基于“Curacao”架构,并使用了28纳米制程技术。这款显卡提供了1280个着色器单元和256位的显存位宽(支持2GB GDDR5显存和179GB/s的带宽)。 架构 Radeon R9 270X使用了和上代的Radeon HD 7870相同的核心。Curarao架构,以前也常作Pitcairn,基于GCN架构并提供了1280个着色器,80个TMU和32个ROP。相较于HD 7870,R9 270X有相对略高的1050MHz核心频率(最大速度)和1400MHz(有效值5600Mhz)的显存频率。和更快的R9 290X一样270X支持DirectX 11.2(仅Tier-1),但缺少对新的Trueaudio技术的支持。 性能 根据游戏和设定的不同,Radeon R9 270X的性能表现和Nvidia GeForce GTX 760相当。因此即使是最快的移动显卡如GeForce GTX 780M也在性能上相比270X略逊一筹。大型游戏如《地铁:最后的曙光》可以在1920x1080分辨率和高设定下流畅运行。使用更高的分辨率或额外打开AA/AF抗锯齿技术在一些情况下也能够运行。 特性 R9 280X支持一些常见的功能如Eyefinity,同时也支持另外一些革新性的技术,如新的turbo加速模式。根据功耗和核心温度,显示核心频率可以提高到1050MHz。不过,这个加速并没有官方的底频限制即最低的频率限制。 功耗

得力于动态的频率调整,和Zero Core技术的帮助,R9 280X在待机状态下有很高的功效。在高负载下,这款显卡的典型功耗为180W。
