AMD Radeon HD 6870M

AMD Radeon HD 6870M的ATI Mobility Radeon HD 6870是一个高端的DirectX 11的图形卡的笔记本电脑的AMD。它本质上是一个稍微慢的核心时钟速率的ATI Mobility Radeon HD 5870。因此,性能和功能(如UVD2和Eyefinity [宽域)是类似的老卡。是由两个64位宽的控制器,一个128位内存总线,可访问多达1024 MB或512 MB GDDR5和GDDR3记忆体的,分别存储器接口的流动性6870。 (G)DDR3使用的笔记本电脑供应商的6870M的性能受到明显。 HD 6870M提供800的MADD核心(流处理器)都集中在160 5维。的核心支持DirectX 11的硬件功能(Tessellation(曲面细分),OIT,后处理,阴影,HDR纹理压缩)。此外,16个ROPs,40TMUs,和40 TAUS都可以在芯片上被发现。约1040万个晶体管的GPU提供了理论计算能力高达1.08 TFLOPS(相比1.12 TFLOPS的5870M)。对于一般的计算,可以访问使用的图形核心ATI流的OpenCL或DirectCompute的11。的GPU的游戏性能应该是相似的HD 5870,因此足以满足目前所有的游戏(2010)高分辨率和高细节的设置(除地铁2033和孤岛危机)。详细的游戏测试可以发现上HD 5870页。的Mobility Radeon HD 6800M系列包括旧的视频处理器,UVD2高清视频解码的显卡。它仅支持VC-1,H.264,MPEG-2,DivX和其他的变体,如支持新的UVD3的6900M系列。开始用Flash 10.1,6800M系列也已经能够加快闪存高清视频(如YouTube),这最终需要的工作量的CPU。 5870,6870M是能够传输高清音频格式(如杜比True HD和DTS HD Master音频),最多8个频道和192 kHz / 24位HDMI 1.3a的。 6870M仍然只支持原来的Eyefinity技术(而不是改进的Eyefinity +)连接最多6台显示器的图形芯片。当然,同时连接6台显示器的能力将取决于笔记本电脑的供应商和供应DisplayPorts。由于高功耗的Mobility Radeon HD 6870M,它通​​常只适合大笔记本电脑(也可能是响亮的)具有良好的冷却解决方案。台式机显卡相比,应该执行的Mobility Radeon HD 6870M之间的某个地方了Radeon HD 5750和5770,至少有根据的规格。
