五、功耗、温度、噪音测试

首先提一下核心工作电压，Radeon HD 6870公版与讯景超频版都是1.172V，Radeon HD 6950 2GB/1GB则都是1.100V。

空闲系统功耗

游戏负载系统功耗

拷机负载系统负载

GeForce GTX 560 Ti的待机功耗控制相当不错，与前辈并列榜首，不过游戏和拷机负载中迅速增加，比前辈高出20-40W，基本快赶上Radeon HD 6970了。

Radeon HD 6950 1GB/2GB的空闲和《Crysis》游戏功耗都差不多，但在FurMark拷机中前者低了多达12W，可能是因为1Gb GDDR5显存颗粒工作电压较低一些的缘故。

讯景Radeon HD 6870 Black Edition频率提升之后，功耗随之增加也是可以理解的，三种情况下分别多了2W、11W、16W。
