3DMark06 Pixel Shader 1920x1200分辨率测试功耗

成绩

排名

后两项测试试图考察显卡的最大功耗，结果最低读数来自Radeon HD 5450 GDDR3（15.1W），“最高分”HD 4870 X2居然达到了321.8W（本测试没有加入GeForce GTX 480/470是个遗憾），已经超过了PCI-E插槽（绝大多数仍为75W）+6pin（75W）+8pin（150W）的极限。不过，AMD在HD 5000系列上没有重蹈覆辙，HD 5970已经降至288.7W。另外值得注意的是，测试使用的GeForce GT 240 1GB GDDR5并没有使用外接供电，但75.6W的峰值功耗已经超过了PCI-E插槽的极限。
