一、功耗



SU2300的待机功耗是最低的,甚至比Atom 330都要低5W,OCCT Small FFT测试和高清播放的时候则与Atom 330完全持平。i3-540功耗最高没什么意外,不过其频率已经超过3GHz,性能上是对得起这种功耗级别的。
二、画质与硬解
CULV、ION这种组合的最佳应用当然是HTPC,所以画质水平非常关键。这里我们使用业界标准的HQV 2.0看看它俩能得多少分。

最终得到了108分,刚刚超过满分(210分)的一半,不算多出色。降噪和过滤的压缩残影、倍线压缩残影环节失分比较严重,不过在40寸的索尼Bravia电视上实际看不出多少差别。画质转换的对比度增强、肤色纠正环节没有得到任何分数,毕竟ION系统计算能力偏弱,NVIDIA并未在驱动程序中提供相关特性的支持。
除了画质,硬解能力也是HTPC的重要指标。播放一段50Mbps码率的MKV高清视频,CPU占用率最高仅有13%,相当完美。
