我們很驚訝地看到新mini某些測試中打敗了dual 2GHz G5,而在其他測試中的表現也很接近,甚至在XBench OpenGL圖形測試中輕松擊敗Quad G5。Intel core duo處理器果然威力驚人。
CPU占用減半 PowerDVD H.264新解碼包下月推出 - 2006-3-8 14:39:00 ZNXF | H.264被視為MPEG-2壓縮算法的最佳繼任者,但目前流暢解碼H.264視頻對硬件配置的要求還很高。以推出PowerDVD而聞名的Cyberlink公司宣布將在下個月發布新的PowerDVD MPEG-4 AVC Pack,并承諾提供更優秀的H.264解碼加速能力。該公司還特別指出,在某些采用nVIDIA GPU的系統上,新解碼包最多可以令CPU占用降低50%。
H.264編碼又稱為MPEG-4 Part 10或AVC,是一種高清晰節目的高效壓縮方式。蘋果Quicktime網站上的H.264片斷累計已經被下載了數百萬次。這種編碼方式同樣將應用在未來的HD DVD和藍光DVD電影中。
Cyberlink的新版PowerDVD解碼包將在4月份推出。
