现在都压X264了吧,还要DIVX?
x264 HD Video Encoding PerformanceGraysky's x264 HD test uses the publicly available x264 codec (open source alternative to H.264) to encode a 4Mbps 720p MPEG-2 source. The focus here is on quality rather than speed, thus the benchmark uses a 2-pass encode and reports the average frame rate in each pass.
The latest version of the x264 codec fixes the problem exemplified in our first pass results, but these are still interesting to look at. Because of a number of unaligned memory loads all of Intel's pre-Nehalem Core based processors are penalized. The result is both the Athlon II and Phenom II are ahead of the E6300 here.
In the second pass of the test however, things return to "normal". The E6300 is technically in between the two new AMD dual-core chips, but all three basically perform the same. The Phenom II X3 710 adds another 40% to the processor cost and yields an extra ~20% in performance.
顺便改下标题,游戏性能,呵呵 |
