Benchmark coverage: 13%
Atom Z3770 outperforms E-450 by 856% in TrueCrypt AES.
WinRAR 4.0
WinRAR 4.0 is an outdated version of a popular file archiver. It contains an internal speed test, using 'Best' setting of RAR compression on large chunks of randomly generated data. Its results are measured in kilobytes per second.
Benchmark coverage: 13%
Atom Z3770 outperforms E-450 by 84% in WinRAR 4.0.
x264 encoding pass 1
x264 version 4.0 is a video encoding benchmark uses MPEG 4 x264 compression method to compress a sample HD (720p) video. Pass 1 is a faster variant that produces a constant bit rate output file. Its result is measured in frames per second, which means how many frames of the source video file were encoded per second.
Benchmark coverage: 13%
Atom Z3770 outperforms E-450 by 150% in x264 encoding pass 1.
x264 encoding pass 2
x264 Pass 2 is a slower variant of x264 video compression that produces a variable bit rate output file, which results in better quality since the higher bit rate is used when it is needed more. Benchmark result is still measured in frames per second.
Benchmark coverage: 13%
Atom Z3770 outperforms E-450 by 165% in x264 encoding pass 2.
