Athlon 300U outperforms E-450 by 332% in Cinebench 10 32-bit multi-core.
wPrime 32
wPrime 32M is a math multi-thread processor test, which calculates square roots of first 32 million integer numbers. Its result is measured in seconds, so that the less is benchmark result, the faster the processor.
Benchmark coverage: 18%
E-450 outperforms Athlon 300U by 318% in wPrime 32.
TrueCrypt AES
TrueCrypt is a discontinued piece of software that was widely used for on-the-fly-encryption of disk partitions, now superseded by VeraCrypt. It contains several embedded performance tests, one of them being TrueCrypt AES, which measures data encryption speed using AES algorithm. Result is encryption speed in gigabytes per second.
Benchmark coverage: 13%
Athlon 300U outperforms E-450 by 2011% 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WinRAR 4.0 is an outdated version of a popular file archiver.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%
Athlon 300U outperforms E-450 by 232% in WinRAR 4.0.
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%
Athlon 300U outperforms E-450 by 540% in x264 encoding pass 2.
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%
Athlon 300U outperforms E-450 by 448% in x264 encoding pass 1.
