没有做过比较 不过gentoo官方论坛商 比较过 - Program Benchmark 32-bit/64-bit
- == Faster when 64-bit ==
- boot same kernel, services 22s/20s
- *compile Firefox 1382s/916s
- *compile xorg-x11 1812s/1298s
- hdparm hdparm -Tt 1192 MB/s, 55.8Mb/s vs 1250MB/s, 55.8MB/s
- bzip2-1.0.2 bzip an avi file 69.3s/60.3s
- java bitwise ops on longs 39s/12s
- java bitwise ops on ints 49s/19s
- oggenc-1.0.1 encode song 17.5s/13.3s
- PAN circuit simulator see post #4 2-5% faster
- POVRay render scene 1624s/1335s
- == No appreciable difference ==
- gzip-1.3.3 gzip an avi file 9.2s/9.2s
- == Faster when 32-bit ==
- *compile kernel 246s/254s
- lame encode 276s/294s
- mencoder-1.0pre4.3.3.4 transcode/ffmpeg ~160fps/~80fps
- mplayer-1.0pre4-3.3.4 -benchmark/ffmpeg 18.3s/26.2s
- xvid encode 984s/>2400s
- * Note that compilation tests are not comparisons of processing power, since
- compiles were with different flags and for different architectures!
复制代码 也没有快特别多
硬件支持 编译内核应该就可以搞定 |
