MeGUI CPU Time Test - Compare different CPUs encoding the same file
I am interested in seeing how newer CPUs compare to my old Athlon XP 3200+. To participate in the test, just download the test file and follow the "instructions.txt" file that's included in the rar file and just post your results to this thread. I'll compile them and post them collectively here.
The rar file contains a small (43 meg) mpeg-2 clip with the an avs script file, d2v file, the jobs etc. test files and avisynth plugins if you need them (edit - links removed due to inactivity, if you want them, make a post in the thread and I'll add them back) Remember to read the instructions.txt in the rar file and be sure to grab the older version of x264.exe (also in the instructions.txt). UPDATE:The results to-date were using a pretty aggressive avs file. I have since updated the files and made a new test.rar -- if you participated in the test PLEASE DELETE YOUR C:\WORK AND WORK.RAR and download the new one from the same URL which uses a more realistic avs file. The new test doesn't require you to mess with the threads setting at all - it is automatic for everyone. I'll start populating a new table with your new results. I started with my own. Thanks all! Update: 07-Apr Added new data comparing the mt.dll results from the standard results for some multicore machines. ------------------------------------- ![]() If you keep your CPU:Mem bus 1:1, you'll find that the data scales in a highly linear fashion albeit short of the theoretical maximum. Here is a little analysis on chantmak's data to this end. ![]() Here is a subset of the data showing that, at least with MeGUI doing this avs, there is really no advantage to running with a higher FSB @ the same clockrate. Mem timing does seem to have an effect (last row). Have a look for yourself: ![]() Have a look at the post by aicjofs here where he shows that using mt.dll on the work.avs I provided can translate into an addition boost of ~14 % on his QX6700. Morph166955 also got a pretty hefty boost on his octacore machine you can read about here. I compiled their results in the table below. If you want to experiment with mt.dll yourself, please post your results in the thread and I'll add them to the table as well.

I have an E6300 overclocked to 3.2GHz. Doesn't have the 4MB of L2 cache, but I get a boost from the higher memory speeds.
Post a link so everybody can download it, I'm sure you'll get some takers. I don't really want to download a ton of plugins though.... Post your AVS file and upload your clip. Mediafire.com is apparently good. |

Thanks to both of you guys. I'll put the clip and script together and hopefully later tonight get a friend to put it up on the web for you to d/l.
I have an old athlon xp and just wanted to see how much speed gain the 6600 or 6700 would offer doing an encode (2x speed gain, 4x speed gain, etc.) I'm thinking about building a new core 2 duo system to replace this one. I'll PM you guys with the link ASAP. Thanks! Last edited by graysky; 16th February 2007 at 21:10. |

Public test?
Hi Graysky,
maybe there are more people willing to test, so I would like to suggest using some public upload site like rapidshare.de (see sticky http://forum.doom9.org/showthread.php?t=96362) if you haven't considered this already. Hopefully, then you might be able to compare the results between different PCs more objectively. If you do this, it will make sense posting results like this: time - CPU - frequency - RAM - frequency - OS 36 s - E6600 - 2.4 GHz - 1 GB DDR2-800 - WinXP Pro Last edited by jeffy; 16th February 2007 at 22:29.

Thanks jeffy... I agree with you that for a serious comparison and to draw meaningful conclusions we need to be more rigerous about this. My goal here is just to see ballpark numbers to help justify the cost of a new machine right now
![]() I think for a real test like you're talking about, we'd need to do more than a 1 minute clip which is just what I got here and am about to put up on a friend's webspace. Are you interested in becoming a datapoint too? |

Very cool. Thanks for doing the test. So it's ~2x boost in encoding time. Can you comment on your overclock. How different are the settings you're using from the stock settings? Also, which MB do you have and would you recommend it?
I'm thinking about either a 6600 or 6700. I also read about the planned cuts, thanks for the link. The other thing I'm thinking pretty hard about is waiting for the 6650 and 6750 to get released and run one on the newer chipset... decisions decisions! Thanks.

Additional info

RAM 587 MHz vs. 533 MHz stock Regarding the motherboard: ASUS P5W DH Deluxe, http://www.asus.com/products.aspx?l1...98&modelmenu=1 I used Noctua NH-U12F for CPU cooling http://www.noctua.at/main.php?show=p...ts_id=6&lng=en I had some issues with this board, but unfortunately it proved that I had my RAM modules faulty so I had to RMA them (running with replacements now), therefore I am unable to comment on its stability. |

Some more tests
Well, I have to admit something happened the first time... the filesize is too LOW
So in the end I have decided to make the overclocked high priority comparison again. I have forgotten to make a note about filesize in some cases, sorry. I have also tried changing the priority in job1-2.xml and job1-3.xml from IDLE to HIGH and NbThreads from 1 to 2, 3 and 4. Stock, idle: ![]() Stock, high: ![]() Overclocked, high, take 2: ![]() Overclocked, high, 2 threads: ![]() Overclocked, high, 3 threads: ![]() Overclocked, high, 4 threads: ![]() Final comparison table:

ftp://ftp6.nero.com/tools/NeroDigitalAudio.zip Just put neroAacEnc.exe in your MeGUI dir (not the /tools) and it should work. |
