lame benchmarks (pun intended)

[Piru]

Doesn't mean much. I also have some stuff which have altivec insturctions inside, but still, that piece of code unused in the necessary place. In the readme to that archive a lot to say about mess with altivec, so it can be not suprise that its just broken, disabled and not works.

Did you read the readme? Here's the relevant part highlighted by me:

Unfortunately the people who tested the Altivec version for me did not have
any success, and therefore this upload only includes a generic PPC version
of 3.98.4, and Stephan Rupprecht's prior 3.98.2 G4 build.

The archive has 3 lame binaries:

Code: [Select]

[generic]               197665  411156  48.1% -lh5- 3de4 Oct  6  2010 lame-398-4/bin/lame
[generic]                50969  168764  30.2% -lh5- 9a1e Oct  6  2010 lame-398-4/bin/lame-shared
[generic]               322281  710768  45.3% -lh5- 2952 Sep 26  2008 lame-398-4/bin/lame.g4-3.98.2
The first two are the non-altivec builds (one static and the other using SObjs/libmp3lame.so).

The third is the old (26-sep-2008) - altivec enabled - build by Stephan Rupprecht, included as-is.

The same is confirmed here as well:

In any case, no-one loses anything. 3.98.4 for generic PPC, new libmp3lame which was always generic, and the prior 3.98.2 for altivec is in here. Win-win.

I realise it's a bit off topic

at least on blender test my i7 rig fits the expectations 00:39.26. so that might be a more dependable benchmark-

How is it with one thread?

[wawrzon]

is there a way to influence it?

I seem to recall an option in the render settings somewhere for the number of threads, which seemed to be set to 4 on my quad core. Probably be 8 on yours if it is counting logical cores.

@Piru

I tryed all the lame versions on hte archive from OS4Depot and get:

for Lame-G4 : 23 secs

for lame/lameSHARED : 40 secs

So the lame G4 that was 3.98.2 intead of 3.98.4 of the other 2 compiles seems to have AltiVec enabled...
Now have to see wich version was used on X1000...

EDIT:

I tryed the lame vmx from aminet under MOS 2.7 on my Peg2@1131 and GOT:

Indeed. Now, would Hans_ & kas1e please figure this thing out already? OS4 *does* have altivec enabled lame.

[Tuxedo]

@Piru

the problem was only if the X1000 test author have used the G4 version...

Why else would he claim he did use the altivec version?

ah, didnt knoew one needs to set it manually within the app like on on lightwave. another thing amiga has introduced in advance. lol. so may previous result was with one thread since this is default, with 8 i get the picture done in 00:08.80

I heard you the first time when you pointed out that the old g4 version was in the archive (which I completely overlooked).

In the meantime I got tired of waiting, so here are my A1-X1000 lame results for aksack.wav:

[haywirepc]

Where can I find a windows binary of this lame encoder? Looked but only found source tarballs. I'd like to run this test on a windows and linux machine and see the results and how they stack up against x1000 on quad core and 6 core intel machines.

Right here brah:
http://lame.sourceforge.net/links.php#Windows

No command line. There's a couple there that appear to be lame with a GUI frontend, but all the rest incorporate lame as programmatic interface and seem to use lame as just one step in their processing.
