I took my old compiles and also compiled the sources with SSE4.1 instruction set. Then I took an album (57m 37s) and encoded it. Results (encoding time, in seconds):

32 bit:
SSE  - 89.5 s
SSE2 - 72.2 s
SSE3 - 73.2 s
SSE4.1 - 72.1 s

64 bit:
SSE2 - 67.1 s
SSE3 - 66.5 s
SSE4.1 - 66.1 s

BTW, I also tested original Lancer from http://homepage3.nifty.com/blacksword/index.htm

SSE  - 57.7 s
SSE2 - 53.2 s
SSE3 - 53.1 s

SSE2 MT - 35.9 s (71.6 s total process time)
SSE3 MT - 36.2 s (72.3 s total process time)

It seems that older versions (that require Intel DLLs) were faster than current. Also, SSE2_OLD version is as fast as before. (misconfigured compiler?..)

The SSE2_OLD is actually configured in the same way as the SSE2 compile. Both are ICL 12.1 compiles. The only difference is that the OLD was compiled within VS2008 and the other within VS2010.

After finally getting the 64-bit machine operational, I have some benches to add here (running i5-2600K [OC], 8GB, WinXP x64 SP2):

OggEnc 2.87 aoTuV b6.03 Lancer builds (-q 3 [126.2 kbps])
SSE2 ........ 74.13x
SSE2 old ... 98.84x
SSE3 ........ 74.13x
SSE3 x64 .. 107.83x

Ok, the results using Vorbis -q3 running on i5-2500K (OC'ed), 8GB, WinXP x64 SP2.

The encode rate and bitrate numbers come from the binaries themselves. To help make sense of which version I was running I included the binaries' date-stamps.

oggenc "02/20/2012" is based on aoTuV 5.7, not 6.03

 Fixed.

I got pretty confused with this many binaries.

(Time expired editing above post while typing...)

FYI, I noticed the SSE binary in the aoTuV b5.7 bundle (post #121) declared itself b6.03. Because the bitrate is consistent with the other compiles in the bundle I'm guessing it's just a typo.

It's worth mentioning that Vorbis doesn't have drastic bitrate variance when compiler options change. When I posted the average bitrate in the above table it really means each individual file had the same bitrate, respective of the builder+compiler.

...That's strange. Thank you for the info.

I was wondering if somebody whos got gcc could give us a compile with AVX or AVX+sse4/4.2a to test on bulldozer based chips.

apparently they fixed the AVX support with newer gcc versions http://www.primegrid.com/forum_thread.php?id=3912

would be interesting if it where possible to see how AVX would effect encode speeds if at all  (cant wait for them to also have FMA support)

thanks in advance to whoever gives us an avx build to play with

Are the AoTuV b6.03 sources from post #117 mixed with Lancer?

For decoding only, are there major quality/bugfix differences between the current libvorbis/vorbisfile and what the latest "original" Lancer was based on (from late 2006)?

Yes, but I tested only encoding part of these sources, and I'm not sure that decoding works properly.

See http://svn.xiph.org/trunk/vorbis/CHANGES  (original Lancer is based on libvorbis 1.1.2).

It seems there are decoding related changes since then. Also things like "Corrections to the specification" or "Fix a numerical instability in the edge extrapolation filter" which I don't know if are relevant or not.  So staying with an old version isn't a good idea.

How did you do the merge? Comparing Lancer against AoTuV 5, then AoTuV 5 to 6, or libvorbis (and co.) 1.1.2 to 1.3.3, and patching in  in unchanged parts?

Did you try creating new SSE code? If there are clear cases of calculations done on arrays, is it necessarily difficult?

any chance of a compile with FMA support? 

we cant get an intel compiler build with AVX support because intels compiler blocks non-intel chips from getting AVX code paths sadly, but FMA could have a beneficial effect on encode performance I would think

Ogg Vorbis acceleration project, Is it dead?

Yes. As vorbis himself. Xiph developing another codec "opus". Welcome, new abandonware. For people who support vorbis nothing remains except "thanks". Fate of many open source projects, lack of interest.

Tuning is boring? Start new project.

How about wide hardware support? I'm not sure if the opus will get it even in next 2 years. That's nonsense (to close Vorbis project). Also AFAIK Opus has more targeting onto low latency and low bitrate (of course not without a cost of quality loses for simple file encoding at medium bitrates).

1) Ogg Vorbis works very well in its current iteration;
2) Codec support these days is probably more software than "hardware".
