64 bit LAME compiles

hello everyone, I have slight problem to find LAME 64 bit compiles, specially actual 3.98r version.. Any suggestion?

Anyway, is there any reason why ain't 64 bit compiles stored at some common place like RaReWaReS ?
Or doesn't make it sense to compile 64 bit at all ?

thank you

Gabriel put up a 64 bit compile of (I believe) 3.98 (not the latest 3.98.2) here:
http://gabriel.mp3-tech.org/lame/x64/


And there's a bit of discussion of it here:

The reason is quite simple - the current compile is faster.  I ran a test having created a 64 bit compile and it actually ran marginally slower so it seemed somewhat pointless to make it available.

John, this is exactly what I expected  Is it possible to make 64 bit compiles available for those who are interested anyway ?

You can get 64-bit LAME compiles at http://lame.bakerweb.biz/. They are built with Visual C++ 2008, but the 64-bit build is about 25% faster than the 32-bit build (even though the 32-bit build uses assembly).

Thank you, joebob90, for making the 64-bit LAME compile available.

Unfortunately, I'm not seeing that this 64-bit compile is faster than the 32-bit compile available at RareWares. I tested on a CD-image WAV file produced by EAC. In my first set of tests, the only LAME option I used was -V2. I did three runs where I ran the 64-bit LAME EXE followed by the 32-bit LAME EXE:

In my six test runs, the 64-bit LAME EXE finished faster only once and by just a fraction of a second. All the other runs showed that the 32-bit LAME EXE was a few seconds faster. I didn't run anything else while running these timing tests. I am running Vista Home Premium 64-bit with SP1. I have an Intel Core2 Duo CPU P8400 @ 2.26GHz with 4 GB RAM.

Is there another option I need to specify to make the 64-bit EXE run faster?

By the way, the 64-bit LAME EXE announces itself the same as the 32-bit EXE:
LAME 32bits version 3.98.2

To my knowledge, there really isn't anything that can be done.  As john33 said, the 32-bit compile of Lame runs faster than the 64-bit version.  Your results supported this and fell in line with john33's tests.  So just use the 32-bit build since the 64-bit build doesn't offer any benefits.

64-bit is only faster for applications that use really large numbers (larger than 2^32). On a 32-bit system such numbers need to be represented in memory with multiple addresses, and doing math on them is rather slow. On 64-bit systems they can be stored in a single location and math can be done on them natively by the processor.

In LAME's case, there's no real benefit. 64-bit isn't magically faster.

joebob90 said his 64-bit build is about 25% faster than a 32-bit build (his own 32-bit build?). How did he get it to run about 25% faster?

He got it to run 25% faster than his 32-bit build, but not john33's 32-bit build, I'm guessing. Trust john33. He knows what he's doing.

Gabriel said earlier that he got his 64-bit LAME 3.98 encoder to run 20% faster than his 32-bit compile (both using the VC8 compiler). He even said his 64-bit encoder is the one he uses most of the time:

[a href='index.php?act=findpost&pid=452988']http://www.hydrogenaudio.org/forums/index.php?showtopic=50578&view=findpost&p=452988[/a]

So Gabriel's results were similar to joebob90's 25%.

True, but Gabriel doesn't use the Intel compiler.

BTW, adding "/arch:SSE /fp:fast" to LAME options increases speed of MSVC8 compiled executables.

You don't use the Intel compiler for producing 64bit output either.   
Am I wrong?

I think the latest versions of the Intel compiler (>= 10.1.020) support 64bit code.

I finally got around to producing and testing 64 bit Intel 11.0 compiles.

The fastest of them is around 10% faster, in my testing, than the current Win32 compile on Rarewares. 

Currently, this is a 3.99.a1 compile of the .exe only and you download it here: http://www.rarewares.org/files/mp3/lame3.99.a1-64.zip

If there is interest, I can produce a similar compile for 3.98.2.

Well, that's kind of bizarre!! The comparable 64 bit compile of 3.98.2 is about 7% slower than the compile currently on Rarewares! Still want it?

I don't see the use of this discussion, unless the code is specifically programmed to take advantage of larger registers etc, there is no reason that the 64 compile would run faster than the 32 bit compile... Don't forget that the only difference in the way numbers are treated in the Win64 model is that pointers are twice the width (as compared to 32 bit)... So without taking any other effects (like is the compiler really the same etc...) into account, the code would run slower, due to more memory overhead... the numbers are treated is exactly the same... The only MicroShaft objective into going into 64bit was (and is) to enable addressing of memory over 4GB without resorting to tricks...

Compiler can use more general-purpose registers and SSE registers with 64 bit compiles.

Sort of off-topic, but if I get a new 64-bit computer, does that mean I'll have problems running audio encoders that worked on a 32-bit system?
