Amithlon Benchmarks

In the following, I have compiled the results for a range of easily accessible benchmarks. I hope that this may give some idea of the relative performance you can expect from an Amithlon system.

 I have not commented any of the results; I want people to be able to form their own, objective opinion. There are some "outliers" in there (i.e. values that are far away from the "usual" and "expected" outcomes). Be careful to check for the influence of such values on any averages you might look at.

 Also, I have occasionally taken the ratios of arithmetic averages; That is not really a good thing to do, but if I don't, people will complain and/or suggest a hidden motive. It is better than taking arithmetic averages of ratios, at least....

 I hope this will come in useful to someone,

This is running the Bytemark port straight from Aminet (see

   http://www.aminet.net/pub/aminet/util/moni/ByteMark68kPPC.lha

for your own copy). Running nbench.040fpu on Amithlon. The following
are the results as reported on a 1.3GHz Athlon. The comparison values were
taken from Usenet post

   <37893DA5.MD-0.198.s.giovenella@spamfree.pn.nettuno.it>

and were measured on an A3000/CSPPC with 66 MHz 060 and 233 MHz 604e.

The comparative MHz columns are not to be taken too seriously, because
performance will not actually increase linearly with CPU speed; Memory
bandwidth is also an important factor, and thus an 060 or 604e overclocked
to these frequencies would still not actually get anywhere near these
speeds.

                         %%%%%%%%%%%%%%%
                         % Speedometer %
                         %%%%%%%%%%%%%%%

This is Speedometer 4.02, running under Shapeshifter 3.10.

Screenmode is 1024x768 in 256 colours. The system this is run on is a 1.3GHz
Athlon Thunderbird, with a GeForce2 MX-200 graphics card.

Comparison values for 060/66 were taken from

    http://www.amigapro.com/Images/Speedometer.gif

Comparison values for iFusion on CSPPC 604e-200 were taken from

    http://www.blittersoft.com/speed.jpg

Once again, don't pay too much attention to the comparative MHz figures,
because even if one could overclock the 060 or 604e to these levels, one
would still be quite short of the actual performance observed under
Amithlon.
The "Disk" test was left out, because Speedometer 4.02 is faulty in
the way it reports relative disk speeds larger than 5[1]

Yes, I *know* these are not benchmarks. I know these shouldn't even be
considered for benchmarking. But of course, some people *do* use them
for benchmarking (you know who you are!), so I will provide numbers. Unless
you feel an irresistible urge to compare machines based on their RC5 or
OGR scores, you should completely ignore this section!

This one is fairly memory bandwidth sensitive, and also might thrash the
branch prediction cache on some processors.

Instructions: Download a version of Povray compiled for your processor/machine.
Amiga binaries used to be available at

    http://www.amigaworld.com/support/povamiga

I currently can't connect to that host, though.
Then issue the following commands:

    assign povray31: your_path_to_povray
    povray31:

    povray31 -i skyvase.pov +v1 +ft -x +mb25 +a0.300 +j1.000 +r3 -q9 -w640

Result:  Amithlon, 1.3GHz Athlon TB -->   104 seconds
 

                          %%%%%%%%%
                          % bzip2 %
                          %%%%%%%%%

This one is using a near-state-of-the-art file compressor. bzip2 is
a block sorting compression program, using the Burrows Wheeler Transform.
It also does a fair bit of bit fiddling when it comes to entropy-coding
the move-to-front ranks (Yes, I am a compression person. If that was all
incomprehensible to you, don't worry!).
bzip2 is available on Aminet, at

    http://www.aminet.net/pub/aminet/util/arc/bzip2.lha

That archive includes versions for 68k, the Phase5 PPC.library, and
WarpOS; Thus, it makes an ideal comparison testbed.

Once you have the appropriate version for your machine installed (read
the README! And don't forget that you might need to set a sizable stack,
or things *will* crash!), get

    http://byron.csse.monash.edu.au/forsteve/oink.bz2.bin

(which is a 150k file, bzip2'ed from 4MB). Bunzip it with any version
you like (this isn't the test yet), and then simply time how long the
following takes, using the version of bzip2 you installed:

     bzip2 -9 oink

where "oink" is the name you bunzip2'ed the downloaded file to. This might
take several minutes, especially on the 060, so don't be impatient.
This is best done in a ramdisk, so your results are not influenced by
disk I/O

Result: Amithlon 1.3GHz Athlon TB --> 34 seconds

                       %%%%%%%%%%%%%%
                       % Voxelspace %
                       %%%%%%%%%%%%%%

This is a demo that comes with the WarpOS distribution. It can use either
a 68k CPU or a PPC, if available. In both cases, it is executing hand-written
assembler code. The "Freq:" entry in the information box is a frames-per-second
counter.
Some comparison values exist, suggesting around 100fps in 320x200 on a
CSPPC/CVPPC combo. However, that resolution is so silly, it's not worth
talking about (I *do* have a 21" monitor, after all!).

Instructions: Run the "Run Voxelspace P96" or "Run Voxelspace CyberGfx"
script, whichever gives better results on your particular setup. Select
"640x480" for the first test, and "1280x1024" for the second. Leave
all other demo settings at their default values, and (without touching
the mouse or keyboard) note down the "Freq:" field. Then move around
a bit and check out the range of fps you get while in various spots,
looking into various directions (all sorts of cache issues come into play
when doing this).

Results:

 Amithlon 1.3GHz Athlon TB, GF2 MX-200,  640x480,  P96 -> 140fps (130-170fps)
 Amithlon 1.3GHz Athlon TB, GF2 MX-200, 1280x1024, P96 ->  31fps ( 20- 35fps)
 

                          %%%%%%%%%
                          % Quake %
                          %%%%%%%%%

There are many versions of this game for the Amiga. On Amithlon, we use
Quake68k by Frank Wille and Steffen Haeuser, available from

    http://www.aminet.net/pub/aminet/game/shoot/Quake68k.lha

We also have, currently just for our internal use, a version of this in
which three texture mapping routines were replaced with x86 native code.
Doing this took one day (most of which was spent on working out which
routines to target, and where to find suitable x86 replacements for
them).
Frank Wille and Steffen Haeuser's port also comes in various PPC flavours,
and you can also get a GLQuake port which, IIUC, sits on top of Warp3D.

The "standard" Quake speedtest is to go into full screen mode (no
status bar, just plain, rendered stuff) activate the console (the '~'
key will usually do that) and type

    timedemo demo2

Then deactivate the console, watch until the demo finishes, reactivate
the console, and there will be an fps number.
Apparently, Amigactive instead uses "timedemo demo1". Oh well....

Here are some results (from the usual machine)

    1024x768, pure 68k code, timedemo demo2 :  16.2fps
    1024x768, pure 68k code, timedemo demo1 :  16.7fps
     640x480, pure 68k code, timedemo demo2 :  34.1fps
     640x480, pure 68k code, timedemo demo1 :  34.4fps

    1024x768, some x86 code, timedemo demo2 :  22.2fps
    1024x768, some x86 code, timedemo demo1 :  23.8fps
     640x480, some x86 code, timedemo demo2 :  42.6fps
     640x480, some x86 code, timedemo demo1 :  44.1fps

[1] What happens is that the raw, measured value x is taken and divided
    by 1. If the result is <5, then it gets entered into the record.
    Otherwise, x is divided by two. If that makes the value <5, then
    it is used. Otherwise, division by 3, 4, 5 and so on is performed,
    until finally a value <5 is achieved.
[2] This pretty much is the same as the screen refresh rate as perceived
    by AmigaOS. Unless the value is <50, it has nothing to do with actual
    speed.

                              %%%%%%%%%%
                              % Benoit %
                              %%%%%%%%%%

This is a little fractal renderer that Phase5 included with their CSPPC
cards. It can calculate using either the PPC or the 68k CPU; As Phase5
also distributed source (although not to the binary they included....),
it is quite evident that there are close to no 68k->PPC->68k context
switches when using the PPC to calculate.

The same program is also available from Aminet at

    http://www.aminet.net/pub/aminet/biz/p5/Benoit-V2_0.lha
 

Instructions: Set your screenmode to 1024x768x24 or 1024x768x32 (this is
*very* important, because the size of the Benoit window is calculated as
1/4 the size of the current screensize. If you use different screen sizes,
you cannot compare results!).
Then start the Benoit executable; It will self-time how long it takes for
the startup fractal. You can then change the CPU settings and click
"Calculate" again, to have the same fractal rendered by your other
CPU.

Results: (usual machine)

      Startup Fractal, pure 68k code    :  0.30 seconds

We also have a version, currently for internal use only, in which we compiled
the actual calculation engine to x86 code.

      Startup Fractal, x86 calculations :  0.06 seconds

[ Note: Just recompiling the C source to 68k code with gcc reduced the
  68k time to 0.20 seconds, though, so the speedup from going gcc-compiled
  x86 is not quite as massive as it looks ]
