What is the real power of Akiko chip in cd32 ?

[Cammy]

Has anyone ever tried running benchmark tests to compare the performance? I HAVE!

I have here an A1200 with an 8MB/FPU card, an A1200 with 32MB/030/FPU, and a CD32 with SX32 and 8MB/FPU. I ran the Doom benchmark test using DoomAttack, which seems to be the best DOOM port for lower-end machines. It needs more than 2MB RAM so I can't test it on an unexpanded CD32.

To run the test yourself, use this command line: DoomAttack -forcedemo -timedemo demo3

Here are the results I got:

A1200 030/50Mhz 32Mb (Optimised 020 C2P) - 8481 realtics (8.8 fps)
Amiga CD32 68020/14Mhz 8Mb (Optimised 020 C2P) - 18971 realtics (3.9 fps)
Amiga CD32 68020/14Mhz 8Mb (Optimised Akiko C2P) - 12872 realtics (5.8 fps)

So there you go, Akiko DOES work.

Here's more information about the Doom benchmark if anyone wants to give it a go: http://www.complang.tuwien.ac.at/misc/doombench.html

Hello everyone!

I have bundled DoomAttack with the better MIDI instruments file, the shareware DOOM wad, and configured it for the best settings on an A1200. Anyone is welcome to download it and give it a try, it's ready to go! If it's a little slow, run DoomAttackPrefs and disable the music by removing the text from the music plugin string, hitting Enter, and saving the prefs. I have run extensive tests on all of my Amigas and found the best results for video are the Blitter C2P (or Akiko on the CD32) and the best music plugin is the MIDI one, not the doomsound.library one. Just in case anyone was curious, here are the results I got from running the Doom Benchmark on all my Amigas:

DoomAttack

Amiga A1200 020/14Mhz 8Mb (Optimised 020 C2P) - 22976 realtics (3.3 fps)
Amiga A1200 020/14Mhz 8Mb (Blitter 020 C2P) - 20660 realtics (3.6 fps)
Amiga CD32 68020/14Mhz 8Mb (Optimised 020 C2P) - 18971 realtics (3.9 fps)
Amiga CD32 68020/14Mhz 8Mb (Akiko Optimised C2P) - 12872 realtics (5.8 fps)
Amiga A1200 030/28Mhz 64Mb (Optimised 020 C2P) - 17732 realtics (4.2 fps)
Amiga A1200 030/28Mhz 64Mb (Blitter 020 C2P) - 12727 realtics (5.8 fps)
Amiga A1200 030/50Mhz 128Mb (Optimised 020 C2P) - 8696 realtics (8.6 fps)
Amiga A1200 030/50Mhz 128Mb (Blitter 020 C2P) - 8296 realtics (9.0 fps)

ADoom

Amiga A1200 020/14Mhz 8Mb (AGA 68020 C2P) - 22984 realtics (3.2 fps)
Amiga A600 030/30Mhz 64Mb (EHB 68030 C2P) - 17886 realtics (4.2 fps)
Amiga CD32 68020/14Mhz 8Mb (AGA 68020 C2P) - 16294 realtics (4.6 fps)
Amiga A1200 030/28Mhz 64Mb (AGA 68030 C2P) - 14430 realtics (5.2 fps)
Amiga A1200 030/50Mhz 128Mb (AGA 68030 C2P) - 9133 realtics (8.2 fps)

Remember, these results are running the game in High Detail mode, in almost full-screen. The game will run faster in Low Detail mode in a smaller sized screen of course. Leaving the music on also makes a considerable performance hit so I turn it off during benchmark tests, since a PC wouldn't be using extra CPU to emulate Midi either so it's not fair on the Amiga to leave it on when testing the speed of the game engine. Anyway, here it is: Amiga Doom (DoomAttack)

I'm really sorry, everyone! I checked the archive on the FTP and it was incomplete, I guess it never finished uploading the first time. I have re-uploaded it and checked that it's the right size now, so if anyone would like to try and re-download it, it should work fine now.

I'm very sorry for linking to a bad archive.

Please try again, I've re-uploaded it from my Amiga just to be sure, and then re-downloaded and extracted it.
