What is the real power of Akiko chip in cd32 ?

[steveuk]

The Mighty power of the Akiko?
Is this for real?
A stock cd32 (2mb chip+akiko) is nearly on par performance with an 030 50mhz with fast ram??
Am reading this wrong! It seems extremely impressive?

68020/14+akiko - 24.2 ms
68030/50+fast - 21.7 ms

If this is the case, and knowing the Doom runs ok on a 030/50...
If Commodore was doing well with CD32 and be financially sound back in 1994 makes me wonder... Could of Doom be ported to CD32 when the Jaguar/32X and 3DO games were being made...
By the looks of that, even the 2mb chip CD32 stock system could of had Doom.
Could we even of had a decent CD32 version of Streetfighter 2?

68040/25+fast - 18.6 ms
68020/14+fast+akiko - 17.6 ms

Although after reading this i am concerned i have read this wrong as 68020/14+fast+akiko could no way compete with 68040/25? Forgive me if i have got this wrong.

Played Gloom Deluxe tonight on stock CD32. Pixel width 1 / Pixel height 2;
ran well in nearly full screen. Impressive.

Yep I agree but I think Wolfy is possible

Hi Nova
I have been following this thread and wondered why Doom was extremely playable on Jaguar as that was only 2MB. I know Jag had 26mhz processor and CD32 14mhz - however i have played Doom Attack on CD32+4mb and it plays ok.

I am of course not a programmer or developer so my knowledge is limited - is it because it was developed by John Romero himself especially for Jaguar? Could a hacked down version by do-able on CD32 even if it has less colours or stripped down Graphics?

Would you be willing of having a crack at this if i paid you for it?

Thanks
Steve
ps> Wolf being made i believe at the moment on Jag by the same guy that did catacomb 3d.

does any talented amiga dev fancy making a CD32 (with fast) version of doom (either 4mb fast/8mb fast dont mind) ... that has CD Audio (eg. Doom 3DO music) optimised best possible for CD32/akkiko?

Happy to fund this project.

Hi Pat
I did mean CD32 14mhz + Fast Ram.
eg. so it would be bootable if you had the SX1 upgrade attached, for example.

If you follow the thread back to the start; the results show the CD32 is approx same speed for Doom as 030/28mhz with Akiko Optimised.

Doom Attack:
Amiga CD32 68020/14Mhz 8Mb (Akiko Optimised C2P) - 12872 realtics (5.8 fps)
Amiga A1200 030/28Mhz 64Mb (Blitter 020 C2P) - 12727 realtics (5.8 fps)

and/or
Gloom:
68030/50+fast - 21.7 ms
68040/25+fast - 18.6 ms
68020/14+fast+akiko - 17.6 ms

This will mean Doom would be playable (on low res/windowed) and IMO would be well worth doing.
