Special Super Denise in A3000?

[tone007]

An Amiga 2000 with an 030/25 is faster then an Amiga 3000 with an 030/25.

I could believe this if you're only using the 2MB or 4MB of RAM on your 2630.  Once you fill that up and move into ZII memory boards, I can't imagine the 2000 still winning.

(unless of course you've got the super rare memory addon for the 2630, in which case you should sell the whole setup and buy a 3000 or 4000. )

WRONG! Do your homework, I have.
 
The Amiga 2000's bus is 24 bits wide, not 16 bits (I can not remember where I read this, but it stuck in my brain because I thaught it was odd).
 

you gotta do your homework again it seems. 68000's address space is 24 bit long, 16 bit wide. here's a resource to help you :

check a500-a2000 technical reference manuals. bus width is clearly stated there.

An Amiga 2000 with an 030/25 is faster then an Amiga 3000 with an 030/25.

Complete BS.

An '030/25 is always the same speed - 25 MHz. Throughput may vary due to RAM speed limitations - while the A3k's mobo RAM isn't lightning fast, SC ZIPs are definitely faster than an A2630's RAM (which doesn't burst).
Additionally, ChipRAM access on the A3k is 32 bit (twice as fast) as is ROM access, so all in all the A3k should beat nearly any '030/25 card in a 2000.

You'd get better results on a 2000 equipped with an '040/25 card compared to a 3000/4000 with an A3640 - which not only is the cheapest '040 board on this planet but also the slowest due to lack of suitable RAM and having to run '030 cycles.

Unless the 2000 is mil spec'ed... :smack:
