Hello guys,

I would like to know what difference exists between an acceleartor board with '030@50MHZ and another with '040@50MHZ.

Please let me know

[amigakit]

An 040 50Mhz is around 3.8 times faster than an 030/50Mhz

[bloodline]

030 @ 50Mhz = ~9MIPS
040 @ 50Mhz = ~40MIPS

[TjLaZer]

Yes about 4 times. It is also a lot hotter of a chip. The only way to have an Amiga with a 040@50MHz is with the Sonnet Quad Doubler board. Not recommended. Just get a 060@50Mhz. About two times faster!

To clarify: The 060 is about 2 times faster than the 040 at the same clock speed...

MIPS is not accurate measurement of processor speed. It's actually far from being 4x as fast.

[AMC258]

I may be totally wrong here, but I seem to recall the 040 is more like 1.2x as fast. And, I seem to remember the 060 being more than 2x as fast as the 040.

As far as I remember, there is no 040@50MHz in any Amiga accelerator.

The maximum clock is always 40MHz (42 in overclocked models).

I thought that MIPS for the Amiga were a more accurate measurement of speed? What was your reasoning? I guess it depends on what we are benchmarking, but I always found it to be about right in terms of how applications perform. The only reasons I wouldn't opt for the 040 are heating and price, so price to performance the 030 would probably be a better buy given the extortionate ebay prices on 040s, if you manage to land one.

[Piru]

MIPS only works (is accurate) when comparing same processors against each other. 030 vs another 030, 040 vs another 040, 060 vs another 060.

But then it's equally sensible to just compare the clockrate and forget about the MIPS.

If you want to compare different processors use SPECint and SPECfp, or so.

060.....
Kind of hard to find these days.

[LaserBack]

if anyone here believe that the 060 is 2 times faster than a 040 is because never had both cpus to compare

I had an apollo 1240/40 then I replaced by the apollo 1260/50...then I returned to the 040 because the 060 isn't compatible with anything old

I calculate 1.2x faster

The speed betewen both cpus is not noticeable on workbench and not noticeable on most applications or games...

for example...quake on a 040 about 14 fps...on a 060 maybe 15 fps

alien breed 3d 2 ...on a 040 18fps...on a 060 19fps

The 2x times faster comparison was done years ago on magazines..it was a lie for marketing purpose

anyways that comparison was made betewen the 040/25 and the 060/50

Apples and oranges. Always good for a technical review.

These are quite bad CPU benchmarks, the CPU can't make rest of the system faster.

[LaserBack]

yes they are bad cpu benchmarks

but that's the real-life diference I think
