Title: A question about IBrowse
Post by: melott on January 15, 2005, 04:37:14 PM

I use IBrowse on both my A2500 and my A3000.

I think IBrowse is actually faster on the A2500
than on the A3000

My A3000 .....
WarpEngine 040 @ 40mhz
CV64 gfx
80 megs ram

My A2500 ....
GVP TekMagic 060 @ 50mhz
DKB MagaChip (2 megs chip)
Scan doubler FlickerFixer
128 megs ram

I'm just wondering why IBrowse seems faster on
the A2500.
I would think the A3000 would be faster at 40 mhz
on the 32 bit bus than the A2500 at 50 mhz on a 16
bit bus.

Also I've heard that IB is being upgraded to ver 2.4.
Anyone know anything about that??

You're comparing 68040 and 68060. 68060 is more than twice as fast as 68040 at the same clock.

Also the TekMagic's bus to memory (situated on the board itself) is 32bit.

The only bottleneck on the A2000 are the chipmem writes, and apparently that isn't slowing it down as much as you'd imagine.

Hmmm...

I hadn't really realized the 060 was that much faster.

It would be nice to a ColdFire cpu under the hood.

Perhaps...

However, I would advise everyone to wait until some impartial 3rd party has reviewed the ColdFire hardware. Elbox has been known to use misleading marketing before (Making big deal about Mediator pci<->pci speed which is mostly irrelevant, talking about megabits and not megabytes etc). I wouldn't be too surprised if the average performance of the ColdFire accelerator would be much worse than advertised.

Also showing the actual "Dragon" hardware running would certainly help proving it exists and works, considering the SharkPPC is still to be demoed running anything.

IMO you should stick with the real m68k for now.

@Piru

Yes you are right.....
Its a waiting game.

I was kind of thinking of Oli  H-D's ColdFire project.
But I haven't seen anything from him in quite awhile.
Maybe it was too much to hope for.......

Yes, still 68k, a lot of bug fixes and Flash support (i'd read somewhere).
3.0 will be OS4 native finally.
