@Atarieterno: I can understand your ressentiment, and several other Atari-users might feel this too. You probably feel like the atari-forum had been hijacked by MiST users, including Amiga admirers. Well, in a way, it sometimes looks like there are more new messages about MiST (and MiSTer) than about Atari releases.

But on the other hand, many people, including me, are getting exposed to Atari news while they were checking the forum. So it's all the benefit for the Atari community. I am on several retro computing forums (C64, Spectrum, Amstrad), but it's the atari-forum I visit the most.

About the original topic, I own a MiST and a raspberry pi, and I find it more pleasant to play (amiga) games on the MiST than on a computer through emulation. But I'll have a look at the Amibian distribution anyway!

Ok, so going back on topic, this is the information I get from SysInfo on my MiST:

12.9x the speed of a A600
5.6x the speed of a A1200
1.47x the speed of a A3000
0.37x the speed of a A4000

So Sorgelig is right, nowhere near an A4000, but faster than any other Amiga.

In this older video, he's getting over 12 MIPS. Not questioning your results, just curious about the actual performance. Maybe it depends on which settings you use, too? Or was there a regression in terms of CPU speed in exchange for compatibility?

Wow... that is a huge gap in performance (almost 2x).

I would be interested in seeing the results from some of the other users (to see if I am doing something wrong).

Would the rest of the community care to share?

Thanks

I tried to run Sysinfo on my MiST just now, for some reason my display is corrupting when ever I try to run Sysinfo. I have a MiST and a FPGA Arcade board and I believe the Mist was a little bit fasterthan the FPGA Arcade board the last time I compared them, my FPGA Arcade score just now is 10915 Drystones and 11.39 Mips.

I just updated my MiST to the latest firmware and Minimig aga core, no more corrupted graphics but it looks like it is running slower now.
I got 6919 Drystones and 7.22 Mips, my previous core was from 2015 and it was faster than my FPGA Arcade.


I tried 3 different older cores and all of them are giving me the corrupted video display when I run Sysinfo, it used to work so I am not sure what is happening, the workbench screen displays fine.

Well I finally got my MIST board so I was also able to test for myself.

I tested all of the cores from Somuchguru. The only build that performed notably faster is minimig-mist-1_0-newcpu which gave me those 12.5 MIPS, but it has corrupted graphics and is known for compatibility issues. The others are roughly the same at just over 7 MIPS.

In the end, compatibility is of course more important than raw performance (it's easy to have great performance when the accuracy isn't as great so comparisons with 1.0 aren't 100% fair), and in most cases it's still more than fast enough. Of course if more performance can be extracted without impacting compatibility/accuracy, that's always nice too.

I am fine with the speed of the MiST Amiga core, I have an Amiga 2000 with an 040 accelerator if my MiST or FPGA Arcade is not fast enough, the best thing about the MiST is it runs lots of different cores. I am still waiting for an Atari core on the FPGA Arcade. I think the MiST is the best option right now if you only want one device. The MiSTer project might make me change my mind when I finally try one out.

Just thought I mention the latest A4000 motherboard, the Amiga A4000cr Rev D, which came only with a 25MHz 68EC030 soldered onto the motherboard, no MMU and just solder pads for a 68882.

The MiST is actually faster than that.

Yeah, only a few late 90's 3D games will give you problems on the MIST (and some 3D software etc. that needs FPU), but those games didn't run great on real Amigas either unless you had a 68040 or ideally a 68060 @ 50+ MHz. My A1200 had a 68030 @ 40 MHz, slightly faster than the MIST (with a recent core) but still not enough for games like AB3D II.
