An around 20%+ increase in speed, nice :)
And soon GOLD3 will add AGA on top of it! Nice days to be.

|great stuff! :D|
blows normal 68k out the water!
I'm building a table of times for everything I can get my hands on classic-machine wise that can run that bench. but it's taking time as I can't fully focus on it. will post it up as and when its suitably "done"

|Just when I thought my V500 had reached it's speed limit, you guys improve it AGAIN!|
Awesome work team, can't wait for 2.11!

I won't post the results, but I find it interesting a modern CPU under POV3.7 completes the scene in under 60 seconds. How far we've come.

If Apollo can do it in 25 minutes at less than 100 MHz, a 4 GHz CPU should be able to do it in about 40 seconds even if it wasn't a more advanced architecture. I think Apollo looks pretty good in this comparison.

I would propose that we focus on comparing real 68K CPUs.
Lets try to stay on topic!

|speaking of on topic, this is what I have so far. it's all ground to a halt as all my miggys have had to have been put away except my V500. so, as it stands:-|
Model accel. cpu fpu Time (hr:min:sec)
A500 GVPA530 68030@40 68882@40 07:05:04
A1200 Bliz1230Mk4 68030@50 68882@50 05:10:27
A1200 BlizPPC040 68040@25 internal 03:30:14
A1200 Bliz1240 68040@40 internal 05:26:17 *weird!!!
A3000 stock 68030@25 68882@25 10:34:21
A3000 A3640 68040@25 internal 04:53:15
A3000 CSmk3 060 68060@50 internal 01:08:33
as we can see, the 68040 really loves a bit of local fast ram with the blizzppc040 beating the A3640 by an hour and 20 mins even though both are running the same CPU at the same speed. the only issue is no matter what I did I couldn't get the Bliz1240 to run a sub 3hr pass @40Mhz. all diag and bench programs seemed to indicate that speed and power were all correct - so I dunno what was going on here. tried all kinds of things, but couldn't change the output times.

|As a curiosity I did test it on my Linux machine with AMD cpu.... 0.65 second. Same flags. 8.6 seconds when using just single thread. Resulting image looks the same and the scene looks to be still compatible with modern povray.|
Gives you idea of technological progress.
68080 is of course impressive achievement of course for 68k core running on FPGA.

|just for the lols. I thought i'd run this on my A4k now she's up and running again, and to see if something is going on, as performance … doesn't feel right, even though all CPU benchmarks are telling me everything is right with my 040 as regards mips/mflops etc|
Model accel. cpu fpu Time (hr:min:sec)
A4000 A3640 68040@25 internal 06:18:47
ouch! beaten by a blizzard030! alright, so I guess the A3640 really doesn't like either the ram on the mainboard or the zorro ram to back it up. :D

|Very good work. |

|Has anyone ran the scene on the V4SA?|
02 Nov 2019 14:32
|Ran this fish too on Powerbook G4 and my A1200/060@64MHz. The result from the blizzard seems weird since it took 2h20m with the fpu version of Povray. |
Same 68k+fpu version on MorphOS 3.12 ran in 4m03s ! Pretty impressive! That's on 1.5GHz G4.
PPC version V3.6.1 of Povray took only 2m09s.
But damn, is my Blizzard really that slow? :)
02 Nov 2019 19:52
|i agree, your Blizzard certainly shouldn't be that slow. but it does tally up with my blizz040 being strangely slow too. i'm almost glad someone else is getting weird results - so i'm not going totally crazy.|
my 060@50 does it in an hour and ten, i'd imagine yours @64 should be about sub one hour, not nearly twice as slow.
My a4000/040 really suffers doing this with 8meg or less on the mainboard. if i put it up to 16 meg, i cut nearly 2 hours off my render time. So i'm wondering if its the ram configuration. i'm going to re-run this on my blizzard040 but with as much ram as i can on its main ram socket - not rely on the scsi-kit's simm slot because i'm lazy and its easy to get to.

|Small update. I downloaded the 060 optimized version of povray from EXTERNAL LINK |
Now i got a result of 1h 06m. Much better and more in line with other results. There's probably some room for improvement though i had some other tasks in background and it wasn't right after a reboot.
Ok. As little as possible in the startup and background and the time is now 58min 5sec.
