Is there any form of real life application we can benchmark and see for example fps difference in a game or somthing?


The only way to get an accurate result for that would be on two otherwise identical systems (even better, the same system, just swap the boards) - since even things like what version you a math library a person is running might be enough to throw off the results.
Amiga 500: 2MB Chip|16MB Fast|30MHz 68030+68882|3.9|Indivision ECS|GVP A500HD+|Mechware card reader + 8GB CF|Cocolino|SCSI DVD-RAM

for the moment, i can only post some screenshots with sysspeed and bustest with my Mk3 at 75 (74,3 Mhz wichamiga say) , set to 60ns for ram in firmware.

[ATTACH]5778[/ATTACH]
[ATTACH]5779[/ATTACH]

i don't have screenshots with Mk2. and as it run at 100 Mhz too, it won't be useful...

but finding somone else with a OC'ed Mk2 running 1/1 bus to compare is doable i think... HammerD can you help ? :D


Well I have mine at 60Mhz now 1:1....I tried 66Mhz 1:1 but it's not entirely stable with my system (which has a Sonnet PPC in it) at 66Mhz....maybe it's the Mediator acting up at 66MHz, or my RAM.  I don't know, but 60MHz is ok.  I can post SysSpeed results...

BTW I have the latest mask 060 from Stan in Poland.  And my board is a MK-II 040 upgraded to 060....

yes,  doom is a real exemple. i can do a little video later today.
and i think quake have a benchmark mode too.

I would not bottleneck RAM to get a few more arbitrary MIPS. Waste of time!

Did a quick video and just let the demo run a bit.
Dont know what map you got on your video so i just used the default.

i did a quick shot with the same version as your : https://www.youtube.com/watch?v=o78ac89CHPQ&feature=youtu.be

just simply look at the first screen : i got 32 fps, where you get 17.

Yes, your fps sure is higher then what I'm getting.

believe me or not, but if you roll back your mk2 to 72 Mhz, you'll have same results.
i'm gonna do this on mine. 100 Mhz with a bottlenecked bus not really worth it...

There are a lot of different variables here.  One system has CS-MK3 that has much faster memory than a CS-MK2.  But it could very well be that Doom really needs fast system RAM above everything else.  Not sure whether Prometheus beats a Cybervision, by the way which Cybervision is that, 64 or 3d?

Ohh yes that is correct, the mk3 have a 64bit memory access :)

64 bits memory doesn't do very much in this case.
in this case, this is not specially doom. and this is not specially graphic card too.
this is simply the effect of the 060 wasting ton of clock cycles to read/write in memory when the bus is divided by 2... it's not very hard to understand.

it's a bit like if you get a car engine from 72 to 100 HP, but divided the gas pedal run by half. (i don't know if "run" is the good word in this context but english is not my native language)

look : here is my Mk2 at 66 Mhz 1:1 bus : https://www.youtube.com/watch?v=nPKMsKGj_1g

compare here at 100 Mhz : https://youtu.be/9zCHGWytf9Q?t=73

what do you see ? and please watch carefully :)

i have a very little bit better framerate at 66 Mhz... why ?
because at 66 Mhz, the bus is synchronous, and the 060 despite the fact there's less raw mips... waste a lot less clock cycles to access memory.

The first sentence you wrote in that post made me ignore everything else you have said.

If a 64bit memory access would not matter "that much" your MKII would recive the same FPS as your MKIII did, sure you had a 9Mhz differnce but that would not drop you from a stabel 25-30 fps on the MKIII to a 16-19fps on the MKII

And then we take a look at the video where MKII 66mhz vs MKII 100Mhz
Here we can see maby 1-2 fps difference in some areas at most, its very hard to tell them a part.
So if you where running a application that where not that memory hungry like Doom and would use the CPU more the 100mhz MKII would win by a long shot.

Run a timedemo and you will have a easier way to see the FPS difference.
