@All
power managment Is that for everyone else they're the same as for me : does not matter what kind of the power management you set in the power:prefs for your card, the fans on the GFX card do have the same low speed ?
What I mean, is: if we set “low power” the speed of fan is the same. If we set “Dynamic”, then the speed of fan the same. And if we set “High power” the speed of fan the same.
Between different settings, I can see the differences in the game's by FPS counter, there are indeed a bit of differences between low and high settings.
What worry me most, is that between any settings and does not matter of how i stress it, the GFX's card fans always of the same speed. Even if i touch the card, and i feel that it hot enough, the fans of the card still the same on the same speed.
For me, it didn't look like normal thing, because as far as i remember, on the other computers (PC i mean), the bigger your power settings, the more you stress the card, the faster fans are working , so to cold the card.
Of course, maybe today's card should be that "hot" , i do not know, but i not sure we with AmigaOS stress it that much so it should be _that_ hot.
That happens on all hardwares (at least on x5000 and on sam460 for sure). For sam460 i even noticed that when i boot, and GFX card's initialized, it for a second boost the speed of GFX card's fan, and then dump it to the pretty low speed. And does not matter what you do after, the speed of Fan always remain the same. Even if card is start to be more hot, and if it stressed by some shaders based stuff.
I think, that because of that, i found that RX560 i have in the X5000 for a few years, a bit “over hot”, and x5000 start to shut-downs when i load up it with a little heavy 3d games. Then once i replace it with other RadeonRX570, those issues gone, but, the new card even more over-hot in compassion of how it was with RadeonRX560.
Isn't GFX cards Fans should be spinning much faster, when GFX card is real hot ?
the speed of different cards I do have 2 GFX cards which i swap for tests in my x5000 from time to time:
The first one:
Saphire Pulse RadeonRX 560 2GBThe second one:
RadeonRX 570 ARMOR 8GBNow, the 560 one have one cooler, wasn't _THAT_ hot in default state, so i use it for a few years until it starting acts now.
The 570 one, have 2 coolers, and _THAT_ hot by default, and continue to be more hot while you do nothing. Like, the default speed on the GFX Fans is always the same, and didn't work as expected. At least that my IMHO for now, maybe that the same on PC, didn't test it here.
But then, if take into account hardware specs, then 570 one is surely faster than 560 one, but in real live test, it just absolutely the same in all games i tries. Like there is some other kind of barrier which didn't use full power of GFX cards (and maybe because of that the fans on cards didn't raise up the speed?)
What I mean, that currently, for OS4 and current 2d/3d drivers, there are no reasons to buy a “monsters” which are over hot and have lots of power. In the end of all 560 and 570 acts exactly the same, but 560 smaller, need less power, and not that hot on the run as 570 are.
I do not know how different it will be with 580 one (probably the one i will buy next for tests), but for now can say that 570 don't beat 560 on os4 currently, speed the same, but give more issue only
