The RX Vega 64 Owners Thread

Imho R9 290X/390X has this award. As is a 5 years old card, that is still there in mid range beating every new comer to learn it's place below it.
Having left behind (by miles) it's direct, and more expensive, contemporary competitors. The GTX780Ti & TitanX.

I do have an R9 290 OC Tri-X so could give a close to direct comparison. Need to get a new cooler on it though...

Unless anyone has a spare waterblock lying about for one...
 
Have been thinking of getting rid of my 1080ti for some time now.. drivers are running like **** in windows 10 and no matter who is to blame for it ive had enough of it. Would love a vega card, even if it means 20-30% less performance. Frametimes on my older 290 and even the rx 480 was great just lagged that proper punch in 1440p gaming. My problem is the prices for both new and 2nd hand here in Denmark. They are still stupid.

Just curious though what is your pabel refresh rate? + What do you get if you reset wattman so it defaults to balanced.
What temps clocks and voltage do you see in a game,?

I had to repaste mine a few months ago, and it definitely helped.

Ok so trying Serious Sam 3 (2017). At first I thought it was o.k. Card at balanced settings clock speeds hovering about 1450-1560mhz (not bad). Then i'll notice if I stand in certain places the clock speeds will tank to about 1100mhz in places. Temps were at 65c. So I thought I'll increase PL to 50%. No difference to the drops. Then I put fan speed to 100% and temps drop right down to 40c but still 1100mhz..

You can actually see the lights on the card seamlessly firing up all lights and switching some back off as soon as the camera looks over certain areas. When this happens the card is barely using 100w.

Roll back drivers to June time. Keep the GTX1080Ti until next year mate. Is a good card.

Vega 64 curb stomping the 1080 Ti again, this time in Forza Horizon 4. Paid £360 my Pascal killer xD

Look at the 480 and 580 though, now beating the 980ti lol

Nvidia gimping in progress...

Previous gen top-tier cards now being beaten by AMD's 970/1060 equivalents.

So, it seems WCCFTech were right all along, The 480 is a 980ti beater. :rolleyes:

Ok but in those situations where it's barely using 100w is the frame rate right up to your refresh rate, and do you have any v-sync. frtc, or fps cap on?
If you have then that sounds right, as the gpu will reduce it's workload to maintain the fps target.

If I put say 90fps cap it will use around 55w and lower the clocks right down but If I take the cap off completely, the fps only goes up to 110fps 80-100w. In some similar places the fps can go well over 200fps when the card is on full power.

Vulkan API doesnt seem nearly as bad, only 1 power light goes off, but unfortunately afterburner stats wont show up using it.

While it's doing that it's switching power states (P states). For instance when I'm in iRacing and I don't lock it to P6 and P7 then the card will generally run at P3 state. Basically the card isn't under enough stress to require full power. Personally though when gaming I lock to P6 and P7 active for the Core and the P3 Mem state (max frequency for the Mem) so it doesn't drop or raise states as when it does I notice it microstutters. In some games it switches between P6 and P7 and in those I just lock to P7 to again prevent state switching.

I use OverDriveNTool as Wattman is a bit unreliable with the amount I change profiles.

Success!

Whilst I realised the lights represent p1-p7 I didn't realise they would not always just aim for p7.
But first I did manage to resolve the 1100mhz issue by disabling the CPU OC through Bios and setting it through Ryzen Master (I have no idea why this always seems to get better results. I thought it was only in 3d mark physics test but guess not). After this the drops were only to 1422mhz.
Then I disabled 16 threads on the CPU and got it to maintain abover 1500mhz. Finally I swapped the power cables to use 2 individual cables off the psu and after your advice I set p7 to min state and would you believe it I'm getting almost locked 1600mhz in this game without touching voltages yet.

He needs to also check out iChill. Cracking bit of software that reduces power usage when GPU not in full use.
