Poll: The Vega Review Thread.

What do we think about Vega?

  • What has AMD been doing for the past 1-2 years?

  • It consumes how many watts and is how loud!!!

  • It is not that bad.

  • Want to buy but put off by pricing and warranty.

  • I will be buying one for sure (I own a Freesync monitor so have little choice).

  • Better red than dead.

Results are only viewable after voting.
56 a good buy at £380, bios mod it, but not a good buy if you have to upgrade your PSU to get it as it has higher PSU requirements than a 1070, not everyone has over provisioned PSU capacity in their system.

Also I think the fact retailers or at least OCUK has (not checked other retailers) managed to keep the 56 price reasonable, suggests to me OCUK were not guilty of the 64 pricing fiasco, as I doubt the 56 has lower demand than the 64.
 
Have a look in the v56 thread for numbers, i got the bios from techpowerups big repository - might try the 64 liquid one later if i can be bothered.


Edited to say i really do not believe those psu figures, mine is pulling just 450-460w at the wall overclocked/undervolted with a 4.5ghz 5820k and about 2 millions fans :p:p

You really dont need a 1.21 GW psu for this thing :D
 
450w at the wall is high for a modern PC :)

my haswell with my 1070 pulls about 150-200w in game, and about 250w if I really stress the card (like hash operations unthrottled power usage).

My mini-ITX system with a GTX1080 draws more power than that when gaming with an IB Core i7 ,and you are forgetting he is using an X99 system,not a much lower power consumer CPU too! ;)

I am using a Corsair SFX450 SFF PSU. Corsair uses the SFX500 in their top end Corsair One with a GTX1080TI.

The fact of the matter is anyone with a decent 500W PSU can run something like a Vega56 fine - you are in the review thread after all:

That is with a Core i7 7700K at 4.9GHZ BTW and those are at the wall,so the internal load on the PSU is less.

Another with a less taxing game.

A benchmark.

Nvidia is ahead in efficiency OFC,but still looking at most build threads here,many are probably overspeccing their PSUs!! :p

I dont get why its better, cant you just change 56 clocks anyway. Or is this bios unlocking HBM speed to more

Well it should OC the HBM automatically so, and I guess ups the max HBM voltage to 1.35v which I don't think is possible on the 56 bios is it ? So obviously it makes it faster at stock, but the 64 bios also ups the power limits, I think that it makes a difference even when undervolting (especially when going into the P7 state), because, by the looks of it from GNs fiddling around, the GPU/drivers/bios can also "ignore" the core voltage and up it briefly when needed to maintain clocks.

Also there is something that hasn't been talked about much and i'm curious on getting an answer for this, AMD said that the GPU is capable of clocking dynamically down to 1 mhz increments to be able to fine tune the power consumption (with a minimum of 27 mhz on the core) and that is apparently something new for AMD, now i'm wondering if there isn't some kind of "furtive" dynamic clocking and power adapting that is going on that isn't being picked up by the monitoring apps

Cant agree with that, 56 looks like a very solid card. At £380 ish it kills the 1070 stone dead, it also gives the 1080 a very hard time after fiddling (ok i know you can also get other cards overclocked as well...) and thats all on a driver set that is still half baked and strewn with bugs..

LOL.

This joke just keeps getting funnier.

AMD/RTG employ thousands of people. They have more than one driver guy. First we had "oh, they're just Fiji drivers, when the real Vega drivers are released we could have +30% perf!". Then it was "There are loads of features that aren't working/enabled yet". Now "The drivers aren't ready and are fully of bugs."

All from a couple Tweets by Raja, interpreted very, very loosely to mean whatever people want them to mean.

But if you just read what AMD have said and don't try to put any spin on it, there's little reason to believe new drivers will deliver massive improvements in Vega.

So just like the non-existent future DX12 improvements for Pascal once Volta lands. Vega won't lose performance in DX12 because that was what it was built for but Pascal is already showing its age in DX12. For the next two years I'm happy with my choice thank you.
 
How many times do people need to be told, Vega cannot compete with Gp104 at price.

Wow pretty conclusive there, back to 2019 you go then.

I'll keep this card for two years for sure as I've no interest in 4K. What's wrong with that. I paid £449 for my Vega 64 AC so with freesync monitor it's a no brainer really.

Sure if you're happy with it then that's cool, It depends on what hardware the individual has to make the judgement of whether the upgrade is worthwhile. My point on the sarcasm is more about your future scope of dx12 being a justification towards purchase.
 
I agree a 56 should be fine with a 500w psu providing it has a decent 12v rail.

I wasnt blaming his high power load entirely on the GPU, I just said it was high :)

I think the reviewers figures are high as well. I think the reason is that my cpu has very moderate voltages set (I refuse to run any cpu over 1.21v, yet many run 1.35v as routine). I also keep c states enabled, whilst many overclockers turn it all off. So I expect these inflated power stats, will be down to the cpu as well.

On my mining rig I have 2 gtx 1070s running on one 500watt PSU after someone told me I was crazy to use that PSU for 2 1070s and pulling over power 240w at the wall not even half the PSU capacity. Most enthusiasts tend to massively over provision on PSUs. Although both those 1070s are power limited to 70%.
 
liking the 56 so far, spent the last couple of days just tweaking and benching but last night gave a it a proper gaming session, ran doom on max settings @3840x1600, i didnt limit the fps as i wanted to see if and when it went above and below the freesync range.
working out pretty good so far and did not drop below the 55 range and was getting mid 70's 80's most of the time and a few highs of 100 and odd so im going to need to limit the fps to 74.
i knew doom would be the best case scenario so going to try rise of the tomb raider later as i think this will be worse case scenario

Good price. And for under 4k res., should serve you well.

And probably for more than two years, tbh (I don't see any games on the horizon for the PC that will crush any relatively new card for the next several years..)
