AMD Radeon RX Vega64 8GB (Air) Review

Note: As already outlined, we had very little time to work with RX Vega64 (due to the proximity to Threadripper’s launch). As such, our overclocking testing has been very brief thus far. We continue to test overclocking and gather data and will update this page accordingly.


Update (14/08/17 at 18:00): Overclocking with the current state of available drivers is practically broken. The pre-release performance driver allows the card to be ‘overclocked’ to its maximum core frequency of 1980MHz but the actual clock speed never updates, as proven by identical performance results and similar power draw (when accounting for the increased power target). The ‘overclocking’ driver rushed to reviewers by AMD looks to result in nothing more than a black screen, system freeze, or lower-than-stock core speed when overclocking.

We will revisit overclocking performance when a more mature driver becomes available.

Brief overclocking testing using WattMan gave us some decent gains that give us more hope for our additional overclocking testing currently being conducted. Increasing the power target to 35%, setting the fan to around 66% (no higher in the early hours of Monday morning due to its sheer noise output), and using default voltage, we hit a frequency increase of 12.5% with stability.

Clock speeds throughout the five runs of Fire Strike Ultra Stress Test were 1832MHz and 1727MHz. The core spent more time at 1727MHz once the temperature had increased to 85°C (despite the higher fan speed). Power draw from the wall increase by almost 100W to around 550W.

We will continue to test overclocking performance with our RX Vega64 air-cooled sample. We have heard reports that 1900MHz may be possible and the brief time it took us to see 1727-1832MHz gives us confidence in pushing higher.

    Has anyone found a store actually selling these in the UK yet? Release date is today, but can’t find anything at overclockers.co.uk, amazon.co.uk, etc.

  • Steven Morrison

    What a shocking bad cooler. Will wait on some partner cards before making a decision. Power consumption looks dire too. 🙁

  • obimas

    Scan and overclockers got some stock

  • KVragec

    1900 MHz? How much power will then need to be delivered to it 😀

  • Rerry1000

    kinda disapointed because to me, this VEGA won’t make my fury X obsolete, delivery 95 FPS 1080p on Deus ex, the fury delivery 85 fps on 1080p, to me at least isn’t a great evolution :/

  • Varinder

    The prices on Overclockers for the Vega 64 is £548.99 for the cheapest and £599 for the special edition..though not in stock…The cheapest GTX 1080 reference on Overclockers is £449.99 and in stock.. a £100 price difference.. It’s got get to the price of the GTX…please!

  • TEAM GREEN

    A factory overclocked GTX 1080 G1 gaming by Gigabyte is only 519USD on Amazon.

    I’m sure you could find cards costing 499 by other vendors

    Vega 64 even in 499 isn’t worth it when you consider the price to performance to TDP.

    GTX 1080 is a better buy if you care only for gaming performance and TDP….unless you want mining in which Vega 64 might be better.

  • Joeyjoejoeshabadooo

    I get what you’re saying, but it’s not meant to be a 1080p-optimised card
    It’s hitting 1440p very well, but is still lagging in 4K. It’s an upgrade compared to Fury X, and probably noticeably in games, but it probably won’t blow you away like a 1080TI would. It’s cheaper than the TI, but still disappointing that AMD isn’t going after high end anymore.

  • WhiteSkyMage

    I will wait till board partners and custom bioses so I can OC this beast. A Vega 64 LC board with a EK waterblock in my loop and 2 bioses would be just awesome. I just hope the drivers arrive and enable primitive shaders, Rapid packed math and fix the HBCC. I won’t treat these benchmarks as final and would take them with a grain of salt. Besides, you are NOT playing the games, you are using the in-game benchmarks which are INACCURATE, so ALL the KitGuru benchmarking are UNRELIABLE!!!!

  • TEAM GREEN

    No one in their right mind should buy a Vega 64 at 1080 prices when you consider its gaming performance and TDP.

  • BntyHunter

    Lol you are obsessed with TDP. No gamer should care. Can you give it enough power? Can you keep it cool?

    Your arguing a point that means little since this cards power delivery was build almost perfectly.

  • BntyHunter

    You should not be as you don`t know what the card will do once its optimized for the game. Once more Dirt 4 changed 1 AA setting and it went from neck and neck with 1070 to smashing it by 24%. Also when I look at the games it struggles in they are mainly past there prime, like GTA 5 and if someone tweak cache settings this Vega will take off like a rocket.

    The one thing HBM simply cannot be argued about is how insanely powerful it is calling massive textures as well as limiting the low frame dips.

    I notice micro stutters and frame dips 100x more than a 10 FPS difference past 60 TBH.
    And I am really going for that. Hopefully it blows the doors off the current lows.

  • BntyHunter

    Power doesnt matter as much on here because normally we equate tons of power with heat. But this VRM is at the realistic limit almost at 91.5%

  • BntyHunter

    Pls link it. I have been looking for a long time twice daily, and because Nvidia slacked when miners first appeared they have been wiped out.

    Also why should gamers care about TDP at all? Its the miners who should. Gamers in general have much higher PSUs than normal as well as spend tons on parts they cant even use all the way “Hello 1080”.

    If anyone is using the 1080 for 1080P at any level the 1080 is a massive waste. And this is where the 56 Vega is so great, it blurs the 1070/1080 line.

    Hell the best bang for buck card that is worth it as much as a 1070 is the 1050TI for its price.

    It has always been said the 970/1070 lines are the high sweet spot while 960/1060 was low sweet spot.

    TDP only matters if the VRM is iffy. Vega has the best VRM made in a while and so even with huge power input it doesn’t get limited by thermals, its limited by power, which once more better for gamers.

    I am going to either get a 1070 or Vega to replace my 970. Basically the reason im leaning hard Vega now is Free Sync. Running 100 FPS is a odd but very nice spot in games and Gsyncs are just insanely priced.

  • Rerry1000

    yeah, I only sad that’s VEGA isn’t make Fury X obsolet, worth it more get a second fury x than a new VEGA…
