Performance Summary & Conclusion

Performance summary charts 

Below are the summary charts of 20 games and 4 synthetic tests. The highest settings are always chosen and DX12 is picked above DX11 where available.  Specific game settings are listed on the charts and the benches were run at 1920×1080, 2560×1440, and at 3840×2160.  All results, except for the synthetic benchmarks show average frame rates and higher is always better.  Minimum frame rates are shown when they are available, next to the averages but they are in italics and in a slightly smaller font.

The GTX 1070 FE stock results are presented in the first (dark green) performance results column next to the second (lighter green) GTX 1070 overclocked results; the overclocked RX Vega 56 results are in the first (lighter red) column, and the next (darker red) column represents the stock RX Vega 56 results.  The first yellow column represents the percentage performance increases of the overclocked GTX 1070 over stock, and the last yellow column represents the performance percentage increase of the overclocked RX Vega 56 over its stock-clocked results.  Finally the stock GTX 1080, the stock RX Vega 64 Liquid edition, and the stock GTX 1080 Ti are shown in the last three columns for comparison.  Yellow numbers show “wins” between the GTX 1070 and the RX Vega 56.

The following 3 charts may be easier to read when opened in separate tabs or windows.

Rainbox Six: Siege got a new major update and performance has increased with the new patch.  The GTX 1080/Ti and Vega 64 were benchmarked before the update and should not be compared with GTX 1070/RX Vega 56 results.

The $399 stock-clocked GTX 1070 FE wins 10 individual game benchmarks to the $399 RX Vega 56’s 50 games.  And even though both cards overclock decently, the overclocked RX Vega 56 loses a little ground winning 44 game benchmarks, while losing to the overclocked GTX 1070 FE’s 16 wins.

Let’s head to our conclusion.


This has been quite an interesting exploration for us evaluating the overclocked $399 RX Vega 56 reference edition versus the overclocked $399 GTX 1070 FE.  The RX Vega 56 is a faster card than the GTX 1070 FE.  Both cards overclock decently, with the RX Vega 56 gaining a very nice memory overclock which greatly increased its performance over stock.  However, the GTX 1070 FE is a stronger overclocker percentage-wise, and it gained more consistent performance overall from overclocking than its Vega 56 competitor did.  

Both cards appear to scale well with overclocking although the GTX 1070 FE overclocks further and uses significantly less power doing so than the RX Vega 56.  We could not recommend the RX Vega 64 over the GTX 1080 except perhaps in specific situations where the gamer already has a FreeSync display, but the real star of AMD’s Vega constellation appears to be the RX Vega 56 if it can maintain its $399 pricing versus the GTX 1070.  

The main issue that we can see is that the Vega 56 reference version runs hot and throttles unless its fan is set very high, and we would recommend waiting for AMD partner versions.  We also don’t feel that one should be required to undervolt the core just to get a decent memory overclock, and we look forward to seeing AMD partner Vega designs and possibly improved power delivery.

Next up, we are putting together our new automatic adjustable Standing Desk, the VertDest v3, that we are setting up now for review as we build our Ryzen 7 platform.  Stay tuned.  In the meantime, if you have any comments or questions, feel free to post them in the comments section below, or on BTR’s Community forum.

Happy Gaming!



    • Yeah this site left fan on automatic at 2012mhz lol. You know that is mostly will degrade into 19XX mhz coreclock when temp goes higher.
      Also Pretty bad 1070 overclocking.
      1070 should be easily stable at least ~2050-2100mhz with proper cooling,
      Many 1070 Memory also can reach +600, +700 or so. +500 is the most basic.

  1. Hrmm.. this article might be a bit old. But the results are pretty poor for the Vega. I don’t have any experience of overclocking 1070’s personally but my reference vega56 is just fine with core @ 1650 and memory @ 1100 mhz.

    As you state here most gains will come from overclocking the memory. It scales more or less perfectly with memory frequency. But the trick is to keep the hbm modules below 82 degrees celcius. Or preferably under 80 since they are starting to loose efficiency above that. And. At 92 they will start to throttle.

    The thing about temperatures is that from my experience the hbm modules tends to run about 20 degrees hotter than the core at load. Atleast when running memoryheavy applications. Mining is a good example. When it comes to games it’s not as bad.

    But if you try to do some quick testing keeping the core between 60-65 degrees you should be able to gain way more from overclocking the Vega. My gain is typicly 23-25% above stock with makes it a clear overclockwinner. But, I want to be clear about that it comes with an acoustic toll if using the reference cooler.

    My tests are based on a msi Vega 56 running vega64 bios (air) and I have replaced the paste on the chips with liquid metal. (Only gained about 4-5 degrees).

    Over and out
