AMD Radeon RX Vega Benchmark Review: Vega 64 and Vega 56 Tested

Jump To:

Power Consumption

For testing power consumption, we took our test system and plugged it into a Kill-A-Watt power meter. For idle numbers, we allowed the system to idle on the desktop for 15 minutes and took the reading. For load numbers we ran Battlefield 1 at 1920 x 1080 and recorded the peak power number while gaming a particular level that we test on each card. Our idle numbers are high, but keep in mind that we are using a workstation motherboard that has two 10GbE ports and other high-power draw controllers on it.

Power Consumption Results: With the AMD Radeon RX VEGA 56 video card installed in the system we topped out at 457 Watts when running BF1 at 1080P resolutions. The AMD Radeon RX 64 video card used 510 Watts in the same test, so our testing shows the VEGA 64 uses about 65 Watts more power than the VEGA 56 while gaming. The AMD Radeon RX VEGA 64  power efficient card uses more power, makes more noise and got beat by the NVIDIA GeForce GTX 1080 Ti Founders Edition in every benchmark. The NVIDIA GeForce GTX 1080 Ti is not going to be dethroned today! 

Let’s wrap this review up!

    Ok, here’s some things ticking me off: The Vega 64 is literally twice the gflops, and twice the memory bandwidth of the RX 580. The gap from the Vega 64 to RX 580 should be huge. The GTX 1060 to 1080 may be basically as large Gflops wise, but is minimal memory bandwidth wise. And what do you notice in these benchmarks? What the bloody hell is going on? The Vega is a new architecture, it’s supposed to be better in all sorts of ways. Yet here we see the same architecture generation from Nvidia performing much better in line with the increases. Allow me to demonstrate:

    Cross multiply Nvidia GTX 1060 Gears 4 1080, using the RX 580 and you find the AMD if scaling as well, should be average 157 in the frame rate, before accounting for any leap from the new architecture. What does it turn in? 128. Nvidia is scaling better in the same generation than AMD is in the new one?

    Fallout IV: It should be 125 if it scaled as well as the NVIDIA card. It is instead 112.

    Ghost Recon:

    95 instead of 106

    Battlefield:

    131 instead of 153

    Deus Ex:

    112 instead of 125.

    Grand Theft Auto is the only one it scales a tiny bit better.

    It’s scaling WORSE in DX 12 than it is in DX 11 I might add, do the math.

    I bought the Vega 64 and I have to say I’m disappointed. I’m hoping these beta drivers are the reason, because this is absurd, and I might add, the card gets to 86c unless I turn the fans to “wind turbine” as well. I also seem to be having an issue with Batman Arkham Knight in frame rate, which I’m just going to chalk up to some weird sort of glitch, because it’s nowhere near where benchmarks peg it. This has got to be one of AMD’s most disappointing launches of a new architecture I have seen.

      haha, winner! Fixed and thank you.

    Was hoping for a card that’d make NVidia push Volta and create a realistic GPU war. Unfortunately, we got cards that compete with stuff that NVidia has had out for over a year and that draw too much power, in comparison. These are good cards, for sure, but they are a year too late. Vega 56 seems like a good option for some 1080P Freesync gaming, though.
