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

AMD Radeon RX VEGA 64 Arrives For Testing

Ready or not AMD’s answer for a high-end series of consumer desktop graphics cards is finally here!  The Radeon Technologies Group is launching the Radeon RX VEGA 64 and Vega 56 today. The AMD Radeon RX VEGA 64 is powered by the full fat VEGA 10 GPU that contains 64 Compute Units and 4096 stream processors. You can get this graphics card with liquid cooling or an air cooled solution in a standard version (black plastic fan shroud) or limited edition (silver brushed aluminum) model. Then there is the VEGA 56 that has 56 Compute Units and and 3584 stream processors that is only going to available as an air cooled card. The AMD Radeon RX VEGA NANO was announced back on July 3oth when AMD revealed the Radeon RX Vega series, but we haven’t heard anything about it since.

AMD Radeon RX VEGA Specifications

When it comes to clock speeds the AMD Radeon RX VEGA 64, in both Limited Edition and standard versions, will have a base clock of 1247 MHz and a boost clock of 1546 MHz. The liquid cooled RX VEGA 64 has a base clock of 1406 MHz and a boost clock of 1677 MHz, so you can see that water cooling dramatically increases the clock speeds for this GPU! The AMD Radeon RX VEGA 56 has a base clock of 1156 MHz with a boost clock of 1471 MHz.

When it comes to memory all of the cards have 8GB of HBM2, but they are running at difference clock speeds. Both the air and liquid versions of the AMD Radeon RX VEGA 64 have an effective memory clock speed of 1.89 GHz and that is good for 484 GB/s of total memory bandwidth. The AMD Radeon RX VEGA 56 has the HMB2 memory running slightly lower at 1.60 GHz and that reduces the total memory bandwidth down to 410 GB/s.

AMD Radeon RX VEGA 64

Both the AMD Radeon RX VEGA 64 and Radeon RX VEGA 56 standard air cooled cards look the same, so we’ll just be showing you one of them. For starters the Radeon RX Vega 64 is a blower-style dual-slot graphics card that looks similar to previous generation reference cards from AMD. It has the usual red/black color combination, but the font for the Radeon logo has been updated.

Note that along the top edge of the card there are two 8-pin PCIe power connectors. With a board power of up to 345 Watts (liquid) and 295 Watts (air) at stock speeds these two connectors will come in hand especially when overclocking. There is also a vBIOS selector that allows you to switch between two different vBIOS profiles on this card. There are two vBIOS profiles and then each has three software controlled power profiles. That means there are six power profiles on each VEGA card!

AMD Radeon RX VEGA 64 Back

The back of the card does have a backplate, but it’s just for protection, to help stiffen the PCB and looks. There are no thermal pads on the back to help cool the GPU or any of the VRM components.

AMD Radeon RX VEGA Video Outputs

 

When it comes to video outputs for display connectivity, you have three standard full-size DisplayPorts and a full-size HDMI.

Let’s take a look at the test system and then run the benchmarks!

    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.
