Compute
Shifting gears, let’s take a look at compute performance on new Radeon RX 500 cards.
Starting us off for our look at compute is LuxMark3.1, the latest version of the official benchmark of LuxRender. LuxRender’s GPU-accelerated rendering mode is an OpenCL based ray tracer that forms a part of the larger LuxRender suite. Ray tracing has become a stronghold for GPUs in recent years as ray tracing maps well to GPU pipelines, allowing artists to render scenes much more quickly than with CPUs alone.
For our second set of compute benchmarks we have CompuBench 1.5, the successor to CLBenchmark. CompuBench offers a wide array of different practical compute workloads, and we’ve decided to focus on face detection, optical flow modeling, and particle simulations.

Tile-based rendering does wonders for power consumption. AMD is still doing full scene rendering, which is expensive and inefficient.Vega will join the TBR party. We'll see if power consumption has dropped significantly then.
But, isn't that the general rule when you OC? Throw power saving out the window. I have my old R9 280 at 1200MHz. Draws about 230W. Don't really care.

I was hoping to read something about Freesync 2 and moreso now after reading the review to find the performance gains weren't as exciting and not without caveats. Since there currently are no Freesync 2 monitors though, there is no point in reviewing this feature. It would have been a nice value added feature to help offset the minimal gains in performance. Too bad AMD couldn't capitalize on this feature to make this release more exciting.Cygni - Tuesday, April 18, 2017 - link
Keeping the memory specs down will help them move to undercutting the 1060 on price, which they will need to do pretty heartily to get some sales volume. Hopefully this is enough to encourage Nvidia into a price war, as they have been milking the 1060's pricepoint pretty heavily for a long time now. Other than a brief dip to the $210 range on black friday, prices have stayed pretty high on 6GB cards.brucek2 - Tuesday, April 18, 2017 - link
Most of us learn as small children the peril of crying wolf. You'll get a lot of attention the first time you do it, but if there's no actual wolf you'll soon get a bad reputation and no further attention.AMD is crying wolf here. These are not new generation products. The new numbering is essentially a lie. I still very much want there to be a real competitor to Nvidia / Intel, but crud like this is not making it easy to root for them.

New to the tech world? This is pretty standard stuff after a new arch. Nvidia has done it several times as have AMD. Guess what, Intel and AMD do it with their CPUs too. Oh my, looks like it happens with mobile SOCs too.haukionkannel - Wednesday, April 19, 2017 - link
It is norm to have rebrands by both makers. Same is true to cpus even more...tipoo - Thursday, April 20, 2017 - link
They were pretty clear early on that it was just an overclock of the 480, and that's what it is. Not sure what people expected. Would 485 be a better name? Probably, but that's the GPU world for ya.AbbieHoffman - Tuesday, April 18, 2017 - link
And yet the old R9 290X and R9 390X are still better cards.sonichedgehog36 - Tuesday, April 18, 2017 - link
