The AMD Radeon RX 590 Review, feat. XFX & PowerColor: Polaris Returns (Again)
by Nate Oh on November 15, 2018 9:00 AM ESTFar Cry 5 (DX11)
The latest title in Ubisoft's Far Cry series lands us right into the unwelcoming arms of an armed militant cult in Montana, one of the many middles-of-nowhere in the United States. With a charismatic and enigmatic adversary, gorgeous landscapes of the northwestern American flavor, and lots of violence, it is classic Far Cry fare. Graphically intensive in an open-world environment, the game mixes in action and exploration.
Far Cry 5 does support Vega-centric features with Rapid Packed Math and Shader Intrinsics. Far Cry 5 also supports HDR (HDR10, scRGB, and FreeSync 2). This testing was done without HD Textures enabled, a new option that was recently patched in.
Far Cry 5 shows the same trends as Battlefield 1, with the RX 590 splitting the difference between the GTX 1070 FE and GTX 1060 6GB FE. At 1440p, that level of performance brushes close to the 60fps milestone, not a surprising feat as the original RX 480 8GB proves itself on par with the GTX 1060 6GB FE. Like Battlefield 1, this is the general space that the RX 580 wants to be in, where its performance can act as a spoiler for the GTX 1070 FE and mitigate increased prices and power draw.
As we'll see later, the lower VRAM options in this upper mainstream segment make it clear that 8GB is really the new level of broadly sufficient video memory, especially for cards expected to be in service for a few years. As it so happens, Far Cry 5 released a free 29GB patch adding toggleable HD Textures, which we will look into benchmarking. Generally, high-resolution texture packs are a simple way of increasing visual fidelity without significantly hurting framerates, provided the card has enough framebuffer. This can especially benefit those mainstream cards, particularly those on 1080p rendered on larger displays, as every passing year is often another exercise in figuring out what quality settings to dial down.

It would be an unfair comparison because AMD is using GLOFO 12nm LP node designed for low clocks and mobile parts, whereas NV is using TSMC 16nm high performance process designed for high clocks and efficiency.You can't compare the two back to back and NV would still win in such a situation.
But, for the sake of argument, a Polish website (at least I think it was Polish) apparently managed to undervolt RX 590 just recently and total power consumption dropped by 34W.
Here's the website:

Polaris power consumption problems stem from a combination of problems:
1. (and this would be the biggest) GLOFO 14nm/12nm process nodes designed for low clocks and mobile parts (not worth it even raising frequencies on 12nm because as we saw, both Ryzen+ and Polaris were already boosting WAY past the GLOFO node 'comfort zone' to the point efficiency was thrown out the window.
2. lower yields on GLOFO nodes contributed towards lack of voltage optimisation resulting in higher maximum voltages on GPU's shipping from factory.
3. Excessive amount of compute hardware. Polaris has powerful compute which is not really used in games, and this hardware does suck up a lot of power, and Polaris in general has about 40% more stream processors than Pascal has CUDA cores.

I still don't see any incitement to upgrade from my 290X, sad in a way.. : /eva02langley - Friday, November 16, 2018 - link
Vega 56 if they are on sale for the right price...However yeah, no reason to change.

How long will AMD keep squeezing the blood out of Polaris? They have practically abandoned their GPU division, their mainstream one anyway. A single refresh could be occasionally justified, but a refresh-squared of the same GPU (or GPU series) equates with rebranding.I realize that they overwhelmingly focused on their CPU and APU division in order to compete with Intel, and that drew resources and engineers from the GPU division. But competition is required in the GPU market as well, or else Nvidia will keep charging an arm and a leg for their graphics cards.

you didn't mention in the Wolfenstein 2 page, that the RX590 performs like a GTX 1070. It's an interesting observation that should be investigated.deksman2 - Friday, November 16, 2018 - link
Probably because the game is well optimised for AMD hardware (a situation which is all too uncommon).But AMD's main problems stem from using an inefficient GLOFO nodes.
14nm and 12nm were both designed for low clocks and mobile parts... this is why we see massive increase in power consumption for Polaris at high frequencies... because the GPU is clocked WAY past the voltage comfort zone where it would be efficient.
TSMC nodes are designed for high clocks and efficiency... and as such, they WILL have an advantage in clocks and power consumption.

Does this win the award for most pointless launch of all time? Anyone who was in the market for a GTX 970/1060 class GPU in the GTX 970/1060 price range probably bought a GTX 970 or GTX 1060 already. Releasing a more power hungry card over 4 years late doesn't really seem like it's going to move the market.When Nvidia was 6 months late with the housefire GTX 480 they at least had the performance crown compared to the 5870. This is 4 years late and has nothing.

Seems like a used RX 480 8GB is probably the best value out there for 1080 gaming. Plenty of them for about 100.00 on ebay. I keep looking for the price of 1060 6GB cards to come down now that there is a glut of them, but they stay stubbornly high.neblogai - Sunday, November 18, 2018 - link
RX570s are about as fast as RX480, but start at ~$150. They are new, come with warranty, and with 2 AAA games which can be considered to be worth ~$120 if you want them, or ~$60 for reselling. RX570 is a better deal.
