The AMD Radeon RX 590 Review, feat. XFX & PowerColor: Polaris Returns (Again)
by Nate Oh on November 15, 2018 9:00 AM ESTPower, Temperature, and Noise
As always, we'll take a look at power, temperature, and noise of the Radeon RX 590. As a custom-only specification, this means that we will be looking at solely AIB vendor designs. With the RX 590, we already know what to expect with existing RX 580 boards and coolers.
As this is a new GPU, we will quickly review stock voltages and clockspeeds as well.
| AMD RX Series Video Card Voltages | ||||
| Boost | Idle | |||
| Radeon RX 590 | 1.1563V | 0.8000V | ||
| Radeon RX 580 | 1.1625v | 0.7625v | ||
| Radeon RX 480 | 1.0625v | |||
Power Consumption
For all the gaming performance gains that the RX 590 has made, it came with the higher clockspeeds, and to bring those higher clockspeeds came more power. Already, TBPs have notably increased from the RX 480's 150W to the RX 580's 185W, and now to the RX 590's 225W. Which is already past RX Vega 56's 210W reference board power spec.
Idle power consumption doesn't show anything out of the ordinary.
The RX 590's load power consumption is a slightly different story. For the RX 580 launch, we mused that this is where AMD paid the piper. For the RX Vega launch, I commented that the piper had then taken AMD to the cleaners. For the RX 590 today, I thought there wasn't any more the piper wanted to take, but there was.
From the wall, the RX 590 now pulls 30 to 45W more than the RX 580 in Battlefield 1. The difference in FurMark is even starker, with the RX 590 now drawing 45 to 80W more. Naturally, the power delta gets higher when comparing to the RX 480, let alone the GTX 1060 6GB FE. In Battlefield 1, that's 110W or more system consumption than the GTX 1060 6GB FE for what is panning out to be around 10% faster performance. It's clear that the RX 590 is not in the same league - or anywhere close - to the GTX 1060 in terms of power efficiency.
Temperature
With all that power, heat and temperature can easily become an issue. But as both a non-reference launch and a product refresh, the featured open air axial fan designs are tried-and-true, and already configured to dissapate similar thermals.
Noise
Likewise with noise, the RX 590 can benefit from zero dB functionality, where fans turn off under certain temperatures.
Additionally, a quick glance at RX 590 power consumption at -25% and -50% power limits show that like the RX Vega, RX 480, and RX 580, Polaris 30 is well past the optimal point on the voltage curve with the clocks at hand.

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.
