Power Consumption

This board’s 238W of power consumption in a gaming workload almost reaches the level of AMD’s Radeon RX Vega 56.

The 245W we measure during FurMark is ultimately only constrained by XFX’s power limit and the cooler’s inability to keep up. Spikes as high as 300W are downright unbecoming of a mainstream graphics card.

Voltage readings averaging 1.18V during our gaming sequence are right about what we expected. They remain consistent so long as the card isn’t thermally bottlenecked.

Load distribution between the rails is good, as our motherboard’s PCIe slot never even comes close to the maximum-allowed 5.5A. Compared to the first Polaris-based cards, which violated that limit, AMD clearly learned its lesson and is now configuring power consumption correctly.

The following graphs illustrate power consumption and current flow over time at idle, during a gaming test, and in FurMark.

    The further cut-down Vega sounds like it could have been a better option to me, primarily if they could make it work with GDDR5, GDDR5X, or GDDR6 memory.

    Wonder if we will see a RX 590X in a month or 2. Higher bin chips passing this overclock and with say GDDR5x 9GB memory.

    A conclusion & a possible editorial mistake:
    1. A used GTX 1070 for slightly over $200 is a better value today for 2k gaming.
    2. It seems that in GTA V & Metro the slides were mislabled - the 1080p were placed under 2k and viceversa. Look at the presented framerates in those two games & you'll see that 1080p results are worse than 2k;)

    I hope you are joking because this RX 590 is the already the higher bin chips.

    Good eye! :)
    The perf difference is actually from turning off SSAA at 2560x1440 in Metro and disabling 4xAA at 2560x1440 in GTAV as we try to keep QHD a playable resolution. Maintaining the same quality settings would have hit that res too hard.

    238W of power while gaming? That is unacceptable. 7nm cards can't come soon enough for AMD.

    580s readily available for price point less then they launched at LMFAO

    Yep, but that would require complete remaking that chip. Well Hopefully good Ryzen selling Numbers give money Also to gpu department so that They can afford to completely rehaul their low end and middle range cards. Even this 12nm with that 7.5 library would offer good gains if paineen with refress in architecture. But that remain to later timeframe. New card will require a couple of years, so if and because the company is in right track, one or two years From now there will be improvements if They start now the developmening it.

    "Once again though, we've observed that VRAM is never enough. It was only a few years ago that 8GB of VRAM was considered excessive, only useful for 4K. But especially with the popularity of HD texture packs, even 6GB of framebuffer could prove limiting at 1080p with graphically demanding games. In that respect, the RX 590's 8GB keeps it covered but also brings additional horsepower over the 8GB R9 390. For memoryhogging games like Shadow of War, Wolfenstein II, or now Far Cry 5 (with HD textures), the 8GBs go a long way. Even at 1080p, GTX 980/970 performance in Wolfenstein II tanks because of the lack of framebuffer. For those looking to upgrade from 2GB or 4GB cards, both the RX 580 and RX 590 should be of interest."

    So as you can see 480/580 and 590 do benefit from the extra vram even at 1080p. I do feel all those people who asked on various forums on whether to buy 4gb or 8gb and got recommended 4gb since they were playing at 1080p were wronged as just a year or two later games are now benefitting from larger than 4gb framebuffer. Now those people will have to upgrade their cards sooner rather than if they had 8gb model they would have been able to keep the card longer.The forums can sometimes give wrong advice to people and screw them over.

    AMD got some awful diminishing returns from overclocking a 580. I wonder if we would see better returns if they reconfigured the cores and ROPs instead of using a 580 as the foundation.
    I'm disappointed with the 14nm -> 12nm transition. It seems like it did nothing to help with power consumption or heat. I was hopeful because it was helpful in regards to AMD's Ryzen chips.
