AMD Radeon RX 590 Review: Benchmarks And Overclocking 12nm polar star


AMD has had a reasonably sizable hole in its graphics card line-up for quite it slow currently. disregardless the craziness crypto-miners caused for a short while there, evaluation on the Radeon RX 580 has hovered round the $200 mark, whereas most of the Radeon RX Vega fifty six cards presently obtainable sell for over $400 – offer or take many greenbacks. additionally, there are no current-gen offerings discharged in between the 2. fortuitously, AMD hopes to deal with this case nowadays, however, with the launch of a semi-new GPU, the not-so-secret Radeon RX 590.

Over the previous few weeks, news of the Radeon RX 590 has steady leaked bent on the net. We’ve lined variety of the stories on the news page, however nowadays we will offer you the total scoop. we have a tendency to got some of Radeon RX 590 cards certain testing, specifically the PowerColor secobarbital sodium RX 590 and XFX Radeon RX 590 FATBOY, and born them into a freshly updated test-bed, aboard some of alternative GPUs for the sake of comparison. Before we have a tendency to get to the numbers tho’, let’s get some particulars out of the approach…

The underlying design and style of the Radeon RX 590 is comparable to the RX 580. the basic blocks within the GPUs area unit an equivalent – they’re each supported AMD’s polar star graphics design, have 2304 stream processors, a hundred and forty four texture units, 32 ROP, and similar cache configurations and memory interfaces. the sole real distinction is that the Radeon RX 590 is being factory-made employing a newer 12nm FinFET method, that has allowed AMD to crank up the GPU clock, whereas remaining inside an identical power envelope.

AMD’s reference style involved a liquid ecstasy boost frequency of 1340MHz for the Radeon RX 580, whereas the new Radeon RX 590’s counseled liquid ecstasy boost frequency is 1545MHz. There aren’t probably to be several reference Radeon RX 590s that hit the scene, however. just about all of AMD’s board partners area unit at the prepared with custom styles that conjointly happen to be manufacturing plant overclocked. Case in point: The PowerColor secobarbital sodium RX 590 and XFX Radeon RX 590 FATBOY we’ll be showing you here.

The XFX Radeon RX 590 FATBOY is stout graphics card, with twin fans and a triple-slot cooler. There’s no fancy lighting or badges on this card, although a fake carbon-fiber wanting texture on the shroud and some of basic stickers, however it’s got all of the fundamentals lined and therefore the outsized heatsink will its job well. A try of 100mm fans blows air across a thick heatsink array, joined by copper heat-pipes, that covers most of the front reality of the cardboard.

The FATBOY’s backside is out fitted with a unreal reinforcement plate, adorned with ventilation holes and an outsized XFX brand. The card’s options and most of its specifications mirror AMD’s reference specs, although the height GPU clock. The XFX Radeon RX 590 FATBOY has an equivalent core count and memory configuration, etc., however the boost clock can go all the high to 1600MHz.


Power comes by approach of a try of PCIe feeds – one 8-pin and one 6-pin, that is much over enough to accommodate the 185w TDP, and therefore the card incorporates a two-slot mounting bracket with some ventilation, however as mentioned, the cooler can extend past 2 slots, thus for all intents and functions the cardboard is 3 slots wide.


Outputs on the XFX Radeon RX 590 FATBOY accommodates a trio of full-sized DisplayPorts, associate HDMI port, and a DVI port, all of which might be utilised at the same time with AMD’s Eyefinity multi-display technology.


The PowerColor secobarbital sodium RX 590 is additionally three-slots wide, however incorporates a a lot of elaborate style than XFX’s providing. It too options a try of 100mm fans that sit atop an outsized heatsink assembly, however the shroud on the secobarbital sodium RX 590 options a dual-layer, crimson and black style on an equivalent lines as alternative secobarbital sodium cards, that we expect appearance nice. Similarly, the heatsink covers nearly the whole front of the PCB, and makes contact with the GPU, RAM, and VRM. 3 thick heat-pipes run from the baseplate, up through the array of heatsink fins.


There is conjointly a perforated reinforcement / heat-plate on the backside of the PowerColor secobarbital sodium RX 590, with some of labels on the highest edge that mirror the positions of a try of small switches. The PowerColor secobarbital sodium RX 590 has twin BIOSes on the cardboard, one for the quality overclocked mode and another for silent mode. within the overclocked mode, the card’s GPU can accelerate to 1576MHz, use associate magnified power target, and spin up the fans once the GPU hits 70’C. In silent mode, the cardboard reverts to reference specs (1545MHz boost), however the fans don’t begin ramping till the GPU hits 80’C, which implies the cardboard is actually silent till it’s been beneath load for a short while. The overclocked profile is something however silent, however we’ll chat this a touch later.

The second switch, merely tagged semiconductor diode switch, will be wont to disable the card’s inbuilt lighting.

The PowerColor secobarbital sodium RX 590 options a 6+1 power part setup and needs 2 PCIe power feeds still, one 8-pin and one 6-pin. Outputs area unit just like the XFX Radeon RX 590 FATBOY too, and accommodates 3 full-sized DisplayPorts, associate HDMI port, and DVI port.
