Amd Radeon Rx 580x With 8gb Gddr5 Review

The AMD RX 580 is at present the smart elderberry statesman of the electric current Radeon lineup, but when it first arrived the mildly updated Polaris GPU was actually a bit of a disappointment. Not simply were we hoping the 500-series cards would herald a new globe of Vega-based graphics cards (which ended upwards beingness their own unique brand of disappointing), it was barely any different from the RX 480 that had landed a year earlier.

Merely a year and a half, and one crypto mining boom later, the RX 580 has managed to evangelize on the 'fine wine' hope that AMD attaches to all of its silicon. It's now the graphics carte du jour that we would recommend as the best GPU to drop into your gaming rig… unless you take an infinite coin tree and can spend $1,200 on an RTX 2080 Ti anyways.

It's an impressively powerful, well-priced graphics card, with a comparatively huge pool of video retention and an aptitude for dealing with modern graphics APIs. And at just $190 (£197) it has very little contest in the market, with Nvidia's GTX 1060 only giving it interruption in a few DX11 titles and still being more expensive on the whole. Even the new GTX 1660 Ti struggles against its genuine value proposition.

t does have a lilliputian more than competition in the mainstream market right now, with AMD launching its 'new' RX 590 graphics carte du jour. That's just a moderate 12nm dice-shrink of the Polaris GPU at the heart of the erstwhile RX 580, simply information technology'southward as well a timely reminder that AMD'southward mainstream graphics cards are your best bet for great-value gaming functioning correct at present.

Even with the GTX 1660 Ti being unveiled its GTX 1070-level gaming performance keeps it some other pricing tier above the RX 580. The straight GTX 1660 might have something to offer, however, with its slightly chopped TU116 GPU and $220 toll tag.

AMD RX 580 specs

Polaris Enhanced. That'south what AMD chosen the updated 500-series of graphics cards, but they were never expecting to encourage anyone that spent their cash on a terminal-gen Polaris card to upgrade. Despite calling the GPUs at the heart of both the new RX 580 and RX 570 Polaris 20 it is still really the same 14nm Polaris 10 fleck they used, to great effect, in the RX 480 and RX 470 cards.

The 'enhanced' bit comes from the fact that 12 months on from the initial Polaris release both the 14nm FinFET engineering and the 4th Gen GCN architecture used in the latest AMD Radeon cards had a full yr to mature. That means the production process and yields improved and the resulting GPUs were more robust.

That'south the principal reason AMD take been able to release RX 580 cards with a higher base of operations clock speed than the reference RX 480 cards saw at launch. The base/boost clocks of the original RX 480 were 1,120MHz and 1,266MHz respectively, while the reference spec of the RX 580's Polaris 20 chip is set up at one,257MHz and 1,340MHz. With the general tightening up of the GPU'south manufacturing process AMD can ship out cards using pretty much the previous chip'southward pinnacle performance as a starting point to work upwards from.

Though if you lot were hoping for the same 40 compute unit, 2,560 cadre, Polaris GPU Microsoft shipped with the AMD-powered Xbox One X you'd be disappointed. Outside of the reference clock speed bump the RX 580 is the same GPU creature as the RX 480. The core configuration is identical – the 14nm Polaris twenty in the new carte du jour is still sporting 36 compute units (CUs) with 2,304 stream processors spread out across them. Alongside that are the aforementioned 144 texture units and 32 ROPs.

The retentivity system is the aforementioned too, with 8GB of GDDR5 delivering a full 256GB/s of memory bandwidth. And, like the 400 series cards, in that location are both 4GB and 8GB versions of the RX 580, also as the RX 570.

All that seems to have really changed then, clockspeed hike aside, is the new RX 580 cards have a higher TDP to allow for the enhanced clockspeeds the new designs are shipping with. Those clockspeeds higher up are merely the suggested reference design specs, simply the fact AMD never created any reference samples for the new cards was indicative of their refresh/rebadge condition, and besides that most RX 580 cards would be expensive mill overclocked ones fifty-fifty if the prices weren't being artificially boosted by the gluttonous mining community.

Our XFX sample runs at 1,366MHz, while the Asus STRIX card hits a heady one,411MHz out of the box. The original STRIX edition of the RX 480, on the other mitt, runs at a default one,330MHz. That itself was a pretty hefty boost in factory-overclock terms, just the new variant from Asus is about 100MHz ahead of that.

AMD RX 580 performance

The RX 580 is only a fiddling backside the newer RX 590 in terms of overall gaming performance, and generally there is only ever a few frames per second on boilerplate between them. That's something of a surprise given the significantly higher clock speeds offered past the updated, 12nm cards.

That'due south not actually the key battlefield for the RX 580, however. How it performs against the Nvidia GTX 1060 is where the real fight is, and that's far more interesting. On the whole the AMD Graphics Cadre Next architecture has the edge in overall gaming performance. There are a few instances where the Nvidia GPU holds sway, but that's just ever in last-gen DirectX 11 games. In the more modern APIs, and DirectX 12 in particular, the AMD silicon has the GeForce card beat.

When you have a step upward in gaming resolution the improved retention subsystem of the AMD carte comes to the fore. With another 2GB of GDDR5 memory, and a wider 256-fleck retention bus, the RX 580 in 8GB trim is improve able to deal with the rigours of high-res textures and the extra overall pixel count.

That's not to say the GTX 1060 isn't nonetheless a great performer at this finish of the market place, it virtually certainly is, but when the performance is so close pricing becomes an fifty-fifty bigger consideration. And when the RX 580 just has the edge on gaming frame rates overall, and the edge in pricing, information technology doesn't look good for the GeForce card.

Where the Nvidia GPU does have a significant border, all the same, is in the classic GeForce efficiency. Back in the Maxwell days Nvidia fabricated a play for efficiency when it was unable to action a silicon die shrink, and that move is withal paying off. The GTX 1060, outside of its reference cooler design, ofttimes runs libation than the RX 580, but definitely draws far less ability to game at almost the same level.

AMD RX 580 verdict

The RX 580 is hands-down the all-time-value graphics card on the market today. With the pricing problems of the mining boom times a distant retentiveness, the RX 580 8GB cards tin be picked upwards for as fiddling as $190 (£196), and that'south a comparative deal. Given the fact the closest Nvidia competitor card is oftentimes well over $250 it's really quite tough to recommend the more expensive GeForce GPU despite its improve overall gaming performance.

That'southward still a huge amount of coin for near of usa to spend on a unmarried component for our gaming PCs. Certain, we'd all love to be able to spend RTX 2080 Ti coin without pause, just in the real world even ducking under that $200 mark can be daunting. And at the $200 level AMD has the market sewn upward, though possibly the GTX 1660 will have something to say most that…
