AMD's mid-range Radeon 500-series video cards are here

AMD's mid-range Radeon 500-series video cards are here

To try and fill the gap, AMD have launched a new range of 500 series cards, including the VR-ready Radeon RX 580.

"The Radeon RX 500 series was designed specifically for system upgrades, catering to the 9 out of 10 PC gamers today who are hindered by outdated technology and aren't able to enjoy optimal experiences in modern games, smooth VR experiences, or the latest display technologies". While RX 560 has full Polaris 11, i.e. 1024 cores vs 895 cores on RX 460, the RX 550 has a cut-down Polaris 12. AMD's first RX 480 reference cards had a problem with drawing too much power over the PCI Express slot and not enough via the auxiliary power connectors.

Finally there is the entry-level RX 550 that is created to appeal to the mainstream market and offer better performance than that offered by integrated graphics. In some cases, it even comes close to the Nvidia's GeForce GTX 1060.

However, if you are looking for RGB and other aesthetics then you can check out Asus GPUs.

Several users over at TechPowerUp have been flashing an RX 580 BIOS on their RX 480 cards. Early Radeon RX 480 were limited in how much they could overclock and increase voltage, so there's a decent chance that an RX 580 BIOS might not play nice with your card at all. It has a base clock of 1168MHz and boost clock of 1244MHz. The new naming scheme is apparently warranted by the improvements to the overall foundry process used in manufacturing the Polaris GPUs.

AMD Radeon RX Vega Possible Specs, Release Date: Next-Gen Graphics Card Is 'Almost Human'

Today's review will feature the Sapphire NITRO+ Radeon RX 580 8GB. Memory bus width is also identical to the 580, but AMD offers it with 4 GB VRAM exclusively. The increase in clock speed generates some concomitant increases in throughput, at least. It's actually half of an RX 560 and a third of an RX 570 since it has 1,183MHz boost speed. Bracing those units of frequency brings the rated TDP up from 150W to 185W. The RX 560 goes for $100 while the RX 570 costs $170 for 4GB. As noted by AMD, "Polaris refined and evolved".

Let's be totally clear: The RX 550 won't win any races, but it instantly makes games immeasurably prettier and faster than the discrete graphics built into an Intel processor. Radeon RX 480 was very well received by the enthusiasts, but its limitation was reached at a maximum of 1,266MHz boost speed.

But there's a catch: AMD shipped factory overclocked cards to represent the RX 500 series, so I'm giving Nvidia the same benefit and am testing two factory overclocked Nvidia models.

For all of those, pricing remains the same as with their predecessors: $229 for the RX580 with 8GB of RAM, $199 for the RX580 for 4GB, $169 for RX570 with 4GB, and $99 for the RX560 with 2GB. The RX 570 is aimed at those gaming at 1080p, where it is claimed to be 2.3 times faster than the R7 370.
