AMD's RX 500 Series Specifications, Performance Leaked

A leak of what appears to be AMD's presentation on the Radeon RX 500 series has brought confirmation on specifications and details of the new line-up - which includes the RX 580, RX 570, the (until now) missing RX 560, and the RX 550. It would seem AMD has now opted for a new, dual-fan reference design, instead of their usual single-fan, blower-style coolers.

The RX 580 has a base clock of 1257 MHz, and a boost clock of 1340 MHz (74 MHz greater than the RX 480's 1266 MHz). It's a Polaris chip alright, packing the same 36 Compute Units (2304 Stream Processors, and up to 8 GB of GDDR5 memory across a 256-bit interface. AMD apparently decided to compare the RX 580 to the R9 380, which allows the company to show some relevant performance improvements (which wouldn't be possible with the RX 480, now would it.)

Sapphire, MSI AIB RX 500 Series Cards Listed Online; Polaris 20 on Special, "GHz" Edition Cards

Vendor lists for RX 500 series cards keep popping up, and this time, it's Sapphire and MSI's time. And it would seem that Sapphire has just seen the entirety of its RX 500 series lineup leaked (sans the still absent in battle RX 560.) Apparently, Sapphire will launch a new PULSE line of graphics cards, in addition to its already known NITRO series. This new PULSE line of graphics cards will likely carry previous-gen Polaris 10 chips, judging from the difference in pricing between the top of the line RX 580 PULSE (20G) model and its NITRO (40G) counterpart: a 40€ premium can't really justify a differentiation in overclocking alone. A similar situation is seen in regards to the RX 570 cards, with a NITRO-branded, 8 GB RX 570 (40G) being priced higher than a 4 GB, PULSE-branded RX 570. Looking at the model numbers, it would seem differentiation between the Polaris 10 chips and the Polaris 20 XTX and XL is done by the last characters in the product number, with the "40G" products carrying a hefty premium over the "20G" parts.

If the PULSE series are based on the Polaris 10 chips, and the NITRO are based on the newer, freshly confirmed Polaris 20 XTX, the expected difference in clock speeds (with overclocked variants of the RX 500 reaching 1500 MHz) and the newer, as-of-yet-unconfirmed LPP fabrication process would go a long way towards justifying such a premium. This could speak for an approach on clock-speeds towards differentiating the multiple RX 580 price-points, akin to the 7970's GHz Edition - likely, top-of-the line Polaris 20 XTX and XL chips will board higher-tier graphics cards, marketed at exceedingly high clock-speeds.

AMD Polaris 20 XTX, XL Chips Powering the RX 500 Series Confirmed

Videocardz has gotten their hands on the launch driver for the RX 500 series of graphics cards, and it would seem that previous rumors have indeed been vindicated: the revised RX 500 series features new code names for the chips that tick at its very heart. The RX 580, according to this report, will feature a Polaris 20 XTX chip (oh ATI X1950 XTX, how I remember you from staring in awe at your price and performance in computer magazines...), while the Radeon RX 570 will be equipped with a Polaris 20 XL part. And while the RX 560 is lacking from the list, the little chip-that-probably-will, the Polaris 12, makes a cameo under the RX 550 series and a "Lexa Pro" GPU code name... Which is just so different from all others, both in form and content, that one must wonder where it is its real name or a simple placeholder.

PowerColor RX 580 Red Devil Golden Sample Pictured With 6-pin, 8-pin Connectors

Remember that PowerColor Red Devil teaser from a few days back? While the source link is no longer available, it would seem that someone has gotten their hands on a (golden) sample, one of the two different SKUs that PowerColor is expected to launch around the RX 580. This Golden Sample edition sports a beefier, higher-performing 2.5-slot cooling solution, compared to the expected RX 580 Red Devil's 2.0-slot one. This sample, however, sports something unusual for a card with the power envelope expected from the RX 580: two auxiliary power cables, one 6-pin, as is par of the course with previous-generation RX 480 cards of which the RX 580 is a rebrand; and another, 8-pin one.

AMD's RX 580, 570 and RX 550 Specifications and 3D Mark Results Leak

So, it would appear that rumors and leaks about the RX 500 series being simple rebrands of AMD's RX 400 line were true. Recent leaks point to no more changes and performance increases than those achieved through higher base clock speeds on the graphics cards' GPU and memory. The architecture is the same, and the process seems to have followed the same path - as of yet, no confirmation regarding whether or not these cards do use a newer, leaner LPP process for higher clocks and less power consumption.

PowerColor Teases New Red Devil Graphics Card - Probably RX 580

PowerColor has pulled some images out of its teaser hat, bringing us some classy, though ultimately uninformative pics of an upcoming Red Devil card. The details that can be gleaned point to a dual-fan design and some semblance of LED illumination (which should always be expected in any recent product launch).

Though we can't know for sure what graphics card this Red Devil tease refers to, logic would dictate that it's the best-performing, upcoming card that we know off. Pulling a publicity stunt for the second-fastest card to arrive (RX 570) just wouldn't make sense, and the timing puts this teaser much closer to (what is expected to be) the rebranded RX 500 line than to the much-awaited RX Vega line of graphics cards. The latter will probably drop in around the same time as Arkane's Prey, which launches on the fifth of May.
