TUL Corporation, a leading and innovative manufacturer of AMD graphic cards since 1997, has added a new PowerColor Red Devil Golden Sample RX 580 8GB GDDR5 and Red Devil RX 580 8GB GDDR5 in the Devil series. It is powered by AMD's 4th generation GCN 4 architecture featuring asynchronous shaders. The PowerColor RX 580 is designed for more smooth game playing and video performance in the latest DirectX 12 and Vulkan, and AAA game titles.

Both PowerColor Red Devil Golden Sample RX 580 and Red Devil RX 580 utilize 8GB of GDDR5 memory with 2304 stream processors and have 2000 MHz memory clock speed which is connected via a new high speed 256-bit memory interface. They have the capability to switch from Ultra Overclocking to Silent Overclocking or vice versa for choosing the BIOS fitting your need, faster clocks or more balanced overclock with quiet operation. On the OC BIOS, Red Devil Golden Sample RX 580 ships with 1425 MHz core clock speed and on the other hand Red Devil RX 580's core clock speed is 1380 MHz. On the Silent BIOS, Red Devil Golden Sample RX 580's core clock is 1411 MHz and Red Devil RX580 is 1355 MHz.

AMD today announced the Radeon RX 500 series graphics cards. The lineup is based on a "refined" variants of the "Polaris" family of GPUs that power the RX 400 series. These include manufacturing-level refinements on the 14 nm FinFET process, which enable higher clock speeds; lower idle and multi-monitor power draw, and a host of software features. The lineup consists of four SKUs, beginning with the Radeon RX 550 at a sub-$79 price point, followed by the Radeon RX 560, which succeeds the RX 460 at $99; the RX 570, which starts at $169, and the RX 580, which is priced at $199 for the 4 GB variant, and $229 for the 8 GB variant.

The RX 580 and RX 570 are based on the 14 nm "Lexa" Polaris20 silicon. This chip is nearly identical to the "Ellesmere" Polaris10, except for the manufacturing-level improvements that enable higher clock speeds. The RX 580 features 2,304 stream processors across 36 compute units, 144 TMUs, 32 ROPs, and 8 GB or 4 GB of GDDR5 memory across a 256-bit wide memory interface. The core is clocked at 1257 MHz, with 1340 MHz boost, and 8.00 GHz (GDDR5-effective) memory. The RX 570, on the other hand, features 2,048 stream processors across 32 compute units, 128 TMUs, 32 ROPs, and clock speeds of 1168 MHz core, 1244 MHz boost, and slightly faster 7.00 GHz (GDDR5-effective) memory. Although available in 4 GB and 8 GB variants, 8 GB appears to be the most common memory amount for the RX 580, and 4 GB for the RX 570.

Marketing rebranded cards is a much greater effort than selling the achievements and improvements of a fully new product launch. And word on the street is AIB partners that have to deal with rebrands don't really enjoy doing so. Having to sell the old as new is a tough sell, especially so when virtually no extra features seem to have been implemented. AMD itself is marketing their new RX 500 series as worthy improvements to its R9 390 graphics cards, for what it's worth. And as such, AIB's have to come up with original, out-of-the-box ways of peddling what is pretty much their old stuff as if it was new.

Recently, we've seen MSI showcasing a "3rd Gen FinFet 14" production process for its RX 570 Gaming X; now, PowerColor is looking to increase the attractiveness factor on its RX 580 Red Devil and Red Devil Golden Sample graphics cards (of which we've seen a teaser here and there) by showcasing an improved, reinforced VRM design for its upcoming graphics cards, with a "Platinum Power Kit", which includes Dr.Mos and a top-of-the-line Digital Power delivery system. Its VRM, however, keeps the 6-phase design that was already present on the RX 480. Here's hoping that the additions to PwerColor's card, alongside the Red Devil's purported 8+6-pin power delivery, will allow for higher overclocks, perhaps making this card a prime candidate for more efficient, exotic cooling solutions.

Some photos, screenshots and benchmarks of what appears to be an XFX RX 580 graphics card are doing the rounds, courtesy of overclocker Lau Kin Lam, who shared them (alongside a three-hour log video) on his Facebook page. Apparently, this is a special, China-only edition of the card, which is a shame, considering the great-looking waterblock that is smiling for the camera. The fact that this card is using a reference board with one 8-pin power connector may prove relevant to its overclocking efforts (and those of other, non-reference boards that we've seen carry both the 8-pin and an extra 6-pin power connector.

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.)

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.

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.

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.

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 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.
