A reference to an unreleased Radeon RX 7900 GRE GPU specced with 16 GB of VRAM appeared on distributed computing platforms last month. The unusual GRE acronym was a little bit puzzling, but ITHome has recently discovered that this could be the successor to an older GME (Golden Mouse Edition) card. AMD's Radeon RX 590 GME design was released back in March of 2020 to celebrate the year of the Rat or Mouse.

The Chinese zodiac sign for 2023 is the rabbit, hence AMD preparing a Golden Rabbit Edition (GRE) for that territory. ITHome proposes that this Radeon RX 7900 non-XT model could field a cut-down version of Team Red's Navi 31 GPU—with its Compute Unit count possibly reduced slightly below the standard 84 CUs, while an allocation of 16 GB of GDDR6 video memory gets coupled to a 256-bit interface (down from the XT's 20 GB and 320-bit). The short report does not provide any release date information or detailed specifications/features, but we can assume that the GRE is highly likely to arrive within the year it is intended to commemorate.

It's no news that AMD's Radeon RX 570 graphics card is carved out of the same "Polaris 20" silicon as the RX 580, by disabling 4 out of 36 GCN compute units. AMD kicked a controversy recently, when it launched a China-specific Radeon RX 580-branded SKU with the core-configuration of the cheaper RX 570, confusing Chinese consumers. It turns out that this RX 580 2,048 SP SKU is based on the same exact ASIC variant of the "Polaris 20" silicon as the RX 570, with the only difference being device ID.

We watch a lot of GamersNexus content. Our GPU Database curator noticed something interesting in their recent teardown of a Dataland Radeon RX 580 (2,048 SP) graphics card directly imported from China. The unique ASIC sub-variant code etched on the GPU's aluminium reinforcement brace matches that of the RX 570. AMD internally refers to the RX 570 as "Polaris 20 XL," and its ASIC code etched is supposed to be "215-0910052." For the RX 580, the real one, aka "Polaris 20 XTX," the code etched is "215-0910038." Thanks to GamersNexus' high-resolution filming, our curator was able to spot the ASIC code for "Polaris 20 XL" on the Dataland card's GPU. This confirms that AMD merely took an RX 570 and gave it a different device ID to create the RX 580 2,048 SP, leaving consumers to wade through the confusion.

Yeston, the Chinese manufacturer of graphics cards from both NVIDIA and AMD alike, has announced what is one of the (as of yet) few triple-fan takes on the recently-released RX 580 graphics card. Yeston increased the graphics card's footprint by adding that third fan, which partially settles against a protrusion added by the card's backplate.

The center fan is 10 cm wide, while the outer fans are 9 cm - all temperature-level controlled, which means they remain idle until a certain temperature threshold is reached. There is a LED-backlit RX 580 logo on the side of the card, as well as Radeon RX branding on the backplate. The RX 580 GameAce is clocked at 1340 MHz, which probably means a Polaris 20 XTX chip. This model will not be sold outside China, which is a downer, since its cooling system seems interesting enough, and the card is pleasing in aesthetics. However, some of you might find a way to get them shipped to your doorstep if you so wish.

AMD is on a roll with product launches lately, having just pushed out what is probably the most significant update in mainstream CPUs in years: the Ryzen 5 line of desktop processors. You can look over TPU's review of the 1500X and 1600X here and here. AMD is looking towards powering another central part of your desktop processor, though, with the impending launch of the RX 500 line of GPUs.

Confirmed as rebrands of previous-generation Polaris 10, the new RX 500 series will carry the new Polaris 20 XTX and Polaris 20 XL chips, which are expected to feature higher clocks (in the range of 1300-1400 MHz) from AIBs, before your own overclocking. PowerColor has officially confirmed the launch date as April 18th through social media with a tease for their new Red Devil graphics card. Now if only we could see Vega on this new horizon...

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.
