AMD’s Rumored Radeon RX 6900 XT May Have 16GB of VRAM

AMD's next-generation Radeon RX graphics, which will use the company's upcoming RDNA 2 microarchitecture, could be ready to take on Nvidia's best Ampere-based GeForce GPUs. It was recently announced that AMD's flagship desktop graphics, codenamed Navi 21, can ship with 16GB of video RAM, while a second high-end model, codenamed Navi 22, can have 12GB of storage.

The memory specifications for the cards are provided by the Twitter user @_rogame. The RDNA 2 microarchitecture from AMD is also known as Navi 2x or colloquially as Big Navi and promises a performance increase of 50% compared to the first generation RDNA architecture.

For comparison: The first-class GeForce RTX 3090 from Nvidia comes with 24 GB of VRAM, while the flagship RTX 3080 comes with only 10 GB of memory. Thanks to the faster GDDR6X memory standard, available exclusively for Nvidia, and a 320-bit bus, the company was still able to achieve a bandwidth of 760 Gbps with the GeForce RTX 3080. With 16 GB of RAM, the AMD card is still available and would come with 60% more memory than Nvidia's flagship.

While AMD has dropped evidence that its new line of graphics cards would be branded as the "6000 Series," it was recently believed that the high-end card with 16GB of VRAM would be called the Radeon RX 6900 XT. However, the exact naming is not confirmed.

AMD has an event scheduled on October 28th to showcase its new RDNA 2 architecture. So we shouldn't have to wait any longer.

More recently, the company unveiled a render of its GPU that shows a metal-cased card with a triple fan. Unlike Nvidia, which removed its Team Green RGB lights in favor of mature, nifty white backlighting, AMD may stick to a gaming-forward design with red accents, sharp angles, and a stylized “R” on the fan around its Radeon to represent branding.

And while Nvidia had switched to a 12-pin low-profile connector for reasons of space, the new Radeon cards appear to use two eight-pin connectors for power supply.

Game Debate also released a second leaked image of the upcoming AMD 6000-series card, revealing a slightly smaller footprint and dual-fan design. This smaller card could represent the 12GB model, suggesting that the larger card could be positioned to accommodate Nvidia's triple-slot GeForce RTX 3090. The smaller card could be branded as the Radeon RX 6700 XT at launch.

Compared to Nvidia's flagship GeForce RTX 3080, however, AMD's memory advantage may not last long. It is rumored that Nvidia is working on a future version of the GeForce RTX 3080 with up to 20 GB of video memory.

In the top area, Nvidia could further expand its advantage over AMD with a new high-end titanium RTX card based on the latest Ampere architecture. This card could hit the market with a whopping 48GB of storage in 2021, according to Moore's Law is Dead YouTube channel reported by Tom's Guide. This card is likely aimed at professionals and creatives rather than gamers, however, and could cost a reasonable amount more than the $ 1,4999 RTX 3090.
