AMD Navi 21 “Big Navi GPU” For Radeon RX 6000 Series Details Leak Out Indicating Multiple Tiers Of VRAM?

AMD’s next-generation of AMD Radeon RX 6000 Series of Graphics Cards, based on the RDNA 2 (Navi 2X) lineup of GPUs would initially feature two chips. Incidentally, these GPUs will significantly differ from each other in terms of processing capabilities and consequentially, retail pricing. Additionally, the new AMD GPUs will also have vastly different memory configurations.

After NVIDIA announced its latest Ampere-based GeForce RTX 3000 Series of Graphics Cards, AMD appears to be tweaking the configuration of its AMD Radeon RX 6000 Series of Graphics Cards. The pricing of NVIDIA GeForce RTX 3070 and RTX 3080 has clearly posed a challenge to AMD, and hence, the company could be optimizing the specifications and features to offer better products with attractive pricing.

AMD Radeon RX 6000 Series Specifications Leak, Indicating Two Tiers Of GPUs With Varying VRAM Sizes:

Regular tipster Rogame claims to have the final production-ready specifications of the upcoming AMD Radeon RX 6000 Series of Graphics Cards. He claims to confirm the memory configurations of at least two Navi 2X GPUs based on the RDNA 2 architecture. These GPUs include the Navi 21 and Navi 22.

Apparently, AMD’s Navi 21 design, which is based around the “Big Navi” GPU, will power the flagship variants in the Radeon RX 6000 series lineup. Meanwhile, the Navi 22 GPUs will power the high-performance lineup. The Navi 21 GPUs will reportedly pack 16 GB VRAM. Incidentally, a previous leak indicated a “Big Navi” GPU that featured 16 GB of Samsung’s GDDR6 memory across a 256-bit wide bus interface.

The Navi 22 GPU will reportedly pack 12 GB of VRAM. The memory would support the 192-bit bus interface. If the reports are accurate, the Navi 22 GPU would power graphics cards that would succeed the Radeon RX 5700 XT series. It is important to note that the reports haven’t been confirmed by AMD. Moreover, the memory bus interface seems low. Hence, it is still possible that AMD would deploy 16 GB and 12 GB VRAM with 512-bit and 384-bit bus interface.

AMD Radeon RX 6000 Series Specifications, Features:

The flagship Graphics Card in the upcoming AMD Radeon 6000 Series, the AMD Radeon 6900, is reportedly featuring a triple axial-tech fan setup on the shroud and has a large aluminum heatsink that runs beneath it. The card will feature dual 8-pin power and display ports would include a USB Type-C (VirtualLink), 1 HDMI, and 2 DisplayPort connectors.

Moving on to the AMD Radeon RX 6800/6700 Series, these will reportedly have a dual-slot design and a compact form-factor. The cards will feature a dual axial-tech fan design. There are reportedly two 8-pin power connectors on the card but AMD might just deploy an 8+6 or configurations for the more power optimized variants. The ports on the back of the AMD Radeon RX 6800/6700 Series should be similar to the Big Navi graphics card.

AMD Radeon RX 6000 Series Graphics Card Availability and Expected Pricing:

AMD will officially be announcing its Radeon RX 6000 series graphics card family on October 28th. However, there’s no confirmed indication about availability. Meanwhile, NVIDIA GeForce RTX 3000 Series of Graphics Cards are already out. Moreover, their pricing is very aggressive.

Going up against the NVIDIA’s Ampere-based graphics cards, the Big Navi-based AMD Radeon 6000 Series will have to offer a lot of value proposition for the entry-level and budget gamers. This is simply because serious gamers, professionals, and even enthusiasts would prefer the new NVIDIA Ampere Graphics Cards which offer flagship performance at comparatively half the price of last year’s flagship products.
