AMD Radeon RX 6000 series GPUs

Rumor: AMD Big Navi RX 6000 GPU memory specs have been reportedly leaked, having 16 GB & 12 GB VRAM

It appears that some alleged specifications for AMD’s RX 6000 RDNA 2-based graphics cards have been leaked by Twitter user @Rogame, who has a strong track record of leaks in the past. But since AMD has not yet confirmed these specs you should treat this leak as a rumor, at least for the time being.

We already know AMD’s next-generation Navi 2x RDNA 2 lineup of GPUs would initially come in two flavors, with two chips having different memory configurations, which are NAVI 21 and NAVI 22, respectively. Navi 21 would likely house the Big Navi RX 6900 XT flagship GPU, which AMD has teased before, whereas the Navi 22 chip will likely land up in the Radeon RX 6700 XT or RX 6800 XT series of cards, successor to the RX 5700 XT GPU.

@Rogame has leaked the memory specs of at least two Navi 2x GPUs based on the new RDNA 2 architecture, which are Navi 21 and Navi 22, respectively. Coming to the VRAM configuration, Navi 21 will feature 16 GB VRAM, and Navi 22 will sport 12 GB of VRAM.

One photo of an alleged RDNA2 engineering sample GPU was already leaked before which featured 16 GB of Samsung’s GDDR6 memory across a 256-bit wide bus interface. We presume this GPU to be the Navi 21 RX 6900 XT GPU. So @Rogame’s 16 GB of VRAM prediction does indeed make sense in this context. The second variant, Navi 22 GPU, will likely feature 12 GB of VRAM across a 192-bit bus interface. As mentioned before, the Navi 22 chip will be featured in the Radeon RX 6700 XT or RX 6800 XT series of cards.

Though, the leaker mentions that he is not sure whether these two Navi 2x GPU variants are based on the full Navi 21/22 GPU die, or they are just cut-down SKUs. The low Memory bus interface on these flagship cards seems a bit odd, but there’s also a possibility that these are just early engineering factory samples.

16 GB and 12 GB VRAM configuration is also possible with 512-bit and 384-bit bus interface, so we can expect AMD to follow this route as well, as there are more options available.

We’ve heard numerous rumors about the Big Navi GPUs these past few weeks. Some early synthetic benchmarks were supposedly leaked; however, we don’t consider them that trustworthy. On the other hand, there are reports that AMD may possibly adopt the USB-C connector interface for select Big Navi 21 Radeon GPUs.

We have also seen pictures of AMD’s Radeon RX 6000 RDNA2 GPU before, showing triple-fan and dual-fan designs. The triple fan variant would most probably be launched as the RX 6900 series, whereas the dual-fan model might house the RX 6800 or 6700 series family. The dual-fan version also features two 8-pin PCIe power connectors.

It will be interesting to see whether the new RDNA 2 will be able to compete with NVIDIA’s high-end RTX 3090/3080, or its mid-tier brother, the RTX 3070. AMD will officially reveal these new GPUs on October 28th. We expect the RX 6000 series to officially debut in November.

Stay tuned for more!

Hello, my name is NICK Richardson. I'm an avid PC and tech fan since the good old days of RIVA TNT2, and 3DFX interactive "Voodoo" gaming cards. I love playing mostly First-person shooters, and I'm a die-hard fan of this FPS genre, since the good 'old Doom and Wolfenstein days. MUSIC has always been my passion/roots, but I started gaming "casually" when I was young on Nvidia's GeForce3 series of cards. I'm by no means an avid or a hardcore gamer though, but I just love stuff related to the PC, Games, and technology in general. I've been involved with many indie Metal bands worldwide, and have helped them promote their albums in record labels. I'm a very broad-minded down to earth guy. MUSIC is my inner expression, and soul. Contact: Email
