Following Wednesday's announcement of the Radeon RX 6000 series with product launches on October 28, the rumor mill started rolling full steam ahead. The RX 6000 series GPUs by AMD will be based on the RDNA2 graphics architecture, the same exact architecture powering the Xbox Series X and PlayStation 5, and will feature DirectX 12 Ultimate support, including hardware raytracing. A PC enthusiast on Chinese microblogging site Bilibili posted a picture of an alleged "Big Navi" prototype. Since its July 2019 debut, there have been rumors of AMD working on a new high-end GPU to take on the upper-segment of NVIDIA, given that the RX 5700 series offered competitive performance to NVIDIA's breadwinning products, such as the RTX 2070 series and RTX 2060 series.

The picture reveals the reverse side of the alleged "Big Navi" prototype's PCB, showing a larger cluster of GPU ancillaries than those behind a "Navi 10," and eight memory pads with the paper labels "Typical XT ASIC" references for a "16 Gb Samsung GDDR6 memory." Over a 256-bit wide memory interface, the chip should hence have 16 GB of GDDR6 memory. Since this is a prototype, several headers are sticking out of the PCB for the design and prototyping of the product. A tower-type CPU cooler has been MacGyvered onto the GPU (which isn't uncommon for VGA prototypes). We'll hear a lot more about this product in the run up to its October 28 launch.

But how about its POWER CONNECTOR? I need a lots and lots of renders, 'leaked pics' and real pictures by custom cards makers!

No x in gddr6!
GDDR6X is not a JEDEC standard. It's an NVIDIA+Micron exclusive. The only way AMD can match up is the expensive HBM2 MCM route.

256Bit ? so disappointed !

It is too early to conclude if it is just 256 Bit because we don't know if that card in the picture is the top end card. This could well be the direct competitor of the RTX 3070 which also features a 256 Bit memory interface. I feel AMD may also be using the faster 16Gbps GDDR6, instead of the 14Gbps used on the RTX 3070.

Yep...

So... this might even end up no higher than 3070. That's worse than expected. Also, once again you gotta wonder... how the f does this pic exist. Its like my three year old dust bin built up out of second-hand parts from 8 years old. Or is this AMD doing testing in 'real world scenario's' right here? o_O Marketing machine firing on all cilinders clearly

Someone writes 256bit, I saw this, but if it's true I do not know.

Straight to 512 bit? That wipes every chance of a faster version off the table. Seems excessive, but who knows.

16GB,it's not the mid-end card.

If this is indeed the top-end RDNA2 GPU, I can understand why AMD wouldn't want to enter the high-end segment. THEY JUST DON'T SELL. AMD's midrange 5700 series ended up selling way less than Nvidia's high-end, so why would AMD waste their R&D budget for something that they can't sell?
Not to mention the limited producation capacity that could go towards the CPU portion and be way more profitable.
I hope this isn't the top-end chip and AMD can compete with even the 3090, but you can't really expect a 256-bit GPU to be that much faster than a 2080Ti.

One thing for sure is that this ain't a 300W GPU judging from that small cooler.

Straight to 512 bit? That wipes every chance of a faster version off the table.

How does that work ? A wider bus can only mean higher performance not lower.

big navi (navi 21) will have likely 384 bit mem, 24GB, 80 compute units, ~3080 perf?
this is most likely "middle navi" (navi 22) 256 bits mem, 16GB, ~64 compute units -> ~3070 perf?
