Alleged AMD Radeon "Big Navi" Prototype Pictured
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.

sounds about right.
Now and if amd is second after nvidia on gpu it's not a shame at all, and still they are more friendlier for the consumer than the others.
Greed is a must for today's standards.
Anyways, the leaker sure could have given hi/her system some TLC. It looks like it's been in a dust storm, who would put such a beast of a card into such a machine? It's a scandal, lol. :laugh:
The only reason they look friendlier to consumer because they don't want to go under by charging consumer less than competitors do.
This did at least generate a lot of talk. Maybe AMD further looking to see what people think?
Weird card...
But then again, a 512bit memory never was never an option, IMO. Too much die space, complicated PCB and high power consumption...
And if it's engineering sample, it may be different than final product.
And how it works... reading comprehension is how it works. If they push straight to 512 bit on this version, they have no headroom to take it a step further. And they'll need to anyway if any catching up is to be done. But yeah, its all guesswork at this point anyway.
But a gap of 256 bit and 512 bit seems pretty excessive for a Navi 20 range, to me. It means one of two things... neither is a great outlook.

And yeah, that leak looks fake as hell.
We were told 8nm Samsung sucks, but it has higher transistor density than 7nm 5700.
