Alleged Radeon RX 6000 GPU sample spotted – Is this AMD’s Big Navi?

The leaker of this image has stated that this graphics card uses eight GDDR6 memory chips, which gives this graphics card 16GB of GDDR6 memory over a 256-bit memory bus. This implies that this graphics card is not AMD’s flagship “Big Navi” graphics chip; unless AMD has found a way to significantly increase its effective memory bandwidth without using a wider memory bus. 

This graphics card is an engineering sample and will look nothing like AMD’s final retail products. Sadly, there is little information to be gleaned from these images, as they give us little to no information about AMD’s future products and aspects of the graphics card like PCIe power connections are often over-built on engineering samples for testing purposes.   
 
AMD is due to launch its RDNA 2 architecture on October 28th, with AMD promising “a breakthrough gaming architecture”. Gamers should expect a huge performance leap over today’s RDNA-based products, though it remains to be seen how AMD’s new products will compare with Nvidia’s new Ampere offerings.
