This in particular will come with 4GB of GDDR5 memory across a 256 bit interface besides packing an 8+8 power design with 14 Phases on the PWM alone. The PCB images courtesy of OBR Hardware, show us a larger PCB and hence even more polished. You can note the size difference in the image above.
Being a 4GB graphics card, the memory chips have been placed on the back of the card as well that had lead to this variant coming with a Back plate.
