ChipWorks Company allowed to look at what looks like a crystal GPU AMD Fiji.
By itself, the GPU Fiji little interest. The chip Fiji was curious to see the memory interface HBM, because it is the first commercial implementation of communication with this type of memory.. When compared to GDDR5 interface, it turns out a slightly larger area in comparison with the 256-bit memory interface GDDR5 4096-bit interface HBM has twice the bandwidth. Definitely - it is a victory.
More interesting than the GPU Fiji, are photographs depicting memory HBM through metallic compounds such as TSVs. . Related Products :
