The first mention of the graphics card with the symbol Fiji XT appeared in Indian customs . But the second popular source SiSoftware Sandra, in this sense, was more generous.
The card has 4096 stream processors at 1GHz, which are divided into 64 blocks of computing and memory system was organized as unusual for most prospective buyers properly. Apparently, the graphical solutions Fiji will use the memory type HBM, which at modest basic characteristics will provide a phenomenally high throughput.
Memory type HBM involves a multi-tiered (stack) layout. Every gigabyte of memory in a single tier capable of operating at frequencies up to 1.2 GHz, providing a bandwidth of 128 GB / s at 1024 bit bus width. If you combine the four bus, then the output of 4 GB memory with a total width of 4096 bits is 512 GB / s. Sandra database note memory frequency of 1.25 GHz, which increases the theoretical bandwidth up to 533 Gb / s. In fact, it is 66% more than the Radeon R9 290X, and the performance of stream processors Fiji XT Radeon R9 290X exceed 50%. Related Products :
