AMD on CESOfficially revealedIt's a new generation of Vega graphics architecture. Vega card is for high-end market, using the second generation HBM2 memory unit, bandwidth up to 2Gbps/pin, the total bandwidth is still 512GB/s. The size of the AMD display graphics chip is larger than expected, reaching 530 square millimeters, one reason is to join the automatic memory management component called the HBCC cache controller. Other features of the Vega architecture include the highest support for 512TB virtual addressing space, adaptive, fine grained data migration, programmable geometry rendering pipeline. AMD shows BF1, Battlefront graphics operation and Doom game performance, show its performance between GTX 1080 and Titan XP, this result is lower than expected, but the main reason is the driver, Vega is running the Fiji driver, and it uses NCU (next generation computing engine, a single element) great changes with the use of Fiji GCN architecture, so it is necessary to re optimize the driver in order to play the advantages of the new card. 512TB virtual address space to help big data analysis, AMD demonstrated the real-time processing of a log GB data set, if the use of CPU, the size of the data set takes a few hours to render a frame.
