In the segment of graphics solutions for built-in appliances, AMD has been using the layout that combines on a single printed circuit board graphics processor and memory chips.
As explained by colleagues from the German site ComputerBase.de, at the Hot Chips conference AMD chief engineer products Joe Macri spoke about the long road from the first prototypes to series graphics processor with built-in memory. According to him, the creation of the product, which now bears the symbol of Fiji, took a total of eight and a half years. As soon as united with ATI, s back in 2007 AMD started to work on the integration of memory and the GPU.
First on the same substrate with the CPU adjoined memory chip type DDR3. By 2009, the number of chip-type GDDR3, separating the substrate from the graphics processor, increased to two units. That , early prototypes used the central processing unit for such experiments, as developed in the era of independence, ATI, AMD. The first GPU neighboring the memory became RV365, which was manufactured on 55-nm technology.
By 2011, AMD sat on the total memory support GPU generation Cypress. Gradually growing complexity of graphics processors, and increased area. Active work on the creation of Fiji began in July last year. Crystal area of 592 square millimeters is placed on a silicon substrate area of 1011 square millimeters, near the four memory chips such as HBM. Production of silicon bridge on 45-nm technology company engaged UMC . Related Products :
