AMD may refuse the use of HBM memory because of the high cost and technical complexity .
Answers to many questions gives the publication on the site PC Perspective, which is dedicated to all of the same theme - the opening graphics architecture Polaris, which this year will present the life of graphics solutions Arctic Islands. Speaking about the factors that ensure a marked reduction in the area of the GPU compared to 28-nm products, AMD representatives explain that it is 70% due to the use of 14-nm process technology with FinFET-structures, and the remaining 30% - the work of builders to optimize the design of the graphic processor.
AMD's open-slide also results comparing the energy consumption level of GeForce GTX 950 and the price of a comparable graphic solutions new generation architecture Polaris. By the way, the test specimen has an age of not more than two months, and for this period of life cycle it performs quite well. With an equal performance level AMD is much more economical, consuming 86 watts versus 140 watts for GeForce GTX 950 in one of the modern games. The graphics processor used by this model, released on 14 nm technology by GlobalFoundries company.
So, according to Macri, a move to FinFET will provide a speed increase by 25-30% at constant energy consumption, a reduction in energy consumption by 50-60% at constant speed compared to 28-nm graphics solutions. Rather, AMD will use two features: lift, and performance, and slightly reduce the power consumption. Is it possible to pull out of this proportion promised twofold improvement in energy efficiency, we will know closer to the middle of the year, when there will be representatives of the serial architecture Polaris.
As for the possibility of further use of memory type HBM AMD representatives say: "The company has invested in the development of this memory type , and it continues to be in the road map." That is, AMD reserves the right to use HBM in all its future cards. Related Products :
