1 higher gross margin from higher ccg platform revenue was driven by higher average selling prices on notebook and desktop platforms , offset by lower desktop and notebook platform unit sales . 2 lower gross margin from lower ccg platform revenue was driven by lower desktop and notebook platform unit sales , partially offset by higher average selling prices on desktop , notebook , and tablet platforms . data center group segment product overview the dcg operating segment offers platforms designed to provide leading energy-efficient performance for all server , network , and storage applications . in addition , dcg focuses on lowering the total cost of ownership on other specific workload- optimizations for the enterprise , cloud service providers , and communications service provider market segments . in 2016 , we launched the following platforms with an array of functionalities and advancements : 2022 intel ae xeon ae processor e5 v4 family , the foundation for high performing clouds and delivers energy-efficient performance for server , network , and storage workloads . 2022 intel xeon processor e7 v4 family , targeted at platforms requiring four or more cpus ; this processor family delivers high performance and is optimized for real-time analytics and in-memory computing , along with industry-leading reliability , availability , and serviceability . 2022 intel ae xeon phi 2122 product family , formerly code-named knights landing , with up to 72 high-performance intel processor cores , integrated memory and fabric , and a common software programming model with intel xeon processors . the intel xeon phi product family is designed for highly parallel compute and memory bandwidth-intensive workloads . intel xeon phi processors are positioned to increase the performance of supercomputers , enabling trillions of calculations per second , and to address emerging data analytics and artificial intelligence solutions . in 2017 , we expect to release our next generation of intel xeon processors for compute , storage , and network ; a next-generation intel xeon phi processor optimized for deep learning ; and a suite of single-socket products , including next-generation intel xeon e3 processors , next-generation intel atom processors , and next-generation intel xeon-d processors for dense solutions. .

operating_income_2016 = 10646
operating_income_2015 = 8166
change = operating_income_2016 - operating_income_2015
percent_change = change / operating_income_2015
answer = percent_change * 100
