management 2019s discussion and analysis of financial condition and results of operations (continued) the following results drove changes in ccg operating income by approximately the amounts indicated:.
| (In Millions) | Operating Income Reconciliation |
| --------- | --------- |
| $10,646 | 2016 CCG Operating Income |
| 1,250 | Lower CCG platform unit cost |
| 905 | Lower CCG operating expense |
| 625 | Higher gross margin from CCG platform revenue<sup>1</sup> |
| (645) | Higher factory start-up costs, primarily driven by the ramp of our 10nm process technology |
| 345 | Other |
| $8,166 | 2015 CCG Operating Income |
| (2,060) | Higher CCG platform unit costs |
| (1,565) | Lower gross margin from CCG platform revenue<sup>2</sup> |
| 435 | Lower factory start-up costs, primarily driven by the ramp of our 14nm process technology |
| 430 | Lower production costs primarily on our 14nm products, treated as period charges in 2014 |
| 375 | Lower operating expense |
| 224 | Other |
| $10,327 | 2014 CCG Operating Income |
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. .
