That’s a win on two fronts-if you can afford to throw hardware at the problem. Because they involve fewer transistors, they also use a lot less power. These are faster than parallelized programmable logic (like EUs), which are in turn quicker than general-purpose IA cores. With Broadwell, Intel continues its quest to push more work at the fixed-function blocks optimized for specific tasks. Over time, Quick Sync has evolved to accelerate the latest formats, while giving developers more balance between quality and performance (target usages). The company lobbied ISVs to support its hardware, and a number of apps surfaced right off the bat to exploit it. More than four years ago, it introduced Quick Sync, again leveraging its manufacturing advantage to build a fixed-function engine for media encode/decode acceleration. Intel has a storied history of design decisions rooted in simultaneous performance and power gains.
