compute workloads, including OpenCL. While some gaming workloads are seeing as much as a 3x increase in performance with this configuration when compared to previous-generation Intel® processors, there is potential for performance increases in non-game related tasks. OpenCL applications can take advantage of the heterogeneous computing environment created by the coupled CPU and graphics cores and shared memory architecture to improve performance for applications built with the open standard technology in mind. MEDIA ARCHITECTURE ABOUT THE AUTHOR A contributing writer, roving reporter, podcast host, and blogger for the popular technology site PC Perspective, Ryan Shrout researches and writes product reviews for today's leadingedge hardware and software products. When he's not tracking down the pending changes to the various CPU and computer architectures, Ryan is on tap to assist the RH+M3 group when the need for a hardcore computergeek writer arises. 7 I nte l ® Sof t w are Adren al ine Most of the media capability changes are specification changes, which cover more codecs with accelerated hardware and provide an improved videoprocessing engine. The video codec engine sees additions of MJPEG (often used for web cameras) and scalable video coding (SVC) while improving overall quality for existing codecs, too. Video processing improves with the ability to convert frame rates, and to perform image stabilization on consumer video in real-time. Intel® Quick Sync Video transcoding technology sees improved performance with the GT3 implementations. Support for 4K resolution displays has been added with both DisplayPort 1.2 and HDMI* specifications. For video processing, Intel included accelerated support for functions such as de-noise, skin tone detection, adaptive contrast enhancement, and more. Concurrent video engines will be enabled to allow for higher throughput and better performance (see Figure 5 previous page). This will also result in a lower overall duty cycle and should increase battery life on mobile platforms in the process. Power management will be improved for mobile media consumption with improved power gating on the various "slices" on the GT3. The full GPU doesn't have to be enabled for Intel Quick Sync Video or other video operations if the source doesn't require that much throughput. CONCLUSION The 4th gen Intel Core processor architecture presents a new image of the computer processor. The move to a full SoC has been a long journey but one that is nearing completion with the release of this architecture design. The x86 portion of the architecture sees some of the most dramatic increases in performance and resources in years, while the graphics system will have derivations that basically double available compute power. Power efficiency was a key factor in this generation of processor, driven by the need to find a single architecture in tablets and high-performance computers. The modularity of the CPU modules and the GPU slices are part of that plan, as is support for new lower power sleep states and technologies such as connected standby. Users and developers alike will find the performance improvements impressive while being able to maintain backward compatibility with legacy applications. Intel has much to prove with the 4th gen Intel Core processor architecture, and if early indicators are correct, it will be more successful than any previous offerings.
