Of course, the decoding tasks that happen during a transcode travel down the same fixed-function pipeline already discussed, so there’s additional performance gained there. There’s a media sampler block attached to the EUs (Intel calls this a co-processor) that handles motion estimation, augmenting the programmable logic. On the encode side, you have fixed-function logic working in concert with the programmable execution units. Video scaling, denoise filtering, deinterlacing, skin tone enhancement, color control, contrast enhancement-all of those capabilities are addressed by blocks of logic in the graphics engine. ![]() It also adds MVC support, enabling Blu-ray 3D playback, too. Sandy Bridge rectifies this by moving the complete decode pipeline to an efficient fixed-function multi-format codec. However, motion compensation (the most complex piece of the decode pipeline) and loop filtering (applicable to VC-1 and AVC) have to be handled by the general-purpose execution units, eating up more power than necessary. Intel already had a strong position on the decode front-its existing graphics-equipped processors are able to handle MPEG-2, VC-1, and AVC. There are two encompassing ideas here: encode and decode. It’s like AMD with Eyefinity in that way-Intel took a major leap on the down-low, a number of ISVs were willing to play ball, seeing value added to their own products, and now the company has a major competitive advantage that’ll take a comparable effort to match. But everything I’m hearing puts both companies a year away from having something able to compete. Needless to say, once word of Quick Sync spread, both AMD and Nvidia started burning rubber right away, working on their own answers to the fixed-function hardware built onto Sandy Bridge-based processors. The investment into Quick Sync ends up going a lot further than a more modest gain in 3D alacrity. Of course, it helps that video is one of Intel’s competencies. Intel is quite literally betting precious die space that video applies to a broader range of its customers than if it burnt transistor budget on more gaming performance. Hong Jiang, the senior principle engineer and chief media architect of Sandy Bridge, this decision was based on the pervasiveness of video. Intel’s answer was to build a dedicated block of silicon onto Sandy Bridge-based processor that does nothing but video.
