Intel has taken into consideration the needs of enthusiasts and overclockers. Not all improvements cater to the low-power end of the spectrum. Intel calls the new technique SpeedShift, which it says will allow it to switch states more rapidly, providing processing power on demand but also shutting things down with more agility. In another first, Skylake processors will take over the duty of deciding when to switch between power states, which has until now been handled by the operating system. By pushing more instructions through per clock cycle and further reducing occasions when the CPU is waiting for data from a cache or main memory, the CPU can do its work and switch to a lower power state sooner. Intel reminded us that all power savings are the result of better efficiency in the architecture, since Skylake is not based on a new, smaller manufacturing process. Very specific parts of the CPU can be turned off when not required. Beyond that, power gating is even more granular than before. This allows the bulk of the CPU to stay idle while performing an otherwise stressful task, reducing power draw. New formats that can be accelerated include HEVC, AVC, SCc, VP8, and MJPEG. Power reduction has been at the forefront of CPU development for years, and Skylake takes things a step further by dedicating separate fixed-function logic for tasks such as 4K video decoding, streaming, and transcoding. ISP integration reduces the cost and complexity of designing devices, while getting smaller and smaller. Camera capabilities will include face detection and recognition, still capture during video recording, concurrently recording two video streams, zero-lag burst captures, and HDR.

That might seem excessive, but stereo imaging is key to Intel's RealSense efforts.ĤK video recording at 30fps or 1080p at 60fps will be supported. Key amongst these is a camera ISP (Image Signal Processor) that can handle up to four 13-megapixel cameras (but only two simultaneously).

With tablets and other portable form factors in mind, another big change this generation is the incorporation of IO (Input and Output) functionality that has not been integrated into processors before. At the other extreme will be 91W parts, such as the two already launched. At one end of the scale, there will be 4.5W parts for ultralight tablets - these will succeed the current products in the Core M lineup. There is a 20x scale in terms of TDP, which represents power consumption and heat output. It is likely that there will be models that do implement a majority of these features, if not all, but we do not know at this point how Intel will differentiate products at different tiers in its hierarchy.įirst of all, Skylake has been designed with a much wider range of target devices in mind than any previous generation. Diagrams shown do not represent any actual product.
This overview paints a picture of a hypothetical Skylake processor with a superset of all possible features. Over the course of several technical briefings, we were able to build a high-level overview of what Skylake (formally known as the sixth-generation Core architecture) does differently and what users can expect. While details such as speeds and specifications of individual SKUs have not been made public, Intel did share a whole lot of information about the architecture as a whole at the annual Intel Developer Forum this week. The enthusiast-oriented Core i7-6700K and Core i5-6600K are only the tip of the iceberg though Intel will launch many more models across price tiers and device segments over the next year. When Intel launched the first two processors based on the new Skylake architecture at Gamescom a few weeks ago, it didn't share much information about what's new and why they are faster or better than their predecessors.
