Made on a 14nm process, about half of the Broadwell-U lineup packs 1.3 billion transistors in a 82mm² die. The larger version, which is pictured below, is used by the models with Intel HD Graphics 6000 or Iris Graphics 6100, which promises significantly better integrated graphics thanks to having twice as much execution units as the smaller version. These Broadwell-U cores have 1.9 billion transistors and a 133mm² die size. A full list of the specifications of each chip can be found in Intel's spec sheet (PDF).
Additionally, Intel also started shipping its 14nm "Cherry Trail" tablet chip which is based on the same architecture as the Broadwell-U.
Today, Intel unveiled the 5th Generation Intel® Core™ processor family. Built on Intel’s cutting edge 14nm manufacturing process, the 5th Gen Intel Core processors deliver premium performance, stunning visuals and enables improved battery life to take computing to the next level. The performance also provides the foundation for more natural and interactive experiences with Intel® RealSense™ technology, Intel® Wireless Display (Intel® WiDi) and voice assistants. With the “Broadwell” microarchitecture expected to be the fastest mobile transition in company history, offering consumers a broad selection and availability of devices, the 5th Gen Intel Core processors are purpose-built for the next generation of compute devices offering a thin, light and more efficient experience across traditional notebooks, 2 in 1s, Ultrabook™ devices, Chromebooks, All-In-One desktop PCs and mini PCs.
Key benefits of the 5th Generation Intel Core family and the next-generation 14nm processor for tablets include:
Powerful Performance. The 5th Generation Intel Core (U series) processors utilize Intel’s new 14nm process technology to improve upon the previous generation Intel Core processor’s success with 35 percent more transistors on a 37 percent smaller die. The new process, combined with architectural enhancements, enables the 5th Generation Intel Core processors to deliver up to 24 percent better graphics performance, up to 50 percent faster video conversion and battery life that is up to 1.5 hours longer1 . Consumers who are planning to refresh a 4-5-year-old PC will also notice significant improvements: graphics performance up to 12 times better, video conversion speed up to 8 times faster, productivity performance up to 2.5 times faster, wake times 9 times faster, all with up to 2 times longer battery life2
Power Efficient. Even Longer Battery Life. Intel continues to drive battery life improvements, and the newest processor family raises the bar yet again. With power management and design improvements, plus the increased efficiency of Intel’s 14nm manufacturing process, consumers get up to 1.5 hours more battery life3 than the previous 4th Generation Intel Core (U series) processors. The result is more power and performance without sacrificing battery life.
Watch. Game. Create with Intel Graphics. The 5th Generation Intel Core processor family brings the next evolution in processor graphics architecture enabling new levels of performance and power efficiency paired with Intel’s leading CPU technology. The new 5th Generation Intel Core processor family offers graphics options including Intel® HD Graphics 5500, HD Graphics 6000 and Intel® Iris™ Graphics 6100. All of these provide stunning visuals and enable 4K Ultra HD display, including over Intel WiDi 5.14 . Additional platform features include enhanced new codec decode support for VP8, VP9 and HEVC, as well as support for the latest graphics APIs (DX 11.2, DX 12 Ready) and graphics programmability features, including OpenCL 2.0 and OpenGL 4.3. Intel Iris Graphics includes these features plus significantly better 3D performance compared to Intel HD Graphics 5500 processors. Whether playing the latest mainstream game, watching videos in 4K Ultra HD, or simply sharing your latest gameplay and video creations with family, Intel HD and Iris graphics deliver an eye-popping visual experience.
Intel also started shipping its next generation 14nm processor for tablets, codenamed “Cherry Trail”. The new system on a chip will offer new user experiences such as Intel® RealSense™ technology, no wires, no password and Intel® Context Aware™ technology capabilities. New products based on “Cherry Trail” will be introduced starting in the first half of 2015.
