The most interesting and exciting topic of the Intel Developer Forum 2012 that kicked off in San Francisco this Tuesday was, of course, the unveiling of the new Haswell microarchitecture, which Intel is going to introduce in the next generation of their processors.

Intel Corporation's chief product officer described how its low-power processors, starting with the company's 4th generation Intel Core processor family available next year, will set a new standard for mobile computing experiences and innovative Ultrabook, convertible and tablet designs.

Intel is working really hard on improving the mobility of the devices with their microarchitecture inside. In his morning keynote presentation Davis (Dadi) Perlmutter dwelled specifically on this particular aspect of the technology evolution. About a decade ago the notebook segment got a big push making ultimate mobility one of the key objectives. However, the demand for mobility today and the extent of its expansion have grown much bigger. But nevertheless it is just the beginning. People are used to using computers as part of their everyday life and want to continue doing so while moving around. They want the opportunity to use the data, watch videos, and run applications without any limitations. So, last year Intel introduced a new device concept - ultrabooks, and a few months ago they rolled out their third-generation core manufactured using 22 nm process. But it doesn’t stop here.

The next generation Haswell microarchitecture based on 22 nm process is coming next year. This microarchitecture was designed with mobility in mind. One of the things they did was cutting 20X off the item power compared to Sandy Bridge 2nd generation core technology. They also designed the new generation microarchitecture taking into account advanced power management functionality, frameworks, and the new Windows 8 OS. At the Intel Developer Forum in San Francisco David (Dadi) Perlmutter demonstrated that Intel indeed reduced the platform idle power of its 4th generation Intel Core processor family based on the next-generation "Haswell" microarchitecture by more than 20 times over the 2nd generation while delivering outstanding performance and responsiveness.

Let’s take a closer look at the new upcoming Haswell microarchitecture so that we could get a better idea of what to expect, especially, since there were quite a few deep dive sessions at the forum dedicated to Haswell and the upcoming processors based on it.
