Information about Intel's next-generation processor architecture, codenamed Haswell, has been leaking steadily for some time, but presentations at today's Intel Developer Forum (IDF) are finally giving us details on what to expect from the fourth-generation Core processors when they launch in 2013.
Haswell is a "tock", in Intel parlance—a completely new processor architecture manufactured using the same 22nm process and "3D" tri-gate transistors as Ivy Bridge. As with Ivy Bridge, the bulk of Intel's attentions are focused on improving graphics performance and reducing power consumption—while Haswell's optimizations will definitely make it faster than Ivy Bridge at the same clock speeds, CPU performance definitely took a back seat during Intel's Haswell-oriented keynote today.
The CPU: modest improvements in a power-efficient package
Much about Haswell's architecture is similar to Ivy Bridge in many ways: key technologies like Turbo Boost and Hyperthreading are still in play, and the instruction pipeline and L1 and L2 cache sizes remain the same.
