We have known for a long time that in 2008 we will see Intel processors on new microarchitecture. We first learned about it two years ago, when Intel introduced their “Tick-Tock” concept, according to which we get new processor manufacturing process or new microarchitecture every year. Last year, Intel introduced Penryn processor family that was a refresh of Core microarchitecture: these CPUs were made with 45nm process using hafnium-based high-k dielectrics. Therefore, this year we should see new Nehalem microarchitecture represented by desktop Bloomfield processors.
Alternating new manufacturing process with the development of new microarchitectures allowed Intel to avoid delays with new processor launches. That is why a year from the announcement of Penryn processors we are ready to talk about processor innovations again: the launch of CPUs with Nehalem microarchitecture is getting closer day by day.
Taking into account how important this event actually is, we decided to split our review of this long-anticipated solution into several parts. Today we are going to talk about the technological and architectural peculiarities of Nehalem microarchitecture and in a few days we will offer you analysis of Nehalem performance in real applications and discussion of its other practical features.
