The launch of Intel processors based on Core microarchitecture turned into a truly revolutionary event. These processors appeared a very successful solution for the desktop market, especially against the background of their predecessors: Pentium 4 and Pentium D CPUs based on NetBurst microarchitecture. Core 2 Duo processors for desktop PCs turned out not only faster but also much more economical than Pentium 4 and Pentium D solutions.
I believe it won’t be an exaggeration if I say that Core microarchitecture proved a powerful breakthrough that turned NetBurst based CPUs into the least competitive offer almost instantly, at least in the upper price range. Moreover, Intel Core 2 Duo processors became an excellent argument in the eternal rivalry with AMD, which Athlon 64 and Athlon 64 X2 processor families have been offering the best consumer features for a few years running. In other words, Intel Core microarchitecture became a significant milestone for the desktop segment, and the first CPUs based on it have changed the situation in the market radically. According to the result of numerous independent test sessions performed on Intel new processors, Core 2 Duo is undoubtedly the today’s fastest desktop CPU, which is also offering the best performance-to-power consumption ratio.
Our site has already paid a lot of attention to CPUs on Core microarchitecture designed for desktop platforms. However, it is important to mention once again that one of the greatest advantages of this microarchitecture specifically stressed at launch is its universality. The developers’ concept implies that the CPUs based on practically the same core with new microarchitecture inside should undergo very minor modifications in order to be suitable not only for desktop systems, but also for servers and mobile PCs.
Core architecture owes its superb flexibility to the opportunity to vary the maximum frequency and power consumption in relatively broad ranges. In other words, if the working frequency of CPUs with Core microarchitecture is lower than that of desktop CPUs, these processors can suit perfectly for economical mobile systems. So, our today’s article will be devoted to this particular application field.
So, today we are going to talk about mobile processors on Core microarchitecture also known as Merom and about mobile platforms built around them. I would like to point out that looking at Core microarchitecture from a new angle is more likely to give fresh food for thought than another desktop CPU review. The thing is that Merom processors came to replace Core Duo family (also known as Yonah), which were not based on NetBurst microarchitecture. Therefore, it would be incorrect to claim that we already know the outcome of the Core Duo against Core 2 Duo duel. Yonah CPUs feature their own mobile microarchitecture, with a few allowances they can be characterized as dual-core CPUs based on Pentium M that borrowed their microarchitecture from Pentium III. As for Core processors (Conroe, Merom and Woodcrest), they can be regarded as a further development of Yonah. In other words, mobile Core Duo and Core 2 Duo are close relatives, and it is really interesting to compare them against one another from both: theoretical and practical prospective. So, let’s get started!
