The front runners of the computer community including wealthy computer enthusiasts are all impatiently waiting for the Bloomfield processors from Core i7 family to come out. Intel understands this situation very well that is why they haven’t released any new Core 2 Extreme processors for a while now: they could hardly interest potential customers who were expecting something completely different from the processor leader – new-generation solutions on Nehalem microarchitecture.

At the same time, more thriftful users who usually buy solutions with reasonable price-to-performance ratio, express purely theoretical interest to upcoming launches. The relatively inexpensive new-generation processors aka Lynnfield and Havendale should start selling in H2 2009 the earliest. Therefore, Intel continues to refresh the mainstream processor segment with new Wolfdale CPUs based on the latest 45nm second generation core with Core microarchitecture.

Following the launch of a pretty expensive Core 2 Duo E8600, the company released two simpler CPUs: Core 2 Duo E7300 and Pentium Dual-Core E5200. These processors are priced very affordably at $133 and $84 respectively; therefore, they will most likely be of great interest to many users out there. The first one expands E7000 processor family that includes CPUs with L2 cache memory reduced to 3MB. As you know, E7000 series came to replace E4000 series that included processors on 65nm Allendale core (Conroe variation). The second new CPU, Pentium Dual-Core E5200, brings to a new level the features of a reanimated Pentium family that has become a transitional stage between Core 2 Duo and Celeron families. So, the launch of Pentium E5200 retires all the previous Pentium Dual-Core E2000 models based on a cut-down Allendale core.

As a result, old 65nm cores remain only in the cheapest Celeron processors, because Intel hasn’t yet introduced a 45nm replacement for them. In all other market segments, older 65nm CPUs have more up-to-date analogues manufactured with finer 45nm process. We tried to illustrate this evolutionary process with the following table:

However, old 65nm processors from E4000 and E2000 series will not disappear from the stores until Q1 2009, although there will definitely be fewer of them available.

Nevertheless, the table above shows very clearly that new processor models are evidently superior to their predecessors in terms of features and functionality. Therefore, no wonder that 45nm CPUs will be preferable for a mainstream computer system. Our today’s review should back these statements up with some practical data. We are going to focus on two new processors, Core 2 Duo E7300 and Pentium Dual-Core E5200. So, today we will deal with inexpensive dual-core processors with models numbers ranging from E1000 to E7000 and price within $80-$140 interval.
