Intel Core 2 Duo: affordable and powerful
Situation with Core 2 Duo processors makes no difference from what was
before. The reviews and test configurations mention primarily the
higher-end and extreme models, whereas the lower-end either get
obnubilated or are lost in the whole mass of all novelties emerging
onto the market and thus become forgotten undeservedly. But it is just
they which are in facts the winners and which will gain most of the
money, however trivial it may sound.
In our materials, we have given a quite detailed account of
the architectural traits of Intel Core and conducted a large number of
tests - from running new processors with math suites up to Core 2 Duo
performance in the most favorite gaming tests. Today we using these
tests to benchmark the most affordable Core 2 Duo processors based on
the Allendale core. As may know, the major and only distinction (of
course, apart from the clock speed) of the lower-end series from the
Conroe processors is just in the twofold reduction of the L2 cache
memory size (to 2 MB). In fact, running a bit ahead, we'd like to note
that it hasn't much influenced the performance, which we'll prove
today.
Note that we are not taking into account another
representative of the series – Core 2 Duo E4300 which, apart
from the remaining aspects, has undergone reduction in the system bus
speed to 800 MHz. We'll be able to talk about the performance of this
processor only after its announcement which, according to the latest
information, is to be held in January 2007.
Intel Core 2 Duo E6300 and E6400 – "a sweet couple"
Currently, the prices for Intel Core 2 Duo E6300 and E6400
processors fluctuate within 200$ to 230$, respectively. That means
their direct competitors are dual-core AMD Athlon X2 3800+ and 4000+
and, to some extent, their brother Intel Pentium D 945 of 3.4 GHz clock
speed. The scattering of prices at distribitors' is wide enough, so
let's at least schematically list the above models of the same pricing
category.
Much has already been spoken regarding the success of Intel's
new architecture. If you are still unaware, you can go deep into
examining the articles «Core
2 Duo processors: shock and awe» and «Dual-core
Intel Conroe processors». Our goal today is
different – to explore the behavior of processors in
practice, reveal their overclocking capabilities in conditions
demanding for overclocking (to be told later), as well as compare the
performance of Core 2 Duo Conroe versus the immediate contenders.
That's just what we'll be doing today, but for now let's look at the
summary table of specifications.

This table is a proof of our words – the differences
among the processors are minimum, and the thrifty user can make up for
the clock speed difference through overclocking. Now let's take a
closer look at the processors.
By sight, the boxed versions of processors make no difference
from one another. Here are two Allendale and one Conroe (Core 2 Duo
E6600) processors.
As compared to Pentium D, the form factor of the box has not
changed - only the color spectrum and positioning of some components
has been changed.
The package bundle is also standard enough. It is the
customary Intel's boxed cooler with factory-applied "chewing gum" and a
list of operating instructions describing the main rules of using the
processor: «Do not chew, do not throw, never heat up in a
microwave, and so on
