INTEL HAS SILENTLY improved its Core 2 Duo line-up.
The company recently issued a paper (PCN 106853-00) which calls for a new revision of Conroes that sell under the name Core 2 Duo E6300 and E6400, that is, the entry level models with 2MB of L2 cache.
New revisions are also coming for Xeons 3040 and 3050 and yet unannounced Pentium E4000 series (low-cost CPUs with 800MHz FSB).
Although some might expect that, after B1 and B2 revisions, either a B3 or C2 rev should follow, Intel marked this new revision as L2, probably referring to Low Power 2. The only ways to detect a new revision are either looking for product code SL9TA instead of SL9SA or to look for CPUID marked 6F2 instead of 6F6 - the current ones.
This comes as an answer to AMD's Brisbane processors, which consume only seven and a half watts in idle mode and 65W when fully loaded.
As a contrast, Core 2 Duo eats up 22 Watts while doing nothing and 65W when working under full load. With the new revision, power consumption in idle state (C1E) goes down to 12W. However, the methods Intel and AMD use yo express power consumption are not comparable, because AMD calls for Maximum TDP, while Intel declares Typical TDP.
In the end, both methods are so-so, because the TCO figure will differ by couple of cents of power consumption a year. The switch from 7W to 22W makes a big difference, especially for large organisations that keep their computers running 24x7.
