Pentium M: Laptops Flex Their Muscles
In 2003 the market for portable PCs was booming and Intel had only two processors for them: the aging Pentium III Tualatin and the Pentium 4, whose high power consumption made it unsuitable. But a savior was to arrive from Israel: the Banias (alias Pentium M). This processor, based on the P6 architecture (the same as the Pentium Pro) had high performance and low power consumption. It even beat the Pentium 4, while consuming a lot less power. This was the processor used in the Centrino platform and it was quickly followed (in 2004) by the (faster) Dothan model. The Pentium M left its mark on the world of mobility, and the Stealey (A100) still uses the Dothan architecture (with lower frequencies and TDP).

As with the Pentium 4, the FSB actually operated at a quarter of the nominal frequency (QDR). The connector used, the Socket 479, actually had 478 pins, but they were arranged differently from the Pentium 4 Socket 478 (though adapters were made).

great article with only a few slight errors (like saying the core2duo has 1-4 cores... i don't think there's a 1 cored version lol)Reply
Looking forward to the AMD article.
To correct you. Core 2 Duo has ONLY 2 cores, not more, not less.Reply
Core 2 Quad, has 4 cores and Core Solo has 1 core.
Yes there is a singal core,
Ok it is not under the same branding but it is part of the same microarchitecture
I might be wrong, but i resemble that the Pentium 166 (32bits adress bus and all) had support for 4Gb of memory. I remember IBM sold it's top line (at that time) with 64Mb support (even with SDR PC100/66 support). Correct me if i'm wrong please.Reply
The core 2 does supply 1-4 cores - 2 cores per die, where one might be disabled, and one or two dies on a socket. It's no less right to call a core2duo a cpu with 1-4 cores, than it is to put the pentium d on the same page as a single core prescot, as it's the very same principle.Reply
Arkzgreat article with only a few slight errors (like saying the core2duo has 1-4 cores http://en.wikipedia.org/wiki/Coree ... i don't think there's a 1 cored version lol)Looking forward to the AMD article.Reply
Thanks for the heads-up! I tweaked that passage to better represent the Core 2 architecture's available configurations!
vosesterOk it is not under the same branding but it is part of the same microarchitecture Exactly. The article says:Reply
ArticleThere are many versions of the architecture, resulting in configurations with a different number of cores
There is no mention of the branding, so there is no actual error there, just misinterpretation.

Yes, it isn't called a "Core 2 Duo," but it uses the Core architecture and only has a single core enabled.
But I will have to say, there aren't any 3 core models...
Good to hear you're not only doing an AMD article, but an ATI one as well (in response to the Nvidia article you did earlier, assuming). A sign of class from the new Tom's is a welcome one.Reply
I wish they would get rid of those stupid SNAP Linkbubless and Inteltex misguiding links. Who ever invented those stupid annoying double lined text popups should have been burned at the stakeReply
