Celeron and Xeon: Intel Aims At The High/Low End
At the end of the 1990s, Intel launched two of its best-known processor brands: Celeron and Xeon. The former was aimed at the budget market and the latter at servers, and sometimes workstations. The first Celeron (Covington) was a Pentium II without a Level 2 cache, and suffered extremely poor performance, whereas the Pentium II Xeon had a large cache. Even now, both brands still exist—Celeron for the entry-level market (generally with a reduced cache and a slower FSB) and Xeon for servers (with a fast FSB, sometimes more cache, and high clock speeds).
Intel quickly added a cache to the Celeron with the Mendocino model (128 KB). The Celeron 300A is famous for its overclocking capacities, able to go 50% or more above its rated clock speed much of the time.
|Code name||Covington, Mendocino||Drake|
|Architecture||32 bits||32 bits|
|Data bus||64 bits||64 bits|
|Address bus||32 bits||36 bits|
|Maximum memory||4 GB||64 GB|
|L1 cache||16 KB + 16 KB||16 KB + 16 KB|
|L2 cache||0 KB/128 KB (internal, CPU frequency)||external, 512 KB-2,408 KB (CPU frequency)|
|Clock frequency||266-300 MHz/300-533 MHz||400-450 MHz|
|FSB||66 MHz||100 MHz|
|FPU||built in||built in|
|Fabrication process||250 nm||250 nm|
|Number of transistors||7,500,000/19,000,000||7,500,000 + cache|
|Power consumption||16–28 W||30-46 W|
|Voltage||2 V||2 V|
|Die surface area||131 mm²/154 mm²||131 mm² + cache|
|Connector||Slot1/Socket 370 PPGA||Slot 2|
Like the Pentium II, Xeon had an external L2 cache inside the processor cartridge. Its capacity was between 512 KB and 2 MB, and the number of transistors between 31 million and 124 million.

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
