Celeron with 2.0 GHz in the test: Does a Pentium 4 competitor overclock to 3.0 GHz?

Celeron with 2.0 GHz in the test: Does a Pentium 4 competitor overclock to 3.0 GHz?


What we described events, even if fictional, are not even fetched from that far away. In the history of the Celeron processors, with the exception of the Mendocino Celeron, slimmed-down processor cores of the Pentium were always used. Overall, there were or are sometimes completely different processors that had to listen to the name Celeron. We have already discussed this in more detail in our Intel processor history and would like to do this again in the following section for the slimmed-down Willamette and Northwood core of the Pentium 4.

A question of Cores

Even if many different processor cores had to listen to the name Celeron, they still havethey all have one thing in common: they are all castrated Pentiums, which Mendocino has left out. Here is a small overview:

The Celerons at a glance
Production L2 cache system clock socket Technologically comparable with: Pentium II Covington 0.35/0.25 no 66 MHz slot 1 Mendocino 0.25 128kB 66 MHz Slot 1/Socket 370 Technologically comparable with: Pentium III Coppermine-128 0.18 128kB 66/100 MHz Socket 370 Tualatin-256 0.13 256kB 100 MHz Socket 370 Technologically comparable with: Pentium 4 Willamette -128 0.18 128kB 400 MHz socket 478 Northwood-128 0.13 128kB 400 MHz socket 478

To sell a 'Pentium' under the Celeron label, one was robbed of one Part of the essential L2 memory and mostly gave it a lower system clock (front-side bus). While the Pentium III already worked with a FSB of 133 MHz, this was increased from 66 to 100 MHz for the Celeron. This generalization naturally also applies to the new Celerons, which are intended for the Socket 478 and are based on the Netburst architecture of the Pentium 4 .

While the first models with 1.7 and 1.8 GHz were still based on the Willamette 128 core, Intel is now making the change with the 2.0 GHz Celeron on the finer manufacturing technology, as was done with the Pentium 4 in early 2002 . This makes it possible for Intel to increase the processor speed significantly without major thermal problems and to develop a low power loss. Due to the fine production and the resulting shortened conductor tracks, the signal quality has also improved, which also reduces the processor voltage marginally from 1.565 to 1.525 voltscould. While the output voltage is completely atypical for the Willamette core, the Pentium 4 was operated here with 1.75 volts, the 1,525 of the new Celeron are typical for the new Northwood core.

Everyone who has our Read the review of the 2.8 GHz Pentium 4 carefully, you will already know what is special about the new Celeron. Because the processor core used in the 2.0GHz model is based on the very latest Northwood stepping , which was designed for clock rates up to 3 GHz and which has also been corrected for some 'erata' (errors). The Celeron 2.0GHz is therefore ideal for overclocking.
