Introduction

When we first heard that Intel would be continuing the Celeron tradition with a Prescott based "D" line, we were a little skeptical. When we further heard that the Celeron D would only be getting a quarter of the cache its underperforming Pentium 4 parent has, our eyes widened with doubt. Sure, a bump up to a 533MHz FSB would help, but it couldn't possibly make up for the kind of performance issues that we saw with the Pentium 4 E; could it?

Looking back over the past of couple months, we can almost imagine Intel knowing what everyone was thinking and going along quietly with a little smirk on its face. That's right, our first inclinations that Celeron D performance would be worse than Intel's already atrocious budget performance were utterly and completely wrong.

In fact, the new Celeron D is a big step up in performance over the Northwood-based Celeron.

We've gone from thinking that this would be a quick article on the hastening demise of the lowest value "value" chip on the market to an article about how Intel is taking a step in the right direction, while we are once again reminded that knowing the ins and outs of an architecture is no substitute for performance numbers. Of course, that was the point of requiring scaling graphs and analysis along with our simulators back in Microprocessor Architecture class.

Before getting to the numbers, we'll take a brief look back at what's inside the new Prescott based Celeron, and we'll try to understand exactly what makes Celeron D so special.

UPDATE: When this article was first published, the L2 cache size of Northwood based Celeron processors was incorrect. The information has been corrected, and the article updated accordingly. Thanks to everyone who pointed out our error. We appologize for any inconvenience we may have caused.

    I wonder what the price of these Celerons will be. I have a feeling AMD will still corner the budget market, even without the Sempron's anyway.
