Steven from Legion Hardware took Intel's $70 2.26GHz Celeron D 336 processor and overclocked it to 3.57GHz on air.
The point of his article is to compare the performance of this cheap CPU with a relatively much more expensive Pentium 4 processor to see how much slower this OCed budget processor is.
Rather what is important is the percentage of how much slower the Celeron D really is. Also I am not going to include a Pentium 4 630 in this overclocking article, but rather a “660”. The Pentium 4 660 is a very high-end P4 processor that costs roughly $340 US. This means if the Celeron D 336 is able to come anywhere near the Pentium 4 660 in terms of performance, it will be a real achievement. I hope you can understand why the system specifications are what they are and enjoy the results on the coming pages.
