Intel Celeron 420

This is a full review of the Intel Celeron 420. In this article, I will fully examine all aspects of this CPU, including its features and performance. There will also be a thorough analysis of the testing that I performed comparing this CPU to the E2140.

There are single cores, dual cores, quad cores and soon to be tricore processors. We have them available at all kinds of speeds and cache amounts. So how do you know what is best for you? It's impossible to say that this is the CPU for you without seeing what you plan to do with your computer. The quad core will surely run everything that you need, but is it too much for what you want to do? Is dual core enough or too much?

Well until now, I haven't had the chance to play with a single core processor since the old Celeron processors back on the Socket 478. A lot has changed since then and I feel that it is worth it to look at another one. Our last one overclocked very well and kept up with the Pentium 4 CPU. This time the Celeron has to try to keep up with less cache and less cores, but also run at the same speed. We will see, after some benchmarks, whether the Celeron can still keep up with its bigger counterparts.

The Celeron 420 is the beginning and end of this generation of CPUs. It will be the last single core CPU planned from Intel. After this, it's all dual cores or more, even for the Celeron bargain bin CPUs. It will be interesting to see how the dual core Celeron CPUs hold up; I hope to get a chance to test one of these when they come out.

It also marks the beginning of the Celeron CPU using the Core architecture. This alone should be a great step forward and provide a great performance gain over previous Celerons. The Netburst architecture is officially a thing of the past for Intel.
