     Intel Pentium E & Celeron 4xx

    Intel releases today new more affordable versions of the Core architecture used for the Core 2 Duo through two new product lines, the Pentium E 21x0 and Celeron 4x0. The first one are dual cores but have 1MB of L2 instead of 2 to 4 MB for the Core 2, and the second ones are single cores featuring 512 KB of L2 cache.

    The fastest of these CPU, the Pentium E 2160, is clocked at 1.8 GHz like the Core 2 E4300. The price of these new processors depends on the cache and falls from $113 to $84. This is similar to the X2 3800+and Intel now has a product to compete with it. The Pentium E 2140, priced $74 and clocked at 1.6 GHz, will compete with the 3600+.


    As usual, the influence of the L2 cache size will depend on the applications. Having "only" 1MB of L2 cache will have a much greater impact for compression or games, 5 to 10% higher performance like with 2 or 4MB, than for encoding or 3D rendering. Logically, the Pentium E will be faster than the equivalent Athlon 64 X2 when the cache size isn't too important and when it will be the case, performances will be more or less similar.

    For overclocking, results seem to depend on the products. Some of the Pentium E 21x0s are apparently stuck to 2.8 GHz and others reach up to 3.4 GHz. We will finish with one word about the Celeron 4xx: if they are even more affordable than the Pentium E, $49 for the version 430 at 1.8 GHz, but we have to keep in mind that the presence of only one core will become more and more of an handicap for applications optimized for multithreading. Considering the current dual core entry ticket, whether if it is for AMD or Intel, it would be a shame not to take advantage of it.
